GEEWIZ 3.4 SCH-I500 JZO54K JELLY BEAN 4.1.2 ROM/KERNEL
RETIRED -- GEEWIZ 3.4 WAS THE FINAL RELEASE OF GEEWIZ BASED ON ANDROID 4.1
OTHER AVAILABLE GEEWIZ VERSIONS:
GeeWiz 4 - AOSP Jelly Bean 4.2: http://forum.xda-developers.com/showthread.php?t=2088224
GeeWiz 3.4 is a ROM for the Samsung Fascinate, based on AOSP Jelly Bean 4.1. Like it's predecessors of the same name, GeeWiz doesn't aim to provide a lot of bells and whistles or incorporate all of the latest and greatest tweaks and enhancements developed by the community; the aim is to provide a basic, stable, functional device.
GeeWiz 3.4 uses a modified version of the GeeWiz 2.8 Gingerbread (Linux 2.6) kernel with a number of very specific tweaks/hacks in order to continue to support the proprietary Samsung RFS file system and other features I wanted to carry over. As a result, this ROM may not be used in conjunction with any other Kernel, and this Kernel cannot be used in conjunction with any other ROM. Please consider it a "matched set", and they will always be updated/distributed together. XDA community developed enhancements to the ROM or Kernel are encouraged, and will be given prominent feature status in this post.
Your device needs to be set up as stock or stock-like (e.g. GeeWiz 2.8) before installing this ROM/Kernel. If you are currently running with an MTD-based platform, the device must be reverted back to the original OEM volume format. Please refer to the forum/thread were you acquired your current ROM for guidance on how to revert the device as necessary.
Installing this ROM/Kernel or any other provided component(s) will void your device's warranty, and I cannot be held responsible for any damages of any kind (including data loss) that are incurred either directly or indirectly by these packages and components. What you do to your device is ultimately your problem!

CREDITS
While it would be impossible to remember/cite every possible reference that was used during development, I would like to specifically thank the following teams/individuals for making their work public so that others could learn from it and in more cases than not, shamelessly "borrow" it:
jt1134 - A primary source of knowledge for all things Samsung Fascinate
sgtkwol - Maintains a Linux 2.6 kernel for the Epic that provided a vast amount of reference material for the kernel updates
pawitp - Fixed my video driver changes to eliminate a 'microlag' issue (thank you!)
Entropy512- Customizations to allow WPA/WPA2 Wifi Tethering to work on the Galaxy S
teamhacksung - Maintains a large repository for all Galaxy S devices, I can't count how many code compares I did against their material
Cyanogenmod - The fact that this ROM can make a call at all is thanks to this team. So much of this effort is based on theirs!
rxwookie - A long-time supporter of all things GeeWiz and always takes the time to help other folks out here. I think he probably knows more about GeeWiz than I do!
ACTIVATION AND PROVISIONING
While I have no reason to believe that activation/provisioning wouldn't work properly on this ROM, it is a difficult thing to test on CDMA networks. Until it's been established that activation/provisioning is indeed working properly, I suggest you do not use anything like the ODIN "EFS Clear" option that may affect it. If the phone was properly provisioned before installing this ROM, it should maintain that provisioning. I have successfully activated a Fascinate on this ROM, but have not tested the process enough to be fully confident with it.
KNOWN ISSUES
USB Mass Storage / ADB may not work after device has been docked
After docking and removing the device from a Samsung Fascinate dock, USB Mass Storage and/or ADB may stop working. When this occurs, the only way to restore USB connectivity is to power off the device and power it back on. Rebooting is not sufficient and will not alleviate the problem.
FIRST-TIME INSTALLATION RECOMMENDATION
This ROM performs significantly better when the device uses the EXT4 file system. Unfortunately, using ODIN will always format the device with the RFS file system. Unlike previous versions of GeeWiz, the new "Full Wipe" ODIN package has been modified such that it will format the data volumes (DATA, DBDATA, CACHE) with the EXT4 file system on the first boot. This is now the recommended installation method for first-time installation.
If the "Full Wipe" ODIN package is not used, please note that your data must be wiped manually if coming from another ROM to avoid problems, and I strongly recommend converting, at minimum, the data volumes of the device (DATA, DBDATA, CACHE) to the EXT4 file system.
UPGRADING FROM GEEWIZ 3.2/3.3
GeeWiz 3.2.x/3.3.x Versions can be upgraded directly to GeeWiz 3.4 without a need to wipe the device data or revert the file system back to RFS. The EDIFY update-zip below is compatible with most, if not all, recoveries and will work regardless of if the device is formatted with RFS or EXT4.
Your Dalvik-cache will be automatically wiped, so the first reboot will take a long time
Due to problems with some Google services after a kernel change, the Google Services Framework package will have its data cleared during installation. You will be prompted to accept Google's location services again

HOW TO BUILD THE GEEWIZ 3 ROM AND KERNEL
A common request I've gotten is how to build either the GeeWiz ROM or kernel from source. I think GeeWiz 3 is a little less intimidating as a first step for getting into AOSP builds since it doesn't stray too far from the Android baseline, and the kernel is based on Samsung's stock model for the device rather than the enhanced MTD model. Whatever the reason, I'm happy to try and describe how I build these components and generate the packages that I post for the community. Sometimes it's normal, sometimes it's a bit wonky, but as long as I don't miss anything important it should be a workable process for anyone that would like to get into building custom Android builds.
I think GeeWiz 3 would be a great learning tool, it works as-is but leaves enough room for additional customizations and enhancements that it may be a better place to start than jumping into something like Cyanogenmod or AOKP as your first project. It's up to date at the moment with the latest Android code as well, so that's a definite bonus as opposed to working with something like Gingerbread where tricks you learn may not apply to the next project you take on.
BUILD ENVIRONMENT
I use Ubuntu 12.04 Desktop x64 for my Android build environment, and even though Google states that this environment is "Experimental", I've not run into any issues with it. To get started, simply follow the directions Google has provided here:
http://source.android.com/source/initializing.html
If you are running on Windows x64, I can also recommend using a Virtual Machine as your build environment. I like Oracle VirtualBox the best, but the stock Fascinate code by Samsung has major USB problems with it, you won't be able to use ADB or Heimdall. For Fascinate-specific development I recommend VMWare Player since it can work with the stock USB. Note that you need an x64 OS and a CPU with Virtualization Support to host an x64 guest OS regardless of the software you choose. The best performance and compatibility will come from installing Linux natively on your system.
DOWNLOAD GEEWIZ SOURCE TREE
Once your environment is set up, you of course need some source code. I've opted to use Google's repo tool and AOSP manifests to control the source tree, so the first thing you need is the Google repo tool. Follow the first section of this document, entitled "Installing Repo":
http://source.android.com/source/downloading.html
I have two separate "builds", or in Android terms Manifests out there. One is called DEFAULT and includes just changes to AOSP necessary to support the Fascinate. The other is called CUSTOMBUILD and adds the light OS customizations I have done. Since I never use DEFAULT and I'm not sure t even builds at the moment, we're going to use CUSTOMBUILD, or as it's called here at XDA "GeeWiz".
Open a terminal window to your home directory (~/)
mkdir android
mkdir android/platform
cd android/platform
repo init -u https://github.com/djp952/android -m custombuild.xml -b android-4.1.2_r1
What we just did was initialize the repository for AOSP, but haven't downloaded anything yet. The -u argument to repo tells it where to find the manifest XML files. In this case, my github "android" repo. The -m tells it what manifest to use. The -b tells it what branch to pull. This is important because like most folks, I have multiple branches out there. I have been indicating at the very end of the first post what the current active branch is, android-4.1.2_r1 right now.
At this point, I suggest going into the ~/android/platform/.repo/manifests directory and having a look at the manifest file. (.repo is a hidden folder). Open up custombuild.xml in GEDIT and you can see that I've taken the AOSP manifest and simply replaced portions of it to point into my own github repos for things I've changed. I'll try to include details on how I manage this below so you could do something similar if you want to.
The most time-consuming part of building Android is downloading the code. Can't go much farther without it, so get yourself a cup of coffee and a good book ...
In the terminal, at the ~/android/platform directory
repo sync
The SYNC command uses the manifest to go get all the code. Most of it is going to come from Google, but all the bits I've altered will come from my github instead. It's going to take a very long time to download.
BUILD GEEWIZ ROM
Once downloaded, we have to choose what device to build for. GeeWiz has two target devices, "atlas" and "atlas3g" (Technically, there are three as I use the same build for "toro" - VZW Galaxy Nexus). Atlas is the Wifi-only target known here as "GeeWiz Media". Atlas3G adds to that changes required to include voice/data support (mostly courtesy of Cyanogenmod!). Let's assume if you're reading this, you're interested in Atlas3G.
In the terminal, at the ~/android/platform directory
source build/envsetup.sh
lunch
The "Lunch Menu" (haha Google) will present you with a list of device builds to choose from. You can select by number, or you can type in anything not on the menu. As of this writing, the build we want is #8, full_atlas3g-userdebug. userdebug generates a generally release-quality build, but doesn't odex (pre-optimize) the APKs and has some additional debugging support you wouldn't ordinarily find. You could also type in full_atlas3g-eng for an "Engineering" build or full_atlas3g-user for a "Release" build. I think you'll prefer userdebug most of the time.
Select 8 - full_atlas3g-userdebug
make -j4 rompackage
This will kick off the build. It will take a long time the first time through. The rompackage argument is something I added to AOSP to support the Fascinate. This will build the EDIFY update-zip that I upload for everyone and use to generate the ODIN packages (more on that later). On typical Android devices, you would use otapackage (update-zip install) or updatepackage (fastboot install) instead. Fascinate is a special needs child, so it gets a special needs build process.
Once it's done, provided I didn't forget anything important here, you'll have a full ROM/Kernel package ready to be flashed via Clockworkmod or GeeWiz Recovery in the ~/android/platform/out/target/product/atlas3g folder. It will be named along the lines of full_atlas3g-rom-YYYYMMDD.HHMMSS.zip. Making a package for ODIN involves more steps, but I'll get to that. First I have to tell you how to build a modified Kernel ...
BUILDING THE GEEWIZ KERNEL
The Atlas and Atlas3G repos have a pre-compiled kernel in them that is packaged with the ROM build. This section will describe how to build and include customized versions of that kernel. First step is, of course, to get the source code. Both ROMs share a kernel but due to differences in the ramdisk (initramfs), they are built independently.
In a Terminal, at the ~/android directory
git clone https://github.com/djp952/android-kernel-atlas.git
cd android-kernel-atlas
git branch android-4.1.2_r1 remotes/origin/android-4.1.2_r1
git checkout android-4.1.2_r1
Now the build environment needs to be set up. I use the compiler provided with AOSP to build the kernel as this is how Google does it. If you are using a different compiler, or have put your AOSP tree into a different location, you may have to modify these commands slightly.
In a Terminal, at the ~/android/android-kernel-atlas directory
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-eabi-
export PATH=~/android/platform/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH
NOTE: From this point forward, don't close that Terminal, otherwise you will have to execute the environment export commands again.
The kernel is built in three steps. This is necessary because the Fascinate doesn't conform to Android's models and we have to include the ramdisk (initramfs) in the kernel image. The first step is to select which device you are building the kernel for, which in this case will be "atlas3g_defconfig". (The other configuration for GeeWiz Media is called "atlas_defconfig").
make atlas3g_defconfig
This initializes the kernel build for Atlas3G. Since we need to build the ramdisk as part of the kernel, the next step is to generate any loadable kernel module (.ko) files that need to be part of that ramdisk
make modules
The way I have the kernel set up, it will pull the necessary files for the ramdisk by looking at the device "initramfs.list" file, in the AOSP tree. The file that describes the atlas3g ramdisk, for example, is in ~/android/platform/device/samsung/atlas3g. If you examine this file you can see that it lists where all the files should come from, relative to the kernel source root directory. This explains why I went through how to build the AOSP tree before the kernel, the kernel depends on the AOSP build. Provided everything is in the right place, it's time to build the kernel
make
This executes the main kernel build. Should any ramdisk files be missing, it will error out early on and let you know what the problem is. Assuming everything goes well, your kernel will be in the ~/android/android-kernel-atlas/arch/arm/boot directory. It's named zImage and it's the combined kernel/ramdisk required for the Fascinate.
This zImage file can now be flashed directly to the device with Heimdall, packaged up for ODIN, etc. However in order to make it part of your AOSP build and corresponding EDIFY update-zip, we have to copy it into the AOSP tree and rebuild the ROM. It's a bit tedious, and other folks have different and more streamlined ways of accomplishing this, but this method has worked for me.
cp ~/android/android-kernel-atlas/arch/arm/boot/zImage ~/android/platform/device/samsung/atlas3g/kernel
cd ~/android/platform
source build/envsetup.sh
lunch full_atlas3g-userdebug
make installclean
make -j4 rompackage
This set of commands will clean out and rebuild your ROM package with the updated kernel.
CREATING ODIN PACKAGES
While not the most popular way for people to install your ROM, no guide would be complete without describing how to generate the ODIN-based installation packages. I like to provide a "Full Wipe" ODIN package that will take care of resetting the device while flashing the new ROM/Kernel, it's an easy way for people that are comfortable with ODIN to just completely replace the contents of their phone with your stuff. For this section, I'm going to assume that you are using GeeWiz Recovery, version 2.8 or later. Other recoveries will work, but as you may expect I'm most familiar with the one I made and I know for certain it has all the necessary features in place.
The ODIN factoryfs.rfs file must be generated by formatting the SYSTEM volume with RFS and then installing your ROM:
Copy your generated EDIFY update-zip to the SDCARD
Reboot into GeeWiz Recovery
Wipe the device data by selecting Wipe Device Data and then Wipe all User Data (Factory Reset)
Press the HOME key to return to the main menu
Format the SYSTEM volume with RFS by selecting Manage Volumes / Format Volumes / Format SYSTEM / Format SYSTEM [rfs]
Press the HOME key to return to the main menu
Select Install Update Package, and choose your EDIFY update-zip to install
After the installation is complete, reboot the phone by selecting Exit from the main menu. Not rebooting the device after the flash will result in a bad ODIN file more often than not. Trust me on this one.
After the device has fully booted, reboot it back into GeeWiz Recovery. The next step will be to generate a backup of the RFS-formatted SYSTEM volume to ultimately use with ODIN. GeeWiz Recovery can create these by choosing to execute a "raw dump" of the volume:
Select Manage Volumes / Backup Volumes / Backup SYSTEM / Backup SYSTEM [raw dump]
GeeWiz Recovery tries to keep volumes unmounted after it's done working, so the SDCARD must be mounted before the contents can be accessed with ADB:
Press the HOME key to return to the main menu
Select Manage Volumes / Mount Volumes / Mount SDCARD
GeeWiz Recovery will store the backup as /sdcard/backup/volume/SYSTEM-YYYYMMDD.img.gz, so as an example, I might pull it to my home folder with this command:
adb pull /sdcard/backup/volume/SYSTEM-20121022.img.gz ~/
The .gz file will contain a compressed copy of the backup, just open it up, extract the file, and then rename it to factoryfs.rfs. This is the SYSTEM volume for ODIN. There are also a number of other files you can include in your ODIN package to perform various other flash or wipe operations (I'll tell you where to get them, too)
boot.bin - Will replace the primary bootloader. VERY DANGEROUS to include, I strongly recommend against including it.
cache.rfs - Will wipe the CACHE volume; necessary if you want the device to boot into recovery automatically and run a command
dbdata.rfs - Will wipe the DBDATA volume
factoryfs.rfs - Will replace the SYSTEM volume
modem.bin - Will replace the CDMA modem
movinand.bin - Will wipe the DATA, PREINSTALL and FOTA volumes
param.lfs - Will replace the parameter block. Semi-dangerous to include, but required to ensure an initial boot into recovery mode
recovery.bin - Will replace the RECOVERY kernel and ramdisk
Sbl.bin - Will replace the secondary bootloader. VERY DANGEROUS to include, I strongly recommend against including it.
zImage - Will replace the BOOT kernel and ramdisk
To generate an ODIN-compatible tarball, gather the files you want to include and execute the following commands from a Terminal. Replace tarfilename.tar with the name you want to give the tarball, and replace file file file file with the names of the files from the table above you want to include:
tar --format=ustar -cf tarfilename.tar file file file file
md5sum -t tarfilename.tar >> tarfilename.tar
mv tarfilename.tar tarfilename.tar.md5
NOTE: If you rename the .TAR file, it will invalidate the MD5 checksum and you will have to md5sum it again.
OK, where to get the files. You can access a "full stock" ODIN package for the Fascinate, like the EH03 version that is available here on XDA to get copies of all the stock versions of these files. Or, you can use the ones from my ODIN "Full Wipe" package if you'd like as well. My ODIN tarball has a gimmick that you may find useful. If you include my copies of cache.rfs, param.lfs and recovery.bin, the device will initially reboot into recovery and automatically format the CACHE, DATA and DBDATA volumes with the EXT4 file system. It's a relatively simple trick, but an effective one to help improve the performance of your ROM. I also like to provide a "syskernel" tarball that includes only factoryfs.rfs and zImage. The benefit of this is that it will not wipe out any of your user's data. The downside is that the user may be responsible for going into Recovery on their own and executing any steps your EDIFY update-zip would have typically taken care of, like clearing the Dalvik-cache.
==================
For now, that pretty much sums it up! I can expand on this, or perhaps more appropriately compress it (I am a tad verbose!) based on feedback and how useful this little guide ends up being for everyone. Let me know -- PM me or post here in this thread, I'll see it either way!

Downloading now. Will reply with the results soon
Just have one question though. I am on a voodoo kernel ie kgb with geewiz 2.9 rom. And I will be using the edify update method to flash the 3.2 rom. Do I need to convert the file system to ext? Or can I just flash it over the existing setup.
Thanks in advance
edit...I flashed the JB rom on the above setup. The phone is stuck at the big X logo. Doesnt seem to go beyond that. So i went back to stock froyo. Then flashed GW 2.8.1. Booted properly. Everything working fine. Next i flashed geewiz recovery & converted files to ext4. rebooted. works fine too. Flashed JB rom. Phone still stuck at the X logo.
Kindly help...

Let me follow those exact steps and see what happens. Mandatory silly question: did you wipe data after installing the JB rom?
Just to clarify to make sure I do the same thing, you went back to stock Froyo (ED05), not stock Gingerbread (EH03)?
It will sit at the X logo for quite some time after flashing the ROM, since it has to dalvik all the apps. "Quite some time" in this case means like 3-5 minutes though. It does take much longer than Gingerbread to do this, but it's not some craziness like half an hour.
:crying:
edit: If I can't duplicate this, I can post a kernel update where debugging is ON by default so we could use ADB to see what it's hanging up on, but I will totally understand if you don't want to go through all that effort. Been there!
Odined back to stock. Loaded full wipe 3.2 and everything is golden. MMS, WiFi etc works great.
Did have to restart before WiFi would start. ROM is a little laggy at first but once it settles performance is on par with other JB Roms:thumbup:
Thanks Mr.GeeWiz: looks great for a "beta"
Edit: speakerphone works great also, sweet^o^

I still think in overall the ROM is laggy.
WiFi requires restart each time you switch it off.
Whatsapp is not working after SMS code verification.
Thanks DJP952
i decided to give this a try. everything works great. wifi did not require a reboot for me. camera, mms, wifi all work great. a little sluggish getting started, but pretty stable nonetheless. great work DJ. thanks

Hi djp,
I forgot to mention that I have bought the handset from Reliance (mobile service provider in India ). And that puts a limitation on me as I am not able to wipe the data dalvik and cache whenever I flash my phone to a new rom. If I do the data wipe I lose my 1x/3g Connectivity and I cannot restore it (tried various options like data fix files, apn restore etc etc) unless I flash the stock rom from Reliance (EK10 Froyo. No official gb rom for India yet ). Hence whenever I flash roms I do not wipe data. But in spite of that I have never faced any problems. Infact now the number of user apps is close to 100 and I can still flash any touchwiz rom (geewiz 2.8, 2.9, tsm resurrection and 2.2 etc without any problems. I am in no way promoting my method of not wiping but I have no other choice.
With the given restrictions that I have, please advise me how and what I can do to successfully flash JB rom. Currently there are no user apps in my device so clearing dalvik should not be a problem.

Ah, I see your point. When you had problems with activation, were you wiping data using Recovery or using the "Factory Reset" option in the OS? The latter, at least the Samsung version of it, will indeed nuke your activation. However, using Recovery to do it *shouldn't* affect anything. The activation stuff is stored in some secret location that recovery doesn't affect. I honestly have no idea where it's even stored, I used to think it was on the "EFS" volume, but as it turns out it's not!
I've never spent any real time trying to figure out a more surgical way to wipe data other than nuking the DATA and DBDATA partitions completely. Unfortunately, I don't really have the necessary knowledge to be able to do it any other way. While I'm relatively confident that wiping data through Recovery won't hurt, of course I cannot be 100% certain of that.
I apologize that I don't know enough about the non-Verizon models to be more confident in a recommendation for you. From what I know of the SCH-I500 CDMA, wiping outside of the Samsung OS, changing the modem version, or using the evil "EFS Clear" option in ODIN has never affected activation for me.
Sorry sir. Without a wipe, this one's not going to work. Just too far removed from the stock ROMs.
I can duplicate the Wifi issue and am looking into it. For me, it just took a REALLY long time for it to turn on, like 10 minutes. I think I know what I've done that might cause this and hope to fix it Getting the logs now.
edit: I think I see what the problem is, not sure why it hasn't been an issue with the "Media" version. I have to dynamically load and unload the Wifi driver to prevent bad things from happening, this isn't the usual way it's done. The OS is set up to start the Wifi "supplicant" automatically, when it probably shouldn't be. The supplicant can't load if the wifi driver isn't up yet. Sometimes it works, sometimes it doesn't, and when it doesn't Wifi will be hosed until the OS sorts it out. I have two solutions to try, the first is to see how Android behaves if I don't allow the supplicant to be started as part of the "main" service class, the second is to figure out that aforementioned bad thing and do it more properly. I'll get it. Sorry for the bug
Thanks for trying this guys! I never expected it to be as good as the "big" ROMs, and I wish I could do something about it being so ungodly slow for a while. It seems to pick up and work properly after all the apps have been updated and it's had a chance to do all the Google backups and whatnot that it wants to do.
One problem I saw yesterday for the first time that you might need to watch out for ... The battery TANKED in a matter of 2 hours for some reason. It looks like Google Search went off the reservation. I've also seen "GPS Status and Toolbox" destroy the battery if you don't close it all the way (long-press HOME, then swipe it away).
Oh, one cool feature we have now ... "Take Bug Report". Check in Settings/Developer options to see it. What this does is collect all kinds of logs and information about the phone and make an e-mail out of it. The default sends it to your GMail account. It's about 3MB, but it will be nice to have something everybody can use to gather logs for problem resolution rather than asking folks to hack around in ADB. So, if you run into weirdness, you can click that button, wait a while and watch scary "shell has been granted superuser permissions" pop up a lot, and you'll ultimately end up in GMail with something you can send you me or post parts of here! Great that Google added that in an accessible way finally!!
For the folks having trouble with turning Wifi on and off, I have an experimental/test patch for you. This patch will replace the GeeWiz 3.2 kernel with an updated version that changes the ramdisk/initramfs such that the wifi services are not started until Android requests them to be started. It may affect Wifi and Bluetooth Tethering, but my testing of the change here for both showed no ill-effects:
GeeWiz 3.2.1 Wifi Patch [Experimental] [EDIFY update-zip]
REMOVED: Please use official patch in the DOWNLOADS section of the main post
NOTE: You will be asked to re-opt-into the Google Location service on the first boot, this is normal. I clear the "Google Services Framework" app on any kernel change now to avoid the well known Jelly Bean issues with losing connection to Google Services when you alter the kernel. This may have been fixed with JZO54K, but why risk it when all you have to do is click "Agree"
You may have to reboot once more after installing this to clear up the Wifi on/off problems so that the Android settings are synchronized with the changes. If after a second reboot this does not solve your problem, please let me know!
Rollback: This change can be rolled back by installing the EDIFY update-zip for GeeWiz 3.2 again on top of it without wiping data. I can also package/provide a more specific rollback that only undoes the changes if necessary.
Please let me know if this solves your Wifi issues or not, so that I can either post it as a primary patch for GeeWiz 3.2 (and GW Media 3.2) or take another crack at solving it Thanks!!!

Ah, I see your point. When you had problems with activation, were you wiping data using Recovery or using the "Factory Reset" option in the OS? The latter, at least the Samsung version of it, will indeed nuke your activation. However, using Recovery to do it *shouldn't* affect anything. The activation stuff is stored in some secret location that recovery doesn't affect. I honestly have no idea where it's even stored, I used to think it was on the "EFS" volume, but as it turns out it's not!
I've never spent any real time trying to figure out a more surgical way to wipe data other than nuking the DATA and DBDATA partitions completely. Unfortunately, I don't really have the necessary knowledge to be able to do it any other way. While I'm relatively confident that wiping data through Recovery won't hurt, of course I cannot be 100% certain of that.
I apologize that I don't know enough about the non-Verizon models to be more confident in a recommendation for you. From what I know of the SCH-I500 CDMA, wiping outside of the Samsung OS, changing the modem version, or using the evil "EFS Clear" option in ODIN has never affected activation for me.
Sorry sir. Without a wipe, this one's not going to work. Just too far removed from the stock ROMs.

Hi!
Wiped data dalvik and cache & now I am on JellyBean. Thanks djp952. :good::good::good:
This Rom looks great and apart from the Wifi issue ( havent got time to update my phone with the patch for wifi issue as yet) which takes some time to start or sometimes just rebooted my phone altogether, everything seems to work fine. Had a problem verifying Whatsapp but used their "Verify by Call" method and now its working fine too. Battery life seems good to me as of now. Liked the inbuilt BLN.
Sadly, as i mentioned before, i lost my 1x/3g connectivity (nothing to do with this Rom) and thats Ok for a day or two till i try & figure out something to enable it again. By the way, i have always done the wipe through recovery only. Never used the factory reset option in settings menu. And that means the 1x/3g settings get wiped out the moment I wipe Data (note: wiping dalvik & cache does not affect it).
Anyways , looking forward for more developments on this rom from you.
edit... The stock gallery does not seem to show all the files available in that folder. I have 1400 plus pics in that DCIM folder and the stock gallery shows 1000 or sometimes 500 only.

We are a little off topic, but... I too have had nothing but problems with the stock Gallery application... not loading at all, not showing pictures, generally being grumpy (okay, so I get that way too sometimes), etc.
Try Quickpic (http://market.android.com/details?id=com.alensw.PicFolder) , it's a free app that is a gallery replacement (ad-free too!). Just make it the default and you should be set. If, for some reason, you don't like it... Just uninstall and revert back.
As for the Jellybean ROM... too sweet! I love having an original Galaxy S with JB running on it! I get questioned all the time what phone I have, because it's running the latest Android build and doesn't look like any out there right now.
Sent from my SCH-I500 using xda app-developers app
I'll load up some huge amount of photos and have a look at Gallery. I could switch from using the Google Nexus version to the AOSP, if it shows any improvements. One bonus we could get there is that I enabled widescreen photos in the AOSP branch Didn't include it for various reasons, one I recall was that it would crash if you tried the "face detect" option.
I'll have a look -- maybe it can be fixed! I also have to download this "Whatsapp" that people are using ... never heard of it What does it do?
Thanks as always for the feedback guys! Glad it's going pretty well thus far
FYI for any aspiring developers, I've started making a "HOW TO" guide for building GeeWiz from scratch in Post #2:
http://forum.xda-developers.com/showpost.php?p=33011164&postcount=2
I've gotten as far as how to make the AOSP ROM and compile the kernel. At minimum, I need to add how to make the ODIN files as well, but maybe later. Depending on level of interest, I can go into as much as anyone wants there, short of how to make actual code changes (but I could try to help offline). I think describing how to get from source to the flashable files is a good first step, I'll see how it goes from there
DJ, you should link this on the home page of GeeWiz 2.9, so more folks can get this. Also, I think you should name it JellyWiz...
Can I ask what this is ?

JellyBean for the Fascinate, with GeeWiz recovery and kernel

where can i find the compass?

Hello,
I want to compile Android from source. I want to just build a fully default Gingerbread that would run nice on my phone. I got the Android source, kernel source (kernel-2.6.32-U8800-Froyo) and now I don't know what to do next. I compiled the generic one already (lunch full-eng) and it ran fine on the emulator.
My most important question is, if I make it otapackage and flash it, would it start? If it doesn't, can I recover? What folders/files are essential if I make my own device for example in "device/huawei/u8800"
Also, where can I find a GOOD porting guide? I have found some that are old and not used anymore.
Some links
Start by going through source.android.com for the general basics if you havent already.
Also, even though Google removed the PDK (Platform Developer's Kit) from the site, it has been mirrored on kandroid here: http://www.kandroid.org/online-pdk/guide/index.html
The stuff in the the PDK, although inadequate, is still very important and explains how to create the necessary makefiles to add to the build, configuring for a new market, etc. etc.
Also,
watch these two videos over here. These were very helpful in my ROM development:
http://www.youtube.com/watch?v=1_H4AlQaNa0
http://www.youtube.com/watch?v=rFqELLB1Kk8
Learn to use github. It is helpful for you to keep track of your changes as well as incorporate others works into your own.
http://help.github.com/
Finally, Cyanogenmod repos are your BEST friend. Almost all major AOSP ROM devs owe some sort of thanks to those guys who have done so much. If you want to check out some of the code changes and patches that you want to incorporate look here on their gerrit:
review.cyanogenmod.com
If you want to look at the other changes that are actually in the cyanogenmod builds, best to look at their git repos here:
https://github.com/CyanogenMod
I am still learning right now while I create my ROM but your welcome to PM me if you have any questions
Glad someone helped. Now that ICS is available, I will build that instead. Now, I will follow the kandroid tutorial and add hardware_msm7x30 from cyanogenmod's repos. Then I'll make my own makefiles in the huawei/u8800 and I'll see if that works.
Also, some things I am not still clear. If I am not adding any recovery files, it shouldn't replace it, right? I want to make sure I can recover. However, my phone has a bootloader mode, which should still work, even if other's messed up. And the kernel, if I already have a compiled kernel for android 2.2, should it work for newer versions?
Thanks
Well AOSP as far as I know adds the stock recovery into the build so if you have a stock ROM, then you will lose your recovery (unless you change the source to skip the adding of recovery to otapackage).
Your bootloader should be fine. so you will theoretically be able to re-flash a custom recovery with fastboot as long as your bootloader is unlocked (assuming your phone is already rooted and has a custom rom, then it should be unlocked)
If you are using CM7 as base, then you dont have to worry about it as it is configured to NOT replace the recovery during the building and creating the otapackage.
The kernel should not be compatible as there were significant changes from Froyo and you should not use it. By the way, for now, work on the ROM first. Creating a custom kernel from scratch is hard work and should be left as the last task to do (assuming you know linux kernel development). Just use the stock pre-built kernel that comes with the source.
Also, according to Google:
Starting with IceCreamSandwich, the Android Open-Source Project can't be used from pure source code only, and requires additional hardware-related proprietary libraries to run, specifically for hardware graphics acceleration.

This means you need to find the correct hardware drivers first. Where to find that is beyond me. Check CM repos. It would be easy if everyone had a Nexus S/ Galaxy Nexus as the drivers are immediately available on source.android.com. Ah...well....
Personally, I am going to wait a few weeks before dabbling into ICS ROMs. Wait till CM7 comes out with a nightly for my nexus one and then rip the drivers from their ROM and use it for mine
I got ICS source and made the necessary Android.mk, AndroidProducts.mk, BoardConfig.mk and u8800(my device).mk, also vendorsetup.sh . Now, when I am trying to build it doesn't give me an error, more of a suggestion. It says to include "LOCAL_MODULE_TAGS := optional" in the hardware/msm7k/liblights/Android.mk. I added that, and tried again. Got that message again, but with other type /libril/Android.mk
About fastboot, I am not sure if my device has that. It can be turned on with volume up and down + power, but it boots to so called "pink screen". When I mount phone using usb to my pc, I can browse the recovery.img and other related stuff. If I have the otapackage, can I just take the recovery out from there or what should I modify in source? Add something to the makefiles?
Yeah I am pretty sure you should add the LOCAL_MODULE_TAGS to all of the relevant pre-built files. maybe they made the compiler less harsh in ICS when compared to the one for gingerbread. In gingerbread, it outright crashed the compile and asked you to add the tags.
According to Google engineers, here is the reason why they use these tags:
Short answer: lack of time.
The urgent concern was to prevent new modules from using a user tag
(implicitly or explicitly), and we took care of that. We haven't had
time to deal with the existing modules, there are over 1000 of those.

By the way, I hope you have git setup and the changes you have made are being staged and commited to your repo in github. If you ever make a mistake that hardcore crashes your compile and you dont know what you did, git will be there for you to rollback the changes as well as keep track of everything you have done from commit to commit
As far as I know, CM repos dont have everything complete for a full build of ICS but I could be wrong.
So you are working with AOSP correct?
As for the fastboot every android phone should have a fastboot by default but I believe each phone has a slightly different version. I will post how my fastboot looks like in a bit.
As for the removal of recovery, there should be somewhere in either source, makefiles or argument for the otapackage command that should leave out the recovery when making update.zip. You could just remove the recovery from the update.zip, change the updater-script and repackage it but its not a clean solution and those changes should be done in a uniform manner so you dont repeat this step every time you do a new build.
Where exactly is it, I have yet to know. Still learning much of this myself.
I now completely understand what modes of turning on my phone has... First one is normal, second is recovery, third is update-bootloader(I can access all files with it too) and four being the fastboot. The custom recovery I have on has an issue that it wants to boot to charging mode when I type "adb reboot bootloader". I can get to fastboot with the custom ROM I have on right now though. I think I am safe if I have issues.
I edited msm7k Android.mk to remove libaudio and libgralloc (errors with those), and it compiles to the step where it says it has no rule to make kernel requied by boot.img. I have put into BoardConfig.mk the line TARGET_PREBUILT_KERNEL with my kernel. I don't understand, what's wrong now...
My goal is to simply get it booting up. I'll look into libraries and other later.
-e-
Got the kernel thing sorted out. Copied device.mk from tuna device and edited to fit my device. Also modified full_u8800.mk and made the call to inherit from device.mk. Compiling now and I think I got past that.
-e2-
Got it built successfully. Fastboot won't let it install, because it has no mount points. Added mount points and let's see...
Nice to see you are making progress.
Got it built, but the fastboot is kinda buggy in my device, maybe custom rom issue. I can't make otapackage, it says "no rule to make target otapackage". I have a possible fix, trying that later.
Otherwise, I read its possible to flash system.img from recovery via advanced restore, update.zip package or advanced flash_image, but I don't know. Will post results.
Sent from my u8800

Tried make otapackage again. It still says "make: *** No rule to make target `otapackage'. Stop.". Maybe some things are still missing, I don't know. adb flash_image command will always post -1 to me, update.zip didn't work, advanced restore is not for this. I have a compiled image and I can't wait to test it, but I can't flash it...
If nothing works I'll revert to stock ROM and try again.

If you successfully compiled, take the boot.img and system.img and package them into a zip and use dsixda's kitchen to make it flashable
Blefish, is it possible for you to share your device/vendor structures somewhere? I just finished setting up a build machine for ICS (using Cyanogenmod's repos in my case), and made a working full-eng image that seems to boot just fine in the emulator, so I'm seemingly all ready to hack around our device's specifics. But I would rather not do duplicate work, so I decided to ask
I'm also grabbing Huawei's new 2.6.35-based package to get the new kernel config, can't wait for them to release the actual sources for the update.
I'll share them on GitHib once I get a working build. I haven't got much time, and I changed to CM9 alpha now (repo branch ics). Since we got a 2.3 update, my first task is to port the latest clockworkmod recovery and then the ICS.
Compiling Android is long task and I'll do it in weekends, but the recovery should be available sometime, it shouldn't be hard to port that.
Oh yeah, look up stockwell's, dzo's and genokolar's github, they have done the device configuration. You can get much help from there. This weekend I'll propably test the build, I got otapackage command working now (it needed some things I can't write on mobile).

Little in-depth information about Android. Must Read. Thank You Pirateghost.
Pirateghost said:
Android itself is OPEN. you can go and build your very own version of 4.0 ICS right now from source code. there are very few phones you can STABLY and RELIABLY run it on though.
The NEXUS line of phones exists for a reason. they are untouched by carriers (verizon teabagged the Galaxy Nexus a little), and do not have some stupid overlay on them. they are developer devices in that it is the first phone to get android updates straight from google (no manufacturer interference required).
every other phone is tainted with a manufacturer's UI. Touchwiz on Samsung phones (galaxy nexus is a samsung but they provided the hardware not the software), Sense on HTC, 'non-blur' on Motorola, whatever Sony calls theirs...lol, LG, etc
on top of that tainted Android interface is a carrier branding or lockdown (doesnt apply to the entire world, but im only referring to US here)
so google releases new version of Android
manufacturers build phone, and customize android to fit their model (this is where android almost stops being OPEN)
carriers get a hold of the manufacturers build of android and tweak and modify it themselves (more than likely they just tell the manufacturers what they want), as you know they love to include bloat and lock it down from the user
you receive your android phone after it has gone through all those steps....long process huh? we dont get updates to newer versions as quickly because of that long process...and they would rather us buy new phones instead of improving perfectly good hardware.
Android is open in the sense that manufacturers can use it however they wish, within reason. it is not necessarily meant to be 'open' to the average end user, and manufacturers dont want you messing with the phone they built. its the reason XDA is what it is today, albeit with roots deep in WinMo hacking.

ADB → Android Debug Bridge (adb) is a versatile command line tool that lets you communicate with an emulator instance or connected Android-powered device..
Android →Unveiled on 5 November 2007, Android is a mobile operating system running on the Linux kernel developed by Google.
AOSP → Android Open Source Project
Apps2SD → Move applications from the internal NAND memory on the device to a removable SD Card.
BLN → BackLight Notification
Bloatware → Software bloat is a process whereby successive versions of apps include an increasing proportion of unnecessary features that are not used by end users, or generally use more system resources than necessary, while offering little or no benefit to its users. Like all the crap that comes from At&t
Brick → When used in reference to consumer electronics, "brick" describes a device that cannot function in any capacity (such as a device with damaged firmware). This usage derives from the fact that some electronic devices (and their detachable power supplies) are vaguely brick-shaped, and so those which do not function are useful only as actual bricks. The term can also be used as a verb. For example, "I bricked my phone when I tried to modify its firmware."[
Hard Brick → When your phone does not turn on at all. When you can’t get in to CWR/CWM Or Stock recovery. You are basically screwed.
Soft Brick → When your phone bootloops. When you can get into CWR/CWM. When You can use jigtag to get into download mode.
Busybox → BusyBox provides several stripped-down Unix tools in a single executable. It runs in a variety of POSIX environments such as Linux, Android, FreeBSD and others, such as proprietary kernels, although many of the tools it provides are designed to work with interfaces provided by the Linux kernel. It was specifically created for embedded operating systems with very limited resources. Platforms counterparts, but they are pretty close and useful nonetheless.
CWR OR CWM ClockworkMod Recovery →A custom recovery for Android phones and tablets that allows you to perform several advanced recovery, restoration, installation and maintenance operations on your Android device that aren’t possible with the stock recovery.
DEODEX → Apk files have respective odexes that devs use to supposedly save space. Deodexing means you convert it back to a .dex file and put it back inside the apk. This allows you to easily replace file (not having to worry about odexes), but the main point was to deodex services.jar so that you can change all text to different colors (such as the clock color to white) and to deodex services.jar, you need to deodex everything.
Flashing → The process of applying a firmware image (or ROM) to a device. It generally entails a very specific order of steps. Failing to complete any one of these steps properly may result in bricking the device.
Firmware → is a term often used to denote the fixed, usually rather small, programs and/or data structures that internally control various electronic devices. Programs stored in the ROM, EPROM, or flash memory that usually control various internal electronic devices (Hard Drives, Keyboards, Displays, etc). Firmware is typically 'fixed' software that is not updated in consumer devices, however it is often updated (or 'flashed') by advanced users to fix bugs or add features to the device. Flashing firmware designed for one device onto a different device, or not following a specific procedure while flashing will often render the device unusable.
Kernel → is the main component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel's responsibilities include managing the system's resources (the communication between hardware and software components
Radio → The cellular radio on the device which needs control software called firmware to control it.
ROM → Read Only Memory. In the context of an Android device, ROM is the internal flash memory where the core operating system resides. It can also refer to a specific version firmware that can be applied to a device through a process usually referred to as flashing. An improperly flashed ROM can often brick the device, rendering it unusable.
Superuser→ A program, which gives unlimited access privileges to perform any or all operations on the operating system.
ODIN → Odin is the Samsung software used to update Samsung phones. It does not work with any other devices other than official Samsung phones.
OTA or FOTA → (F)OTA stands for (Firmware) Over The Air and is the process by which required updates and enhancements to your phone's basic operating system can be sent to you through the cellular network. The Galaxy S II software update will be sent via FOTA and is available through Samsung Kies mini.0
ODEX → In Android file system, applications come in packages with the extension .apk. These application packages, or APKs contain certain .odex files whose supposed function is to save space. These ‘odex’ files are actually collections of parts of an application that are optimized before booting. Doing so speeds up the boot process, as it preloads part of an application. On the other hand, it also makes hacking those applications difficult because a part of the coding has already been extracted to another location before execution.
SDK → Software Development Kit.
Logcat → A debugging tool built into Android devices that displays system logs as they occur. See Logcat.
NANDroid → A set of tools that will enable anyone who has root on their Android device to make FULL system backups, in case something goes wrong or you want to try out that new experimental ROM/theme. NANDroid will backup (and restore) /system, /data, /cache, and /boot partitions.
Recovery Mode → A special environment that you can boot into for troubleshooting and upgrading purposes.
Kang → The process of creating a code based of someone else's code or reapplying code that someone else created into your own code (e.g. git cherry-pick)
Rooting → is a process that allows users of mobile phones and other devices running the Android operating system to attain privileged control (known as "root access") within Android's Linux subsystem with the goal of overcoming limitations that carriers and manufacturers put on some devices.
How to Root Your note????
There are two root methods for YOUR ATT GALAXY NOTE!
1 which uses kernel to root.
2 This one flash with Odin but in system level not boot kernel.
#1 root by Da_G!
Da_G said:
Hi!
This kernel enables custom boot animations (/system/media/sanim.zip), adb root, init.d support, runs a script to auto-root your /system partition, and then you're on your merry way
You may need the USB Drivers available here. (Support & Downloads for SGH-I717)
Once the USB Drivers are installed, power off the phone, then hold volume down and power it on, you'll get a screen asking you to hit vol up to continue, do so. This puts the phone in download mode.
Stick the provided pda.tar in the PDA box of Odin3 1.85, flash away!
Install Superuser from the market after booting.
Note that this will increase your flash counter, which is presumably used by Samsung as a reason to decline warranty service (not aware of any reports of this occuring yet...?)

____Press install from Sd card!
_____Select the kernel that you dloaded!
______Flash it!
_______Reboot!
________Check in CPU SPY to see if you successfully flashed Kernel.
You can find Kernels in development forum.
These will set you back to Stock and Unroot Your phone.

Hi,
This is an odin .tar prepared with the stock AT&T Kernel, System, and Recovery.
Flash it from odin using the same instructions as my root thread
After flashing, you may need to boot into recovery by powering off, holding vol up + vol down, and holding power until you get into recovery. Then perform a factory reset, this should get you up and running after most brickery.
Note that this is a large file (~450MB), please spare my web host if you don't particularly need it

I'm just so young and I need your help
How do you permanently change the hostname on Android?
On CyanogenMod ROMs this is easy, there was an option for it in Applications -> Development Options. But I don't know what hooks that uses and I don't know how to do it on this flavor of Android we have.
Thanks for your post, it help me a a lot. I done a little scripting on unix using mostly tcl. I hope I can get back on it and develop a few applications for this phone once I have it on march.
Thanks!
Thanks for the noob thread. Switched over from an iP4 and its taking a little getting used to. Luckily I already had the Revue and TF101 to help a little.
On a side note I found the http://forum.xda-developers.com/showthread.php?t=1505062 root method was very easy and didnt involve the counter getting screwed up or having to flash a whole new rom. Highly recommend it for anyone just wanting to root their device.
ANother Android Newbie
Coming from IP4 and looking forward to learning hot to make Android work for me.
How do I read your "Reserveds"???
Due to being a new user, I can't reply in the Development forum, so here goes:
I have a Galaxy Player 5.0 US, and wanted to try WT's ROM (http://forum.xda-developers.com/showthread.php?t=1623529). As noted in the thread, there is a (presumably now fixed) issue with its installation. I had that same mounting issue.
So I modified the install script by commenting out the lines that unmounted, formatted, and remounted /system and uncommented the "delete-recursive" line. This provided a successful installation after making sure that the proper filesystems were mounted in CWM.
The ROM then boots successfully with Entropy's kernel, and Wi-Fi, etc. work properly--I didn't notice any issues.
As a side note to the author: would it be possible to put the kernel as one of the options in the setup?

Thanks for the feedback. I should be able to upload a new release in a day or so.
As for the kernel installation, I did consider the possibility of adding the option to install kernels but in the end I didn't put it in. My logic is that if you have a working CWM to flash this ROM, very likely you already have the correct kernel (because CWM is part of the kernel) and you rarely need to update the kernel.
If I put an option there for user to flash rj's kernel vs Entropy's kernel, I believe sooner or latter someone will flash the wrong kernel on the device which can be problematic.
If I can figure out some reliable ways to check the device type (US vs Intl), then it will be safe to include the kernel.

That sounds reasonable - installing this rom won't modify your existing kernel at all, right?
A couple of final things:
1. In your next release, could you please update GO launcher? they made some pretty big improvements
2. me being the ocd neat freak that I am, I like it when there are very few folders in the root of /sdcard. Is there a way to put the "rom-settings" folder inside something like "Android"?

GEEWIZ MEDIA 3.4 SCH-I500 JZO54K JELLY BEAN 4.1.2 ROM/KERNEL
RETIRED -- GEEWIZ MEDIA 3.4 WAS THE FINAL RELEASE OF GEEWIZ MEDIA BASED ON ANDROID 4.1
OTHER AVAILABLE GEEWIZ MEDIA VERSIONS:
GeeWiz Media 4 - AOSP Jelly Bean 4.2: http://forum.xda-developers.com/showthread.php?t=2088139
GeeWiz Media 3.4 is a Wifi-only ROM for the Samsung Fascinate, based on AOSP Jelly Bean 4.1. The goal of GeeWiz Media is to allow the Samsung Fascinate device to continue to be used as a media player-like device after it has been disconnected from cellular service. There is no support for cellular voice/data communication present in this ROM. Like it's predecessor GeeWiz, GeeWiz Media doesn't aim to provide a lot of bells and whistles or incorporate all of the latest and greatest tweaks and enhancements developed by the community; the aim is to provide a basic, stable, functional device.
GeeWiz Media 3.4 uses a modified version of the GeeWiz 2.8 Gingerbread (Linux 2.6) kernel with a number of very specific tweaks/hacks in order to continue to support the proprietary Samsung RFS file system and other features I wanted to carry over. As a result, this ROM may not be used in conjunction with any other Kernel, and this Kernel cannot be used in conjunction with any other ROM. Please consider it a "matched set", and they will always be updated/distributed together.
Your device needs to be set up as stock or stock-like (e.g. GeeWiz 2.8) before installing this ROM/Kernel. If you are currently running with an MTD-based platform, the device must be reverted back to the original OEM volume format. Please refer to the forum/thread were you acquired your current ROM for guidance on how to revert the device as necessary.
Installing this ROM/Kernel or any other provided component(s) will void your device's warranty, and I cannot be held responsible for any damages of any kind (including data loss) that are incurred either directly or indirectly by these packages and components. What you do to your device is ultimately your problem!

CREDITS
While it would be impossible to remember/cite every possible reference that was used during development, I would like to specifically thank the following teams/individuals for making their work public so that others could learn from it and in more cases than not, shamelessly "borrow" it:
jt1134 - A primary source of knowledge for all things Samsung Fascinate
sgtkwol - Maintains a Linux 2.6 kernel for the Epic that provided a vast amount of reference material for the kernel updates
pawitp - Fixed my video driver changes to eliminate a 'microlag' issue (thank you!)
teamhacksung - Maintains a large repository for all Galaxy S devices, I can't count how many code compares I did against their material
Cyanogenmod - When all else fails, if you can figure out how they are doing it ... well, it's just gonna work right.
rxwookie - A long time friend of all things GeeWiz and always picks up my slack here on the forums. I think he probably knows more about GeeWiz than I do!
KNOWN ISSUES
USB Mass Storage / ADB may not work after device has been docked
After docking and removing the device from a Samsung Fascinate dock, USB Mass Storage and/or ADB may stop working. When this occurs, the only way to restore USB connectivity is to power off the device and power it back on. Rebooting is not sufficient and will not alleviate the problem.
FIRST-TIME INSTALLATION RECOMMENDATION
This ROM performs significantly better when the device uses the EXT4 file system. Unfortunately, using ODIN will always format the device with the RFS file system. As of GeeWiz Media 3.2, the "Full Wipe" ODIN package has been modified such that it will format the data volumes (DATA, DBDATA, CACHE) with the EXT4 file system. This is now the recommended installation method for first-time installation.
If the "Full Wipe" ODIN package is not used, please note that your data must be wiped manually if coming from another ROM to avoid problems, and I strongly recommend converting, at minimum, the data volumes of the device (DATA, DBDATA, CACHE) to the EXT4 file system.
UPGRADING FROM GEEWIZ MEDIA 3.2/3.3
GeeWiz Media 3.2.x/3.3.x Versions can be upgraded directly to GeeWiz Media 3.4 without a need to wipe the device data or revert the file system back to RFS. The EDIFY update-zip below is compatible with most, if not all, recoveries and will work regardless of if the device is formatted with RFS or EXT4.
Your Dalvik-cache will be automatically wiped, so the first reboot will take a long time
Due to problems with some Google services after a kernel change, the Google Services Framework package will have its data cleared during installation. You will be prompted to accept Google's location services again

HOW TO BUILD THE GEEWIZ MEDIA 3 ROM AND KERNEL
A common request I've gotten is how to build the GeeWiz Media ROM and kernel from source. I think GeeWiz Media 3 is a little less intimidating as a first step for getting into AOSP builds since it doesn't stray too far from the Android baseline, and the kernel is based on Samsung's stock model for the device rather than the enhanced MTD model. Whatever the reason, I'm happy to try and describe how I build these components and generate the packages that I post for the community. Sometimes it's normal, sometimes it's a bit wonky, but as long as I don't miss anything important it should be a workable process for anyone that would like to get into building custom Android builds.
I think GeeWiz Media 3 would be a great learning tool, it works as-is but leaves enough room for additional customizations and enhancements that it may be a better place to start than jumping into something like Cyanogenmod or AOKP as your first project. It's up to date at the moment with the latest Android code as well, so that's a definite bonus as opposed to working with something like Gingerbread where tricks you learn may not apply to the next project you take on.
BUILD ENVIRONMENT
I use Ubuntu 12.04 Desktop x64 for my Android build environment, and even though Google states that this environment is "Experimental", I've not run into any issues with it. To get started, simply follow the directions Google has provided here:
http://source.android.com/source/initializing.html
If you are running on Windows x64, I can also recommend using a Virtual Machine as your build environment. I like Oracle VirtualBox the best, but the stock Fascinate code by Samsung has major USB problems with it, you won't be able to use ADB or Heimdall. For Fascinate-specific development I recommend VMWare Player since it can work with the stock USB. Note that you need an x64 OS and a CPU with Virtualization Support to host an x64 guest OS regardless of the software you choose. The best performance and compatibility will come from installing Linux natively on your system.
DOWNLOAD GEEWIZ SOURCE TREE
Once your environment is set up, you of course need some source code. I've opted to use Google's repo tool and AOSP manifests to control the source tree, so the first thing you need is the Google repo tool. Follow the first section of this document, entitled "Installing Repo":
http://source.android.com/source/downloading.html
I have two separate "builds", or in Android terms Manifests out there. One is called DEFAULT and includes just changes to AOSP necessary to support the Fascinate. The other is called CUSTOMBUILD and adds the light OS customizations I have done. Since I never use DEFAULT and I'm not sure t even builds at the moment, we're going to use CUSTOMBUILD, or as it's called here at XDA "GeeWiz".
Open a terminal window to your home directory (~/)
mkdir android
mkdir android/platform
cd android/platform
repo init -u https://github.com/djp952/android -m custombuild.xml -b android-4.1.2_r1
What we just did was initialize the repository for AOSP, but haven't downloaded anything yet. The -u argument to repo tells it where to find the manifest XML files. In this case, my github "android" repo. The -m tells it what manifest to use. The -b tells it what branch to pull. This is important because like most folks, I have multiple branches out there. I have been indicating at the very end of the first post what the current active branch is, android-4.1.2_r1 right now.
At this point, I suggest going into the ~/android/platform/.repo/manifests directory and having a look at the manifest file. (.repo is a hidden folder). Open up custombuild.xml in GEDIT and you can see that I've taken the AOSP manifest and simply replaced portions of it to point into my own github repos for things I've changed. I'll try to include details on how I manage this below so you could do something similar if you want to.
The most time-consuming part of building Android is downloading the code. Can't go much farther without it, so get yourself a cup of coffee and a good book ...
In the terminal, at the ~/android/platform directory
repo sync
The SYNC command uses the manifest to go get all the code. Most of it is going to come from Google, but all the bits I've altered will come from my github instead. It's going to take a very long time to download.
BUILD GEEWIZ MEDIA ROM
Once downloaded, we have to choose what device to build for. GeeWiz has two target devices, "atlas" and "atlas3g". Atlas is the Wifi-only target known here as "GeeWiz Media". Atlas3G adds to that changes required to include voice/data support (mostly courtesy of Cyanogenmod!). Let's assume if you're reading this, you're interested in the Wifi-only Atlas.
In the terminal, at the ~/android/platform directory
source build/envsetup.sh
lunch
The "Lunch Menu" (haha Google) will present you with a list of device builds to choose from. You can select by number, or you can type in anything not on the menu. As of this writing, the build we want is #9, full_atlas-userdebug. userdebug generates a generally release-quality build, but doesn't odex (pre-optimize) the APKs and has some additional debugging support you wouldn't ordinarily find. You could also type in full_atlas-eng for an "Engineering" build or full_atlas-user for a "Release" build. I think you'll prefer userdebug most of the time.
Select 9 - full_atlas-userdebug
make -j4 rompackage
This will kick off the build. It will take a long time the first time through. The rompackage argument is something I added to AOSP to support the Fascinate. This will build the EDIFY update-zip that I upload for everyone and use to generate the ODIN packages (more on that later). On typical Android devices, you would use otapackage (update-zip install) or updatepackage (fastboot install) instead. Fascinate is a special needs child, so it gets a special needs build process.
Once it's done, provided I didn't forget anything important here, you'll have a full ROM/Kernel package ready to be flashed via Clockworkmod or GeeWiz Recovery in the ~/android/platform/out/target/product/atlas folder. It will be named along the lines of full_atlas-rom-YYYYMMDD.HHMMSS.zip. Making a package for ODIN involves more steps, but I'll get to that. First I have to tell you how to build a modified Kernel ...
BUILDING THE GEEWIZ KERNEL
The Atlas and Atlas3G repos have a pre-compiled kernel in them that is packaged with the ROM build. This section will describe how to build and include customized versions of that kernel. First step is, of course, to get the source code. Both ROMs share a kernel but due to differences in the ramdisk (initramfs), they are built independently.
In a Terminal, at the ~/android directory
git clone https://github.com/djp952/android-kernel-atlas.git
cd android-kernel-atlas
git branch android-2.6 remotes/origin/android-2.6
git checkout android-2.6
Now the build environment needs to be set up. I use the compiler provided with AOSP to build the kernel as this is how Google does it. If you are using a different compiler, or have put your AOSP tree into a different location, you may have to modify these commands slightly.
In a Terminal, at the ~/android/android-kernel-atlas directory
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-eabi-
export PATH=~/android/platform/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH
NOTE: From this point forward, don't close that Terminal, otherwise you will have to execute the environment export commands again.
The kernel is built in three steps. This is necessary because the Fascinate doesn't conform to Android's models and we have to include the ramdisk (initramfs) in the kernel image. The first step is to select which device you are building the kernel for, which in this case will be "atlas_defconfig". (The other configuration for the GeeWiz 3G version is called "atlas3g_defconfig").
make atlas_defconfig
This initializes the kernel build for Atlas. Since we need to build the ramdisk as part of the kernel, the next step is to generate any loadable kernel module (.ko) files that need to be part of that ramdisk
make modules
The way I have the kernel set up, it will pull the necessary files for the ramdisk by looking at the device "initramfs.list" file, in the AOSP tree. The file that describes the atlas ramdisk, for example, is in ~/android/platform/device/samsung/atlas. If you examine this file you can see that it lists where all the files should come from, relative to the kernel source root directory. This explains why I went through how to build the AOSP tree before the kernel, the kernel depends on the AOSP build. Provided everything is in the right place, it's time to build the kernel
make
This executes the main kernel build. Should any ramdisk files be missing, it will error out early on and let you know what the problem is. Assuming everything goes well, your kernel will be in the ~/android/android-kernel-atlas/arch/arm/boot directory. It's named zImage and it's the combined kernel/ramdisk required for the Fascinate.
This zImage file can now be flashed directly to the device with Heimdall, packaged up for ODIN, etc. However in order to make it part of your AOSP build and corresponding EDIFY update-zip, we have to copy it into the AOSP tree and rebuild the ROM. It's a bit tedious, and other folks have different and more streamlined ways of accomplishing this, but this method has worked for me.
cp ~/android/android-kernel-atlas/arch/arm/boot/zImage ~/android/platform/device/samsung/atlas/kernel
cd ~/android/platform
source build/envsetup.sh
lunch full_atlas-userdebug
make installclean
make -j4 rompackage
This set of commands will clean out and rebuild your ROM package with the updated kernel.
CREATING ODIN PACKAGES
While not the most popular way for people to install your ROM, no guide would be complete without describing how to generate the ODIN-based installation packages. I like to provide a "Full Wipe" ODIN package that will take care of resetting the device while flashing the new ROM/Kernel, it's an easy way for people that are comfortable with ODIN to just completely replace the contents of their phone with your stuff. For this section, I'm going to assume that you are using GeeWiz Recovery, version 2.8 or later. Other recoveries will work, but as you may expect I'm most familiar with the one I made and I know for certain it has all the necessary features in place.
The ODIN factoryfs.rfs file must be generated by formatting the SYSTEM volume with RFS and then installing your ROM:
Copy your generated EDIFY update-zip to the SDCARD
Reboot into GeeWiz Recovery
Wipe the device data by selecting Wipe Device Data and then Wipe all User Data (Factory Reset)
Press the HOME key to return to the main menu
Format the SYSTEM volume with RFS by selecting Manage Volumes / Format Volumes / Format SYSTEM / Format SYSTEM [rfs]
Press the HOME key to return to the main menu
Select Install Update Package, and choose your EDIFY update-zip to install
After the installation is complete, reboot the phone by selecting Exit from the main menu. Not rebooting the device after the flash will result in a bad ODIN file more often than not. Trust me on this one.
After the device has fully booted, reboot it back into GeeWiz Recovery. The next step will be to generate a backup of the RFS-formatted SYSTEM volume to ultimately use with ODIN. GeeWiz Recovery can create these by choosing to execute a "raw dump" of the volume:
Select Manage Volumes / Backup Volumes / Backup SYSTEM / Backup SYSTEM [raw dump]
GeeWiz Recovery tries to keep volumes unmounted after it's done working, so the SDCARD must be mounted before the contents can be accessed with ADB:
Press the HOME key to return to the main menu
Select Manage Volumes / Mount Volumes / Mount SDCARD
GeeWiz Recovery will store the backup as /sdcard/backup/volume/SYSTEM-YYYYMMDD.img.gz, so as an example, I might pull it to my home folder with this command:
adb pull /sdcard/backup/volume/SYSTEM-20121022.img.gz ~/
The .gz file will contain a compressed copy of the backup, just open it up, extract the file, and then rename it to factoryfs.rfs. This is the SYSTEM volume for ODIN. There are also a number of other files you can include in your ODIN package to perform various other flash or wipe operations (I'll tell you where to get them, too)
boot.bin - Will replace the primary bootloader. VERY DANGEROUS to include, I strongly recommend against including it.
cache.rfs - Will wipe the CACHE volume; necessary if you want the device to boot into recovery automatically and run a command
dbdata.rfs - Will wipe the DBDATA volume
factoryfs.rfs - Will replace the SYSTEM volume
modem.bin - Will replace the CDMA modem
movinand.bin - Will wipe the DATA, PREINSTALL and FOTA volumes
param.lfs - Will replace the parameter block. Semi-dangerous to include, but required to ensure an initial boot into recovery mode
recovery.bin - Will replace the RECOVERY kernel and ramdisk
Sbl.bin - Will replace the secondary bootloader. VERY DANGEROUS to include, I strongly recommend against including it.
zImage - Will replace the BOOT kernel and ramdisk
To generate an ODIN-compatible tarball, gather the files you want to include and execute the following commands from a Terminal. Replace tarfilename.tar with the name you want to give the tarball, and replace file file file file with the names of the files from the table above you want to include:
tar --format=ustar -cf tarfilename.tar file file file file
md5sum -t tarfilename.tar >> tarfilename.tar
mv tarfilename.tar tarfilename.tar.md5
NOTE: If you rename the .TAR file, it will invalidate the MD5 checksum and you will have to md5sum it again.
OK, where to get the files. You can access a "full stock" ODIN package for the Fascinate, like the EH03 version that is available here on XDA to get copies of all the stock versions of these files. Or, you can use the ones from my ODIN "Full Wipe" package if you'd like as well. My ODIN tarball has a gimmick that you may find useful. If you include my copies of cache.rfs, param.lfs and recovery.bin, the device will initially reboot into recovery and automatically format the CACHE, DATA and DBDATA volumes with the EXT4 file system. It's a relatively simple trick, but an effective one to help improve the performance of your ROM. I also like to provide a "syskernel" tarball that includes only factoryfs.rfs and zImage. The benefit of this is that it will not wipe out any of your user's data. The downside is that the user may be responsible for going into Recovery on their own and executing any steps your EDIFY update-zip would have typically taken care of, like clearing the Dalvik-cache.

Good old me, always getting something wrong on a release Not usually fixed before any replies, but I didn't expect this ROM to be useful for than a precious few users anyway
Anyhow, it's rather important to apply the following patch, should anyone be trying this ROM out. This appears to resolve the problems with suspend/resume, including the ANR issue I mentioned above. I made customizations to the video subsystem to reduce CPU usage (by quite a bit), but didn't consider the ramifications of what happens when the screen is powered down properly. I've updated my method to be more like the original code behavior but still maintains the reduction in CPU load.

What ROM are you running now? If you're fully stock or running an MTD ROM like Cyanogenmod, I'm afraid that ODIN will be necessary. If you're running one of the community's older stock-based ROMs and have a recovery like Clockworkmod installed, shouldn't be a problem to download to the sd card, wipe data, and then install from recovery. You would just need to grab the big .zip file and the patch I just published.
Just to be sure, you saw that this ROM does not support cellular service, right? I'd hate for you to install it just to find out you have no phone!
To be honest, I would hold off until you are home and aren't going to run the risk of being without your device at all, but I'm flattered that you want to try it! Besides, my track record is always the same ... big release, big bug (check!), then a couple more bugs (hasn't happened yet, but they're there somewhere, I can feel it - LOL)
I have my old fascinate that I use as an mp3 so I'd be interested in continuing to test this for you. Maybe I'll find a way to get ISO working on the hardware so my wife can stop bugging me about hers.

I have started a full 3G version, but it will take some time and a lot of theft from Cyanogenmod to get it working. I can't promise that a full version will ever come to pass, but honestly I would prefer that than going back to update the old Gingerbread GeeWiz

What ROM are you coming from?
Booting into Recovery once is expected when you use the "fullwipe" ODIN as it contains a sneaky automatic "wipe my data" command , but that should only happen once and then boot normally.
If you were running something that uses the "MTD" partitioning that the community has developed to try and make the Fascinate work more like a standard Android device, that has to be un-done first. I'm guessing this is the problem, but if you can give me more information as to what you were previously running, perhaps I can take a look and give you more appropriate advice? That's my best off-the-cuff guess ... if you have nonstandard partitions all kinds of weird stuff can happen if you flash something that's expecting the OEM layout

Yea, I thought just Odining the partition with your Rom from work would work but I had to go ahead and Odin eh03 first. Everything works great so far.

Does it matter which version of CWM is used?
Is ODIN'ing the 3.0 fullwipe the best way to come from CM10?

No matter what your current Rom is... I would recommend ODIN'ing the stock, bloated Verizon EH03 first, get it here...
http://forum.xda-developers.com/showthread.php?p=23171859
That will reset your recovery partition and file system back to stock. Note: This is REQUIRED if you are coming from CM10 our any other AOSP Rom. Otherwise, you'll get stuck in a Recovery bootloop or worse.
From there, you can ODIN the 3.0 full wipe GeeWiz Media edition... and finally you can then ODIN any recovery you want so you can easily flash up/out (ie. CWM or DJ's own GeeWiz Recovery).
Just to repeat the warning again... this Rom has no 3g connection and has no phone AT ALL. It is basically to turn your phone into a Galaxy S Player.
Hope this helps.

Yeah, I think we have to live with some lag here and there, especially with the way I chose to implement the OS (as close to how Samsung did it as I could). I've seen some data-heavy applications really slow down on me in daily use too. The Google version of the Browser seems especially annoying, I may ultimately opt to use the AOSP one, I've been very disappointed that they haven't fixed some issues that have been around since the first Jelly Bean builds. I also have trouble occasionally with my "Sonos Controller" application ... it just gets really slow on me, and takes the rest of the device with it. At least with the Browser I can say "hey -- my Galaxy Nexus does the same thing!" lol.
But hey -- thanks for the props! I'm really glad it's coming in handy for a couple other folks out here besides myself!!
GeeWiz Media has been updated to version 3.1 and removed from "Beta" status. Version 3.1 updates the core Android platform to version JRO03R (android-4.1.1_r6), and includes a small kernel change. The updated ROM/KERNEL can be applied to an existing GeeWiz Media 3.0/3.0.1 Beta installation without the need to wipe data. I would consider this to be an "optional" update, Jelly Bean R6 didn't appear to add much that this ROM benefits from at all, and the kernel update solves a problem that may or may not be something you've even noticed.
I need to add a changelog, but here's what's new in GeeWiz Media 3.1:
- No longer considered a Beta after a week of full daily testing
- Updated kernel with patch from pawitp that addresses a "microlag" issue in my video driver
- Updated core Android OS to version JRO03R (android-4.1.1_r6)
Check the first post for the links, and THANK YOU for trying out GeeWiz Media!
PS - There have actually been more than a hundred downloads of this ROM .. wow. It's about 8% of what GeeWiz 2.8 had in it's first week (and about 2% of what GeeWiz Froyo had in it's first week!), but this is a very niche/special implementation without much mass appeal and I wasn't expecting more than 20-30 people at most. I'm very glad that the ROM has some level of usefulness even without 3G support, and I hope to steal, er... borrow, er.. implement ... the necessary stuff to make a fully enabled 3G version soon. Not sure how that will go, and this Wifi-only setup is honestly my original intention as an endgame, but we'll see! Thanks everyone! :laugh:
Brickbug Aftermath: Speeding up the Galaxy S2 i9100, S2 AT&T i777, S2 Epic 4G Touch d710 and Note n7000
UPDATE: KERNELS CAN TRIM FAT PARTITIONS
contrary to what has been said in this thread and elsewhere, the S2 TRIM kernels could always trim FAT partitions. the problem is that the FAT file system implementation does not support batch trimming (ie: fstrim), but the fact that the DISCARD mount option has always been supported on FAT has eluded us all. the mainline commit that introduced the option is here, and the corresponding code in CM's repo is here.
this means that it would probably be a good idea to add DISCARD to the default mount options of the internal sdcard in CM. deleting files from internal storage would probably become slower, but the expectation would be that overall performance should increase. the performance issues related to queue flushing that plague non-queued TRIM commands should not be a big problem in this case, since the sdcard is used mostly for media (few big files without multitasking access).
UPDATE: VICTORY !!!
2016-03-02: after two years of tests and discussions, folklore, FUD and evidence, @Lysergic Acid finally took the plunge and merged! TRIM is now part of the official CM 12.1 and CM 13.0 kernels, and this project can at last be retired, yoohoo!!! CM 13 users now enjoy TRIM out of the box, but users of CM 12.1 builds older than Match 2016 as well as CM 11.0 users continue to require a separate TRIM kernel.
this thread is dedicated to Entropy and the brave users who risked their devices to run the very first TRIM tests.
IMPORTANT NOTE FOR USERS
i am tried of lazy users sending private messages to me instead of reading the thread. i am especially tired of users asking over and over on PMs whether TRIM is safe. if you read the threads you would know: TRIM is completely safe on every supported device, stop asking! and please, never PM technical questions to anyone on XDA unless you already know the guy.
DOWNLOAD FROM -> HERE
IMPORTANT NOTE FOR KERNEL DEVELOPERS ONLY
you should not blindly merge these changes into your kernel. doing so can result in unrecoverable bricks!!! you need to check that certain patches are already merged in your kernel before enabling TRIM. please follow these steps; you can get help from this post. please contact me when in doubt, let's not revive the slumbering brickbug monster from hell, thank you!
UPDATE: CM 13.0 kernels are now available!!! (for CM 13.0-supported platforms only: i9100 and i777.)
UPDATE: several enhancements in new kernel batch:
CM 12.1 kernels are now available!!! (for CM 12.1-supported platforms only: i9100 and i777.)
kernels can now be flashed with the official, restricted cyanogen recovery that is bundled with CM 12.1.
rom-independent kernels: kernels are no longer dependent one-to-one on specific official CM builds (they might work with other roms too), and their names no longer reference a specific CM build.
although there are no official CM 11 builds for the i777, thanks to rom independence CM 11-based kernels for that device are now available.
CM 11 i9100-to-i777 cross-flash kernels for the i777 may now work with other i9100 roms besides official CM.
UPDATE: Dic 25, 2014: a holiday present!!! as kernel maintainers swiftly acted to patch PFBug, @Gustavo_s took the plunge and merged TRIM support in his latest kernel. i have verified that his kernel is as safe as mine regarding TRIM. finally a more mainstream kernel is getting this functionality, hopefully i will be able to discontinue my kernels soon!
UPDATE: great news, we have fixed FPBug!!! fixed TRIM kernels are online!
UPDATE: this project now supports all roms and kernels!
if you are not running CyanogenMod M snapshots, please see this post.
this project restores TRIM capability to CyanogenMod kernels for the Galaxy S2 family of 4210-based devices: i9100, i777, d710 and n7000. TRIM is needed to avoid "aging" of the state of the eMMC, the internal flash storage, that eventually slows the device to a crawl. TRIM functionality is built into android 4.3 and later. however, due to historical and safety concerns, TRIM capability was removed from the CM kernels for these devices (and from most if not all other AOSP-based kernels).
an in-depth discussion of this matter, including safety, risks and current state of the kernels for various devices, can be found in the main project thread. you can review that content if you are curious. get the source for this project: patches and patcher script are here (git) and base system here (repo). for instructions on how to recreate my kernels from source, see this post.
STATS: Nov 5: 500+ kernel downloads (latest version only).
Oct 1: 250+ kernel downloads (then-latest version only), top 5th thread in its forum (ThreadRank).
PROJECT STATUS: testing still needed on MAG2GA TRIM bug-affected devices before TRIM patches go mainstream. IMHO, TRIM patches are ready to be merged into mainstream kernels. kernel maintainers please read the warning at the very top of this post!
UPDATE: kernel wifi issues fixed! thanks to invaluable help from @mparus. also, ART works just fine.
What to expect
some users see big changes while others do not. there are many different eMMC models with different firmware versions embedded in these devices, and it is clear that some are faster than others. it is even possible that some eMMCs may have firmwares that completely ignore trim commands. following are some benchmarks and comments submitted by users.
@defecat0r run before-and-after benchmarks and packed it all in this neat graph (thanks so much!):

As far as i'm concerned this is safe as houses. [...] This is the biggest thing to happen to these devices since i don't know when!" (post)
@smoke2tun got better results: "My phone is blazing fast". he says: "The phone is really snappy and responsive. [...] After runing Antutu v5.1 the overall score is 17816. On NeatRom the score had an average of 11000." (post)

@Dudebowski: "[...] the increase in write ops nearly doubled! Regardless of the numbers for proof, this trim along with the floater fix [ed. note: FPBug] has made this device enjoyable to use again for the first time in years. The change in responsiveness after trim is night and day." (post)
thank you so much for the feedback and benchmarks guys!!
When things do not work
then again, some users do not get big improvements. check out the case of @desvariando.
speculation about these cases can be made. TRIM failing to provide advantages can be attributed to one of two causes:
when the fstrim command is run on some devices, it reports success but runs in zero time instead of taking the usual couple of seconds it takes on most devices. it looks like samsung disabled ERASE/TRIM support in some eMMCs, as a stopgap measure while they researched the issue further and before they output a final fix. if your eMMC trims in zero time, there is probably no realistic way to ever trim it. once your device gets slow, it can never be rejuvenated. if you fall under this group, and you have not yet ever filled the device's internal memory and your device still performs well, i would reduce the internal sdcard partition in size asap and leave a healthy sized area of 2GB inaccessible. this overprovisions the eMMC and ensures that it will never ran out of untrimmed space (assuming that the disk area you are leaving out is in fact still trimmed from factory). UPDATE: so now i know of a way to trim these untrimmable devices. it is extremely dangerous though (unless you have JTAG access to the eMMC). these eMMCs have a command to resize their boot partitions (boot0/boot1). these partitions are treated differently from all others by these modules. you can think of them as separate, safe, small, virtual disks; even if you write all over the main disk, you will never touch these partitions. also, wear leveling on the main disk will never move data around on these partitions. contrary to data on the main disk, once you write something here, it stays written forever (until you write something else). because they are treated differently, the eMMC needs to know their size. for versatility there is a non-standard command that will resize these partitions, and as a side effect it will repurpose the rest of the flash as the "main disk", creating all of its FTL structures from scratch. this full, low-level reformatting will fix a brickbug-damaged eMMC and will also trim an untrimmable device. the trick is to resize the boot partitions to some strange value, then resize them back to original size. all data everywhere will be lost, including the bootloaders, and this is why it is so dangerous. these phones will brick unless there are proper bootloaders and friends in place (though with JTAG access you could restore all this data). so the procedure would go like this: boot into recovery, make backups of all partitions you care about (bootloaders, EFS, etc), resize boot0/boot1, resize them back, and restore the needed partitions. but if anything goes wrong before you finish... you have a brick! because it is so dangerous, AFAIK this procedure has never been attempted to fix a brickbugged S2, much less to just trim one. but it has been carried on successfully on devices that boot from alternative sources when their eMMC is wiped, check it out here.
your device still had a reasonable amount of trimmed space when you installed this kernel and trimmed, and was not in need of trim. this can happen if you never filled the device's internal memory throughout its entire lifetime, or if you trimmed your device recently without knowing it. you could have trimmed by using the stock 4.1.2 kernel (which is TRIM-capable) in two ways: by wiping data from android or recovery, or by using an app such as LagFix.
otherwise, your device should be more responsive and use less battery after trimming. the need for trim is a well established reality that no FTL-based flash storage can escape.
STOP!!! DRAGONS AHEAD!!!
in theory there could be risk of hard-bricking your device forever. i believe this risk to be non-existent, based on reasons i detail in the aforementioned thread, and also based on recent experience: many people are already using these kernels without any kind of incident. however, the standard disclaimer applies: you accept full responsibility for what happens to your device.
READ and FOLLOW the instructions carefully.
Downloads
for the supported devices, you will find IsoRec-compatible CyanogenMod-based kernels here. (old kernels without IsoRec support can be found here. yet older retired kernels without FPBug fix are still available here.) note that for some supported devices, no releases or M snapshots are currently being produced. for those devices i can produce kernels based on known 'stable' nightlies if users ask.
A word about CyanogenMod 10.1.3
UPDATE: great news, we have fixed FPBug!!!
there are no CM stable releases for 4210-based devices after CM 10.1.3. the sad truth is that the kernel for these devices is broken. this affects all roms, not just CM. there seems to be some unidentified defect in the hardware itself, and no workaround for it has been implemented in the kernel so far (if such a thing is even possible). after years, @cgx finally observed the bug in action and now we at least know what we are up against. it is nasty as hell: random stack corruption. in layman's terms, any process can randomly misbehave, crash, be corrupted, corrupt data, etc... all bets are off, anything could happen. and it looks like this might never be fixed.
for whatever reason this was not much of a problem in the CM 10.1.3 days. these days, with a much more advanced and demanding android, the bug is real trouble. most people find that the last reliable CM version for their 4210-based device is 10.1.3 (including the CM team itself). i made kernels for this version, find them in the downloads section.
NOTE: the CM 10.1.3 kernels are untested. do take a nandroid! and please post your results.
Instructions
prerequisites: you need to already be running a fully official version of CyanogenMod supported by this project. (i mean fully official: dual booters, alternative kernel/recovery users, etc are not invited to this party.) you will replace your current official CM kernel with the patched, EXACT SAME VERSION kernel from this project.
download this app and run it to check if your device is affected by hardware bugs. root is requested but not needed for this test. do not trust the app's verdict! instead use the reported eMMC model name and the firmware revision (fwrev) to look up your eMMC in this table.
is your eMMC model an MAG2GA? if so you are affected by TRIM bug. WARNING: this configuration is untested. my kernels should be safe but they have never been tested on this particular eMMC, so risk cannot be completely ruled out. please read this post and decide whether you would like to test. testers are needed! i believe this is the last remaining piece of evidence needed to establish the general safety of trim on this family of devices and start pushing for its inclusion in the standard kernels, which is the ultimate objective of this project. UPDATE: things are looking much better, see this post. testing is still needed though, please help. UPDATE: MAG2GA eMMCs with fwrev 0x0E can be found in d710 devices and were tested to TRIM without problems. i personally believe this configuration to be safe.
are you affected by WL Bug? impossible. according to the available data, no 4210-based device has ever been produced with this eMMC... SO YOU MUST BE MISTAKING. please double check your situation; then post. (in any case, this bug is supposed to involve data corruption only, and not bricking.)
are you affected by Brickbug? my kernels contain samsung's fix for this bug, but samsung's fix was never exercised in practice with TRIM. i will accept ONE volunteer to test. i do not want more than one device to brick if the test fails. know that testing can potentially brick your device beyond repair. i would prefer someone with a compromised S2 (eg: lost IMEI, cracked screen) to do the first test. please post your willingness to test on this thread (include eMMC and fwrev). UPDATE: many people affected by this bug are already using my kernels without incidents. i personally believe this configuration to be safe.
if you are not affected by the previous bugs, you run no special risks by flashing my kernels.
you should start on a supported official CyanogenMod; if you are not already running it, flash it now and test it.
optional: as an extra safety step, back up your EFS and store it OUTSIDE your phone. you should have done this years ago! you never know when you might need that backup.
optional: preferably no apps should be moved to the internal sd card (check 'apps' in settings). this could slow the device a bit, but is no problem otherwise. note that apps moved to the EXTERNAL sdcard can cause BIG SLOWDOWNS.
optional: make sure you have 20% (or at the very least 10%) free space in your internal 2GB /data partition (where apps are normally installed). you will not notice speed improvements unless/until you have free space in /data.
optional: if you have been on official CM (including kernel) for a long time, and this is the first time you are going to trim your device, please contribute benchmarks. install Androbench and run all benchmarks, it takes just a few seconds. in the history section you can see most if not all results in a single screen; please take a snapshot for your before-and-after comparison.
make a nandroid backup. if you need to back out of the change for whatever reason, you will be happy to have it.
download the appropriate kernel for your CM build (includes CWM-based recovery). flash it without wiping. (at any time you can reflash official CM without wiping or upgrade to a newer CM -loosing TRIM support, of course.)
reboot.
install the LagFix (free) app from xda (the market version is declared to be incompatible with the i9100). go to the lagfix tab, check the 3 partitions, and tap on run. grant root access. the 3 fstrim operations should be successful ("partition was trimmed" means success).
UPDATE: there is a replacement app for LagFix called Trimmer that has several advantages over the former: is fully free, can schedule TRIMs, and is compatible with Android 5.
alternatively, instead of using lagfix you can run one of these commands (these are better because they also trim /preload):
# on the phone in the terminal app:
su -c "fstrim -v /system; fstrim -v /data; fstrim -v /cache; fstrim -v /preload"
# on your PC if you are connected to the phone via adb:
adb shell su -c "fstrim -v /system; fstrim -v /data; fstrim -v /cache; fstrim -v /preload"
reboot.
optional: contribute benchmarks if you qualify. run Androbench again to take an 'after' snapshot and share your before-and-after shots below.
your device should now run FAST... profit!
Please donate hardware to test
i do not have any of the supported devices to test, i am developing blind. i would gladly accept an i9100 with a cracked screen as a test bed if you can send it to an address in USA or Argentina (or any other supported device).
But wait, there's more...
Automatic trimming
android 4.3 and later should trim all writable file systems each night during charging automatically (/cache, /efs, /data and /preload). you do not need to invoke fstrim or lagfix manually again. if you want to be extra tidy you can invoke lagfix after each flash of a CM upgrade to trim /system (which is normally read-only).
because of this offline auto trimming, android 4.3 and later should not mount partitions with the discard mount option (which implements online trimming whenever space is freed), but CM does anyway. this is a bug that slows down the device and i have uploaded a patch to CM's gerrit. my kernels fix this as of Sep 14 2014.
if you use CM 10.1.3 (android 4.2.2), you might be thinking that you need to regularly trim the file systems yourself (you could use scripts or lagfix premium for automation). but as of Sep 14 2014 my kernels mount /cache, /data and /preload with the discard option, meaning that freed space on these partitions is immediately trimmed (which, again, slows down the device compared to offline trimming but is better than no trimming at all). so you only need to invoke lagfix after each flash of a CM upgrade to trim /system if you want to obsess about it. (the /efs partition is not mounted with discard; call me superstitious.) btw, i made the /preload partition writable (it is normally read-only in CM 10.1.3) so you can trim it and/or use it for whatever purpose you want. i could create 10.1.3 kernels without the discard mount option for those who wish to roll their own periodic trim feature; just ask.
The internal sdcard partition
the majority of the phone's flash is devoted to the internal sdcard partition which is formatted in a vesion of FAT. unfortunately the linux kernel file system driver for FAT is unable to trim its free space. some people format this partition to ext4 for performance and safety reasons (google). if you do that, you can fstrim it.
The preload partition
these devices have 0.5 GB ext4 /preload partition (also called "hidden"). in CyanogenMod it is unused and should be empty (you can check with the file manager). you can manually fstrim this partition (open a terminal on the phone and type: su -c "fstrim -v /preload" or from the PC via adb: adb shell su -c "fstrim -v /preload") or format it from my recovery to increase the trimmed free space in your eMMC, effectively increasing its over-provisioning by 0.5 GB. this makes the eMMC faster and extends its useful life.
UPDATE: i have removed the trim-on-format functionality (partition wiping) from the kernel patches, and thus all future kernels. there are no safety concerns with the previous kernels, but there can be problems if someone uses my patches to build a complete ROM (as opposed to just a kernel, as i have been doing). please refer to the commit for details. [Oct 3]
Adjusting partition sizes
you can repartition your phone to better distribute available flash space. i recommend vestigial /preload (unless you want to go back to stock roms later), 1 GB /system (the original 0.5 GB /system is too small for android 4.4 and gapps; 0.75 GB is enough, but the Nexus 5 comes with 1 GB, so i guess google expects it to keep growing), 6 GB /data (of which you should always keep 2 or 1 GB free to provide the eMMC with trimmable free space -remember the FAT partition does not trim), and the rest (about 8 GB) used for the internal sdcard. you can format the internal sdcard as some FAT or as ext4. (but windows does not understand ext4, but there is MTP... google!)
you can use ODIN (windows-only) or heimdall to repartition. @Roxxors contributed a nice partitioning how-to that you should read. note that he embedded my M9 kernel in his ODIN files. to create a file with the right kernel for your needs, read this.
here are some PIT files (these files are for the i9100 16 GB only, but you can use PIT Magic to roll your own):
0.5 GB system
0.75 GB system
1 GB system, 3/4/6 GB data
1 GB system, 8 GB data
1 GB system, 4 GB data, small preload
1 GB system, 6 GB data, small preload <-- this PIT is buggy!
(see attached file for a replacement i made; includes a script to repartition from linux using heimdall.)
in general, 2 GB, or even 1, of trimmable free space (ie: free space in the /data partition) will probably be more than enough to speed up your device, with rapidly diminishing gains over that.
UPDATE: due to a bug in CM, the recovery is unable to format the /preload partition. formatting is needed after repartitioning. to manually format, open a terminal on the phone and type: su -c "mkfs.ext2 /dev/block/platform/dw_mmc/by-name/HIDDEN" or from the PC via adb: adb shell su -c "mkfs.ext2 /dev/block/platform/dw_mmc/by-name/HIDDEN" (you can also use other commands such as mke2fs and mkfs.ext2.)
PLEASE NOTE: this is not a partitioning thread!!! please DO NOT seek partitioning help in this thread. please post in an appropriate thread instead. this thread is for KERNEL ISSUES ONLY. thank you!

TRIM On Other Roms And Kernels
TRIM on custom roms
when running any non-trim enabled kernel, significant speed benefits can be obtained by overprovisioning the eMMC. as long as a portion of the eMMC is in the erased state (trimmed) it will perform well, even if the kernel is not able to trim. this can be seen for example when the device is new: non-trim kernel and still the device runs nicely. as time goes on, normal usage causes the eMMC to be written all over, reducing the amount of trimmed space to zero and killing performance. this situation can be avoided in two ways: 1) by using a trim-enabled kernel that will trim space once it is no longer used by files, or 2) by setting aside an area of the eMMC and never write to it, effectively keeping it in the erased state. this second option is called overprovisioning in SSD parlance.
those of you wanting to run official CM kernels, CM nightlies, or other custom roms altogether can still obtain most of the benefits of a trim-enabled kernel without one by overprovisioning your eMMC. the stock partitioning of the 4210-based devices includes an 0.5 GB /preload partition that is just perfect for the job.
Requirements:
you have not repartitioned your device and shrank the /preload partition to enlarge other partitions.
your custom rom does not use the /preload partition. (CM does not, and I do not know of any that does... but google!)
you are not using dual-boot or other mods that use the /preload partition.
NOTE: if you have shrunk /preload and enlarged /system to 1 GB you can still follow these steps to overprovision using the free space in /system, but you will need to redo them every time you flash a new rom. otherwise, if you have an 0.5 GB /preload, you can do these steps once and just forget about the whole thing (until you flash something to the /preload partition, that is).
Instructions:
NOTE: please read step 9 now and decide if you want to use a root file manager to delete everything in /preload before you start or if you want to try to format the partition with your current recovery.
READ THIS POST IN FULL. find out which bugs your eMMC has if any, and decide whether to run the risk of trimming.
download to your device the newest trim-enabled kernel for your particular device from here.
download to your device a recovery-flashable copy of the kernel that you are currently using. (or else make a nandroid backup in step 6.)
if you want, download to your device the recovery trimmer script attached to this post. (see step 11 for more information.)
reboot to recovery.
make a nandroid backup if you do not have a flashable copy of your current kernel on your device. (make sure your nandroid is compatible with CWM-based recoveries.)
flash the trim-enabled kernel.
in the advanced section, choose reboot recovery. now you are temporarily running a trim-enabled kernel.
in the mounts and storage section, choose format /preload. (make a nandroid backup first if unsure of its contents.)
NOTE: it has been reported that format /preload does not work. this is a bug in CM's recovery. you may want to adb shell to the device to delete all files and folders under /preload, including those hidden. free space in this partition will remain trimmed when you later use the phone so it is important that most of the partition be empty after this step. (bug report)
still in the mounts and storage section, mount (if necessary) the following partitions: /system, /cache, /data and /preload.
choose one of these two options:
attach your device via USB to your PC, open a terminal, and type adb devices to verify that your device is reachable and authorized. (if it is not, under linux type adb kill-server; sudo adb devices to troubleshoot the issue; under windows try restarting the adb server from an administrator console.) in the terminal type adb shell "fstrim -v /system; fstrim -v /data; fstrim -v /cache; fstrim -v /preload" to trim. for each partition, fstrim should output a message stating the number of bytes trimmed; this indicates success.
flash the attached recovery trimmer script. you will not have any indication of success using this method. (make sure you have mounted the applicable partitions in the previous step!)
flash your old kernel back or, equivalently, restore your nandroid. (you can advance-restore only the boot partition if you want.)
reboot and profit.
TRIM on rooted stock android 4.1.2
this is beyond the scope of this project, but still some people may be interested.
Instructions:
make sure you are rooted.
WARNING: MAKE SURE YOU ARE RUNNING STOCK ANDROID VERSION 4.1.2 (THE RELEASE, NOT A LEAKED VERSION) OR YOU WILL DESTROY YOUR DEVICE DUE TO BRICKBUG!!!
READ THIS POST IN FULL. find out which bugs your eMMC has if any, and decide whether to run the risk of trimming.
WARNING: MAKE SURE YOUR EMMC IS NOT AFFECTED BY TRIM BUG OR YOU WILL DESTROY YOUR DEVICE!!! if you have trim bug, you must not trim on a stock kernel, end of story.
also, it is assumed that release (not a leak) 4.1.2 stock kernel contains this patch and thus is brickbug safe. but there might be different versions, and there is no way to be sure if the corresponding source code was patched by samsung, so...
WARNING: IF YOUR EMMC IS AFFECTED BY BRICKBUG, THE POSSIBILITY HARD BRICKING YOUR DEVICE CANNOT BE COMPLETELY RULED OUT without access to the kernel source code. proceed at your own peril, or better yet, switch to a custom rom/kernel.
install the LagFix (free) app from xda (the market version is declared to be incompatible with some 4210-based devices). go to the LagFix tab, check the 3 partitions, and tap on run. grant root access. the 3 fstrim operations should be successful ("partition was trimmed" means success). alternatively, those with busybox installed can try issuing the fstrim commands themselves. in particular, you must do this to trim /preload. you can also look for the fstrim command in the private files of LagFix.
UPDATE: there is a replacement app for LagFix called Trimmer that has several advantages over the former: is fully free, can schedule TRIMs, and is compatible with Android 5.
reboot and profit.
NOTE: i assume there is little free space in /system and /preload in stock roms, so most benefits will come from trimmed free space in /data. this space will get overwritten in time so you will need to periodically trim.
Recreating My Kernels From Source
i have been wrongly accused of not providing full source code to my kernels. to counter this accusation i am providing step-by-step instructions on how to exactly recreate any of the kernels published in this project from source. to start, all you need to know is the filename of the kernel you want to recreate. then simply follow these steps:
identify and obtain the CM release that corresponds to the kernel based on the kernel filename. example:
kernel: kernel-cm-11-20140915-NIGHTLY-Lanchon-TRIM-20140916-n7000.zip
CM release: cm-11-20140915-NIGHTLY-n7000.zipnote that nightly releases are not kept for long in CM's download servers. that is why i mirror all relevant nightlies right beside my kernels in the downloads section.
extract the build manifest (/system/etc/build-manifest.xml) from the CM release zip file.
using the manifest, checkout the source code corresponding to the release to ~/android/system by following these instructions.
identify the version of the patches that corresponds to the kernel based on the kernel filename. example:
kernel: kernel-cm-11-20140915-NIGHTLY-Lanchon-TRIM-20140916-n7000.zip
branch: cm-11
date: 20140916
tag to match: cm-11-20140916
identify the corresponding tag in my github repo and checkout its tree to ~/android/brickbug/BrickbugAftermath-SGS2. if no tag matches exactly, use the tag in the same branch that sports the closest earlier date.
run ~/android/brickbug/BrickbugAftermath-SGS2/scripts/repo-patch apply to apply the patches.
(repo-patch apply functionality used to be provided by standalone script apply in old versions.)
build the kernel using these instructions.
finally, you can run ~/android/brickbug/BrickbugAftermath-SGS2/scripts/repo-patch reset to unpatch your source tree.
(repo-patch reset functionality used to be provided by standalone script reset in old versions.)

lol brickbug
well someone will have to the guts to try. if you read the main thread (very long), i argue that it is probably safe to run my build in your phone... but then, there's only one way to know for sure

Got the same Revision (19) according to the cm table this Rom could! But not must brick our device?

i'm sorry you are affected. i personally think it would not brick (for reasons explained in the main thread, you are invited to chip in).
but i could brick! there's risk.
we will never know until somebody tests...

I think i may give it a try... Unsure if i should usw another pit? Got 2gb (stock) for now you suggestet to use 4or 6 GB? I got some Mainboards hat home with destroyed imei chips, seems to be good testers if the chip is the same :highfive:
Another question: is the fw Version of the chip upgradeable via Odin vor heimdall? Is it possible to acces the Software used by this chip?

boards with lost IMEIs? that would be great to test!!! no big loss in the worse case.
don't bother with the PIT files. just follow the main instructions. this is to test if it TRIM works without bricking in those chips. if you later want to set up a phone for real use, you can try resizing the partitions (i would for my phone).
exactly the same chip! VYLOOM 0x19 :victory: (date differs , 06/2011 but i guess this wont make a big difference at least )
edit: bootin...:fingers-crossed:
edit 2: succesfully booted,

i did dont know if there are errors if trim isnt supported or not but for now... see yourself
note : play store says lagfix app is incompatible with this device i got the app from xda

thanks! yes i'll update the app link then. those trims were successful, and yes it shows errors when you try to trim and the kernel doesn't support it.
i guess now you should use that phone and see if it bricks... for now its looking like the chances of bricking are going way down.
could you do two more tests?
try to trim /sdcard (steps in my first post)
then enable ART (debugging menu) and and see if it boot loops or not.
thanks!
no error when trimming sdcard... should i wait some more before trying art?

great! did the trim sdcard command took some time, like a second or two? or did it end absolutely immediately, like a no operation would?
no, everything checked ok, you can try ART. i think it should work. if it doesnt, wipe data from recovery (i think you are using an empty phone anyway, right?)
there was no delay after using the command.. just as you said, as if nothing happened. this is why i was wondering^^ but still not sure about this
yep the phone is empty, but i cant get into recovery or download mode .. time to set up adb
edit: device offline-.-'
edit 2: i am retarded and forgot to press the home button :')
edit 3: alrighty, now it boots but after wiping its still dalvik cache vm

hmmm... i've read somewhere the android shell sends stderr to limbo. i just tried to fstrim /sys on my nexus and not a word, exits immediately. on my linux PC it says "fstrim: /sys: FITRIM ioctl failed: Inappropriate ioctl for device".
i'll look into this further. meanwhile, are u testing ART?
EDIT: i dont know why no error is printed. but on android, if you fstrim with -v option you get text if successful:
[email protected]:/ # fstrim -v /system
/system: 0 bytes trimmed
[email protected]:/ # fstrim -v /data
/data: 2399477760 bytes trimmed
[email protected]:/ # fstrim -v /sys
1|[email protected]:/ #
so if you do fstrim -v /sdcard and you get no output, then the kernel is unable to trim FAT32. if this is the case, it would pay to find a alternate solution to this in the long run.
enabling art forces bootloop, formatting data reverts back to dalvik :silly:
no chance to use art for now^^
edit: here's a logcat but i'm not sure if it shows a normal boot or the art bootloop

thanks!
assuming official M9 has working ART, there must be some trouble with my build setup. my OpenPDroid build has the same thing, it is not related to TRIM. oh well...
your screenshot clearly shows there is no TRIM support for FAT32
i will think of what to do next. in any case, if you turn off ART and flash this on your working phone (with 20%+ free space in your internal partition) you should notice a big improvement in responsiveness and diminished lags. (a friend told me "feels like a different phone", but maybe he is exaggerating.) i still warn against doing it! i would exercise the internal storage on this phone for a while, installing big apps then deleting them, flashing the rom a couple more times, and using LagFix to trim all partitions.
or you can make a backup of your current phone and restore it here, then lagfix, and see if the increased speed justifies the risk. its your call...
for now i have nothing else to ask you to test. thank you very much!!! you've been amazing help!!!
using this on my daily phone now :good:

oops! are you sure??? i hope nothing bad happens...
after LagFix trimming and rebooting, how do you feel the phone in the way of responsiveness?
