I have managed to natively boot Urokdroid's OS in my Archos-70 device. This means that I don't need to go to the boot loader menu and select Developer to boot into my SD card which contains my Android OS. Upon power-up or reboot without pressing the volume -, I can have rooted Android OS.
First and foremost I'd like to give credits to where credits are due. I'd like to thank $aur0n for his excellent work on allowing us to boot our Archos device to external SD card. This has paved the way for many enhancements that we have now, and soon to come. I'd also like to give thanks to apr24991 for discovering a way to always boot in Developer mode. This has given me a chance to tweak my OS and allow Urokdroid's kernel to boot natively. And for all those generous people here who have willingly share their knowledge in this forum, I appreciate all your work. Now it's time for me to share what I've learned.
I'm no expert of Linux or Android. This was just based on my experience and there may be better ways to do this. Having said that, I just want to lay out some precautions.
Be prepare to lose data. So as preparation, please back-up your data.
Don't blame me if you brick your device. I would say that instructions here are easy enough for those knowledgeable in linux. However there may be few cases that you don't get the expected results. In any case, you can still restore your original Android OS by going to recovery menu and applying the stock 2.0.71 firmware from Archos.
This works on my A70, and I cannot guarantee that it will also work on A101 and other Gen8 devices. I'm suspecting it will.
After applying this successfully, you will lose the capability to dual boot. Meaning you will only be able to boot in SDE mode with rooted Android. Again you can still restore the stock firmware in the recovery menu.
Pre-requisites
Please download the SDE firmware from here. You can also download the stock 2.0.71 firmware in case you want to recover your original OS.
You should have already installed Urokdroid's kernel & this is properly working on your Archos device. In other words, you are already running Android on external SD card. $aur0n has setup a comprehensive guide here. The guide here is based on 0.3 version of Urokdroid's kernel.
Steps
Warning. On this step, you will lose all data in your device but excluding contents of external SD card. Please backup important data before continuing. Apply SDE into your Archos following phase 1 of apr24991's post here. This method will actually erase your stock Android firmware and only the SDE (AngStrom) will be present. So whenever you power on or reboot,
it will always boot AngStrom.
Now the trick now is to modify the kernel & initramfs of SDE so it will boot into external SD which contains your Android OS.
Insert your external SD card into your device.
Go to recovery menu. Press volume - while powering on.
Chose Developer Menu from the Recovery Menu.
Select flash kernel & initramfs.
Attach the device to your PC via USB. Your device will now appear as mass storage device in your PC. Copy 0.3 zImage from Urokdroid's, and the modified initramfs.cpio.gz, attached in this post (Extact it from the zip file first). This is the same initramfs.cpio.gz as Urokdroid's except I've modified /init to disable the checking of squasfs file in mmcblk0p2.
Safely unmount your device from your PC. Afterwards, select ok in your device. This would apply the copied zImage and initramfs.cpio.gz. And then it will prompt you that it will boot the device. Press power
button to reboot.
If everything is ok, you will now always be booted into Urokdroid's Android OS, rooted, and able to do other things. If you wish to restore stock firmware from Archos, just go to recovery menu and apply the firmware version you want. You may follow phase 2 of apr24991's post
here and just use your desired firmware version (2.0.54 or 2.0.71).
So far my setup is stable.
Optional: If you look at /data.old (mmcblk0p4), there is no longer data there. You have additional 300MB of partition where you can setup swap space.
Why?
You can remove the Android (Original Archos Android - not the SD-One!) in the Developer Menu in the Recovery - so no need to flash a special modified initramfs?!
Or am I missing something?
As I've mentioned, I'm no expert on Linux or Android. I've just laid out what I did. I did a lot of trial and error. If I did not flash a modified initramfs it will always boot AngStrom. What I want is to always boot on rooted Android in SD. The only thing I modified from Uruk's initramfs is to bypass the checking of squash file in /dev/mmcblk0p1. Since we reformat the device, the squash file in /dev/mmcblk0p1 has been erased. The only way to bring it back is either copy from backup or reapply the stock firmware.
I have also managed to boot a rooted Android using the built-in mmcblk0p2, mmcblk0p4 block devices. When I got to AngStrom, I just copied a backup of squash file to mmcblk0p2, and backup of data to mmcblk0p4, and then flash the kernel & initramfs from this thread. My only problem here is I'm limited to 300MB for apps.
There may be more efficient ways to do this, and if you have suggestions that will achieve the same results I'll be happy to include them in this guide.
I think I did it in a different order but it still worked.
1- SDE
2- New kernel
3- Remove "Andriod" from recovery
I liked this way since I knew the new kernel booted before I erased Archos's.

That works for sure and is the simplest way I know of.
A possible dangerous, scary way?
Thinking out loud here... but
the archos/sde bootloader is mounted by Uruk in /mnt/rawfs (currently the permissions seem to prevent write access)
rawfs contains, among other things, a file called 'custom' (which is a copy of the zImage and initramfs.cpio.gz flashed under developer edition menu and packaged together) and 'avboot', which looks to be the archos kernel/loader.
Does anyone else think it might be possible to rename custom->avboot and avboot->custom to swap both the behavior of the bootmenu and default boot around? Rooted android booting by default, stock android boots when developer edition is selected?
Ok so is there a way now that we can move the sdcard android files over to the system as a re-write-able system?
sent from epic 4g
There isn't enough space where the stock android is atm (mmcblk0)
I have put Uruk onto the internal storage (mmcblk1) because my sdcard is slow and rubbish.
so how big is the file? cant we just edited and delete some junk apps to make it enough?
I think it's possible to use mmcblk0p4 as storage for root fs. It has 300MB of space. The other partitions are too small. I'm not sure if it's possible to consolidate mmblk0 to 1 partition, but i've managed to convert mmcblk0p4 to ext4.
Update:
I consolidated mmcblk0p2, mmcblk0p3 and mmcblk0p4 into 1 ext4 partition. It's about 450MB. I put the rootfs here and use 2GB of internal storage as /data partition.
Code:
# mount

/dev/mmcblk0p2 on / type ext4 (rw,noatime,barrier=1,nodelalloc,data=ordered)

As a newer Archos buyer, I'm very happy about this info. I'd like to get some additional info tho. Firstly, you consolidated mmcblk0p2, mmcblk0p3, and mmcblk0p4 into a 400MB part for the rootfs. Were you unable to consolidate mmcblk0p1 in as well?
Secondly, you allocated 2GB of internal storage for /data, but what do you use this for? Also, this leaves you about 5GB of internal storage (as the internal storage shows approx. 7GB on my stock 101IT)? And, you're able to utilize your entire SD for storage data, as opposed to booting and keeping your OS here?
Thirdly, do you think, if necessary this could be rolled back to stock? Would a flash back to the stock ROM package restore the original partition table? The only reason I ask this, is that I've been considering selling this in a short while, when the verdict comes in on which tablets will get Gingerbread updates. Also, the pontential performance gains on a Viewsonic GTablet with it's Tegra2 based chipset intrigue me (I hadn't heard of this device when I chose my 101IT), and with it's horsepower, I think it might be a surer bet for Gingerbread love. But, if I sell it, I'd like to give my buyer an option to recieve a ROM'd/rooted or stock device depending on preference.
Lastly, as if I haven't asked enough already ;-) , could you provide detail on how one could replicate your processes? I imagine you'd start with installing SDE on your storage card to have root access to the mmcblk0 devices and install the new kernel to the consolidated mmcblk0 partition? Are there any other steps that one would need follow?
If you've read this far, thanks much for your patience and assistance!

I didn't try to include mmcblk0p1 since the boot process is still accessing this partition. One access i've seen is the flash image at boot up is taken from this partition. There may be more. So to be safe, i've excluded this partition.
Secondly, you allocated 2GB of internal storage for /data, but what do you use this for?

/data is used to be mounted to mmcblk0p4 which has about 300MB of space. I've transferred this to internal storage with 2GB, which allows me for more apps to be installed. In the internal storage, I've allocated 4.5GB as vfat (/sdcard), 2GB as ext4 (/data), and 500MB as swap.
Thirdly, do you think, if necessary this could be rolled back to stock?
Click to expand...
Click to collapse
You can always go to recovery menu, and reformat the device. This will repartition the internal storage, and install a stock firmware. This, however, will erase all your data in the internal storage.

I'll back trace my steps later, and post them here.
Here are the steps I did to use mmcblk0p1 as rootfs and a partition in mmcblk1 (internal storage).
I assume you are already on Urukdroid's kernel running on external SD.
Partitioning Internal Storage
1) I first partitioned the internal storage. To partition without destroying existing data, I used GParted from Ubuntu desktop. Connect Archos to PC running Ubuntu via USB. Mount the USB Mass Storage. A70S will appear as one of drive in Ubuntu.
2) Open GParted and select the device for the Archos internal storage. You will see 1 fat32 partition labeled A70S. Unmount the partition. Upon unmounting, you will be able to resize the partition. In my case, I put 2500 free space after the partition.
3) After resizing, I have 2500MB free space. I created 2 primary unformatted partitions, 2GB (/data), and the last one 500 (swap). After this, apply the changes in GParted.
4) Afterwards, from linux command line I formatted the 2 partitions using the following command:
Code:
mkfs.ext4 -O ^huge_file -L data /dev/sdb2
mkswap /dev/sdb3
5) Unmount USB from Archos.
Partitioning System Storage
6) Use adb shell. Unmount /dev/block/mmcblk0p4, /dev/block/mmcblk0p3, /dev/block/mmcblk0p2, /dev/block/mmcblk0p1. Using fdisk, delete partitions 2, 3, 4 from /dev/block/mmcblk0, then create 1 partition utilizing the rest of the disk space. This will give you about 450MB, that you can use as root.
7) format the partition.
Code:
mkfs.ext4 -O ^huge_file -L root /dev/block/mmcblk0p2
Copying files to the created partition
8) I mount /dev/block/mmcblk0p2 to /tmp/root, /dev/block/mmcblk1p2 to /tmp/data
Code:
mkdir /tmp/root
mkdir /tmp/data
mount -t ext4 /dev/block/mmcblk0p2
mount -t ext4 /dev/block/mmcblk1p2
8) I grabbed Urukdroid's 0.4 rootfs.tgz, and extract them mmcblk0p2.
Code:
cd /tmp/root
tar zxvf /sdcard/rootfs.tgz
9) Since 0.4 already contains Gapps, I've uninstalled Gapps first on my archos.
10) I copied the data files
Code:
cp -a /data/* /tmp/data/.
11) I modified /tmp/root/init.rc and comment out mounting /mnt/system, /cache & /data. I've attached my modified init.rc.
12) Unmount /tmp/data, and /tmp/root.
Apply kernerl & modified initramfs
13) I then rebooted to recovery, on Developer Edition Menu, flash new kernel & initramfs. Use zImage, and modified initramfs.cpio.gz which I have attached here. The modification I did in initramfs is use mmcblk0p2 as root and mmcblk1p2 as data, and if it finds /dev/mmcblk1p3 (assuming mkswap has already been applied) use it as swap.
Hope this helps.
Will this work on the 101 too?

Also curious about this
Thanks for your walkthrough! I greatly appreciate it. I'm testing this on my 101IT now. However, I seem to be boot-looping (Archos Entertainment your way screen flashes on, off, and on repeatedly). However, for the first boot of the Urukdroid kernel, it took a significant amount of time as well. I'm going to give it a few, and if there's no change, I'll retry. I may have made a mistake someplace causing this issue, so I'll see what I can dig up.

Are you following the guide from the 1st post or from the 13th post? What version of Urukdroid kernel are you using?
I was totally incorrect. When I boot with the dev edition option, I'm booting off the two internal partitions. To be honest, when I made that first post, I had been at work all night, then did this, and just didn't think to check "mount" in the terminal to see the result.
However, it's performing somewhat sluggishly. I'm unsure what's going on there. I'm going to look at some things and see what might be going on. But, the tutorial was spot on.
Is there a way to force it to boot Dev Edition (so it boots this OS) automatically upon logon?
Edit: And, I'm running the Urukdroid 0.4.1 currently, I just downloaded the latest before I began this process
On recovery menu, select Developer Edition, then select delete android's kernel. After this you'll always boot in Developer mode.

... And you would've thought that I'd have noticed that, being all the in/out of that menu I've done in the last two days...
As far as the sluggishness goes, it seems to be mostly directly after boot. After about 2 minutes, it fades, and performance improves drastically. I'm guessing it ties mostly to swappiness, and the system making initial use/caching data.
You have no idea how much of an amazing help this walkthrough has been. Just a little messing around with the file system, and moving things around, and now it's just cooking along, running an internally booted os with root access... Great work here!

Install Uruk 0.3 on second internal flash disk of Archos
UPDATE
At the last end of this guide you will find the steps necessary to upgrade to Uruk 0.6 from Uruk 0.3 or 0.4.
Near the end of this guide you will find the steps necessary to upgrade to Uruk 0.4.2 from Uruk 0.3 or to install it for the first time.
Please note.
If you are upgrading from Uruck 0.3 to 0.4.2 and installed google market hack before upgrade, after upgrade the market will be broken. To solve the problem reed the last step of this guide.
I've manage to boot from the second partition of the second internal flash of 8GB (/dev/block/mmcblk1p2) of my Archos 70IT Urukdroid vers 03 prepared by $aur0n on this post.
Thanks $aur0n for your awesome work.
It may work for other archos generation 8 too, except Archos 70 IT 250GB (i think that model doesn't have a second internal flash disk to boot from for SDE, but the owners can do it creating the 2 needed partitions on the HDD).
I've done it because:
- my micro sdcard is slow compared to internal flash
- i can mount correctly micro sdcard and second internal flash disc in Windows and linux by connecting Archos via USB and
- my sdcard is free. I can boot without sdcard in, take off from archos every time i want and upload files from a card reader or connecting the archos 70 via usb.
If you want to try it, be sure on what you are doing (linux knowledge is needed).
Try it on your own risk.
I don't have any responsibility if you brick your device (actually is hard to brick it following the guide, but pay attention please).
So if you are sure, read carefully this post and ask before if something is not clear enough for you.
I will try to answer as soon as possible (I'm actually a bit busy :-()
First of all install SDE, if you haven't already done (you can get information about it and download the SDE firmware from archos web page archos web page
Attention: Doing that You void your warranty...
Here the Archos notes:
Important notices to be acknowledged before downloading and installing the SDE firmware:
Once the SDE firmware is installed on a device, this device will be watermarked and ARCHOS will be able to detect that this firmware has been installed once.
Installing the SDE firmware is considered by ARCHOS as a voiding of the warranty and ARCHOS declines all liability and responsibility for any issues resulting from the installation of this SDE firmware.
ARCHOS strongly advises that only experts in embedded software development should install this firmware.
This firmware is provided "as is" and is not supported by ARCHOS.
Before following the steps required to install Uruk 0.3 some clarifications:
What you need to have:
- Archos 70 IT with terminal and SDE installed.
- Linux machine (nativly, visualized or LiveCD)
- Optionally Windows PC
Storage map of Archos 70 IT:
a) The first internal flash disk is of approximately 500MB (device /dev/block/mmcblk0) which is used by stock archos firmware and not changed by this guide.
Pay great attention playing with it, you may brick forever your Archos.
This flash disk have 4 partition and the block devices, mountpoints, filesystems type and size are as the following:
The first devices is "/dev/block/mmcblk0p1", mountpoint "/mnt/rawfs", type of filesystem "rawfs", size 32MB
The second devices is "/dev/block/mmcblk0p2", mountpoint "/mnt/system", type of filesystem "ext3", size 119MB
The third devices is "/dev/block/mmcblk0p3", mountpoint "/cache", type of filesystem "ext3", size 30MB
The fourth devices is "/dev/block/mmcblk0p4", mountpoint "/data" (mountpoint only by archos firmware), type of filesystem "ext3", size 300MB
b) The second internal flash disk is of approximately 7,5GB (device /dev/block/mmcblk1) which is used by this guide to boot SDE from and to accommodate the /data mountpoint (not any more on the "/dev/block/mmcblk0p4").
By stock archos firmware it has 1 partition (device /dev/block/mmcblk1p1), mountpoint "/mnt/storage", type of filesystem "fat32", size 7,5GB
After Uruk 0.3 installation it will have 3 partitions and the block devices, mountpoints, filesystems type and size will be as the following:
The first devices will be "/dev/block/mmcblk1p1", mountpoint "/mnt/storage", type of filesystem "fat32", size 5,5GB
The second devices will be "/dev/block/mmcblk1p2", mountpoint root "/", type of filesystem "ext4", size 500MB
The third devices will be "/dev/block/mmcblk1p3", mountpoint "/data", type of filesystem "ext4", size 1GB
C) The sdcard on device /dev/block/mmcblk2. On my case it have 1 partition (device /dev/block/mmcblk2p1), mountpoint "/mnt/storage/sdcard", type of filesystem "fat32".
Let's go:
The first step to do is to backup everything from your second internal flash disk (as above, it has 1 partition formated in fat32, 7,5GB capacity), just for backup purpose.
The simplest way is to connect your archos via usb to your linux box and copy directly that directory to a new directory on your linux with the default graphical file explorer of your distribution.
In my case it mounts automatically to /media/A70S (device is /dev/sdb1):
/dev/sdb1 on /media/A70S type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush)
Click to expand...
Click to collapse
If doesn't mount automatically in your case, find it using "dmesg" command on a terminal after connection complete and mount it manually.
Or you can copy it on your Windows PC (connect Archos via usb, drive mount automatically to A70S).
After backup, don't disconnect your Archos from linux. You have to resize the mounted Archos disk form 7,5GB to 5,5GB.
The easiest way is to do it graphically with your distribution partition manager utility.
First umount it by right click->umount, then resize it letting on the right side of the disk 1,5GB free space.
Create other 2 partition on that free space, first of 500MB and the other with the remaining space approx. 960MB.
Then apply the changes on the partition manager and you will have now 3 partition on the second internal flash disk of your Archos.
The first one with 5,5GB and formated on fat32, the second one 500MB not formated and the third partition of 960MB not formated.
On my case the devices are respectively /dev/sdb1, /dev/sdb2 and /dev/sdb3.
The next step is to format the second and third partition with ext4 filesystems without huge option (as from $aur0n post) on a linux terminal as root:
mkfs.ext4 -O ^huge_file /dev/sdb2
mkfs.ext4 -O ^huge_file /dev/sdb3
Click to expand...
Click to collapse
When finished, just remove safely archos from your linux box.
From the archos open a terminal and just type:
ls /dev/block/mmcblk1*
Click to expand...
Click to collapse
The result will be:
/dev/block/mmcblk1 /dev/block/mmcblk1p1 /dev/block/mmcblk1p2 /dev/block/mmcblk1p3
Click to expand...
Click to collapse
The second partition (/dev/block/mmcblk1p2) will be your new rootfs
and the third one (/dev/block/mmcblk1p3) your new application area (/data).
On this step you are going to copy all the staff on /data (device /dev/block/mmcblk0p4 mounted on /data)
to the third partition of the second internal flash (/dev/block/mmcblk1p3).
Mount the third partition first:
mkdir /tmp/data
mount /dev/block/mmcblk1p3 /tmp/data
Click to expand...
Click to collapse
and copy:
cp -rp /data/* /tmp/data
sync
umount /tmp/data
Click to expand...
Click to collapse
If you get any problems on coping (permissions) then the only way to do it correctly is to use "tar" to make a archive of data to a file on the first partition of the second internal flash disk (/dev/block/mmcblk1p1 mounted on /mnt/storage) like:
tar -cfvz /mnt/storage/data_app.tar.gz /data/
Click to expand...
Click to collapse
and then connect archos via usb to your linux computer (your three partition of the internal flash now will mount in automatic, let say /media/A70S, /media/disk1 and /media/disk2 from the devices /dev/sdb1, /dev/sdb2 and /dev/sdb3)
Now you have to extract the previous tar file (data_app.tar.gz) to the /media/disk2 (the third partition of archos internal flash disk mounted supposedly at /media/disk2):
cd /media/disk2
tar -zvxf /media/disk1/data_app.tar.gz
sync
umount /media/disk2
Click to expand...
Click to collapse
The next step, download the Uruk 0.3 version of rootfs (rootfs.tar.gz) from this link, and kernel image (zImage) from from this link on the /tmp directory of your linux box. I want to remember that this files are prepared and postet from $aur0n on this post.
If you are still connected via usb with your archos (if not, connect it),extract the rootfs (rootfs.tar.gz) directly on the mount point of the second flash partition (as above in my case is /dev/sdb2 mounted on /media/disk1) on linux:
cd /media/disk1
tar -zvxf /tmp/rootfs.tar.gz
Click to expand...
Click to collapse
Change the following lines of the init.rc file (mount point of root filesystem):
mount ext3 /dev/block/mmcblk0p4 /data noatime nosuid
# Uncomment this

and remove safely archos from the linux box and shutdown Archos.
Download the initramfs.cpio.gz_Uruk_0.3.zip from here (or from the attachment on the end of this post) and unzip it on the /tmp folder of you linux box.
Flash the initramfs.cpio.gz and zImage (remember , you downloaded zImage on the step 4 and placed it already on /tmp) on SDE environment doing:
- While power on your archos, press the "Volume -" button
- Go to "Recovery System",then "Developer Edition Menu"
- Select "Flash kernel and Initramfs".
- Attach your Archos via USB to linux computer. Archos will automatically mount, in my case is A70S_REC mounted on /media/A70S_REC/. Copy the files (initramfs.cpio.gz and zImage) from /tmp folder.
cp initramfs.cpio.gz zImage /media/A70S_REC/
Click to expand...
Click to collapse
Disconnect safely archos, then push "Ok", power and the archos will reboot.
- Press the "Volume -" to boot to the ""Boot Menu" and choose "Developer Edition" or just while booting press both "Volume -" and "Volume +" to boot directly to the "Developer Edition".
You are done.
Enjoy booting from internal flash (SDE edition).
Update: Uruk 0.4.2
There are 2 possibilities:
- You want to upgrade from Uruk 0.3
- Install Uruk 0.4.2 for the first time (You are on stock archos firmware).
Let's begin with the upgrade from Uruk 0.3 to Uruk 0.4.2
First of all download the Uruk 0.4.2 rootfs prepared from $aur0n UrukDroid-0.4.2-rootfs.rar on your linux box.
Download also UrukDroid-0.4.2-kernel.rar from here (or from the attachment on the end of this guide).
It's is $aur0n's one with the modifications to boot and mount /data from second internal flash.
Copy the above 2 files on the folder /tmp/archos of your linux machine. In my case is the 2 downloaded files are
under /home/shklifo/Download folder:
mkdir /tmp/archos
cd /tmp/archos
cp /home/shklifo/Download/UrukDroid-0.4.2-kernel.rar /home/shklifo/Download/UrukDroid-0.4.2-rootfs.rar .
Click to expand...
Click to collapse
Unrar both of them (if you don't have rar utility, just install it), giving the command:
rar x UrukDroid-0.4.2-kernel.rar
rar x UrukDroid-0.4.2-rootfs.rar
Click to expand...
Click to collapse
When the unrar process goes ok you will see the following on terminal (example of UrukDroid-0.4.2-kernel.rar):
[email protected]:/tmp/archos# rar x UrukDroid-0.4.2-kernel.rar

Click to expand...
Click to collapse
You are upgrading and you have all the applications on second internal flash disk already, so just remove the UrukDroid-copy_data.cmd, you don't need it:
rm UrukDroid-copy_data.cmd
Click to expand...
Click to collapse
Now you have to copy UrukDroid-rootfs-upgrade.tgz to the rootfs of the archos (second partition of the second internal flash disk mounted on / of type ext4 with 500MB space).
To do that just connect archos via usb to your linux box and all the tree partition of archos second internal flash will be mounted automatically.
To verify where those partition are mounted just type:
mount
Click to expand...
Click to collapse
on a linux terminal and on my case is as following:
[email protected]:/tmp/archos# mount
...
/dev/sdb1 on /media/A70S type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush)
/dev/sdb2 on /media/disk type ext4 (rw,nosuid,nodev,uhelper=hal)
/dev/sdb3 on /media/disk-1 type ext4 (rw,nosuid,nodev,uhelper=hal)
/dev/sdc1 on /media/disk-2 type vfat (rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed,flush)
Click to expand...
Click to collapse
and "df -m" like:
[email protected]:/tmp/archos# df -m
/dev/sdb1 5622 2897 2725 52% /media/A70S
/dev/sdb2 485 244 216 53% /media/disk
/dev/sdb3 973 268 656 29% /media/disk-1
/dev/sdc1 15266 1157 14110 8% /media/disk-2
Click to expand...
Click to collapse
So in my case the second partition of the second internal archos flash disk of 485MB is:
/dev/sdb2 485 244 216 53% /media/disk
Click to expand...
Click to collapse
mounted on /media/disk
Then just copy the UrukDroid-rootfs-upgrade.tgz file on the second partition of the second internal archos flash disk, like in my case:
cp /tmp/archos/UrukDroid-rootfs-upgrade.tgz /media/disk/
Click to expand...
Click to collapse
Safely disconect archos from the linux box and shutdown completely your archos.
Now you have to flash initramfs (initramfs.cpio.gz) and kernel (zImage) to your archos from "Recovery Menu" (you know already how to do it),
or if you forget it just do the following:
- While power on your archos, press the "Volume -" button
- Go to "Recovery System",then "Developer Edition Menu"
- Select "Flash kernel and Initramfs".
- Attach your Archos via USB to linux computer. Archos will automatically mount, in my case is A70S_REC mounted on /media/A70S_REC/. Copy the files (initramfs.cpio.gz and zImage) from /tmp/archos folder.
cp initramfs.cpio.gz zImage /media/A70S_REC/
Click to expand...
Click to collapse
Disconnect safely archos, then push "Ok", power and the archos will reboot.
- Press the "Volume -" to boot to the ""Boot Menu" and choose "Developer Edition" or just while booting press both "Volume -" and "Volume +" to boot directly to the "Developer Edition".
You will see the UruckDroid 0.4 screen with "Initramfs: Loading ...." than Rootfs: Loading .... and finally you will see the Uruck Desktop.
Enjoy
Install Uruk 0.4.2 for the first time
For those who whant to install Uruk 0.4.2 for the first time (now it's simplier that Uruk 0.3) will do:
a) First backup, create the partitions and filesystems on the second internal flash disk of archos (step 1
and step 2 of the Uruk 0.3).
You don't need anymore step 3 (copy of /data folder), because Uruk 0.4.2 do it automatically.
b) Then following step by step the guide Let begin with the upgrade from Uruk 0.3 to Uruk 0.4.2, except removing UrukDroid-copy_data.cmd file, because you need it to copy automatically /data files.
When you are on the step "copy the UrukDroid-rootfs-upgrade.tgz file on the second partition of the second internal archos flash disk", you need to copy additionaly UrukDroid-copy_data.cmd like:
cp /tmp/archos/UrukDroid-rootfs-upgrade.tgz /media/disk/
cp /tmp/archos/UrukDroid-copy_data.cmd /media/disk/
Click to expand...
Click to collapse
Than follow till the end the guide Let begin with the upgrade from Uruk 0.3 to Uruk 0.4.2.
Enjoy
OPTIONAL: Install google market.
If you have already istalled google market (using gAppsInstaller for example), you have to uninstall it (market/vending) first.
Then download UrukDroid-0.4.2-GoogleMarket.zip and copy it on the root (/) filesystem of archos (see above on the upgrade section an do the same steps of copying UrukDroid-rootfs-upgrade.tgz to archos rootfs).
Reboot archos.
NOTE
If you are upgrading from 0.3 version to 0.4.2 and installed before the google market from kenyu73 like i did, then the market will be broken and doesn't work any more.
To get it back, you have to remove all the google applications from SDE (Uruk 0.4.2) including the kenyu73's installer (gAppsInstaller).
Then install the market as on the previuos step OPTIONAL: Install google market downloading the file UrukDroid-0.4.2-GoogleMarket.zip and following the instructions.
After rebooting archos on SDE, you need to fix it, because you can't access the whole market (missing some "protected applications" like copilot etc).
To fix just do the following steps as kenyu73 explain on his post :
Go to Settings-->Manage Applications-->All-->Market (Clear Cache then 'Force Stop', DO NOT clear data).
Setting-->Manage Applications-->All-->Google Services Framework (Clear data then 'Force Stop').
Reboot.
Click to expand...
Click to collapse
I've done it twice the fix step, and after that no problem anymore. All the google applications (downloaded from the fresh working market) are working correctly as before.
Update: How to upgrade to Uruk 0.6 from Uruk 0.3 or 0.4.2
There are 2 possibilities:
a) The first one is the simplest one.
Just download the $auron Uruk 0.6 UrukDroid_0.6-EasyInstall.rar posted on this post, extract it on your computer and delete the file initramfs.cpio.gz, because we don't need it.
Then download the file initramfs.cpio_Uruk_0.6.gz.rar in attachment on the end of this post and extract it on the same directory of your computer (this is the initramfs that you will flash on SDE prepared from $auron and can be found on the /root/ directory of $auron new rootfs UrukDroid-install.tgz).
Then boot Archos on stock Android and connect it to your linux box via USB. The root filesystem of Archos (/dev/block/mmcblk1p2 on Archos) will be mounted on some directory on linux automatically, just find it or manually mount it (it's the filesystem with 500MB space, to be sure just type "df -h" on a terminal).
With root on a linux terminal go to that directory (in my case was /media/Disk-1) and remove all the files there:
Code:
rm -rf *
Then copy the UrukDroid-install.tgz extracted before from UrukDroid_0.6-EasyInstall.rar on the above directory.
So, you will have only the file UrukDroid-install.tgz on your rootfs directory of Uruk.
Then disconect safely Archos from your linux box and flash initramfs.cpio.gz and zImage files on SDE (you know how to do that ...) and boot to SDE.
That is
Uruk 0.6 will automatically copy everything needed as you will see on the boot time.
You have to do a last thing to be able to mount automatically the sdcard on Uruk 6. Uncomment the sdcard line on the file /system/etc/vold.fsatb like:
Code:
dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2
This is needed on the second method too (the one below).
Who want to install Uruk (version 0.6 in this case) for the first time on internal, must create and format the 2 partitions of the second internal flash disk (like on the beginning of this post described) and follow step by step the above method and at the end copy everything from the data partiotion (last partition of the first internal flash /dev/block/mmcblk0p4) to the third partition of the second flash disk (/dev/block/mmcblk1p3).
b) The second method is more complicated, but works also good.
You just install Uruk 0.6 to a sdcard like on this $auron post, than shutdown Archos, put the microsd card on a card reader connected to a linux PC and with root make a tar archive of the entire rootfs (root filesystem) of Uruk 0.6 (the second partition of the sdcard with 500MB of space on ext4 filesystem) to a tar file that you can put to the first partition of the sdcard (the fat partition of the sdcard).
Eject the sdcard and put on Archos. Turn on Archos and from a terminal on Uruk as root mount the second partition of the flash disk (/dev/block/mmcblk1p2) on a directory and just delete ("rm -rf") everything on there and then extract the tar archive there.
So, you just put everything from rootfs of the sdcard to internal flash, with correct permissions, timestamp, ownership etc.
Now just shudown Archos, take off the sdcard and boot.
This time it will Uruk 0.6 will boot from internal flash
Enjoy it
I wish I could understand more clearly how to do this with a fresh install...
This is what I am looking to do, using it on internal... but this might be a little too complicated for me.
What about 101?
Does this method applicable to Archos 101 model too?
If someone already have been tried it on 101, please reply with details here, if any troubles you have after installation or any changes need to be done.
Also I am curious about does anyone have tried to connect USB thumb drive to the tablet with modified rom and root access? Do we still have any issues with USB drive recognition?
Is this applicable for UrukDroid 4.1 and The Archos IT 35?
well great work but i dont know if i get it to work and Im a little bit confused -
is it writable in windows per media player (mtp) or per explorer or both (with ext-x driver)?

Why not. The 101 model have the second internal flash (8 or 16GB) as the 70 S model have. To be sure just type mount and df -m on a terminal in Archos device and you will see the flash drive (/dev/block/mmcblk1p1) formated in fat32 and mounted on /mnt/storage.
I only changed the mounting point on the file init, init.rc and /system/etc/vold.fstab from $aur0n files to be able to boot SDE from the second internal flash disk and doesn't change anything else, configuration file of specific model included.

I do not own your device (it is a Archos 32 IT?), but if is that model, it got a 8GB internal flash like archos 70 IT. The firmware is the same for all archos generation 8 devices (with same configuration files change), but i haven't change them (and $aur0n too i think, but he can answer himself).
So just try it, if you have no problem of understanding all the steps on the first post. You can't break anything. And if it will not work (worse case) or have other problems you just have SDE installed (you can remove it if you want) and 2 more partition on the internal flash disk with some files on them.
You can just delete the partitions and risize (increment) the first partition as from stock. In all situation we are able to boot to stock firmware.
I only change the mountpoints as i wrote in the previous posts on the files init, init.rc and vold.fstab from uruk 0.3.
So mine and $auron solution changed only on the boot partition (mine is booting form the second partition of the internal flash disk, him from the second partition of sdcard) and the application data partition (mine on the third partition of the internal the flash, him on the third partition of the sdcard). All the other files are from him (thanks $aur0n).
I've not installed yet the 0.4.1, i got little free time actually and of the market problem (if i install the 0.4.1, i must uninstall the market on stock firmware and will be not able to access it from original/stock firmware).
But if i decide to install it, i will report here.

Thanks, as i say above you don't loose anything trying to install it, only time
So, if i understand well your question, on my archos i'm able to access the first partition of the flash disk (it's a fat32 as from stock, only risezed in 5,5 GB) on my windows XP PC by usb connection to archos.
The second (boot partition 500MB) and the third (data application area of 1GB) partitions of internal flash disk are ext4 formated (stock ext3) and can't be mount on a windows PC, and for me have any sense mounting them on a PC.
The sdcard is accesible via usb connection (archos to PC) or via card reader. If you format it fat32 is in r/w mode (as i've done), ext3 or ext4 in readonly mode i think (not yet tried), because actually isn't out a driver to be able to write a linux partition on Windows.
From Ubuntu (connecting archos via usb) i can mount all in r/w mode (all the 3 partitions of the internal flash disk and sdcard too).
Later i will post some picture/command output (mount,ls) from Ubuntu.
In attachment a picture of the flash disk (A70S E: ) and sdcard (Disco rimovibile F: ) on my Windows XP macchine.

Just a suggestion.. Please be consistent with your instructions, 1 step your instructions are for linux and the next step would be for archos.
It's really hard to follow what needs to be done or how it should be done properly, considering you're messing around with the internal storage there's bigger chance of bricking your device.
I appreciate all your hard work and contributions here, it's just that it's not that user friendly.

Just to be clear, from archos terminal you have to do only 1 thing, copy or tar the "/data" mountpoint/directory, because this is the 4-th partition of the first internal flash disk (/dev/block/mmcblk0p4) and it can't be mounted on linux via usb connection.
All the other steps are from linux (the first step, you can do it from Windows too).

There are 2 internal flash disk in Archos, /dev/block/mmcblk0 of 500MB (used by archos architecture and nobody is touching this flash disk, it's dangerous and you may brick your device) and /dev/block/mmcblk1 of 8GB which is used by the this guide to boot SDE from. So, if you are able to understand what you are doing and don't touch the first flash disk, than nothing can happens.
I appreciate all your hard work and contributions here, it's just that it's not that user friendly.

With that i'm in line with your thoughs, thanks. I will try to do it more simple and understandable.
I've followed all the instructions exactly. I'm good with linux, so it wasn't very hard, but when I booted into the Developer Edition at the end, I was at the Initial Setup Screen, like it didn't mount the /data partition. Also, I can't get ES to show the file system, so it doesn't seem to be rooted. Any ideas what's going on?
EDIT: You have a typo in the init.rc the change should be to mmcblk1p3, not mmcblk1p2.
EDIT: Another typo: "dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk1" should be mmcblk2, not 1.
Now my data is there, and I can mount SD cards, but I still can't connect to a computer with a USB cable.
EDIT: All Fixed. I flashed a new kernel from http://forum.xda-developers.com/showthread.php?t=897877 and now have USB Storage working. I used the zImage from ardatdat's kernel with your initramfs.cpio.gz and the changes I listed above. Everything seems to work perfectly, and it's way faster than it was before. I was using Ardatdat's full kernel and booting from internal memory before. When I rotated the screen it used to take almost 10 seconds to update all the icons on the home screen. Now it takes less than 2-3 seconds to update. Great work on the EXT4 conversion! If you'll permit me, I'm going to write up a guide that incorporates my experience, and of course give you full credit.
Update: Just updated to UrukDroid 0.4.1. Needed a little more customization, but usb storage worked with the default 0.4.1 kernel instead of needing ardatdat's kernel. Currently testing to see which is better. Uruk says it's kernel has usb charging enabled, a very exciting possibility, but I kind of doubt it works on the A101IT.

Thanks for the corrections (you pay the needed attention), but i just modified the first post radically (easier).
Sure, you can do your own thread with your experience on the installation.
I will install Uruk 0.4.1 too, and update the first post.
WORKING
I had to add a new line into the init.rc file, but afterwards I was able to get Uruk 0.4.1 to boot internal
***mount ext4 /dev/block/mmcblk1p2 / noatime*** - I don't htink you have this in your steps...
After I did this, it works. I also am able to see both the internal and external storage in windows.
I didn't know if you need that line or it was left out of your steps process. All I did to get this to work on an existing 0.4.1 was:
1. Move the data off the internal inside windows to a saved directory on my PC.
2. Partition the 3 partitions like you describe on the internal and formated as you describe...
3. Mount the partitions inside my VMplayer Ubuntu sdb2, sdb3, sdc2, and sdc3 (sdb was the internal formated like you describe and sdc was my 16 0.4.1 SD card fromatted using uruk already)
Su terminal CODE:
$su
***password
#
#cd
#cd /tmp
#mkdir sdb2
#mkdir sdb3
#mkdir sdc2
#mkdir sdc3
#mount /dev/sdb2 /tmp/sdb2
#mount /dev/sdb2 /tmp/sdb3
#mount /dev/sdb2 /tmp/sdc2
#mount /dev/sdb2 /tmp/sdc3
4. Copy through terminal everything from sdc2 --> sdb2 using below code and Copy through terminal everything from sdc3 --> sdb3 using below code
**CODE I used:
#cp -rp /tmp/sdc2/* /tmp/sdb2
#sync
#cp -rp /tmp/sdc3/* /tmp/sdb3
#sync
6. Add in the lines inti init.rc to mount the sdb2, and the sdb3 instead of sdc2 and sdc3
mount ext4 /dev/block/mmcblk1p2 / noatime
mount ext4 /dev/block/mmcblk1p3 /data noatime
7. Add the line into tmp/sdb2/system/etc/vold.fsatb (Which is where I mounted that..)
dev_mount_lun volume_sdcard /mnt/storage/sdcard auto /devices/platform/usb_mass_storage/lun1 /class/block/mmcblk2
**I believe in 0.4.1 it is already like this, so i really made no changes to vold.fsatb....***
Unmounted all 4 I had mounted into /tmp using terminal ubuntu
CODE (I was already inside cd /tmp/sdb2 and i had edited the init.rc and saved it):
#sync
#cd..
#umount /tmp/sdb2
#umount /tmp/sdb3
#umount /tmp/sdc2
#umount /tmp/sdc3
EDIT: after this step, you will need to mount the Archos back into Windows, and copy the files you saved into a folder on your windows PC back into the Internal Fat32 storage. This was why you backed it up in the first place.... You might have to reboot and boot into your stock OS to get the internal to mount back into Windows, i did...
Reboot and go into the developer menu
Reflashed your initramfs and Uruk 0.4.1 Zimage and booted to developers edition...
***Remember this will only work if you have a preexisting 0.4.1 on an SD card where it is formatted with #1 fat32 for dtorage #2 500Mb and #3 1G and it already has been working using $auron's method.
BIG thanks to $aron and shklifo and msticninja... I am very happy using my internal memory to boot with instead of the SD card. i will prob keep the SD card I have and use it whenever I need to boot to SD and just get a different one for Videos and Music.

I really appreciate your feedback.
But you don't need to add the line:
Code:
mount ext4 /dev/block/mmcblk1p2 / noatime
on the file init.rc, because it is present on the init file included on initramfs.cpio.gz.
If you extract the initramfs.cpio.gz attached on my first post with this command on a shell:
Code:
gunzip initramfs.cpio.gz && cpio -i -d -H newc -F initramfs.cpio --no-absolute-filename
You will find the following line:
Code:
$MOUNT -t ext4 -o noatime,errors=continue /dev/mmcblk1p2 /new-root
To upgrade to $aur0n 0.4.2 now it's really simple.
I'm preparing the new initramfs.cpio.gz. And putting the new rootfs of 0.4.2 on the rootfs of our archos (just to remember it is on the second partition of the second internal disk on device /dev/block/mmcblk1p2 mountet on /) and flashing the new initramfs.cpio.gz and zimage, when booting up on "Developer Edition" it will upgrade automatically.
Is there a reason why we want to be on 0.4.2?
I am not having problems with Market, is there other benifits of this update?

BTW: Thanks for this halp on getting to internal.. I am not sure why we wanted to not do this in the first place.. I guess because some SD cards are faster, mine is working pretty fast and I think the internal is at least class 6

Just see on the $aur0n post about the new version log change. We will have upgraded module, new wifi, more services like samba sshd etc.
I to havn't any speed problem with internal flash. It is fast enough (with dd copying speed test got till 16 mbit/s write speed) on the internal flash and it is way faster than my sdcard class 4.
0.4.2
Well.. I already reverted back to the origional wifi config file using terminal, and my Market is good to go.
I'm not sure that there are any major differences between 0.4.1 --> 0.4.2
If I am wrong, i think it requires to uninstall all google apps to make that upgrade, which I don't think I need to do.
Am I wrong?

From $auron post on Uruk doesn't seem to be difference between 0.4.1 and 0.4.2, except google applications. With the 0.4.2 you can install the google staff separatly with UrukDroid-0.4.2-GoogleMarket.rar. If you have those apps allready on your 0.4.1 than nothing change, you don't need to upgrade.
Thanks and no problem with your methods.
My 16GB microSD card isn't very good and boot / use of archos 101 is very slow with Uruk0.4.2 installed on external SD.
Now it's fast installed on internal SD...
Maybe this help:
if can't mount ext4 partition on your linux box, you can do:
tune2fs -E test_fs /dev/sdbx (sdb2 for instance)
and then:
mount -t ext4dev /dev/sdbx /mnt/sdcard
trouble with fresh install for 0.4.2 $auron....
I was able to create 3 partition internally (sdb1(vfat), sdb2(ext4), sdb3(ext4))
I was able to move rootfs and cmd script to sdb2
I was able to flash initramfs and zImage
But I'm stuck when rebooting into SDE (the screen is all messed up)
Any suggestion?
I didn't modify init.rc and vold.stab since this is a fresh install

Does this method applicable to Archos 101 model too?
If someone already have been tried it on 101, please reply with details here, if any troubles you have after installation or any changes need to be done.
Also I am curious about does anyone have tried to connect USB thumb drive to the tablet with modified rom and root access? Do we still have any issues with USB drive recognition?

Yes this procedure works the same way on the A101. I have the 16GB version so I made the 1st partition a bit bigger but that was the only deviation.
Manually set variables as shown below
NOTE: I have found out that the Atrix also uses the name Mapphone_cdma in place of Olympus in their code. Why I do not know... I have noticed that the log.txt generated by bootmanager after repackaging the boot.img says that it cannot find a file named init.olympus.rc BUT shows no error with init.Mapphone_cdma.rc
NOTE: So far only works with CM7 as being the Phone ROM. I tried other ROM's as the phone ROM and I get a lot of errors.. I think it might be because of the structure of the CM7..

The cache size can be reduced to as low as 200mb and the data size I would go as low as 500mb. The only one that should stay UN-modified is the System size..
Follow these steps to get a successful install/force close error galore!
Boot into CWM
Make a backup of your current ROM
Boot your phone back up
Use Root explore, File Manager or what ever File browser you'd like to use
copy the boot.img from /sdcard/clockworkmod/backup/nameofyourbackup
to /sdcard/BootManager/phoneRom (Thanks to hatefuel19 for his discovery. Fix found Here!)
Start BootManager and now select "Setup Phone ROM"
(Should say successful, If not go back to step 4)
Go to "install Zips", then select ROM of your choice.
Select "Wipe System", "Wipe Data", "Wipe Cache" and select "Sot1"
(Wait for install to complete..........................)
Download the file from down below named "BootManager-rom1-Atrix.zip"
place "BootManager-rom1-Atrix.zip" in the slot1 folder replacing the update.zip (<---delete)
(it is not necessary to rename "BootManager-rom1-Atrix" to "update" but you can if you want)
Now that you have replaced the file boot back into CWM
select "zip from sdcard"
select "install zip from sdcard"
select "external sdcard"
Navigate to BootManager
select "Rom1"
select "BootManager-rom1-Atrix.zip"
***At this point you will now have a successful install***
(This does not mean it will boot up successfully, you will still get errors no matter what ROM your using)
I have done some research and talked to the dev of init2winit and when it shows the block being busy or not available that is because it's mounted.. Doh!! lol I didn't even think of that..
If you choose to boot the phone up "as is" (meaning whatever ROM you are using) you will get stuck at the moto-boot screen or it will boot up into the ROM and everything will force close on you. To get it back to normal just go;
back into CWM
select "backup/restore"
select "advanced restore"
and all you have to restore is the boot.img
****About the two files uploaded****
"BootManager-rom1-Atrix (original).zip"
This is a modified update.zip by init2winit just for the Atrix. But this one is lacking one file that is crucial for the phone to recognize the install
"BootManager-rom1-Atrix.zip"
This file contains everything that "BootManager-rom1-Atrix (original).zip" has but I replaced the the update-binary located in the zip under \META-INF\com\google\android with one from the Alien #4 ROM because the update-binary has information sensitive to our phone (do not touch the updater-script it has information to keep the ROM from installing over your current Phone ROM)
***Question For a Dev***
I uploaded both the .txt files that are generated by bootmanager and recovery. at the bottom of the log.txt it says the following errors;
blocks
cp: can't stat '/data/local/tmp/system/lib/modules/ext2.ko': No such file or directory
cp: can't stat '/data/local/tmp/system/lib/modules/mbcache.ko': No such file or directory
sed: /data/local/tmp/boot.img-ramdisk/init.vivow_ct.rc: No such file or directory
sed: /data/local/tmp/boot.img-ramdisk/init.vivow_ct.rc: No such file or directory
sed: /data/local/tmp/boot.img-ramdisk/init.vivow_ct.rc: No such file or directory
What are these files and are they named something different on the Atrix?
That is a normal error, it is part of a script for another phone but will not hinder the install in anyway on ours.
Disclaimer: Neither I nor anyone else is responsible if you brick, break or blow up your Atrix. Everything that YOU do is at YOUR OWN RISK!!
STILL in the process of getting the Atrix supported with BootManager
All Credit goes to Init2Winit Applications for the creation of this Awesome APP!
I'm in the process of getting The Olympus (Atrix) supported.

It should work with any ROM with the new installer and edify scripts.
So in the meantime, does anyone know have a line on the Atrix' settings for manual setup?

Yes, they outline the steps for the "How to" on manual setup but unfortunately I tried that already and it does not work. It's taking init2winit some time to get us support and I suppose that's because our phone is one hell-of-a beast to tame

thanks for the info! I'm curious what rom you tried it on/with. I noticed this morning when I flashed CM7-PB2 that it moved the internal SDcard to mnt/emmc... I wonder if changing where the SD card mounts could break the operation of the program. were you using the internal SD, or an external SD? Sorry if it sounds like the Spanish inquisition, I'm just picking your brain so I can start trying different configurations; maybe with a little trial and error we can get it working...

Well I tried using internal and external SD card on both Ninja SF ROM by samcripp and Alien #2 by Kennethpenn. I have not flashed CM7 as I am waiting for a more stable build. Let me know how it goes for you though

Also, is it normal to have to reflash my recovery every time I want to use it? Right after flashing it works great, but any other time I get the android with the white triangle screen
Ok, while you are in recovery menu you MUST go down to the Mount and Storage option on the phone and then mount the individual paths because in recovery everything is unmounted except for the cache. Then you type in those commands and you will get the following results..

and as to your second question;
No, it is not normal to have to re-flash your recovery every time after the first use.
Not sure which recovery you are using but it should always be the latest version available.
here is the latest Recovery that can only be used (flashed) if your bootloader is unlocked!

The support is still being worked on, a lot of bugs (I'm assuming) to be worked out. Unfortunately though the manual setup does not work and I have tried every which way possible to get it to work.
Like I said previously, our device is too beastly to be easily tamed
Glad to hear that. Yes we definitally have a beast.

I am, however, going to flash CM7 pre-beta build #3 today and I will try bootmanager app then as the CM7 build has a different set-up as to were things are located (Manual Set-up that is). I will report back if it works
Fingers Crossed!
Unfortunately I am getting no luck with Bootmanager on CM7....
Sorry guys! But stay tuned as I'm sure we will have support very soon!
I was drooling over this app when my buddy with an Inc1 showed it to me. Having it on the atrix would be epic.

Yea I installed it on my boys Evo4g and it is super clean! Though my only issue is that in order to install zips on the ROM's in bootmanager, is that you have to install them through bootmanager and sometimes could cause a boot-loop (soft-brick) so I do recommend, when we get it, to make a habit of doing backups
EDIT: the boot-loop doesn't happen every time, but has happened twice
K, time to give this a proper OP, if anyone wants any of the info that was here before you can look here
_________________________________________________________________________________________________
So, the whole idea here started with me reading an article on how part of the whole I/O problem with the transformer is partially caused by the hardware used as internal storage. I wanted to find out if this had any merit and I figured the best way to do it would be to "replace" the internal storage. I did this by mounting the /data partition to the exteral SD (which according to my research, my specific SD Card is better at writing speeds - allegedly the main problem with the transformer's internal storage hardware wise). Then I ran a bunch of benchmarks and have been running it that way for about 24 hours and so far it feels great. Anyone is welcome to give it a try, and hopefully with help, suggestions and feedback from the community, we can all take as much advantage of this idea as possible.
Before I go any further I want to give credit to those who helped me so far, because without them I would still be completely clueless, and not only have they helped be accomplishing what I got so far, but thanks to them I've also learned a bunch of things I didn't know before. So here it goes:
Rayman - For suggesting the method for mounting /data to the external SD.
lilstevie - For helping me get the new kernel flashed right.
Turge - For showing me how to properly repack the kernel.
Parastie - For suggesting doing the same thing to /cache (working on that now).
dagrim1 - For SQL patch and for suggesting a temporary remount (even though it didn't work it was a good thing to try).
_motley - For all his work on his awesome kernel.
_________________________________________________________________________________________________
Updates:
Update 1 (08-01-2012 File boot-data+cache+internal-AOKP6.1base.zip) :
Now both /data and /cache are moved to the external SD card. This means you need a third partition mmcblk1p3 in order to use this modification.
It will also mount the internal storage (previously inaccessible) to /mnt/sdcard_internal
It also attempts to (fail at this point) to mount the internal sd partition (what used to be /sdcard) to /sdcard/Internal_SD (which is why you will always see that folder get created but stay empty). If anybody knows how to make it work please advise.
Modified Lines:

Update 2 (08-01-2012 About backing up/restoring in recovery) : - READ UPDATE 5
One thing that worried me was that by using this mod people wouldn't be able to backup their data partition properly, but now I know that it's possible to do it. It will only work on TWRP though since it has basic terminal access and keyboard. To do it, go into Advanced > Terminal and in there type:
umount /dev/block/mmcblk0p8
mount /dev/block/mmcblk1p2 /data
And until you reboot, any backup/restore should use the external SD data partition instead of the internal. The same should be doable with the cache partition in case you want to backup/restore that.
Update 3 (08-02-2012 File flashme-kernel-motley305-aokp-data+cache2SD.zip) :
Put together a flashable zip that will install motley's 3.0.5 aokp kernel using this mod. Works like a charm so far though I only tried flashing on TWRP. Also, internal storage can be accessed in /data2 and internal sd can be accessed in /sdcardi . Current changes are as follow:
Code:
# TweakerL MOD > move /data and /cache to external SD card || original mount = mmcblk0p8 /data | mmcblk0p3 /cache
mount ext4 /dev/block/mmcblk1p2 /data wait noatime nodiratime nosuid nodev nodelalloc,errors=panic
mount ext4 /dev/block/mmcblk1p3 /cache wait noatime nodiratime nosuid nodev nodelalloc,errors=panic
# TweakerL MOD > create mount for internal storage
mkdir /data2 0000 system system
mount ext4 /dev/block/mmcblk0p8 /data2 wait noatime nodiratime nosuid nodev nodelalloc,errors=panic
# TweakerL MOD > symlink internal sd to a couple of easily accessible locations
symlink /data2/media /mnt/sdcard_internal
symlink /data2/media /sdcardi
Update 4 (08-03-2012 File boot-cm10-unofficial-data+internal.zip) :
Running the unofficial CM10 (no cherrypicks one) using this mod and so far it's pretty amazing. The rom itself is pretty stable and even snappier with /data mounted to external SD. Benchmarks are at the bottom. Current modifications:
fstab.cardhu:
Code:
#TweakerL MOD > Move /data to external SD and internal /data to /data2
/dev/block/mmcblk1p2 /data ext4 rw,nosuid,nodev,noatime,user_xattr,acl,barrier=1,journal_async_commit,nodelalloc,data=writeback wait
/dev/block/mmcblk0p8 /data2 ext4 rw,nosuid,nodev,noatime,user_xattr,acl,barrier=1,journal_async_commit,nodelalloc,data=writeback wait
init.cardhu.rc:
Code:
# TweakerL MOD > create mount for internal storage
mkdir /data2 0000 system system
mount_all /fstab.cardhu
# TweakerL MOD > symlink internal sd to a couple of easily accessible locations
symlink /data2/media /mnt/sdcard_internal
symlink /data2/media /sdcardi
Update 5 (08-03-2012 About backing up/restoring in recovery) :
So after doing some tests, and paying more attention to TWRP, I noticed something rather useful:
When you have this mod enabled, or whenever you have a mmcblk1p2 partiion, TWRP will have the sd-ext menu enabled. This means that to backup your data you can simply backup the sd-ext partition and to restore your data you can simply restore your sd-ext partition. No need to worry about manually switching the mount point for /data in recovery. I guess it was a whole lot easier than I thought.
Also congratulations and thanks to everyone who has contributed with this so far.
WE MADE IT TO FRONT PAGE ON XDA (08-03-2012)
_________________________________________________________________________________________________
Requirements:
There are a few things you will need to do in order for this to work right for you, and a couple of things you'll have to research before you even try it.
#1. Obviously, you have to be rooted/unlocked because you're not gonna be able to change much around otherwise.
#2. You MUST repartition your external SD. The kernel I've put together so far WILL ONLY mount /data to mmcblk1p2, which basically says "mount /data to the second partition in the external SD." also, the ramdisk expects that partition to be ext4, so essentially:
Make sure you have an external SD with at least two partitions and that the second partition is formatted to ext4. I personally use Gparted to repartition my stuff, but feel free to use whatever rocks your boat. Even if you're on windows you can still use gparted by using virtualbox, so I'm not gonna go look for a different windows solution.
#3. This is the research part... This will be beneficial or detrimental to each user depending on the SD card used. If you have a slow SD card this probably will do you no good. However, just because you have a class 10 SD card, that doesn't mean it will benefit you either. On my own research I have found that some class 6-10 SD Cards have extremely slow random write speeds, so if you happen to have one of those, even if it's a class 10, this might not be for you. This means that you're gonna have to do some research to find out if your SD Card will benefit you or not. You can always just give it a try, as far as I know this is entirely reversible, how easy or hard being just a matter of how bad you mess up on meeting the requirements and following the instructions.
#4. At this point (07-30-2012) I'm doing all this stuff using the AOKP milestone 6.1 kernel as base for my modified kernel, so if you're not using AOKP milestone 6.1, flashing my kernel might borke your system. You've been warned, feel free to proceed otherwise at your own peril.
_____________________________________________________________________________________________________________
Installation:
#1. Download attached file (boot-data2SD-AOKP6.1base.zip) and extract it to the root of your internal storage (/sdcard).
#2. Open a terminal.
#3. Type the following:
Code:
su
dd if=/sdcard/boot.blob of=dev/block/mmcblk0p4 bs=1
#4. Wait for it to complete.
#5. Reboot.
Upon rebooting you will know that it worked because it will look just as if you just flashed a new rom, that is, you'll get the device setup screen (assuming that the tablet booted at all lol). If you're planning to use TB to restore your apps, you'll probably want to copy the TB folder to your external SD's first partition so that you can copy it back once you're done with the device setup (at this point you will have no access - unless you manually mount it - to your internal storage).
_______________________________________________________________________________________
Reverting:
Follow the same exact steps for installation but use boot-default-AOKP6.1.zip instead.
_______________________________________________________________________________________
Optional:
#1. If you want to have access to everything you had on your data partition in the new data partition, you'll have to clone everything from one to the other. To do this, make sure that your new data partition (the one in your external SD) has enough storage space to fit everything you currently have in your data partition (the one in your internal storage). Then run the following command in your terminal.
Code:
dd if=dev/block/mmcblk0p8 of=dev/block/mmcblk1p2 bs=4096 conv=notrunc,noerror
BEWARE that if you have a lot of stuff this can take quite a while and even though I've read a way of getting the progress for this in Linux I'm not sure that you can check the progress on Android.
_______________________________________________________________________________________
Next steps in development:
#1. Move /cache as well.
#2. Find out what happens with recovery backups when the partitions are changed.
#3. Attempt to apply mod to motley's kernel.
#4. Create a script that is run on boot to eliminate need for replacing the kernel.
#5. With help from the community, find the best SD Card for this.
#6. Run the modified system for a while to have a good feel for performance benefits
#7. Come up with other interesting uses for this other than getting better I/O (maybe an easy - kinda easy - way to dual boot with ubuntu, maybe other stuff, dunno).

How can I set my kernel to do this?
I didn't do a whole lot, and it's not like I want it to be a secret, so as I modify things I'll try to keep the steps listed here so that anyone modifying their own kernel who would like to try this modification can go ahead and do it.
You'll need to know how to unpack/repack a kernel. Turge has a SUPER EASY explanation here on how to do it on windows (I'll pack together the necessary binaries for linux later, maybe).
Mount /data to the second partition in your external SD (formatted as ext4 filesystem):
After unpacking the kernel navigate to the folder that has the ramdisk and open it
(DON'T USE ANY ASCII BASED TEXT EDITOR BECAUSE IT WILL PROBABLY MESS THINGS UP I USE NOTEPAD++)
Around line 26 change:
Code:
mount ext4 /dev/block/mmcblk0p8 /data wait noatime nodiratime nosuid nodev nodelalloc,errors=panic
to
Code:
mount ext4 /dev/block/mmcblk1p2 /data wait noatime nodiratime nosuid nodev nodelalloc,errors=panic

/data mounted to mmcblk1p2 (External SD):
RL Benchmark WITHOUT dagrim1's sql patch as per request:
/data mounted to mmcblk0p8 (Internal Storage):
/data mounted to mmcblk1p2 (External SD):
*Important thing to note: When running the benchmark with data in the internal SD it was about 220 seconds in the first run, then about 180, then about 130 and finally 118; whereas running it from the external SD was consistenly between 63 and 65 seconds every time. I think this more than proves that A) Asus used a cheap I/O storage, B) No matter what software changes are made, more than likely running the rw partitions from a better I/O storage, i.e. an external SD is a good idea.
As promised here are benchmarks on a JB rom (Unofficial CM10). Also sorry it took me a while to get these, I was going to use eos3 but I started getting random reboots. Then I decided to try cm10, and I messed up a flash and had to redo a bunch of things. Anyway, the only change here is the mod itself (no custom kernel or anything). Though one thing to note is that I moved /cache back to the internal partition after some thought that this allows /data and /cache to be written at the same time to different locations thus lowering the bottleneck.
/data mounted to mmcblk0p8 (internal storage):
/data mounted to mmcblk1p2 (external storage):
Now, as you can see, JB did bring a major improvement to I/O, bringing the benchmark down from about 115sec to 68 (almost reaching the modded ICS at 60 seconds). But as I expected, better software works better on better hardware and now the modded JB is running at 50 seconds instead of 60. Next I'm going to put dagrim1's sql patch and see how low the benchmark goes. Also will be posting the modded blob in just a little bit for anyone who wants to use it on CM10.
We don't have sd-ext it's an old trick when phones had very little /data partitions, you have the possibility to create a sd-ext partition on an external sdcard and mounting it as a secondary data. (like opt partition on Linux).
To see what block device is data just run 'mount' command in terminal emulator. I don't have my device here.
sdcard cache is already set to 2048 if I'm correct.
Your script would mean creating a sd-ext partition on an external sdcard, modify fstab to have it correctly mounted then applying the script.
Not really easy for common users.
I would rather look at kernel drivers (not I/O schedulers but drivers handling with file system format) but it's quite a hard work.
Hmmm...
Was talking to Rayman and it doesn't actually seem that hard to do... Just gotta change the init.cardhu.rc in the ramdisk to mount /data to /dev/block/mmcblk1p2 instead of /dev/block/mmcblk0p8
The thing is, that while I know every step that I have to take to get it done, I haven't used linux in forever and quite honestly I couldn't even compile blobtools right now if I wanted to to extract the ramdisk from the boot blob to make the necessary change... so yea anyone who knows how to edit a kernel should be able to do it, and then just repack it as a blob... I'll probably look into it later, but if anyone wants to type the terminal commands for to to get/compile blobtools I'll appreciate it...
As in just a mount of data to mmcblk1p2?
Would a temp solution (just to check if it works) be to remount data manually? (Tried it, to mmcblk1p1 btw since 1p2 didn't seem to exist for me, but it still mounts to mmcblk0p8.
Using:
mount -o remount,rw -t ext4 /dev/block/mmcblk1p1 /data
(as su in terminal)

Reason why mmcblk1p2 didn't work is because you have to repartition the sd card to have an ext4 partition... personally what I did was take my 32gb sd card and have the first partition as a fat32 partition for storage and set the rest to an ext4 partition... also, you have to do that because the /data partition is already expected to be an ext4 partition on most of the current ROMs... Trying to set it without doing that most likely won't work.
Also, another thing that's important is that for this to be beneficial you have to have an SD Card with higher random write speed than your internal storage speed... my internal storage speed is about .25 mb/s and my sdcard is about 1.5mb/s so there should be a big difference... Oh and if you happen to have a class 10 sdcard that doesn't necessary mean that it has high random write speed... you actually have to go look up the specs or run benchmarks on it.

Thanks, makes sense yeah... will have to check if it's worth the hassle for now. Not at this moment anyway, but interesting concept...
Stuck... again...
So I figured how to unpack the boot.blob, then unpack the boot.blob.LNX, then decompress the ramdisk... made the necessary change to init.cardhu.rc... compressed the ramdisk to the same format it was before, repacked the boot.blob.LNX, repacked the boot.blob... dd if=blob of=dev/block/mmcblk0p4 seek=28 bs=1 ... and ... nothing... reboot and where you're supposed to get the quick progress bar nothing seems to happen... I'm assuming I messed up on the recompressing ramdisk/packing the boot.blob... but I'm not sure how...
Anyway... I'll post exactly how I did it tomorrow so maybe someone with more experience can help me figure out where I messed up...
But so far, I wanna say thanks to rayman and lilstevie for all the help they've given me so far with this idea.

Just wondering, why did you choose to use seek=28?
I believe the TFP will need the first 28 header signature to be there in order to flash through the staging paritition (p4).
Your other option would be to flash using fastboot:
1. If you've installed the AndroidRoot.mobi bootloader (if you have nvflash), then you can directly flash the boot.blob.LNX file, as this is a raw image.
fastboot -i 0x0b05 flash boot boot.blob.LNX
2. If you don't have AndroidRoot.mobi bootloader, then I suggest you get NVFlash working first and get a backup... if not, you can use the following to flash the blob:
fastboot -i 0x0b05 flash boot blobfileyou'vecreated
3. Use fastboot to flash to the staging partition:
fastboot -i 0x0b05 flash staging blobfileyou'vecreated

I've repacked the boot.img for the Prime before to add init.d support so I'll post my method and the files needed in a few minutes once I get to work. It'll involve getting cygwin installed (with Perl support I believe) if you're on Windows.
Would it be better to move cache and maybe dalvik cache (assuming the SD random read/write is faster then internal memory) ? Since you're only moving data and leaving cache on internal, that'll still hit the issues of having bad IO. Moving cache (which I believe would have more random access) I think would be better.
Thoughts?

Thanks for the idea, I tried to do that but nothing seemed to happen (checking on file manager /data partition is still taking the same amount of space as it did before). It would've been a really good way of testing this whole thing though

I used seek=28 out of despair and by lilstevie's suggestions... dd with or without seek had the same exact result, the staging just ignoring the whole thing lol...
Sounds like a plan (flashing with fastboot)... I've got one dumb question though before I do that (and yea i've got nvflash setup and all the backups and stuff). How do I actually go about restoring the system with NVFLASH if I go and borke the system ? XD

I agree that moving the cache is a good idea, one of the main reasons why I'm testing with /data though is that it will be much easier to have solid evidence of whether this works or not that way since all the benchmark apps seem to benchmark on the /data partition. I know benchmarks aren't real world results, but if I can run benchmarks on the same partition and it's 5 times faster on the SD card than on the internal memory, I think it should mean something. After that, if there are positive results, I'm thinking of moving both /data and /cache partitions and run that way for a while to see how well it performs, and then to run with just the /cache moved and see how that performs.

Here are the steps for repacking the boot.img. Some involve running the commands via cygwin, others involve running them via the Windows Command Prompt.
The instructions for installing cygwin, extracting and repacking the boot.img were found here: http://www.freeyourandroid.com/guide/extract-edit-repack-boot-img-windows
Once you have setup cygwin, extract the attached files in a folder under your "home" folder in cygwin.
copy boot.blob to the same folder and run the following via the Windows Command Prompt to extract the boot.img from the boot.blob:
Code:
BlobUnpack.exe boot.blob
ren boot.blob.LNX boot.img
From the cygwin bash terminal window, switch to the same folder and run the following to extract the ramdisk from the boot.img:
Code:
./extractboot boot.img
You now have an out/ramdisk folder that contains the files you want to edit.
Once done, repack the ramdisk and kernel into boot_new.img with the following command (via cygwin once again):
Code:
./packboot
then from the Command Prompt repack boot_new.img into boot2.blob using the following:
Code:
blobpack -s boot2.blob LNX boot_new.img
You can now flash the boot.blob to the staging partition via a command in updater-script:
Code:
package_extract_file("/boot.blob", "/dev/block/mmcblk0p4");
or by using adb while in recovery/android:
Code:
dd if=/sdcard/boot2.blob of=/dev/block/mmcblk0p4
Did anyone think of running iotop? If we know what part of /data is contributing to the stalls, maybe an interesting idea would be to just mount that part of the tree on SD?
tyvm will get on it now, will report back any results
Sent from my Transformer Prime TF201 using Xparent SkyBlue Tapatalk 2
what's iotop?
Though regardless, the problem I'm trying to deal with is the fact that apparently, the storage hardware in the Prime has limited I/O capabilities, namely random write speeds, regardless of software. Because of this the stalls are at least partially caused by the "where" the /data is rather than the "content" in the /data.

You know, I can just google it, but the fact that you care enough to post your opinion but not enough to explain it is the kind of mentality that keeps people who could potentially contribute to the community from doing so because they have to go research all over the internet, possibly going through bad information, for something that might be very simple. Read a few posts up and you'll see the right kind of mindset. Turge could've just*given some halfassed response and sent me on a wild goose chase but instead he took the time to explain in a way that anyone with any amount of knowledge could understand...
And I hope that since you can't bother to give an useful response, that you can't bother wasting you "precious time" justifying and complaining about how people ask questions that they could just look for elsewhere...
Hi ,
This is new my first post.
I have samsung SGH-i777 initiallly when i bought it has 4.3& it has 16GB card. cyanogenmod10.2 with rooted. but it always restarted because of OOM.
so i installed kitkat 4.4 omnirom and few day it was working good,no problem arise. after week it doesn't show external storage it only show internal storage of 2GB. so again flashed ROM this time with 4.1 & it shows 16GB memory then i could use those space. but problem is if i go to CWM revcovery(i tried latest or old versions) take backup or installing zip got error like this "sdcard can't mount"
kindly help me out of this issue.
Thx
Switching to a different kernel/recovery affects whether the card can be mounted? This sounds like the CWM recovery that you chose doesn't support the filesystem of the Sd Card.
What file system is the SD card using?
For greatest compatibility, I suggest formatting the external Sd Card to Fat32.
If you're going to stay on 4.4, AND if you plan on playing music from the sdcard, I suggest formatting it to exfat (successful workaround for a KK bug).
^^beware, the stock recovery and firmware will NOT be able to read any exfat formatted partition
^^once formatted to ExFat, apps will install to the external SD, but will not survive reboot (keep them on the internal SD)
welcome to XDA,
happy flashing

Hi,
Thanks for your reply.
This is my sdcard partition

The total size of the internal storage of the i777 is 15.8 GB, and it is partitioned as shown in the table below.
From: Settings > Storage, you should see reports for:
- "INTERNAL STORAGE" ~2GB
- "INTERNAL STORAGE" ~11.5GB
- IF you have an SD Card installed, you should see a third report named "SD CARD"
(Using the partition table as reference)
The first "internal storage" is partition #10, or /dev/block/mmcblk0p10
The second "internal storage" is partition #11, or /dev/block/mmcblk0p11
The SD Card is not captured in the partition table below, but if installed, would be found at /dev/block/mmcblk1 or /dev/block/mmcblk1p1
I'm not sure how to interpret your partition report, because it appears that it is reporting the statistics of the internal memory module, and NOT of a particular partition, which is more valuable to us.

@cyril279 you should make reference thread on this subject. I'm going to have to bookmark this in case i need it later. Damn....
So CM 10.2 crashed a lot; Omni drops emmc (embedded multimedia card) after one week; 4.1 works fine until you change CWM recovery, and your partition report seems to be spitting back that your internal storage partition (emmc) is formatted as vfat.
It is entirely possible that your partition-reporter is calling a FAT32 partition VFAT, at which point there's nothing wrong with the partition format, and I have no idea what your i777 is going through. Based on the information provided, It sounds to me as though your internal Sd Card partition is formatted to something that is causing issues running the firmwares and kernels that you have chosen,
If the partition format is indeed the issue, then the solution is to backup the contents of emmc, format mmcblck0p11 to FAT32, and try your favorite firmware/kernel again.
I suggest that you verify the file system of the internal sdcard, using a different means than you have been.
The difference in FAT and FAT32 is well documented, but I am unclear on the importance of the differences in between VFAT and FAT32. A quick google session has lead me to understand that they are NOT the same, but quite a few threads in various forums seem to refer to them interchangeably.
Maybe I'm completely on the wrong path here, I welcome any input.

No, you're on your OWN path. That was great, razen's right: you should consider creating a reference guide and we could get it stickied. As new users come in (which amazes me, due to the age of our device), it would be a wonderful asset to have a reference written by someone who understands this.

...That's the part that concerns me, I'm not totally convinced that this issue should have lead me in this direction, but the only time I've ever had an issue with firmware recognizing the SD Card was when I started playing around with formatting partitions, so it seemed reasonable. Looking back, the original post points several directions all at once, and without a more systematic approach (like installing the firmware clean, then installing one app at a time, NOT from TiBu backup) we won't know what the real issue(s) is/are/were.

These handsets are old, but when my wife and I finally decided that we wanted smart-phones, the i777 met the criteria of inexpensive, well-rated, dual-core, and well-supported, Android devices. Regarding a reference post, I managed to cobble-together a rough understanding from guides for other devices, but my understanding on the partition madness still isn't the strongest. Either way, I certainly don't mind compiling what I've found into something concise and specific to the i777.
harmonica.ss, are you still there? don't give up on me just yet.
I did finally get a chance to check the "mount" stats of my wife's i777, which also reports the user-storage partition as vfat. Her i777 has spent significant time on SHostock3, cm 10.1.3, & Omni 4.4; all without internal storage issues.

What kernel, and what firmware are you using? <-- this should have been my first question.
from my wife's i777:
Code:
/dev/block/vold/259:3 /mnt/media_rw/sdcard0 vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1023,gid=1023,fmask=0007,dmask=0007,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
/dev/block/vold/259:3 /mnt/secure/asec vfat rw,dirsync,nosuid,nodev,noexec,relatime,uid=1023,gid=1023,fmask=0007,dmask=0007,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

How do I partition the sd card? I kind of got myself into a rut and then after the fact finding out that I needed to partition the sd card. Maybe you can help? I can send you a message of what I did. It's kind of a long message.

This is the forum that I had followed. http://forum.xda-developers.com/gal...ta-storage-t2839161/post54633983#post54633983
1. Went into download mode using usb jig
2. Odin on PC. I777UCMD8_I777ATTMD8_I777UCMD8_HOME.tar.md5 in "PDA SLOT" flashed
3. Phone boots up went through all set up.
4. Enabled USB debugging, checked allow install on unknown resources.
5. Installed "framaroot v.1.4.1 Root - Installed Odin Mobile – Reboot - flashed (zImage) jeboo_kernel_i777_v2-3a through Mobile Odin.
6. Boot into download mode.
8. Odin on PC - i777_4GB data - 45mb preload - 1GB system_pit in "PIT SLOT". I did not uncheck the reboot. Phone rebooted.
9. When it powered on, I would see the AT&T and then it would blink in and out and then it looked like it was shut off but it wasn’t.
I am able to go into download and recovery mode.
When I go into the recovery mode this is what it says. I have attached the picture.
In that forum step 10 says if internal cannot format then ......... Well I'm unable to mount storage or I just don't know how to.
Well after all of that the other day I thought I well maybe I can just flash back to stock tried that didn't work.
After 12 hours of trying to research I finally gave in to ask.
Are you able to help?
OMG!! The excitement is for real! I flashed back to SGH-I777_UCLE5 and now the phone actually boots up!! Thank you for your help!

So I'm trying to partition my I777 for more storage. I've been trying to follow this post - http://forum.xda-developers.com/gal...ta-storage-t2839161/post54633983#post54633983 .
I'm having a bit of issues with Post #10. 10. If internal cannot format or gives error, connect phone to pc and mount storage, you can then format as fat32 from windows or whatever operating system you are using (recommended system). When done, unmount and try step above again just to be certain.
I connect my phone to PC and I'm unsure how to mount the storage and format to fat32. I click onto the Samsung phone, then it shows the external sd card and the phone. I have right clicked on the phone and scrolled to format but it doesn't specifically state it formats to fat 32.
Can you try to help me again?

Oh my, what a journey you've had in the last few days, I'm glad to hear that you got the initial problem sorted.
It has been some time since I messed with formatting the internal storage partition, so I would have to re-familiarize myself with the process before issuing further advice, and I don't have as much time as I once did (I have two young children now) but I will look into it. My responses will not likely be swift.
Have you read over the partition/formatting guide?

Does the phone internal storage partition remain the same or has been successfully partitioned as per the guide?
Hi there, first time I write here and I probably have a lot to learn
However, a few days ago I accidently dropped by Galaxu SIII from my balcony. As a result both the screen and the touch is broken, the rest seems to work. So, of course I can connect the phone to my computer and gain access to those folders that are always monuted. However I wan't to get access to all files, like I did on the phone after I rooted it. It looks like USB debugging is off even though I was sure it was on, ADB refuses to see the phone anyway. I have tried many ideas, including remote connection to the phone, but all soloutions require to either enable USB debugging or open an app and that is exactly what I cannot do! So what can I do besides getting a new screen, which I don't want since I've already brought a new phone. Mostly I want to save my contacts and I cannot to that with Samsung KIES since I have CM11 on the phone. I really can't find any solution and I really hope somebody out there can help me!

I suppose your files are not on the SD-Card? If they are just remove the card, but I'm pretty sure you wouldn't ask this question if it was that easy!!

You could try nandroid backup from recovery, maybe using an otg for watching what your're doing on a separate screen.
When all data is nandroided, you can try going trough the backup (the data section specially).
If the backup has several parts (ie, a b c d… ) you can "merge" them into a single file that could be opened with 7zip or winrar. Just open a DOS command prompt and:
type data.ext4.tar.a data.ext4.tar.b >> data.ext4.tar
Thats the example for 2 parts a and b.Then, after unpacking the tar, you could look into the data to get stuff. For example…
Sms & mms:
data/data/com.android.providers.telephony/databases
Contacts:
data/data/com.android.providers.contacts/databases
And a lot of other stuff. Note that you need something to read-edit ".db" files, like an sqlite editor.
Alternatively, if you're using a similar phone, with same manufacturer, a close android version (for example not gb 2.3 vs kk 4.4, but yes jb 4.1 vs jb 4.3), etc, then you could copy such addresses and paste them inside your new phone (crossing fingers and any other crossable bodypart) and you might get all that stuff back.
Good luck.
Put a blank SD (formatted as FAT32 or exFat) on the phone. It must be sized as the phone's internal memory size (16 or 32GB)
Set the phone in download mode. Flash Phil'z recovery with Odin.
Start the phone in recovery mode. Connect usb to computer and after 10-15 seconds ADB will be enabled.
/data is mounted by default (internal SD is stored inside /data).
Now mount the external SD:
enter adb shell and put:
Code:
mount /dev/block/mmcblk1p1 /external_sd
If any error appear, stop.
If nothing appeared, check that it was sucessfully mounted. Ensure that mmcblk0p12 and mmcblk1p1 are mounted as this!
Code:
mount
rootfs on / type rootfs (rw)
tmpfs on /dev type tmpfs (rw,nosuid,relatime,mode=755)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
proc on /proc type proc (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
/dev/block/mmcblk0p8 on /cache type ext4 (rw,nodev,noatime,nodiratime,barrier=1,data=ordered)
/dev/block/mmcblk0p12 on /data type ext4 (rw,nodev,noatime,nodiratime,barrier=1,data=ordered)
/dev/block/mmcblk1p1 on /external_sd type exfat (rw,relatime,fmask=0000,dmask=0000,allow_utime=0022,codepage=cp437,iocharset=utf8,namecase=0,errors=remount-ro)
Now copy all the internal storage to the external SD:
Code:
mkdir /external_sd/intData; cd /data; tar cf - * | ( cd /external_sd/intData; tar xf -)
Take a breath and come 15 minutes later to see if it finished. It may take more if the device was nearly full.
After it comes back to shell (you see the # symbol again) it means it's over.
Now let's flush the filesystems and unmount the partitions :
Code:
cd /; sync; umount /external_sd; umount /data
Remove the battery and the sd card.
Put the SD on your computer...done!
- The internal SD is stored on /data/media.
- The app data is on /data/data.
- The apps are on /data/app
- Your contacts are stored on /data/data/databases/com.android.providers.contacts/contacts2.db.
Putting that DB file on the same place of other Android phone and rebooting after will restore your contacts. Or you can convert them to VCF:

Amazing answer, however during the first steps, could he be blocked? Due to not seeing the screen? Maybe I'm over complicating things.
