hello every one,
is there any body who can help me with my problem Pleaaaaaaaaaaase ?
I rebuilt the GT-I9100G_ICS_Opensource_Update2 kernel, ang i get my Zimage, but when flashing it in to my I9100G phone i got a boot issue (KERNEL CANT BOOT stock into boot image) ,
for information: i am using :
- Ubuntu 11.04,
-i tried the "arm-2010q1" toolchains and the "arm-eabi-4.4.3" one ,
- am using initramfs of Mr superatmos, that he mentioned in his thread http://forum.xda-developers.com/showthread.php?t=1587482 .
- i am working with "android_t1_omap4430_r03_user_defconfig", imade no changes to the .config file just the CONFIG_INITRAMFS_SOURCE.
my phone is on the ICS 4.0.3 ROM, with the 3.0.8-TH [email protected] #1 kernel version
An other question: what's about the LOCALVERSION parameter ? it could be the problem ?, How i can get Kernel Logs when it is booting ??
i am working over 12 days for now, searching and testing with no result

Hello,
Been wrestling some time with different firmwares / mods and kernels. I had many problems and currently re-visiting my 900 apps long list in Google Play.
Currently I'm very happy with [ROM] Android Revolution HD 17.1 | High Quality & Performance | AROMA | Android 4.1.2 - especially after the many problems I had with my previous Franco kernel
BUT, again, I've chosen a custom kernel, advised by Revolution HD: Perseus-alpha27.1-i9300.tar . This kernel (?) seems to have very bad wifi performance. And I mean really really really bad Upgrading to Perseus-alpha29.1-i9300.tar did not fix, although Change Log mentioned improved wifi performance.
After having spend changing kernels and stuff many times with Odin 3.04 (I still don't understand how it knows WHAT to flash when 'an image' is offered... Must be in the tar itself, but still I thought I could easily download the Samsung Galaxy Siii official stock kernel (NOT ROM, but KERNEL). Should be a small file (<10MB), not a >700MB download with the ROM included.
I've browsed many threads on xda and beyond, but downloading JUST the OFFICIAL kernel... SIGH I cannot find it?!!
What am I missing here??
Very curious if anyone can point me to a download link for the official kernel.tar I need? Or kernel.zip? I don't feel like re-installing everything, I just want to re-install the kernel alone. OR is this impossible? Please advise, I don't like feeling like a newbie
One of the few downloads I could find (like forums . androidcentral . com /verizon-galaxy-s-iii-rooting-roms-hacks/191375-guide-restore-back-clean-factory-stock-update-10-23-a.html) do not work - when flashed my phone ends up bricked (tested many times:0).
Anyway, thank you for a great forum!
Phone info: Samsung Galaxy Siii International GT-i9300
Android Version: 4.1.2
Baseband: i9300xxelkc

See your other post I have replied to that one.

Trying to solve it myself - part xxx ;p
The following Google search brought some light to the end of the tunnel, I hope: http://www.google.com/search?q=stock+zimage+i9300+samsung&oq=stock+zimage+i9300+samsung&ie=UTF-8 .
It first brought me to this page: http://androidromupdate.com/2012/06/05/how-to-install-stock-rom-on-samsung-galaxy-s3-s-iii-gt-i9300/ .
There I learned the following (quote):
" Stock ROMs contains the binary and image files of the whole software packaged, like these:
* Sbl.bin
* cache.img
* factoryfs.img
* hidden.img
* modem.bin
* param.lfs
* zImage "
So I figured to let 7zip extract the stock firmware I downloaded (>700MB). Except for unexpected archive header warning, 7zip extracted just fine. I ended up with:
* boot.img
* cache.img
* hidden.img
* modem.img
* recovery.img
* system.img
From the chapter "For some reasons how to root the device info is here" (http://forum.gsmhosting.com/vbb/f200/galaxy-s3-i9300-flashing-root-guide-1483155/), I learned the following:
Quote: " According to Chainfire, the modification of the kernel was not as easy as done for the SGS I, SGS II, and SG Note, because, “…this time around, Samsung is using the standard boot.img format, instead of the zImage format used for SGS1, SGS2, SGNote, etc, that is much harder to repackage.”
This time around, the SGS III also has a separate Recovery partition, and unlike its predecessors, a custom recovery can now be flashed independent of the kernel."
So zImage is boot.img on i9300 - finally I learn something :> Also see: http://forum.xda-developers.com/showthread.php?t=2022181 .
I was hoping that I could just flash this file with Odin. I have not tried it yet, for I first wanted to make sure that boot.img === kernel-to-flash
http://www.google.com/search?q=what+is+a+zimage brought me to http://www.embeddedarm.com/support/faqs.php?item=2 and especially http://forum.xda-developers.com/showthread.php?t=1284986 . And brought many more questions - just flashing does not seem to be the trick?
So googling some more:
http://www.google.nl/search?q=is+the+(zimage.img+OR+boot.img)+the+same+as+the+kernel??&ie=UTF-8 brought me to: http://forum.xda-developers.com/showthread.php?t=1477845 where there are instructions on how to split the kernel :s SIGH - why is this so hard??? Grmbl.
Quote: " At this point, we need a boot.img file to play with.
Pick your favorite custom kernel and get the .img.
Place it in a folder along with the 2 perl scripts from the attached package.At this point, we need a boot.img file to play with.
Pick your favorite custom kernel and get the .img.
Place it in a folder along with the 2 perl scripts from the attached package. "
And: " Can I do this on Windows? - Not that I know of, no. " SIGH!!
At this point, I'm about to give up again. One more page? http://www.freeyourandroid.com/guide/extract-edit-repack-boot-img-windows .
Quote: " boot.img is a small(ish) file that contains 2 main parts, the kernel (the brain of the Android system) and the ramdisk (a core set of instructions and binaries that begins the boot process and controls base aspects of the system, such as mountpoints, memory management and startup services). "
This looks promising! This solution works on Windows by installing Cygwin (Linux for Windows) and the for-mentioned scripts. I learned more AND I see confirmation for what I already learned...
Quote: " boot.img-kernel is the compiled kernel blob that was inside the source boot.img, if you want to replace the kernel with another compiled kernel image, you can replace this file with another one (but leave the file name the same)
boot.img-ramdisk.gz is the gzipped ramdisk image which has been split from the boot.img, you should leave this file alone.
The “out” folder contains the EXTRACTED ramdisk, and this is where you should make your changes to the ramdisk. "
This is something I definitely will try out tonight when I'm home - light again?
Peace!

Some further technical info and background reading with some nice tools: http://android-dls.com/wiki/index.php?title=HOWTO:_Unpack,_Edit,_and_Re-Pack_Boot_Images (from: http://forum.xda-developers.com/showthread.php?t=1831027 ).
Partial solution for my stalled wifi connection due to custom kernel (gs3)
I'll will investigate the splitting-process one day for sure. For now, I have solved it, although I expect problems...
To manage the phone, I downloaded SGS3_International_ToolKit_v6.0.exe (>100MB). After installation this gives C:\Samsung Galaxy S3 ToolKit\root . This folder contains many boot images (stock or insecure). I chose for boot-insecure-xxdlj4-i9300.tar (for Android 4.1.1).
After flashing it with Odin, my wifi problems with slow to stalled network traffic was instantly solved Now my phone reads as follows:
GT-i9300 / 4.1.2 / i9300XXELKC / 3.0.31-368423 [email protected] #1 SMP PREEMPT Fri Oct 19 18:17:48 KST 2012 / Android Revolution HD 17.1 by mike1986.
LAST QUESTION, for now, is: is it pure luck that the kernel made for 4.1.1 works with 4.1.2? Or does that have nothing to do with it???
Peace!

Actually the new boot.img is a lot easier to decompile and recompile compared to the SGS1/2's zImage format

I can provide the boot.img from xxelkc
Actually I use franco.kernel updater app in which I can either backup or restore my kernel
That's how I got the boot.img

Yeah, that's how all my troubles started I first did Franco kernel, then I switched to ClockworkMOD. I had problems and wanted to reverse kernel with the backup I made with Franco Kernel Updater app. It failed and gave me bricked phone
I really start to think all those custom kernels are to be AVOIDED ;p
Thank you, merry christmas and... Peace!

Hi Every body ,
i want to flash a modified kernel in to my I 9100G phone , and am wondering is there any body could help me
by sharing a download link of the AnyKernel.zip tool
Ps: i want to flash my ZImage and the ramdisk with the built modules .
best regards
Hey.
I hope you know, what you are doing anyway https://github.com/koush/AnyKernel this is what you are asking just download zip.
Oh and you can give me a shout if something goes wrong
Thank you for your Help , i will try flash the kernel today,
adding information that, am trying to build the "GT-I9100G_ICS_Opensource_Update2", and i choose this tool to help me flashing my Zimage with the ramdisk (initramfs) including the Built modules .
Thak you, i will give you shouts
hi,
thanks to Mantulis for sharing the link .
After downloading AnyKernel.zip , i did the necessary steps by moving my zImage to "kernel folder" and the built modules in "/system/lib/modules/" folder , but it seems that i couldn't flash it using the CWM ,
i had the message like :
finding update package ...
Opening update packages ...
Installing update ...
AnyKernel Updater by Koush
Extracting system files ...
.
.
.
Done ...
but when viewing my Kernel version i found that it's the same old on (the kernel didn't flashed for real !!!!)
Ps:
I rebuilt the GT-I9100G_ICS_Opensource_Update2 kernel, and i get my Zimage,
i am using :
- Ubuntu 11.04,
-i tried the "arm-2010q1" toolchains and the "arm-eabi-4.4.3" one ,
- am using initramfs of Mr superatmos, that he mentioned in his thread http://forum.xda-developers.com/show....php?t=1587482 .
- i am working with "android_t1_omap4430_r03_user_defconfig", imade no changes to the .config file just the CONFIG_INITRAMFS_SOURCE.
my phone is on the ICS 4.0.3 ROM, with the 3.0.8-TH [email protected] #1 kernel version
Hi people,
after downloading AnyKernel.zip, and flashing the .zip to my I9100G phone, i always got a boot loop,
After the researches that i made, i understand that the Anykernel.zip was developed to HTC smartphone and not for te I9100G,
i Solved the boot loop situation by getting a new initramfs from the CWM kernel source and compiling my zImage with the arm-2010q1 toolchains.
Salutations.
I downloaded the zip and flashed it...
Still in a boot loop. Could more light be shed on this operation. Thank you.
Hello,
I have a GT-i9100 4.1.2 XWLSD, I downloaded GT-I9100_JB_Opensource.zip, I built the Kernel Image following the instuctions of README_Kernel. I used u1_defconfig and arm-eabi-4.4.3 then I flashed the new Kernel without any modifications to my device and all worked perfectly, except TOUCH KEYS(MENU & BACK) and the backlight too.
I dialed *#2663# in my phone and I could see TOuch key fW 0x00 I tried to update it but it failed.
Would you mind giving me your suggestions?
Best regards

From where did you download the file? Sorry I cannot help you I have never modified kernels in my life always seemed too risky to me maybe others here will help you , but I wonder why build a kernel when several more experienced people have already done it for you, why don't you just flash something like Philz kernel.

I've downloaded the file from open source samsung page but I didn't modify the Kernel I used de default config my intention is only try to compile the default kernel to experiment with it.
Solved!! I managed to get it work, the sources from "GT-I9100_JB_Opensource.zip" does not include Cypress touch key driver wich is located in "Kernel/Drivers/Input/Keyboard/Drivers". I copied it from Jeboo Kernel sources and I modified it KConig and Makefile to compile them.
Finally I got a Kernel with PL2303 serial usb converter working on my galaxy S2 and the touch key works too!!!
Hey Guys,
I'm following sony tutorial on how to build stock kernel.
It is my first time doing something like that so I don't have a lot of knowlodge.
I done the following.
- Downloaded the source
- Downloaded prebuild toolchain by doomlord
- configured the kernel
- edited menu config and got zimage
Then I'm stuck , don't know what to do next...
So my questions is :
1- from where should I get stock ics ramdisk ?
2- How can I merge the ramdisk and zimage to get my boot.img ( I mean finishing compiling process ) ?
Other questions
1- Do I need to edit menu config only to get ext support? ( I used "ncurses-devel" which enables me to edit menu config via terminal , and I think I found ext2/3 is enabled by default if I'm not mistaken!!!! )
2- How to upstream the kernel to the latest available ?
3- how to add a patch ( like power button + home key = fast reboot )
I just want to create a simple kernel close to sony's one with tiny modifications , and have some fun by compiling too
I'm using ubuntu for this...
If anyone could help by answering my questions or pointing me to the right tutorial , I'll be thankfull.

1.you can get ics ramdisk from ics stock kernel.
2.get kernel kitchen
1.1you need to edit ramdisk to add suport
1.2you need to find your way to upstream it.
1.3its not posibole to go to fast boot with that module coz semc bootloder use menu bootn.that conbinacion is used on samsung phones.

1. Is this the right way to get the ramdisk from 2011 xperia stock kernel
Edit: used kernel kitchen for this
2. I have kernel kitchen Should I use it to assemble boot.img ?
Also in sony tut. they used mkbootimg program
Edit: will figure it out myself insted of looking dumb xD
1.1 ok
1.2 still searching but do not know how!
need help
1.3 I didn't mean fastboot I meant device reset Home + power key , already there in some xperia 2011 stock based and JB kernels.
Thanks for answering my questions , I'm noob trying to learn here

look at naa kernel,its for reset keyboard...look at his source its inside kernel
ok will check that...
another thing
Can I take cwm recovery from other custom kernel and simply put it in my ramdisk sbin folder or it needs modifications?
Compiled successfully
Kernel Compiled successfully, and I flashed it to my phone. booted fine
But now I've a problems:
- A message shows "are you sure you enabled root"
I already changed ro.secure=1 to =0 in defualt.prop in ramdisk
anything else to do?
Hi guys, I'm doing a Cyanogenmod 12.1 porting for my device that is unsupported. I can build everything and I get a flashable zip but I'm using a prebuilt stock kernel image extracted from the stock lollipop rom. After flashing, the phone does not boot and It's impossible even to access to logcat, so I think it's a kernel related issue. My question is:
- I have the stock kernel source (v.3.10) given by the vendor
- I have the cyanogenmod kernel source (v.2.69)
Do I have to build the stock kernel or I can build the cyanogenmod one by merging the drivers modules and others stuff?
And if I flash a wrong kernel image can my device become unusable?
I read that is not fair importing built kernel modules from other kernel version, but if I merge the kernel trees, is it the same?
Sorry in advance if my question is a noob question
Well I don't know much about porting roms or kernels though. But with what I've heard flashing the wrong kernels can permanently render your phone useless..
