I know this is a bit scarce, but I need help with a kernel. Why? Because I unfortunately don't have a
computer at the moment (much less Ubuntu suite), just my trusty GT-i9505. Also, I have a few
questions.
First of all, this is the guide I am following:
[GUIDE] Use aircrack-ng on android phone using Wireless USB Adapter
http://forum.xda-developers.com/showthread.php?t=2338179
This guide is aimed towards amateur kernel builders,
and the suggested ROM for use with this is Cyanogen Mod. Although, the post does mention that he was able to use his stock touchwiz ROM. He mentions he was able to do it with a few minor adjustments (along with the kernel and .md5 file):
I got this to work on my stock Samsung TouchWiz ROM by making a few adjustments:
- Get the kernel from Samsung: http://opensource.samsung.com/
- Change the lines in the .config file of the kernel below ## Samsung Rooting ... from =y to =n using nano
- To get boot.img, download the ...tar.md5 firmware matching your current firmware from http://www.sammobile.com/firmware/, rename .tar.md5 to .tar, and extract the boot.img. You cannot use mkbootimg here, only abootimg, as this boot.img has a special ramdisk address!

I would love to do this with my current TouchWiz ROM, (not stock) Samy Deluxe ROM- Operation Ivy
Any help/luck doing this? Thanks in advance
Bump
Bump. Let me also add that I can give the source to the kernel (of the ROM I have).
Really all that needs to be done is to rebuild that kernel (and follow the steps of course to the guide I'm using).
I have a TP Link tl-wn722n USB Wireless adapter, so I need to have the module/driver installed into that kernel.
The name of the kernel is 3.4.100-GoogyMax3_TW-v1.1.3
Here's the link to the kernel: http://forum.xda-developers.com/attachment.php?attachmentid=2895862&d=1407942420
I downloaded my kernel and looked inside of the zip file and don't seem to find a ".config" file as mentioned in the guide, but did see a boot.img so I don't believe there's a need to download the .md5 file:

ok heres my problem so far. i know howto compile kernel from source, and i've manage to compile one for my live walkman, but what i dont know is howto repack the compiled zImage with ramdisk?
on my previous device samsung galaxy ace i can use a perl script from here to repack and i know that the base parameter is 0x13600000 and pagesize is 4096.
so my question is:
1- is there any similar script that i can use te repack kernel for sony?
2- if theres none, can i use the said perl script by modifying base parameter and pagesize specifically for live walkman?
3- for live walkman, what is its kernel base parameter and pagesize?
4- i know that all of our current custom kernel had cwm recovery repacked as one with the kernel, and my guess is its in the ramdisk. so which file is the cwm recovery in the ramdisk?
thanks before
ummm anyone?
i cant give u any other help rather than this
"bump"
you can sms to Doomlord for helps, he's so kind
damn... still cant figure out why my kernel wont boot.
i'm following this thread to repack the ramdisk
http://forum.xda-developers.com/showthread.php?t=1477845
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!

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.
Anyone here can u tell me how to create source code of a new device as my device is INFOCUS M680, kernel source.
I have used another device as same board to create source of my device but the kernel source is different. So anyone can tell me how to create kernel source and device tree.
My kernel version is 3.18.19+
Find the open sources for your device and download them. You need to match the build number from that release to the build number for the AOSP sources and download those as well. I have only done Samsung so far but the instructions are fairly clear for merging the sources. Next you need hardware drivers, in my case I have tons of free drive space so I just copied the entire /etc and /vendor from my device firmware.
A lot of time can be saved by downloading a matching sources from a custom rom. You can take configuration files and etc.
No open sources and no custom roms? You should start on something easier my friend. But if you want to continue forward with that I am guessing here. Unpack the boot.img and recovery.img files with the available unpackers. (save the info for the images and follow how to repack carefully) Match your build number to the AOSP sources and get the kernel. Modify, hack, gather and assemble what you need to make a new boot.img and recovery.img. Then with great courage comes lots of bricked devices..
Late reply so I didn't try to hard there. I will always help people send me a PM if your stuck

Thanks for your reply.
I am planning to create a custom rom for my samsung tab A Sm-P555
Where do I start ? Is there AOSP for it ? How do I unpack everything ? Could you help me as I was very new to this ?
Many thanks in advance.

Hola
Perdón pero estoy sufriendo errores con la app XDA labs
Thank you
Hello,
First of all, this is my first post in the forum and my first time trying to compile an Android kernel.
My intention was to port Nethunter for my tablet, Samsung SM-T580 (Galaxy Tab A6 10.1 only wifi).
I have successfully compiled the original kernel offered by samsung and i have ended up with a file called Image, a file called Image.gz and a dts folder
I have extracted the original rom boot.img with mkbootimg_tools and i see a kernel file, a ramdisk folder, a ramdisk.packed file and a dt.img
For what i have found is that this must be a non standard thing, the way samsung manages this, and despite i have seen various guides on compiling samsung kernels, i haven't found anyone doing it straight from samsung sources.
I think that the dt.img part is solved with the dtbTool, but i haven't been able to figure out what to do with Image and Image.gz to get the kernel and ramdisk.
¿Can someone give me a lead on this? ¿Is it doable? ¿Should i look for other kernel instead?
Its been long time ago... But did you manage to compile the kernel?
