im working on building a cm7 kernel for the vibrant, but im having some trouble
i have th compiled zImage but new a ramdisk and recovery img to compile with the zImage into a boot.img
i know im supposed to sync the cm repo, but kernel.org is down and the with the roundabout way im literally getting 5kib/s max and even after leaving my computer on for like a day im not close to finishing the download
so my question is, can anyone instruct me on how to extract the recovery and ramdisk from the boot.img and then how to repack it or can someone upload it and tell me how to repack it?
thanks

Hi there guys,
I am having an issue and was wondering if someone could point me in the right direction, maybe to a tutorial or some decent info on this.
Anyways, I have been tinkering around and teaching myself about building kernels, and roms and just a short while ago finished compiling my first kernel. I have the zImage, and i have tried adding the zImage to Koush's AnyKernel updater.zip but when i try and flash it says failed but is not displaying any errors (Using TWRP recovery) Or I am doing this wrong and need to unpack and repack boot.img with the new zImage?
Any help is greatly appreciated, Thanks!:good:
(edit) I am building on Fedora 17
You answered your own question.
Unpack the boty.img and repack with new zImage
So I was in the right ball park at least.

Will fastboot boot boot.img work on the galaxy note for testing a kernel? In case I have a borked kernel I want to take precautions so I don't brick my device.

No to fastboot.
With a broken kernel you should still be able to button combo into recovery and just flash a working kernel .zip
Or..at the very least be able to boot download mode and use Odin to flash the kernel.
I have gotten the boot.IMG all packed back up and when I flash it, my phone just hangs up at the white Samsung logo screen and does not go any further. Does something in the ramdisk have to be edited?

Hello,
since I don't yet have access for the specific section I post here
I can't find how to flash a kernel built from source (aka zImage). Since fastboot is not available on GS3, I just want an alternative tech to boot my gs3 with my build zImage.
I build the source from stock kernel samsung opensource database (update 8) and receive a zImage file.
I made a backup with cwm and unpack the boot.img with a perl script, then repack a new boot.img with my zImage as kernel and the ramdick from unpack but cannot boot with new package.
Could someone maybe give me a kernel source and the right corresponding package to boot it. Or maybe just a good way to make the whole process.
My final goal is to build a custom module for the GS3, that's my I need building from source and not an already-packed-kernel. Moreover if someone can help me directly about the module, he's very welcome
Hi,
I don't try to flood, just to increase my chance to have any help
I want to build a custom module for my GTi9300. Since the module need to be compiled whith the same kernel on the phone, i tried to build and flash a kernel from source (aka zImage). Since fastboot is not available on GS3, I just want an alternative tech to boot my gs3 with my built zImage.

Without having the same kernel on the phone, I already tried to insmod my module. I've got first some version error, with the module_layout. Even if I correct it the module still doesn't load. In the kernel source, I modify the Subversion in the kernel to match with the one on the phone. But the compilation result add a "-gc33f1bc-dirty" to the end. Maybe I miss something to do before the compilation
Please post all questions in the Q&A section.

Dear xda-developers members,
I need some help in the right direction:
I have installed Dhollmen's kernel (from forum.xda-developers.com/showthread.php?t=2176563) on my GT-P5110
which is rooted and running CM10.1 at the moment and I used cwm to flash the kernel (from the link above).
Now I am trying to compile the kernel from their source code (see link) and flash the compiled kernel.
This has not been a success yet. I either get stuck at bootscreen or in a boot loop.
What I have tried:
Code:
export ARCH=arm
export CROSS_COMPILE=~/android/toolchains/arm-eabi-4.4.3/bin/arm-eabi-
make dhollmen_P51XX_defconfig
make
This resulted in zImage file and I tried to flash with heimdall:
Code:
heimdall flash --KERNEL arch/arm/boot/zImage
This got me stuck on the bootscreen
Try 2:
With the compiled zImage and the working Dhollmen kernel zip (DhollmenCM-P51xx-Kernel_20130706.zip from the link)
I unpacked the working Dhollmen kernel, split boot.img, replace zImage with mine, repack to boot.img, repack to zip and flash zip from cmw
This got me stuck in a boot loop
The frustrating thing is that I have no errors so I am clueless of what is going wrong.
Can someone explain how he is going from his source code (https://github.com/Dhollmen/DhollmenCM_kernel) to a flashable zip file?

Hi everyone,
I need some help while I try to compile my first kernel (for experiments) with the Linaro-Toolchain. I followed a youtube instruction and it works well till the point to handle a stock/original boot.img file (with $ abootimg -x boot.img)
INFO: I´m playing with the slimkernel source, Linaro toolchain and mint 17.
Well before bothering you, i tried 1000 different ways to get this boot.img. But:
- extracted stock fimware only contains a boot.bin (and size does not match)
- a boot.img form a custom kernel zip brings me "no Android Magic value. giving up"
- downloadable boot.img are for all other phones excluding i9100...
Do you have any idea how to get this f****g boot.img which is working to get the kernel compiled, or do you know what i did wrong with that??
Thanks in advance
Ambador
Have you tried to extract a boot.img from a slimrom zip?
Yes I did but gave me the same result. I tried different kernels, roms and everytime while typing abootimg x -boot.img the fail appears.

I don't know really what you are doing atm because you are compiling a kernel from the kernel sourcecode. But I think that you are going to replace the zImage in the boot.img because kernel compiling doesn't include ramdisk right? Did you ever tryed to use dsixda-kitchen, It's usefull and also easy to use with kernel extracting.
Sorry if I got you wrong.
I used that kitchen already, but gave me the same missing android magic issue.
I tried an other thing, cuz im currently using apolo 7.1 kernel:
this kernel has a zimage only. So is it a possible way to get the kernel source, make a change (add an scheduler which is not in kernel) to see if it will work, compile the zimage with linaro and just replace it in the kernel.zip??
