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

I wanted the stock kernel because of battery drain issues present in many custom kernels, mine included, because although I used the semc sources to compile my kernel, it still had worse battery drain than stock.
I have unpacked the zImage from the kernel.sin in the 4.0.2.A.0.42 and then made that and a modified ramdisk into a boot.img, which you can flash.
This is for people who want to stay with the stock kernel, but want clockworkmod recovery.
Kernel string version:
Code:
2.6.32.9-perf

MD5: 1ad7e6db6258b73555f0e6ae73fe4fd6
To flash, use the command:
Code:
fastboot flash boot boot.img
If you are on linux:
Code:
./fastboot -i 0x0fce flash boot boot.img
Don't forget to say thanks if you use this!
Yo installed it the custom recovery works fine and now testing UPDATE-looks like its not starting up for me ill try a reflash UPDATE-its not working properly the system wont start man
Super interested in this since I went back to Stock rom moments ago so I can play FIFA 12. Will this work with the new HK 4.0.2.A.0.58 rom released as I have just put that on.

Yes, .42 and .58 use the same kernel.
Will this provide root? I only install Doom's for root & recovery, so if this does I'll use this instead. Thanks.

No root, but you can flash RootXperia.zip in clockworkmod (search it on google: rootxperia.zip).
Done but having booted after installing and rebooted into recovery (which worked) then restarted to phone it wont boot. Black screen after Sony Logo.
Update: Boots after 15 minutes no battery but now android market is keep coming up unsuccessful
Update 2: It just will not boot so I had no choice but to flashtool 4.0.2.a.0.58 back to default. :-(

Actually had market problems myself too, it is very wierd :/
Doesn't work at all for me - fastbooted it left it for a bit
came back and got the red blinking light.
What is the trick to get a stock kernel.sin to a working boot.img ? (Spent most of this afternoon failing to get it to work). All I really want is ro.secure=0 (or ro.debuggable=1). fastbooting CWM is ok for me.

Small how-to for creating insecure kernel
1) Unpack kernel.sin to get zImage and ramdisk (tools posted in my other thread)
2) unpack ramdisk
3) edit default.prop and set ro.secure=0 & ro.debuggable=1 then save file
4) repack ramdisk (cpio.gz)
5) repack into boot.img, using zimage + new packed ramdisk, using correct mkbootimg arguments
6) flash using fastboot
7) enjoy
PRO TIP:
Use ONLY LINUX FOR ALL OF THIS ELSE DEVICE WONT BOOT

Thats pretty much exactly what I did. (I did the initial split under windows though I will try again.)
I used the mkbootimg arguments from SE's building kernel blogpost.
help please
please help me somebody i have a problem i cant seem to fix , i flashed the doom kernel then flashed 4.3 icream sandwhich rom exactly like it said to do in the instructions re-booted ,It all booted up fine i played about with the rom for a few hours as you do then i went back to my backed up stock rom ,but heres where the problem happens on restoring my stock rom for some reason my camera doesnt work and playing youtube videos doesnt work and also when i try downloading from the market it just sits there for ever saying downloading but nothings happening i would be really greatfull if somebody can help me resolve this problem thanks..
are you asking this in all thread's?

Hey Doom, I'm trying to follow this, and I'm getting stuck
I downloaded the R800x 2.3.3 (3.0.1.E.0.88) TFT from here: http://forum.xda-developers.com/showpost.php?p=19438024&postcount=12
I unzipped it using xarchiver (installed on arch linux/available on sourceforge)
I ran unpack-kernelsin.pl, and I get two errors (that don't exit out of the perl script):
1) ramdisk written... gzip: no such file or directory
2) cpio: premature end of image
When I try to cpio-ing the ram disk, my computer just sits... How long should I wait, I have a netbook (i know, not the best for doing compiling) and the longest i've let it sit is about 10 minutes (i'm about to let it sit overnight to see if it'll work itself out)
If you could give me any pointers, that'd be outstanding
Thank you,
Pax

for such things send me p.m.
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??
Dear specialists on the XDA,
Normally I ask no questions in order to save the precious time of people, however this time I have a problem which I fail to understand and cannot resolve using the documentation available on the internet.
I have committed extensive reading and know how to build software but am simply missing a link here.
Trying to boot a home build kernel on a oneplus7 pro device with no luck so far.
Here is the situation so far: I have after hours of headaches successfully built myself a kernel straight from the stock sources. No alterations just using the msm8150-perf.defconfig file and build successfully with clang 9.0.5. There are only a few warnings nothing serious and the dtb has many warnings but I get what I need. I have done this before for my oneplus 3 and indeed the kernel was working.
Assuming the kernel is in a functional state. I used the latest version of android image kitchen to unpack the boot image which I extracted (from the right active slot) and replaced the kernel file and repacked the boot.img successfully into a new image file.
No luck after trying to boot into the image using fastboot. Screen hangs forever. Bootloader is unlocked btw
So far I have tried:
1. Signing the boot image using boot signer
2. Unpack/repack using android image editor (which signs the image)
3. Repack using different kernel image files from xda which I expect to be good and working
4. Flash signed image straight into active slot.
5. Completely read through the anykernel1, 2 and 3 scripts to find answers.
No matter what I try. Kernel does not boot. Either the fastboot screen hangs forever or the system reboots back into its currently working active slot.
I have to add that this bootimage contains magisk.
I am out of ideas. Please help me out. I hope that you can point me into a good direction.
