Hey guys,
Currently I'm planning to learn a thing or two about building Kernel...
As per Knzo's posting at G+ here are the steps:
Manuel Saraiva - Oct 11, 2011 - Limited (locked)
Since I'm receiving so many requests on how to build and tune CM's kernel for Optimus Black, here's a short tutorial:
0. You'll need: a linux distro like ubuntu, some packages (check CM's wiki on how to build a kernel for a list of them) and some GB of free space.
1. Go to github.com/cyanogenmod/lge-kernel-sniper, download and extract.
2. You'll need a .config file to build. Either pull it from /proc/ (check CM's wiki on how to build a kernel for the full command) or build it from CM's defconfig (located in arch/arm/config).
3. Download a toolchain of your choice. CodeSourcery is fine. I personally use Linaro though.
4. Edit Makefile and change the ARCH flag to arm and the CROSS_COMPILER flag to your toolchain's bin folder, ending on arm-linux-eabi- or whatever.
5. Do the desired modifications.
6. Build. You'll get a zImage and the modules (.ko).
7. Since Koush's AnyKernel doesn't work on Black (afaik), just unpack a boot.img (obtained from a nandroid or something) using unpackbootimg tool or a kitchen like dsixda. Then replace the zImage, repack.
8. Now create a flashable package with the boot.img and the modules in /system/lib/modules.

Anyone tried it? If yes, please share your knowledge so we can learn together....
Currently i'm stack at Linaro setup, it has too much dependency and i'm failed to instal qemu-arm-static...
I tried to run ./configure but there is error
Error: zlib check failed
Make sure to have the zlib libs and headers installed.

I've tried to intall zlib, but still no luck......
Regardig to Linaro, you don't have to install anything.
Once all installed (previous to toolchain), you only have to download linaro (in my case linaro 4.5 to match gcc version) in .zip version (not binary to install) and decompress it into a certain folder. Then, you have to add linaro's folder to path and set CCOMPILER to new linaro's bin folder (+ the sufix of the files contained into it).
Regards.
hi, help me
after comand make ARCH=arm CROSS_COMPILE=$CCOMPILER -j`grep 'processor' /proc/cpuinfo | wc -l`

I cannot get .config from /proc/ to build the kernel... where is it supposed to be?
At /proc/ you can found config.gz, but if you rename it to .config, you get it!

I even cannot find config.gz from /proc/.. I am using Nova Rom anyway.. or should I use CM to get it?

You need config.gz from a running kernel like the one you want to compile.
Then, if you want to compile CM7, you need config.gz from /proc/ of a OB with CM7 running.
If you don't have a OC with CM7, why do you want to compile that kernel?
Regards.

I see, thanks for the explaination Huexxx...
Right know I'm still on the stage of learning, it's still far away from dev-ing. And also OB is my only phone, so I can't experiment too much on it...
But I had boot.img from CM7 SK7-2 nand backup in my phone and I tried to extract the .config from it using script as told in CM wiki page:
Retrieve a working kernel config from the device, and unzip it:
adb pull /proc/config.gz /home/user_name/android/kernel/cm-kernel/config.gz
cat config.gz | gunzip > .config
Alternatively, you can pull the .config from the newest boot.img
scripts/extract-ikconfig boot.img > .config
Click to expand...
Click to collapse
But i got error:
scripts/extract-ikconfig boot.img > .config
bash: .config: Is a directory
Click to expand...
Click to collapse
Only two things:
- The boot.img from SK7-2 doesn't have config info.
- Where you are attemting to extract the file, seems to have a .config folder... Try with another name (config.gz for example) and then rename it...
Why not ask for a config.gz from anybody?

hi guys,i decide to join in
donwloading toolchain,very slow speed here
let me explain my problem, i've created a .ftf (kernel for xperia x8) and it is boot up but i missed some files inside the ramdisk, so now i need to repack my new ramdisk folder into ramdisk file and i don't know how to do that .
Read my guide on how to compile and put together a custom kernel for the X8: http://forum.xda-developers.com/showthread.php?t=1923240
The method (whatever it is) you are following is not correct for any Android phone.
Oops. I guess it isn't mentioned there.
Basically what you have to do is open up a Terminal in Ubuntu. Navigate to your ramdisk folder (the one that contains the init.rc, init.usb.rc etc.). Then issue this command:
Code:
find . | cpio -o -H newc | gzip > ../ramdisk
Grab the ramdisk from one directory above your ramdisk folder.
Sorry for the confusion.

i don't understund one thing, when i'm getting the ramdisk file? when compiling the rom?or the kernel?
i've compiled cm10.1 rom and i need to change the bootclasspath
You have to unpack a working kernel with DooMLorD's kernel.sin unpacker. You'll get the ramdisk. Then edit the BOOTCALSSPATH in init.rc.

Name the folder that has the ramdisk contents something like "XYZ" and put it in another folder named "ABC". Then issue this command.
So basically the structure would be:
/ABC/XYZ/* /*ramdisk contents have been denoted by * */
And after issuing the command grab the ramdisk from ABC folder.

yeah thank you now it's working but i think something is missing , can you help me in developed kernel for cm10.1 ?
i already compiled the rom but now i'm struggling with the kernel part , i can send you all the files for the ramdisk and if you can put together a working kernel it will be great and i can move on and fix the problems with the rom itself
Look man. I can download the source and help you compile the kernel and the ramdisk. But as Daveee10 has said, even if you get it booting, there are tons of things that need to be backported (which is extremely hard) for it to work properly. So it's almost like choosing a route that you know will lead to a dead-end. But I'll help anyway.

P990 ROM Converter
from New BootLoader to Old and vice versa
Actually this tool is Tonyp’s idea. All credits to him.
He asked me if I am interested in making a script and automating the rom porting from one bootloader to the other and he assisted me with all the changes that need to be done.
Due to different EOL (end of line) termination in text files between UNIX-Linux (LF) and windows (CRLF), I had to make bash (linux) scripts necessarily. The good thing is that the tool can be used in both windows and linux systems.Installation:
Download and extract the attached ROM-Converter-tools.zip package anywhere you like.
Download and extract in the same folder, a newer ROM-Converter-scripts.zip if exists.
For Windows systems only:
Install Cygwin following the instructions below:
Download setup-x86.exe from here http://cygwin.com/install.html
Attention!! Even if you are running x64 windows system install the x86 version. DO NOT install the x64 cygwin version because two binaries (mkbootfs.exe & mkbootimg.exe used to pack boot.img do not work properly).
Run the setup-x86.exe, when the list of packages is shown make sure you add the following:
Expand Archive and select zip & unzip to be installed
Expand Utils and select cpio to be installed
Expand Perl and select ‘perl: Larry Wall’s Practical..’ and perl_vendor to be installed
(If you are already using cygwin run setup again and add the above packages to be installed.)
For Linux systems only:
Download the attached linux-mkboot-binaries.zip (mkbootfs, mkbootimg), extract them in tool folder and remove the windows ones (mkbootfs.exe, mkbootimg.exe).How to use it:
Put the source ROM.zip(s) in the 'source_zips' folder (otherwise you’ll be prompted to drag n’ drop it in terminal)
Open Cygwin. Type cd (leave a space after cd) and type /cygdrive/c/dir1/dir2/../ROM-Converter-tools
where “c/dir1/dir2/../ROM-Converter-tools” is the full path of the folder you extracted the convert-tool package (e.g C:\dir1\dir2\..\ROM-Converter-tools) and press enter.
In case of long pathname, instead of typing the whole of it, use one of the following tips to easily change to tool's path.
Tip#1: After you type cd , drag n’ drop from windows explorer into cygwin terminal, the folder "ROM-Converter-tools" and it wiil automatically be converted to ‘/cygdrive/c/dir1/dir2/../ROM-Converter-tools’ press enter and that’s it.
Tip#2: After cd /cygdrive/c/ type the 1st one or two letters of the next subdir and autocomplete it's name with TAB.
Type one of these commands in cygwin terminal:
Code:
./convert_rom.sh -stepmode #--> starts in step-mode for debugging purposes
./convert_rom.sh #--> runs unattended (with no pauses).
What it does:
The scripts use as input the 'files2convert.txt' which contains all possible files needed to be converted.
This is for compatibility purposes to support as many roms as possible and for future changes.
files2convert.txt
Code:
/ramdisk/fstab.star
/ramdisk/fstab.p990
/ramdisk/init.cm.rc
/ramdisk/init.cm-star.rc
/ramdisk/init.star.rc
/system/etc/vold.fstab
/system/bin/setup-recovery
/system/bin/check_sdcard.sh
/META-INF/com/google/android/updater-script
More files can easily be added for conversion if needed.
The converter:
Extracts source ROM zip
Unpacks the boot.img
Reads the above files, replacing partitions' mount points, among some othe things, for the selected bootloader
Replaces the kernel image for the selected bootloader
Builds new boot.img
Creates new converted ROM zip
Under 'kernels' folder there are already included the two latest Kowalski kernel images (zImage) for old & new BL and its modules.
You can add more kernels and you’ll be prompted to choose the desired one when converting a ROM (if more than one is found ).
Read how to do this:
kernels folder contains all kernel images (zImage), kernel modules and any other file the kernel needs.
for each kernel there are:
file(s) named: prefix-KernelName[-ver].zImage
folder(s) named: [prefix-]KernelName[-ver]Kernel
where:
prefix must be oldbl or newbl (depending on which bootloader this kernel is for.
KernelName[-ver] is whatever you like [and optionaly its version].
zImage is the extension of the kernel image.
How to maintain kernels folder
A. Update existing kernels
Download the desired kernel package and open it.
Replace its kernel zIamge in kernels folder
Extract its modules and any other file needed and replace all existing ones
B. Add kernels
Download the kernel package and open it.
Find the zImage inside package and extract it into kernels
Rename it this format: prefix-KernelName[-ver].zImage
Create a folder named: prefix-KernelName[-ver]. It will be used to keep kernel's modules and other files needed. If this kernel is released for both bootloaders and its modules are identicaly on both bootloaders (like the existing kowalski one) then name the folder only KernelName[-ver] (without prefix).
Inside this [prefix-]KernelName[-ver] folder create a subdir tree lib\modules
Extract in lib\modules all kernel's modules from kernel package.
If any other file is needed by kernel then create it's subdir tree (assuming that [prefix-]KernelName is the system folder of the kernel package) and extract it there.
Attention: Current version will hopefully work on CM-based ROMs.
Stock based ROMs need more files to be changed, but they are not included yet, because I don't have the whole info needed.
Hopefully @rugglez or someone else will be willing to help.
Till then avoid converting stock-based roms, (or if you do try, then after converting replace the boot.img in converted rom and "system/lib/modules/*" at least with a working boot.img and modules from another stock-based rom, for this bootloader of course. This could work but I am not the expert to say)
ChangeLog:
Version 1.0 Aug 23, 2013
- The two convert2xxx_bl.sh scripts are now integrated into one script convert_rom.sh.
- The new convert_rom.sh also accepts an optional switch [-stepmode].
Code:
./convert_rom.sh -stepmode #--> starts in step-mode for debugging purposes
./convert_rom.sh #--> runs unattended (with no pauses).
- A technique added to preserve whitespaces in converted lines. So converted files keep margins and whitespaces of the source ones.
- Script checks whether source rom is a newbl or an oldbl one, displays an error message if rom is not for the expected bootloader and exits.
Version 0.3b Aug 23, 2013
-a typo fixed in converting scripts
Version 0.2b Aug 23, 2013
-liblgeril.so is also replaced with the one for the oldbl or newbl accordingly.
-A forced removal (switch -f) added when removing files and dirs just in case.
-Converted ROM name will be built automatically from the source name suffixed by -oldbl or -newbl accordingly. (If source rom's name contains 'newbl' or 'oldbl' it will be substituted by 'oldbl' or 'newbl' accordingly)
-Converted ROMs are now created under 'converted_roms' folder.
-Converting to oldbl: Files 'check_sdcard.sh' and 'lgdrm.img' are being removed if exist (as they are not used)
-Converting to newbl: Charger dependent images are also copied in ramdisk (not only the charger binary).
-Kernel modules will also be replaced with the ones coming with specific kernel image.
-Kowalski Kernel images & modules, in kernels folder, are replaced with latest ones dated:2013072013. (it was my fault, the previous ones were downloaded from "releases" download folder and were dated 20230303)
-Some changes in display messages.
Version 0.1b Aug 19, 2013
-1st beta version
I really don't want to have all of the credits.
While it's been my idea to create such a script and I provided the input on what needs to be changed by the script, I couldn't have done it on my own.
I both lack the skills(!) and time.
Steve would say:
Anyways, don't leech. If this helps someone, donations are appreciated:

Thanks Android tool guru @spyrosk....and thanks @tonyp
just trying it out. A small comment....people might mistake this....there is no space between the / AND convert2new_bl.sh command line....should be the same with oldbl.sh command....isnt it?
thought of giving a feedback about this.
thanks once again

Hi my friend,
First of all sorry again for deleted post(s)..
and thank you.
The "typo" is corrected. Actually it was not a typo but I have noticed that it happens when pasting text from another editor.
Which ROM did you try to convert?
battery charge script cannot be opened error??? On which step did it happen?
I don't try to open any battery charge script
Did you add any file in "files2convert.txt"?
Very interesting tool.
Last july 7th I asked you if this were possibile and didn't have any reply. Now I'm happy that Tonyp convinced you.

EDIT:
Just now, I tried to do the PAC Man by Metallica for the Old BL and had the same error of battery charge script....
Same in Django Adios Amigo 1.6.5 to OldBL....see the script error below:

I just converted Avatar-3.1 from old to new. No errors at all.
I don't like the write-protected error: rm: remove write-protected regular file `out/ramdisk/charger'
So it tries after that to remove the out directory but of course it's not empty.
Well,
Remove out directory manually and try again from the beginning..
After step 5, Before you continue to next step try to remove the whole out directory manually again.
Try also to give your account full control to the converter's folder.
This problem seems to he a windows security permission issue. Are you an administrator on the system you use?
-------------------------------------------------------------------
Stock based ROMs need more files to be changed, but they are not included yet, because I don't have the whole info needed.
Hope @rugglez or someone else will be willing to help.
Till then avoid converting stock-based roms,( or after converting replace the boot.img in converted rom with a working boot.img from another stock-based rom for the same bootloader of course. This may work)
Try ONLY CM-based roms.
I forgot to write it in OP. I'll do it asap.

If you have seen the dev section....I was porting a few ROMs from Old to New BL including the stock ROMs.
So, I will send you the list by PM.
I will try the CM based ones with manual clearing...and will check that
EDIT: I am the administrator...so normally only one account and I have that rights too

Okay, I just used the converter on Win8 x64 to create an oldbl version of my CM10.2 ROM.
I have uploaded the resulting zip here: http://tonyp.basketbuild.com/index.php?dir=main/CM-10.2/oldbl-untested-builds/
It is untested - so do a backup!
I will post the steps I took, this might help some people who never worked with tools like this.
Please try it out with different ROMs - and if the resulting zips work a) post that here and b) share the zip in the respective threads for others to use
If you have any erros post the complete cygwin output here.
To get it do a right-click into the cygwin window, then press Enter - it's now copied into the clipboard!
Okay, off we go:
Preparation (one time only):
Downloaded cygwin. and install it
The path C:/cygwin is perfecly fine.
Just press Next until you get to the paket selection, then use the searchbox to quickly get to the tools needed:
(just click once on it, the first checkbox will get checked. The second one is for the sourcecode, you don't need that).
- zip (Archive)
- unzip (Archive)
- cpio (Utils)
- perl: Larry Wall’s Practical (perl) (you might have to open "perl" and look for it manually)
- perl_vendor (perl)
Downlaod the zip attached at the OP, extract it.
I extracted it to C:/temp/ROM-Converter-tools/
done
ROM conversion:
Open the Cygwin Terminal (either in the start menu or execute the Cygwin.bat at C:/cygwin/)
Put the ROM zip into the source_zips folder
Type:
Code:
cd /cygdrive/c/temp/ROM-Converter-tools
Needs to get adapted to your path if you extracted the ROM-Converter-tools somewhere else.
My path is: C:/temp/ROM-Converter-tools/
(Hint: after /cygdrive/c/ autocompletion with TAB will work!)
I didn't try the drag&drop tip of spyrosk.
Type:
Code:
./convert2old_bl.sh
(or convert2new_bl of course if you're going the other direction)
Follow the instructions on the screen,
As it's still in the debug mode you need to press [enter] a couple times.
This will change in the future.
Done, your converted ROM will be in the out_oldbl or out_newbl folder.
do this tool work with CM7

Hummmmm, I tried experimenting, and it happened to me the same as the partner "SREEPRAJAY"! ...
Here are the errors I had during the experiments (three files *. pdf);
Hrmph.
Was running the latest CM 10.1 nightly. Rooted, old bootloader, CWM Recovery 6.0.3.1.
Made a Nandroid backup. Wiped everything from recovery, factory reset, flashed this :
http://tonyp.basketbuild.com/download.php?file=main/CM-10.2/cm-10.2-20130821-UNOFFICIAL-p990.zip
According to CWM all flashed and well. I rebooted.
Phone's bricked, won't even boot to recovery, gets stuck in the LG logo. Ouch. Halp ?

I know ! ( NEVER flash anything as soon as you wake up without checking twice, kids. )
I saw the one for old bootloader for the 20th, moved up a directory, happily flashed the one for the 21th... and for the NEW bootloader.
Don't have access to a laptop to tinker and won't for a few days. Sigh.

No, and it never will.
GB relies on the old bootloader. It would be a lot of work to make it compatible, which isn't worth the trouble at all.

uhm ... in my case it got stuck at CM booting logo ... is flashing it recovery sensitive?

Ah that's a shame. spyrosk needs to have a look at that when he gets some free time.
You did a full wipe didn't you?
If you did it sound like an error in the fstab.

Your partitions are borked and you will have to use nvflash.
I'm sorry about that although I don't really know how you came to the idea to try the untested oldbl builds when you got no PC around to recover.
This could have even happened with the correct rom - again, it is completely untested.

I did the full wipe (I checked: I used the ext4 full wipe zip by dr4go for the old bootloader, as I usually do, using CWM 5.0.2.8)
Has anyone tried rebuilding Safestrap for the bionic?
Source is here:
https://github.com/Hashcode/android_bootable_recovery
The readme.md points you to the TWRP build thread:
http://forum.xda-developers.com/showthread.php?t=1943625
I have CM10.1 installed in ~/android/system. I've been building and loading it on my bionic, and that's working fine. Per TWRP instructions, I also rebuilt CWM recovery without error (make clean && make recoveryimage).
Reading through the TWRP instructions, it calls for replacing your bootable/recovery CWM image with the TWRP build tree. Rather than do this, I instead wanted to pull down SafeStrap's git repo into its own dir seperate from the CM10.1 build tree (for my own sanity), and use a symlink to make it look like I had.
I cloned the safestrap repo into ~/android/safestrap/android_bootable_recovery.
I renamed my ~/android/system/bootable/recovery directory (to recovery.orig) and symlink'd so that ~/android/system/bootable/recovery maps to ~/android/safestrap/android_bootable_recovery).
When I try to build (make clean && make recoveryimage), I get a couple of errors right away:
bootable/recovery/Android.mk:18: bootable/recovery/../../external/safestrap/safestrap.mk: No such file or directory
build/core/base_rules.mk:123: *** bootable/recovery: LOCAL_BUILT_MODULE and LOCAL_INSTALLED_MODULE must not be defined by component makefiles. Stop.
There is no ~/android/system/external/safestrap directory for that safestrap.mk. A find command shows that safestrap.mk doesn't exist in either ~/android/system/external, or in the SafeStrap source.
I have been assuming that CM10.1 targa branch was safestrap friendly, but I don't see any of the TWRP switches in any of the BoardConfig.mk files or anywhere else for that matter.
Is there a special CM10.1 branch that includes these TWRP-friendly tweaks, or are they sitting in someone's working copy...? If so, anyone care to share them?
In return, I'll write up a good build summary and perhaps we can get hashofcodes to add it to the readme.md...?
Thanks,
- Josh.
NOTE: Unfortunately I've had to remove links from this post because I'm a new user. I'll add them back in once I have enough posts.
I've been trying to edit a file in boot.img from the CyanogenMod 12.1 (huashan) nightlies but I'm experiencing some issues finding the right tools/methods for the job.
Most scripts I've found expect an Android Magic number at the beginning of the file but this simply isn't there. It seems there is no header at all that matches the specification from bootimg.h (missing link) though I did discover the cmdline argument at the end of the file with a hex editor.
After searching and experimenting for hours I found a script here (missing link) which enabled me to extract the kernel and ramdisk images despite the missing header but now I don't know how to repack the files into a boot.img of the same structure.
I've tried the following but it results in a boot.img that is about 40% larger than the orginal (despite me only adding one line of code) and has an entirely different structure (with an Android Magic number, etc.).
Code:
mkbootimg --base 0x00200000 --pagesize 2048 --kernel boot.img-kernel.gz --ramdisk newramdisk.cpio.gz -o newboot.img
I found this resource (TWRP, missing link) which mentions that Xperia devices have special boot images (or something like that, I didn't understand all of it) - this might explain why the boot.img structure is so different - but I can't find any further documentation on this or instructions on how to deal with the format.
The Xperia devices have a recovery-in-boot arrangement. This means that the recovery is booted using the regular kernel / boot image in the device. Team Win has worked with the FreeXperia device maintainers to come up with a way to extract the ramdisk from the FOTAKernel partition and use the ramdisk from that partition instead of the recovery that is included in the boot image of your device. This means that if you install current CM nightlies and flash TWRP to the FOTAKernel partition, you will be able to use TWRP instead of the CWM or CM recovery that normally comes in a CM boot image. Other boot images including stock kernels can be repacked to include this extraction utility to allow you to use TWRP from the FOTAKernel partition. This setup allows you to choose what recovery you want to have installed and allows you to update your recovery more easily. Unfortunately this setup requires that the boot image that you have installed include the ramdisk extraction utility.

So now I'm at a loss at how to continue. I would much appreciate any pointers, ideas or help in general.
@infernalpostcard , hopefully this tool made by @Adrian DC will help you out.

Thanks. This looks really promising. I'm trying it out now...
EDIT: It worked! This is exactly what I needed. Unfortunately what I was actually trying to achieve (apply a fix to break a boot-loop my phone gets in, due to an encrypted filesystem) didn't work so I'll have to come up with new ideas.
