*** I TAKE NO CREDIT. I JUST MADE A GUIDE TO HELP YOU***
A STEP BY STEP TUTORIAL :
I find many people struggling with unpacking a boot image and expecially repacking it. So here is a simple guide to unpack and repack the boot image.
>You need some tools so make sure you download all these.
List : (links available at bottom of page
split_bootimg.pl
repack_bootimg.pl
dsixda kitchen (you need some files from here)
Not to mention, a linux based system
> First you need to make some correction to repack_bootimg file(if downloaded from other source) . open it using gedit or some editor.
> check third line from bottom which is starting with system...If it is ending with $ARGV[2] then make this change
Add --base 0x19200000 and then close with " .
This now should look like
$ARGV[2] --base 0x19200000");
> Save it and exit. Now place boot.img and the two files in a folder(create new one. Don't mess it up)
> Now go to dsixda kitchen folder >tools >mkboot and copy all the files to your working directory
> Now you have mkbootfs.c and mkbootimg.c files along with needed header files. You have to make them executable. For that, run this command
gcc -o mkbootfs mkbootfs.c
change the permissions
chmod a+x ....(path)/mkbootfs
Now do the same for mkbootimg.c
gcc -o mkbootimg mkbootimg.c
change the permissions
chmod a+x ....(path)/mkbootimg
Now you are ready to go. Just navigate to directory in command prompt and type
./split_bootimg.pl boot.img
(or)
perl split_bootimg.pl boot.img
you will get some files. one is kernel and other is ramdisk. extract ramdisk.gz. Now again extract ramdisk(cpio file) . Make necessary changes.
To repack, use this command
perl repack-bootimg.pl <kernel_name> ramdisk_directory_name boot.img
( you need mkbootimg for this to work)
Bingo you have a boot.img which is ready to test.
