Hello, I wanna share on this blog about How to unpack, repack, split, mkboot boot.img

First, u need a file names Bootimgutils that u can download here.
After u done, u extract the file into a directory that u wanna and give it name (Like, Bootimgutils for the example)
.
Then, U grab boot.img file (U can grab it directly on onepack ROM. U can find boot.img on Code, if u use fullpack ROM)
*Don't forget to check the file permissions as executeable programs. Right-click, properties. Click on permissions tab

Go to terminal (Linux) or Cygwin (Windows)
Type these commands :

cd Bootimgutils
./split_bootimg.pl boot.img
mkdir ramdisk
cd ramdisk
gzip -dc ../boot.img-ramdisk.gz | cpio -i
cd ..

O.K. Up to ya to edit boot.img.
And, don't forget!
If u have done to change files.
U need to repack it anymore.

For that, u can type :

./repack_bootimg.pl boot.img-kernel ramdisk bootnew.img

or u can replace it.
U just need to change a command to be like this :

./repack_bootimg.pl boot.img-kernel ramdisk boot.img

*If u have backup of an original boot.img


Tips for unpack XZ compressed type:

./split_bootimg.pl boot.img
mkdir ramdisk
cd ramdisk

change your bootimg-ramdisk.gz > bootimg-ramdisk.xz.
And, then open its ramdisk content,
Drag to ramdisk directory u made before.

And, repack it
./repack_bootimg.pl boot.img-kernel ramdisk boot.img

Happy packing!
