[DEVELOPERS TOOLS] Unpack, repack boot.img, and editing boot logo

Samsung Galaxy Ace: Unpack and repack boot.img, editing boot logo
Ketut P. Kumajaya ketut.kumajaya @ xda-developers.com

Unpacking boot.img:

Code:

$ mkdir -p unpack
$ tools/unpackbootimg -i boot.img -o unpack

Extracting boot.img-ramdisk.gz

Code:

$ mkdir -p unpack/boot.img-ramdisk
$ cd unpack/boot.img-ramdisk 
$ gzip -dc ../boot.img-ramdisk.gz | cpio -i
$ cd ../../

Packing a new ramdisk:

Code:

$ tools/mkbootfs unpack/boot.img-ramdisk | gzip > unpack/boot.img-ramdisk.gz

Create a new boot.img:

Code:

$ tools/mkbootimg --kernel unpack/boot.img-zImage --ramdisk unpack/boot.img-ramdisk.gz -o boot.img-repack --base `cat unpack/boot.img-base`

Convert rle to png:

Code:

$ tools/from565 -rle < COOPER.rle > COOPER.raw
$ convert -size 320x480 -depth 8 rgb:COOPER.raw COOPER.png

Convert png to rle:

Code:

$ convert -depth 8 COOPER-new.png rgb:COOPER-new.raw
$ tools/to565 -rle < COOPER-new.raw > COOPER-new.rle

You should get "Recognized Developer" title, ketut.kumajaya!

If I have a Motorola Android device, maybe I can go back to www.MotorolaFans.com as a Developer

ketut.kumajaya, is it possible to resize Data,System and Cache on Ace? Maybe something like this...?

For example, the size of the partition of Indian (S5830DDKQ5) firmware are different (+1Mb to system and cache) from those that have been in all previous firmwares (KPN, KPH...).

EDITED---
guess we have to take boot.img from CWM backup images?
Is this doable under Windows? I tried but unpackbootimg wasn't recognized as a command

It's only for Linux and its variants and derivatives

Under Windows you can use JDK + Cygwin Custom Package + dsixda kitchen. Head to dsixda kitchen thread for more info. It's built for HTC but usable for Galaxy Ace / Mini (unpack / repack boot.img)
