$ 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:

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