1. Get boot.img via dump_image or native’s

dump_image boot /sdcard/boot.img

2. cut header

dd if=boot.img of=boot_no_header bs=2048 skip=1

3. find the begin-addr of ramdisk firstly, gzip’s magic number 1f 8b 08

od -A d -t x1 boot_no_header | grep "1f 8b 08 00"

4. if the begin-addr of ramdisk is 2388480, ROM Version A60_S155_110830. Kernel is here

dd if=boot_no_header of=kernel bs=2388480 count=1

5. ramdisk is here

dd if=boot_no_header of=ramdisk.gz bs=2388480 skip=1

6. extract ramdisk

 
mkdir ramdisk
cd ramdisk
gunzip -c ../ramdisk.gz | cpio -i

7. Do anything you want
8. Pack boot.img, updated 2011-10-27 Wrong for mtk’s

 
mkbootfs ./ramdisk | gzip > new_ramdisk.gz
mkbootimg --kernel kernel --ramdisk new_ramdisk.gz -o new_boot.img

Coder, boot.img, extract, lenovo a60, mt6573, ramdisk, spice mi350, unpack
