Hi,

you can use the attached script.
Unzip file and you will get split_bootimg.pl file.
Use below command to extract ramdisk from boot.img

unzip split_bootimg.zip
chmod 777 split_bootimg.pl
./split_bootimg.pl boot.img

The output will produce ramdisk.gz file.

What command are you using? It should be

gunzip boot.img-ramdisk.gz

The "boot.img-ramdisk.gz" maybe was compressed in lzma format. So the correct command would be:
lzma -dc ../boot.img-ramdisk.gz | cpio -i
just try..

Hi,

Even I'm facing the same problem. Even lzma didn't help...

for A75 the boot is not in usual gunzip format



For extracting the A75 boot, you need these special Files :
MT65xx boot.img scripts !!!
