What you do to it won't do much.

yes i know. my friend is looking for some checksum additions between the two firmwares.

He should just look for checksum differences in the FF file when it's mounted.

You dont understand. There are some file integrity checks that might have been added. His name is brendanj by the way and he knows what he is doing
