Hey, im fairly new to the ps3 jailbreak scene, so far what i have done myself is downgrade the ps3 from 3.55 - 3.41, then install the jailbreak, and install the pkg file that allows me to play backups of games, Although this is where my problem stands. My backup of games keep giving me errors, although i have only tried two games (fifa 10 and just cause 2) i still have had no luck, im trying the 3rd game now. (wanted : weapons of fate)

I saw somewhere on this website that you can mod just cause 2 backup, and thats all i want to do. Any help on this would be greatly appreciated.
