I currently restoring (full system) my ps3 idk if it goes back to its original firmware. if not i will need to know how to downgrade from 4.31 to 3.55 so i can jailbreak my ps3. i am worried about getting banned from psn so please help me figure out what to do. i have hacked plenty of things but this the hardest ive done so far. I have a CECH-2001B that is all i know about it because i got it from a friend and then did a system restore since his firmware was 4.31.
Firmware Wanted- 3.55
Reason- To Jailbreak
