I formated my hard drive using a computer and put it back in my ps3 slim. I booted my ps3. it asked for format the drive and plug in flash with firmware. i hit x and put in the flash with cfw 3.55 kmeaw. my ps3 booted without any problem. but now i cant play my backups. All of them hangs. Uncharted, killzone2 and marvell vs capcom works smoothly. But tekken6, uncharted2 and mgs4 hangs(before format and firmare installation they worked), sometimes on main manue somtimes at loading screen. when i quite the game by pressing ps button it reboots my ps3.
Now i wanna know if its the firmware thats messed up?
