My ps3 hdd got corrupted few days ago. At that time it was asking for System Restore but i just switched it off and didn't do anything. Today it doesn't even ask me to do system restore. It tells to put a fw of 4.40 or above. If I update my firmware to 4.46 which I downloaded before installing multiman and everything, will I be able to play backup games or it will be become like original and then I have to remod it?
