NOOO unless if u have playstation plus u can copy to storage and get someone on ngu to unlock and upload it 2 u

You can try to data transfer. There are plenty of game saves that can be copied that way, but I would backup my PS3 just in case it didn't work. It wouldn't harm your PS3 or anything it just might lose some data if it didn't work which I believe it would.
