my BD drive is damaged and i have to return my ps3 to Sony. i have currently CFW 3.55 on it and i have also some questions:
1. how can return to any OFW?
2. is Sony able to prove any CFW installed before? (before CFW i used a JB)
3. normally Sony will return a refurbished ps3. If there will be the 3.56, can i install a CFW again?
