Hi, I bought a PS3 Slim 250go recently. There is already a Rogero 4.65 firmware. Can I format the console to restore factory settings ? Can I use my PSN account ? No ban ? Can I bought games and/or DLC on the PSN through the PS3 safely ? Can I play retail games without being ban ? Is there another firmware better/simplier to use or I can stay on Rogero ? Thank you very much for your help.
