So I snagged a pretty sweet deal of a PS3 fat 80gb model that is in great condition that came upgraded with 750gb HDD. It's on 3.55 but I have no clue where to start with CFW. Any tips and links to the absolute most up to date and safe guides along with the best CFW options? Looking into mainly using the system for playing PS3 and PS2 isos! Thanks! Also since it is a fat model is there any methods of absolute YLOD prevention?
