Please clarify this for me, I just got a PS3 yesterday so I don't know much things about it. I have a PS3 Slim 120GB serial CECH-3001A. Originally it came with 3.72 and I accidentally upgraded it to 4.31 which is the current one. I already know that my console cannot be downgraded to 3.55 to use CFW.
But does this thread means that I can install this CFW over my 4.31 and my backed up games will work with it? If yes, will it work on discs only or can I use packages and homebrew?
