Hello, I just software CFW'd my PS3 like a lot of people are doing now. I'm new to using CFW and from what I understand QA flagging allows the PS3 to downgrade to another firmware. I believe Ferrox 4.82 comes with QA Flagging enabled. When I try to install Rebug 4.81 it says the files are corrupt. Can anyone point me in the right direction? Thanks!
