I wasn't too sure what to put as the title but recently I've had some problem with games and I was told the only option is by restoring it back to factory settings or something along those lines.
I've just downgraded from REBUG 4.70.1 REX to 3.55 using a REBUG 3.55 999 Downgrader which worked and I'm now on 3.55CFW.
My question is how would I go about resetting my ps3, keeping it on 3.55 or installing a higher CFW that'll wipe the PS3 but it'll still be able to install CFW on it.
