Hey everyone, so I got my PS3 back from a friend who downgraded it and he took it upon himself to install 3.70 Rogero even though I asked for it to be left alone so that I could install CFW 3.55. Now I need to downgrade back to 3.55, but I'd like to use a fresh install so that I can see what I'm doing from the beginning so to speak. My question is, how do I go about doing this? If I enable QA flag on 3.70 Rogero and make sure that the debug menu appears, can I then just install OFW 3.55 through the recovery menu? I'm trying to avoid a brick, so I appreciate any help that you guys can throw my way. UPDATE: So it turns out that I can't install Toggle QA in order to qa flag my system and dehash it, because I get an "80029566" error any time that I try to install a package. Is it safe for me to install OFW 3.55 without dehashing first? I've heard that this 3.70 is actually just a 3.55 spoof, so would it brick if I just went and installed 3.55 over it?
