I'm fairly new to the PSP hacking scene (just bought one today), with a PSP Slim 200X that's hackable (it's one of the God of War ones, refurbished). There in lies the problem. Apparently the refurbishing also included an upgrade of the OFW to 6.20. I want to install some homebrews and possible load PSP ISO's, but I am unable to install the CFW necessary for homebrews and ISO loaders. I have two options (as far as I know, which isn't very far). First is to use a (premade) pandora battery and MS to downgrade to 5.3 and install the CFW there. Second is to find either a CFW for 6.2 or find a less intrusive way to downgrade to 5.3 What is the opinion here? Would a pandora battery be the simplest (and "fastest") method?
