I got my psp from a friend and it's hacked. I really just want to use the the official firmware because all the hacked stuff is confusing and i tried buying a game from the playstation store and i keep getting a weird error code i cant find the answer to when i try downloading the game. I was told to go to the recovery mode menu and change the battery to normal, but that just made my psp lag a lot now. how do you go back? It's using 6.60 ME 1.8
