Hi, I just upgraded my psp to version 3.52 M33 then to the update #2. That worked out fine. Then I did the same for my brother's psp and it worked out fine until I put skins on. Of course I forgot to make a backup of his Flash0. It still sorta works, I can get into the recovery menu and I can even get around in the XMB, everything just is a little skrewed up. It wont read UMDs either. So I think the best move would be to get his PSP back to 1.5. How would I go about doing that. I assume somewhere in the recovery menu.. Thanks in advance.
