Recently my PSP's custom firmware just stopped working. I was running on 6.20 PRO-B5. My PSP crashed and when I turned it back on in System Settings it said it was running 6.20 official firmware. I tried reinstalling custom firmware but when I loaded the updater it just restarted my PSP. I tried using the recovery menu but that didn't work either. It would only stay open while I held R, so it wouldn't let me select anything. So I tried updating to 6.35. After updating to 6.35 OFW I ran the custom firmware updater for 6.35 PRO-B5 and installed it. After it was installed, however, it would not start custom firmware. I'm thinking that maybe I've semi-bricked my PSP, any help?
