I seriously screwed the pooch this time. Somehow, I got myself into a situation where my PC decided to format my mem stick without my consent. Have a PSP 1000 (FAT/PHAT) Everytime I put the 6.60 update back on, Everything ceases to work. It's all weird and broken. Do I even have to run the update, or what? My PSP had 6.60 firmware b4 I installed CFW about 2 yrs ago.
