OE was 3.50, I used unbricker that loads 3.71 CFW. PSP now starts CWF but without menus such as system settings, games, UMD, etc. it's just plain blank screen with date and battery information only on the right upper corner. I then realized that I can't load using unbricker to convert original 3.50 to 3.71 CFW. :blushing:. Please help
