Hi, I've just started soft-modding my psp slim (model:2001) and have just recently updated the firmware into OFW 6.60 and am attempting to use the CFW for 6.60. I have tried multiple versions of CFW 6.60 pro update, but every time, the outcome is the PSP logo that comes up before initializing a game, then a black screen where I have to reboot in order to return to the main menu. What am I doing wrong?
