I have a psp 2000 My psp will only run my isos if.... 1. I have just installed my cfw 2. If I have used cpl flasher 3. Or if I get lucky. If it turns off or if I try to even open another game it will not open any other psp iso unless I do one of the 3. Which if they all fail I downgrade to 6.20 and re update to 6.60 Every other time it just freezes at the Sony logo. If I turn off Sony logo boot it turns black and freezes. I am using cfw 6.60 pro c2. I also use pops which works just fine. The main problem is that I am tired of having to downgrade my psp then update to play a game. Also my psp can never finish an update which I really feel like that is the cause I have no idea how to fix this. I cant finish an update, It goes to 99 then to 84. I looked up what may be the problem but all the topics are for people with Pandora batteries which I don't have. Any help would be appreciated.
