Got my PSP 2000 working fine with the 5.50 GEN-D3 CFW, and got game to run just fine. My issue arises when I exit the game, then shut down my PSP. The next time I try to turn it on, it's bricked and I must run to my Pandora to put it back in a useful state. This issue only happens with ISO/CSO games and not physical UMDs. does anyone have a thought as to what's going on?
