On my PSP Go N1001 I installed CFW 6.39 ProB8 and it was working fine for about a week then all of a sudden when I started quick revocery, it rebooted normally, but when I click on any system storage it just freezes. I have tried downgrading to 6.20 and trying the 6.20 Pro B8 but when I installed it, the same problem happened. Then I tried the 6.35 Pro B8 with the same result. Please help me. Also is there any way to convert eboot.php downloaded from the psn store to Iso to clean up space on the psp and so I can play them while on cfw.
