I was trying to downgrade from cfw 5.00 m66 to cfw 3.71 because the psp kept pausing itself i thought if i went back to a previous cfw it mite stop the problem,
But now i cant do anything with the psp all i get is the original background with no icons. No UMD will start up so i cant try to upgrade or anything like that.
If anyone could help me with this problem i would be greatly appreciated

just download the "Hellcat's Recovery Flasher" on your psp and 371.pbp... put the 371.pbp on the RECOVERY folder on the flasher... after ur done, unplug your psp and run the flasher... then some questions will ask, if u want to downgrade your psp to 3.71 m33, and format flash 0... after the downgrading is done, your psp will shut down... after that the default settings will appear... and you will get a blue screen with many languages... this isn't mean that your psp is bricked... and then presto... your psp fw is now 3.71 m33... hope this helps...
