3.71 m33-2 recovery error

hey guys,

im havin a big problem now....

i cant open the "configuration" in the recovery menu...

everything works fine except for the "configuration"

when i click it, the psp will go blank with the power LED on , then shut off by itself

all i did was quiting a game (in ISO file) then i cant play the game back, so im guessing it must be cause of the umd thing in the recovery (the np6009 thingy)

so, rite now i cant play a single ISO game on my system

any help would be appreciate :)

BTW: i own the ISO game and rite now its being borrow by my friend

EDIT:

or should i just format and reset the flash1?? anyone? please can sumbody help me?? :(
