Ok i was trying to downgrade my 3.4oe a due to internet problems and when i did it corrupted my psp. Or so i thought. I decided to leave it alone and took the battery out over night then when i woke up put it back in and this time. It asked me to input time and date but then it would shut off. I could only access this when i leave the battery out. Also i did try holding R trigger for recovery menu and nothing came up.Please will someone help me.
