This worked for me, dont know if it would work for you. I had a semi-brick and i got it restored and i had 3.02 after that. So u can skip that part of the semi-brick cause u dont want a brick . 1: Download psp brick fixer(google it) 2: Connect usb to ur pc 3: Run brick fixer. example: ur psp drive letter is G, then write G: at the text box. 4: Turn off your psp if u didnt(hold power trigger for 6 sec up.) 5: turn it on and hold R till a blue menu pops up. 6: Choose the 3rd option. 7: this will install 3.02 OE-A NOTE: this worked for me when i had a brick, but i guess it will work without.
