I have a Phat psp that was from when psp's just came out. my i recently got a game (final fantasy tactics) and i had to upgrade to play it. well i was a dumb ass and wasnt thinking and i let my gf us my psp. i not knowing that i had to upgrade my psp to play the game i let her use my psp and play the game. well she never told me that she updated it to 3.80 and here i am now trying to downgrade.
i have a spare battery and i removed the 5th pin. but.. i have problems now.
2 things...
1. When i try to use the mspformat.exe in the cmd.. i get an error and it doesnt format.
Error: "Write error"
ive formated the card with my psp and the same thing still happened. i formated my card with my comp in my computer and in the management menu. still didnt work.
2. So i thought i would try to run the "Pandora's Battery Firm.installer" and that doesnt work either. it wont load..
Error: "The game could not be started. (8002014C)"
idk what else to do...
