PSP Fat / Slim Upgrade Downgrade Service. Do you want custom firmware on your psp to play games from the memory card?

Console is downgraded to the firmware 3. 90 m33-2 or 4. 01 m33-2

Updates from this point can be done via network update on PSP and still maintain the M33 to run games from memory card.

After downgrading your psp I will again test to make sure its STILL 100% working.

This Service can be done on PSP's running any firmware on FAT or SLIM's

BRICKED PSP's ALSO DONE TOO!!!!

(No sound, No picture - But you get the Green power light, and it charges your battery)

I CAN FIX IT WITHOUT OPENING YOUR PSP AND BREAKING THE SEALS.
