    My friend got a PSP with the firmware 3100oe-r, its some Chinese one I think, but he wants to know if it can be upgraded or downgraded to get a different custom firmware such as 3.30OE-A, I hear if you have custom firmware already, you can upgrade or downgrade to another custom firmware. Is this true? If so, how can I do it? Help appreciated.

    He probably just hexed his custom firmware to make it say 3100 OE-R. To upgrade or downgrade to a custom firmware, you have to install it normally using the GAME150 directories instead of GAME.
