here is another 2.81 downgrade video

they both require a mod chip that has been installed on 2.71 before they upgraded to 2.81, i suppose otherwise the mod chip must not work.. i dont really know but i really want your guys opinions, even though its not for my benifit

yeah its the u.p doing thats, aka its the only thing that can do that, the guy is simply erasing the psps flash and then, the u.p. usgin its own files flashes over the nand flash of the psp, quite simple really

no the only way to downgrade from 2.81 is via modchip which pretty much, deletes flash
