    Default I want to downgrade 4.01M33-2 to 1.50

    I want to downgrade my PSP with 4.01M33-2 firmware to 1.50 firmware so I can put the latest Sony firmware on it so I can sell my PSP.

    My PSP is not a TAO PSP and is an original FAT 1000 PSP.

    Just download and put the original sony 4.05 EBOOT in a folder labeled "UPDATE" (no quotes) and run it straight from the XMB. If that does not work run Hellcat's Recovery FLasher 1.21 and install the official firmware 4.01 and then just run update to get it to 4.05.
    I don't go on here much anymore. Find me on GBAtemp.

    Why not sell it as it is?

    People pay more money for Custom Firmware.

    I agree, because people don't want to go through the "hassle" of doing it themselves, they think it's way harder than it actually is...
