    Hi Guys,

    I have recently upgraded my PSP to OFW 5.55 and have overwriting my previous hack on the psp.

    How do I downgrade my psp so I can play all my games from my MS and playing Grand Tourism on the UDM.

    My previews hack on the PSP was performed by someone else and currently do not know what to do.

    My psp is a 2004
    Motherboard = TA-085v2
    Pandora battery = I have a Tool 3.6v 1200mAh battery

    Anyone's help would be great.

    After downloading the above ^^ files, make the mms, put your pandora batery in, hold the L shoulder button and insert the mms.It would boot up showing a menu to install 5.00 m33-4.
    Afterwards you can update to m33-6 > gen-d >gen-d2.
