    Hey there Heath_rox, i've successfully downgraded my PSP about 5 times but theres still a risk of bricking it (making it expensive paperweight). Anyway, for the 3.90 firmware i think you
    1) need a copy of the game Lumines or
    2) you need to create a Pandora Battery,
    i've only ever tried the first method and it worked fine but heres the link to the main website for that stuff: N00bz!

    its reallly easy to hack your psp.

    make pandora battery..

    open it up with a razer or small flat head screw driver. may take up to 5 minutes to get a clean cut.

    once opened look at the top chip it has 8 pins.

    cut the pin on the lower right hand side.

    put it back together

    insert into psp with magi cmemory stick which can be made easily witha number of programs out there.

    then .. upgrade to 4.01 m33 firmware

    Please note that the pin you have to remove is right next to the one that grounds. If you mess with that one and try and run your battery... Well, do so with a shield and industrial hazard-handling gloves. Sadly, the iPhone can't dial 911 if you are screaming. Need to jailbreak first.

    Seriously, the Pandora Battery is a great way to do things. I just bought a used PSP that had the right firmware and made one, then sold it and kept my newly downgraded one. Once you have the battery, it's a great money maker.

    Well Heath_rox,
    1) Im not sure if you need 2 PSP's for Pandoras? For Lumines Hack you can do it on one PSP, actually i think you only need one PSP for Pandora's Battery
    2) You need a spare battery for Pandora's but not for Lumines Exploit/Hack
    3) You can upgrade whenever you want without a hack but if you put a custom firmware on then i think you need Time Machine. Im not to sure about that though..

    And remember whenever you downgrade there is a risk of turning your PSP into an expensive paperweight!

    Good luck! I just realized that Lumines exploit is for 3.50 PSP's anyway.

    EDIT: Found a good link for you that shows unbricking and downgrading any PSP firmware: http://forums.afterdawn.com/thread_view.cfm/610313
