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!

Pandora battery. Downgrades anything.

[Chase817]

buy a spare battery (fat), then
1. make a pandora battery with it
2. create a magic memory stick
3. boot up psp and downgrade

if you want me to go into more detail i will

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.

Does anyone have a full tutorial for this? I want to run some N64 on my PSP, but I have absolutley no idea where to begin...
