yes,there is actually a way to downgrade 3.51,all you need is another homebrew enabled psp (if you have a friend who got one)to make a JIGKICK aka PANDORA's battery........try googling about pandora's battery,all psp's are now downgradable by this technique except the slims.....

Prob is that a newbie on psp is risking big on creating the pandora battery..I think that it is wiser to wait for another safer method to downgrade..unless you get your hands on a pandora battery.

Here are the Pandora files:

Read the readme to see what to do.

You need to have a psp with a custom firmware to create the jigkick battery and jigkick mem. stick.

I don't know how to downgrade using this.

Beware that once you use this you can't turn on your psp without your memory stick. Better not lose it.
