I don’t know how to do it myself, but a really good place to find out how to downgrade is http://www.psp-hacks.com/
Sorry I can’t provide anymore info to help you, but that’s the site that I always see mentioned when it comes to downgrading. Shouldn’t cost you anything either so you can save your $100.
Hope it helps.
