I've searched on google and I can't find a answer to this question. Can this method or another method mod / hack a slim god of war psp that has original firmware 3.95? I've heard there are different main boards in the slims, what's the difference and how to you tell them apart?

This thread is old, "*Updated 6/27/07*". Also, it's 2.00 - 3.50 OFW. As for a 4.05 downgrader, just use/make a Pandora battery and MMS. Click here for more info: http://www.pspmod.com/forums/psp-har...ery-guide.html (Easy-To-Use Pandora's Battery Guide)
