Hi, I had my Sony PSP since launch date and stupid me updated to 3.0. I tried to downgrade it but it failed miserably and now my PSP is a brick. I ordered a new 1.5v Motherboard from Japan and its on its way now, but I have NO clue how to uninstall the old one and put in my new one. Is there any guide/tutorial of how to do that? Thanks !!!
