i had tried modding my psp, and decided i was in way over my head. i didn't even have the skill to repair the trace i had cut, so i just put the thing back together so i could return it. for the heck of it, i tried turning it on, and WHOA! it works! with the downgraders and all now i'm finally going to get the full value out of my psp... woohoo!
one thing has me curious though, i definitely did cut one of the traces (i checked the continuity), but yet it still works? i've heard of cases where the psp wont respond to cutting that trace, guess i must be one of those cases. if so, the modchip wouldn't have worked for me either way, lol. i'm just glad i have my psp back :P.
(hmmm... i wonder if anyone will want to buy my slightly used UP. it'll be cheap ;))
