Ok so i had a new psp version 2.71 fw. I then decided to use the winstaller from xtrusion(i think thats how you spell it) to get it down to 1.5 fw. i got all the way to where the power turns off and you then have to turn it back on and get that blue screen BUT when i went to turn it on my screen stayed black but the green light stayed on. I read all kinds of stuff on here or google and such but cant find an answer to if it is bricked or not. i tried leaving the battery out for a few days, leaving the psp on until the battery fully ran out then charged it and tried again, tried without the battery and the ac cord instead, blah blah blah. So i figure it must be bricked? So i also read somewhere that i might just need a new powerboard(not the mother board, this is just the power switch and the four buttons on the right). Has anyone else heard this to work? They are only a few dollars off ebay but I'd rather get some more proof first. If this doesnt work i guess i will just need a whole new motherboard . any suggestions/comments?
