[babyjoker510]

any firmware that is just numbers is Official. ALL CFW's have a number AND letters; E.G.

Official 3.90

CFW 3.90M33-3

I have a PSP Slim with D3 on it and I had a little spill on it but I grabed it in time and removed the battery dried it and it worked. but i took the battery back out just incase and I turned it on the next day it gave me Initial setup but no buttons respond. but when i go to recovery menu buttons work then so how can they ignore me when it goes back to initial setup? brightness and volume are the only two so little help here?
