i got this 80020148 and i couln't fix it.
well i got a PSP 3000 running on 5.03 Gen-A (Full). when i try to get the menu by pressing SELECT it would't turn up. so i went through forum and found out that ultimate VSH menu will restore the prob. but it didn't either. it installed but when i press the L+R+ the menu didn't came. So any 1 can held me out in this matter..!! PLZzzz
