Question about Sony PlayStation Portable (PSP) Console
Try to upgrade it 3.52 first and then jump to the latest 3.90. If you want to keep a CFW then check out http://www.dark-alex.org/ for more info.
Worst case you might have to 'unbrick' it with a Pandora's battery. See http://forums.qj.net/f-psp-pandora-discussion-207/t-guide-make-the-perfect-pandoras-battery-124530.html for a really good guide on how to make your own safely and the steps needed to 'unbrick' a corrupt PSP.
