I got a friend with a psp 3k, and very old versions of cfw 5.03 gen a\c. he's kind of a knucklehead, sobear with me... He used an "installer\loader", and now, he gets "gen a" on his xmb menu whenever he tries to load a cfw. It seems the old gen cfw was flashed on his psp 3k flash memory thanks to the "instaler\loader". Any way to actually fix this, install any other cfw and use the 503 kxploit?
