CFW for PSP

HELP- i have a psp running cfw 3.71 and want to update it to a newer one BUT
1) can i just update to the latest?
2)how do i update?
3) where do i get the updates(safe site)
cheers to all that help

1.Not the officially latest, but I believe you can try the newer cfw's.2.You place the file into "GAME" on your psp and run it like...a game.3.http://pspslimhacks.com/I would advise JUST to be safe, to locate the "5.00m33v6" firmware before trying "5.50GEN D-3" which is the current standard.

Yes, from experience with PSP's, I would go to M33-6 first.Then up to the GEN.I'm installing GEN on 2 PSP Phats tonight and have downloaded 5.00 M33-6 and 5.50 GEN-A, B, and D3 "Final Build". After I flash them first with the Pandora Method. :PDownload for 5.00 M33-6
Download for 5.50 GEN-D3 "Final Build"

Just don't update or attempt to update to any of the MAD or MAC type cfws. They are fake.
