i havent touched my psp in about a year and a half now. i had a CFW 3.52 m-33 or something like that, and i've decided now that i want to start using the official sony firmwares (as in, i dont want any CFW anymore) I was wonderign how i would go about doing this. if i just update now to the latest FW, will my psp brick? do i have to go back to 1.5, then update to the official FW? (if so, how can i get back to 1.5 using recovery mode?) thanks a lot guys.
