Hi i was reading around since i just picked up my old PSP again and am looking into playing it again, im wondering how i can update my 3.90 M33-3 psp to the latest firmware to play hacked and homebrew? Any tutorials for a newb i havent changed the firmware in like two years and have no idea what to do anymore. Please any help, i looked around but on the sticky it says for 1001 i need a Pandora battery or magic memcard which i have neither of.

Thanks!

EDIT: I was reading some more and im wondering which firmware should i upgrade to?

6.39 PRO-B7
(L)CFW 6.39 ME-6 fix
or another

Again these are just the ones i noticed but i still have no idea how to go about going from my firm to this.
