Hi i have had 3 psp's and i modded them all using tutorials from this website. but last time i had a psp was a good year ago and had to sell it but now i have a new white one with firmware of 5.02. i am wanting to put custom firmware on and not sure how to anymore was wondering what i will have to do. possibly use Pandora battery to downgrade it to 1.50 then upgrade it to a custom firmware any suggestions will be a lot of help thank you very much.
