    how can i put cfw on my fat psp that has 5.03fw?

    i dont have a pandora battery or the magic stick. is there even a way for me to downgrade it without those things? i happened to hear about cfw that you can upgrade to instead of downgrading its on here http://games4psp.net/custom-firmwares can someone tell me how that works.
