yes you can but you can only with a Pandora Battery and a Magic Memory Stick, btw if you would like me to i can do it for you, i just ask that you pay shipping both ways. And if you'd like to make a small donation you can, but ill do it for free and if you want to you can send me your battery or memory stick or both for me to convert but i dont need them i can use my own stuff to put on any custom firmware thats out

just find a universal unbricker file thingy google it, i use it to downgrade and install cfw on my friends' psp. fat and slim. just follow the on screen instructions and use pandora after

edit: my friend's psp was 4.01 ofw and it worked btw and the file online is about 231 megs i think, if its less then 200, then its not the same one i have
