So my sister gives me her psp and tells me to fix it. I dont really know what is wrong with it but every time it boots up to the xmb it freezes and shuts down. I thought maybe the battery but i tried her battery on my psp and it worked perfect. And right now when i try to boot it up to the XMB the screen doesnt even turn on. the memstick light filckers(no memstick is currently inserted) and the green power light comes on. but nothing else seems to work. I am thinking it is a potential brick or there is somthing wrong with the INSIDE of her psp. BTW she is at a OFW from back in january i think so i cant boot into a recovery with her psp. Thanks!
