OK i made a jigkick battery but soldering off the pin which is ilustrated in the benheck.com forum. Then i tried the battery , It worked !!! Automaticaly switches on the PSP with a blank screen, success !!! Now, i bought a 512 Memory Stick PRO DUO and then i formatted my Mem stik then i used the Easy installer to install the apps nd stuff. Then i put in the mem stick first, then the battery , It switches on but the memory stick light doesnt blink nd nothing happens. I NEED HELP !!!! any ideas ?
