I have a original PSP-2001, with a fully pandora compitable motherboard. I made a pandora MMS on a 4GB memory stick pro duo with psp grader on win7, and i cutted the leg of the batterys controller chip. If i insert the battery it turns on, and i'm holding the L key while inserting battery. Only problem i get is that the backlight turns on but screen keeps being black, the MS indicator flashes very short and then it does nothing else than showing a black screen. Also tried a old 64MB memory stick but then it doesn't even turn on the backlight of the screen, neither a flashing MS indicator. Both memory sticks are compitable with psp and shows up as a magicgate one(it is a magicgate offical memory stick). If i boot up with normal battery and without MS it just turns on and backlight keeps off, no indicators flashing and it turns off after a minute. Before it stopped working i tried to uninstall cfw by removing it from cfw installer, then i rebooted the psp and sience then it's doing nothing Can somebody help me?
