okay so anywho's I have a psp fat cfw 3.52. I'm planning to get a psp slim. here's the dilemma. I want to make a pandora's battery for psp slim. the problem is, is that I use pandora's GUI for making the battery. Now I went to the psp slim/light tab, and did EVERYTHING it told me to. now the problem is, is that when I made it, I wanna put it in the psp slim. HERE'S THE BIG DILEMMA: I have to trade my fat psp for the slim. so after I leave the store with my psp slim I wanna know that this will definatly work. cause when I boot up the psp fat after I made the pandora's battery, it's a blank screen. I know that if you supposidly hit x at the blank screen, it's suppossed to put the psp to 3.xx m33 firmware. what do I do here?
