I have a psp slim that I would like to convert to cfw. I also have a pandora battery and a magic memory stick with 3.71M-33 files already installed. Originally, I purchased the pandora battery and the magic memory stick, strickly set up to be use for a psp fat that I also have. I was told that the pandora battery and the magic memory stick was also good to be use on a slim as well. Okay! This is where I have a problem. I took my pandora battery and the magic memory stick and put it in, but nothing happened. Odviously, I was told wrong. Can some one help me out with this. Thanks....
