I have a 512mg Sandisk memory stick that I would like to turn into a magic memory stick. That would install CFW 3.71m-33. I know that this a bit out of date but I accidentally formatted the memory stick and now I'm trying to find an installer program. I have two programs that I have tried out but no luck. One is call Pandora Deluxe that runs right out of windows xp and the other is a homebrew type of program, which also runs from windows xp. The homebrew program I've tried it once before and successfully turn the memory stick into a pandora stick. Now I'm trying it again and no luck. It installs CFW 3.71m-33. Actually, the program automatically did install the files needed into the memory stick but when using it together with the pandora battery, the wifi and the memory stick LED's on the psp did not turn on. The other one is not quite Noob friendly and I wind up getting frustrated. I have also tried out the UPMS program but at no success as well. If any one knows of any other type of program or ways to help me out I would highly appreciate it. Thanks...
