If you have an old fat custom firmware PSP you can download some small software into the fat psp so that you can create the pandora battery without any soldering. Then create the necessary magic memory files and once your done with that you insert the memory stick with the magic memroy files into the Slim psp and then insert the pandora battery and it should start up with the instalation for the custom firmware.
You can find a detailed guide somewhere in
AfterDawn.com I'd look for it but i'm not at home right now. But you wont need to solder your battery if you have a fat cfw psp.
other than that, has anyone tried out the new 3.80m33 firmware.

I'm going to try it when I get home so I'm hoping that the remote play has been fixed without entering any other files into the system.
Jam it back in, in the dark.
