Okay, I know hot to make a Pandora Battery to downgrade a PSP wich is running a Custom Firmware to version 1.50 (for example from 3.90 M33 - 3 to 1.50). To downgrade you need to make a Magic Memory Stick but that's something else.
You can also use the Pandora Battery to make some changes to your PSP or to install programs (for example Dark Alex's Time Machine)
Okay, if you want to create a Pandorea Battery simply open your battery using a knife or something small and sharp. Then take of the black plastic piece because it's having no use right now. After this take the green piece and cut a line. Then put back the black thing and close the baterry (everything must be exactly like it was before). You can use some tape to close the battery but don't use to much because then it won't enter in the battery slot (it will be to big).
And that's all. You have your own Pandora Battery. You can look on youtube for more info. I sugest you to buy another battery and not to do this on your original battery because you may not be able to make it again normal. To make it normal you just have to draw a line with the pencil instead the line you cut. It's better to have to batteries: a normal one and a Pandora one.
