How to make a PSP magic memory stick?

I bricked my PSP and need a Pandora Battery/magic memory stick - Buy one? Make one?

• So I bricked my psp while trying to update it to the most current firmware... (the battery fell out..) I've recently been told about these things called pandora batteries and magic memory sticks. I've heard they can be bought and also made. The batteries are relatively cheap so Ill probably just buy one, but the memory sticks are pretty expensive. I have a spare 2GB memory stick for the PSP, so how hard would it be for me to make a "magic memory stick" from this? Also if I do make one, is it permanent? Thanks in advance!

• Answer:

  Buy one ***** if ƳƟǘ make one there's à 100 percent chance that it might go corrupt and you'll never use that stick again
