Answer #3
Okay you have the pandora battery and memory stick?
First take out your current battery and MS.
First put the magic MS in, then the battery.
It should turn on by itself.
Then just follow the onscreen instructions to flash a CFW.
If this doesn’t work, then you will have to use another method…

Have you even got a Magic Memory Stick (as the poster above abbreviated as ‘MS’)?
If not, do a Google search for ‘Magic Memory Stick PSP’ and you’ll find the set of files you’ll need to download to your memory stick. Format it before you place these files on the stick. Then follow the instructions as the other poster said.
