Like others have pointed out, I used
this guide to create my pandora battery and then reverting it back to a regular battery. All you need is patience to open the battery without mangling its case (or worse, a finger). Be aware though, that the trace on the battery board is pretty much hair-thin, so at first you might have an 'oh crap.. it looked A LOT bigger in that picture' moment when you open it. However, it's easy to do and fixing it with a mechanical pencil only takes a second.
Once you're done with the procedure on that guide you will have 3.71 M33 installed and from there on YOU'RE FREE.
