Always a risk when you are altering an electronic gadgets firmware.
However, the methods around at the moment are pretty bullet proof and work 99.9% of the time when followed to the letter.
I use this one to make my Magic Sticks
YouTube - Install Pandora's Battery Without 1.50orCFW (SLIM+FAT PSP)
Don't hard mod your battery like in the video, either buy a Datel one of Ebay or use **Hellcats Pandoras battery programme. (**Need a PSP on CFW)
My recommendation is to find a mate or local that has a verified working Pandoras battery and Magic Stick and use them to upgrade your firmware.
