I just wanted to put this here in case anyone has a low battery and needs to flash. If anyone needs more info/help let me know.
My 'charger' I'm using is nothing more than cutting the end off of a usb cable, stripping the red and black wires bare, and twisting them so the strands are tightly twisted. Then I carefully stick the red into the positive pin slot of the battery and the black into the negative. I then insert the battery into the phone and snap the cover on. Plugging the usb into a charger makes the phone think it's fully charged so I can flash.
