So I followed these instructions here: http://androidforums.com/droid-all-things-root/141116-guide-rooting-2-2-windows-linux.html I did the RSD lite to put on the SP Recovery. Rebooted the phone, and it said "Low Battery 0%", I pulled the battery out and booted into the System Recovery. Put on the update.zip file, installed the update, and rebooted. It is still saying "Low battery 0%" and the system keeps force closing. When I try and go back to recovery mode I can't even mount the SD card. I have no idea what to do at this point.
