Update: Fixed! Jumped the battery at the battery terminals under the back cover! Badass phone! Simple and beautiful, much like this rom!!
That's how I did it when my battery was run down and I was stuck in fastboot. Now I have a dedicated USB cable just for that reason. I tried making a moto factory cable but don't have the soldering equipment to do so.
Was as easy as jumping a car lol. But I can understand the fear of doing it this way, can easily short out the battery or whole phone if not careful.
