This worked like a charm. I had a one x lying around not being used, so I thought I'd give this method a shot. I installed weaksauce, and thought it wasn't holding root upon reboot. I just had to wait it out for 15 seconds, and I would see the bluetooth icon flash on the status bar, and then I would see a message "Root Activated". Rumrummer failed the first time, but went all the way through on the second pass.
Thanks for the tutorial!
