I had to rsd lite my phone back to factory default and then was able to take the ota with no problems. I tried to do it on a rooted stock rom but the update just kept taking me to TWRP and then stop. So I had to just reboot and do the whole rsd lite deal. Some people have gone back to factory default from using the tool kit but I never went that route.
