Moto x 2013 software issue 5.1( active display working but phone not unlocking)

[AC Question]

Now when the phone is booted the initial Moto X animated screen is visible but then it goes into a black screen and the login screen never appears. If I let it sit for a few minutes it will occasionally display the time or a notification (voice message icon, etc) but swiping down does not unlock the phone. It just does a short vibrate and then goes black. Also the battery gets hot when it is left on (while the screen is black). Plugging the phone into the computer is not recognized as an external drive (probably because it doesn't boot properly). I tried booting in fastboot mode, recovery, then to wipe the partition cache (twice already) and it still does not properly boot.
