Did you en up fixing this? Mine is boot looped, but goes red-green-blue during each iteration.
Mine is stock and the 16.2 update made mine do the red blue colors at start up and once booted it didn't want to connect up with anything. I did a factory reset and it started better but kept shutting itself off and restating the set up process. Each reboot it would get further aong and finally it completed and it's working fine now.
