Just an update, it is 14946.1000 so i will post in the new thread....tried a reboot after using it all day......not looking good, blue Windows LOGO going on and off for 15 minutes so far......
I'm having the same issue. I got the Blue logo bug when I updated my phone to build 14946. Then I had to user WDRT to resolve the issue. I been using my phone for about a week with no issues and the phone just did a random reboot on it's on and it's stuck at the blue logo screen again. I think this build might have a major bug in it. And this is happening on the Lumia 950.
I've gone down the same route - restored to Release Preview via WDRT. Hanging on the blue logo seems to be a definite bug which I've reported in the feedback app
