Nokia Lumia 830 Update bug.

[WPCentral Question]

My Lumia 830 is having problems updating to the newest technical preview build, the first update to 10166 works fine, next I search for more updates to go to 10512 and when I find it, it downloads fine just when it reaches the install with the cogs. It finishes then restarts the process but no loading progress happens and after a few seconds I get an unhappy sideways facing face. then it goes to the nokia splash screen before switching off. This process keeps happening
