After downloading the Windows Phone 8.1 GDR1 update and trying to install it, the phone rebooted and now all it does is show the "NOKIA" screen then it goes to the spinning gears for a few, and it shuts down again. Note that it's not the "infinite spinning gears"; these appear for a moment, then the phone will shut off by itself. Everytime I try to boot it up, it does the same thing. I have no idea what went wrong here. Did I break it? Is it bricked? How do I fix it? o.o
Edit: Forgot to add my device is a Lumia 520.
