Windows Phone 8.1 Lumia 1520

[WPCentral Question]

I have a Lumia 1520 with 8.1 dev preview, and my phone just restarted and doesn't respond, it just show only Window button light.

Any help?

Have you tried a soft reset? Hold the power button and Volume Down simultaneously until you feel the phone vibrate.
