I have just downloaded the brand new OS update on my Lumia 520 and now it's dead! How can I revive this?

[WPCentral Question]

I have just downloaded brand new os update on my lumia 520.

After reboot, my screen flickered, switched off and now its dead, dead, dead. Is my phone repairable!?

Did you try the soft reset or hard reset button combo?
