I acquired a handset..but it has the demo software on it.  Anyway to update it so I can use the phones full functions?

Is there anyway to flash it to the current firmware? The hardware is the same so I don't see why I can't update it.

Found the solution! and of all places it was after talking to a t-mobile rep lol

To master reset the Nokia Lumia 810 (at-least t-mobile branded)

1. Power off your phone.

2. Push these buttons in order (a, then b, then c, then d)

    a. Up Volume rocker

    b. Down Volume rocker

    c. Power

    d. Down Volume rocker

You will get an exclamation mark...restart the phone.  It'll show the cogs working..then you're restored to factory firmware and you can set up your accounts now! no more demo phone!

I just downloaded the new update and withing 20 minutes my phone shut down 2 times. When is Nokia going to fox this piece of **bleep** phone?
