I got my white Nokia lumia 920 Sunday and have had no problems out of it......until yesterday. There was an update available yesterday so I tried to update the phone. It had over 50% battery life left and I even placed the Phone on the charger tO update. When I checked on my phone it was completely dead after 10 minutes. I tried charging it but it would not come on after 3 hours of charging. I tried a hard reset and when I did the cog wheels showed up, they would spin for a minute then a frowning emoticon would pop up on my screen and nothing else would happen. What went wrong? I liked the phone alot and I am having it replaced. I would like to know what happened so I can keep it from happening again
