So, I was updating my friends Lumia 900 through Zune as I have done before with all my windows phones. I know for a fact, that she has not updated the phone at all since she bought it at launch. So after the photos she had on there synched, it wouldn't update. Saying that there was no update available. Which I know is not true, she is on firmware 7.10.8112.7. I tried to factory restore, and the same thing happened. I tried the turn off the internet trick that I used to update my Focus to Mango with, and nothing. Any suggestions?
