Around 3PM today I downloaded and installed the update. MY phone restarted itself and went into an icon with two spinning gears, one larger than the other. I've tried every tutorial on hard resetting and it takes me right back to this same screen. I really really need help fixing this, this is the only phone I own, and since its the Ativ S theres on nowhere I can go to get it fixed or replaced. With out it I could lose my job.
What do I do?
