Nokia Lumia 520 users: Post your GDR3 status here

On the gears, Were stuck on "100% preparing for installing" for a while though.

Update 1: Just escaped the gears \(*^*)/ now on migrating data.
Update 2: I'm in!
Same experience I had. I thought I had problems at first but finally just walked away and left it alone and when I came back it was done.
