I ran into this slide to upgrade bug twice. I updated my. 5S OTA (from 7.1.2) and it occurred. A forced restart actually allowed me to get past it. Then I did a reset all setting later and the reset got stuck at about 10%. The only way out of this was a dfu restore through iTunes. Of course I'd been hanging on to iTunes 11.x so I had to update that to 12.x (bugger, I liked the old interface). I set up as new then restored my backup from the previous night (a 7.1.2 backup) and the slide to upgrade bug reoccurred. Forced restart got me past and I'm not game to try the reset all settings option again. Hopefully a 7.0.1 update is released ASAP for this one. I pity those who didn't back up first or don't have a computer with iTunes installed to help out.
If this is related to ios 7 users updating I'm not surprised if it didn't show up in beta testing. How many beta testers would have been holdouts to ios 7? Most would surely have been early adopters who already updated to 8.x wouldn't they?
