iPhone 5S did a sync, but won't stop

[Microman]

I have that double arrows going around in circles and phone or iTunes doesn't give me the option to eject the phone.

Whats up?

Not on 8.2 yet. Running on Lion 10.7.5

iTunes 12.1.0.50

I had that happen to my phone a few times. I had to shut it down and restart the phone then sync again. So far, that has always fixed the issue.

Quit iTunes, restart phone. iTunes did that to my iPod Nano this past weekend.

I have seen the BLUE screen and Logo loop.

Just recently I got black and white bars and logo loop.

The 5s has been a real trial of Faith.

I find that if I manually back up and THEN sync, the problem fixes itself. Usually.
