My name is***** am sorry to hear that you are having this issue.
I will be glad to assist you with this.
You can reply to me here by typing in the box below please.
Try these steps please.
Disconnect the iPhone, > Hold the home button and the power button down for about 20 seconds or until the Apple logo appears on the screen, then release both buttons.
After it reboots, open your iPhone home screen.-- Connect USB cord to iPhone-- Click "Trust"-- Resume syncing
The best option will be to use a screen connect remote session so that I can connect to your computer directly and troubleshoot this for you.
I will send you the info.
