Question: Iphone disconnected problem during backup
I have a problem when I am trying to make a backup of my Iphone 7 and iTunes via USB cable - Iphone disconnected problem - "iTunes could not back up the iPhone because the iPhone disconnected". I cannot backup to my computer. In the same time, Wi-fi backuping to iCloud was completed succesfully.
I am using latest iOS 10.3.3 and Windows 10x64 (version 1703, build 15063.483) with all updates and latest iTunes 188.8.131.52 and good ASUS motheboard with good powerful USB 3.0 porrts and original Apple USB-ligtning cables.
I tried to use 3 different cable and 4 different USB ports, with no result.
I tried to reinstall everything, I stopped antivirus, activated "At the Plane" mode, and made all other tricks which I found here, with no result.
I had this error with previous versions of iOS and iTunes as well, but when I had iPhone 5, I did not have this error on the same desktop computer.
iPhone 7, iOS 10.3.3, Iphone 7
