Cant turn off my iPhone - Not shown on Force Quit
I have been installing the IOS for my iPhone 6 and it pops up with an error (14). I am then promoted to update my phone and I won'y lose my apps and general contents especially my phone numbers. I did that and it won't action. I then see that its best to restart (quit iTunes),my computer and phone. It won't do that either. All I have now if is my mobile is stuck during the installation of the new IOS. Cant do anything because The phone is locked into this update mode displaying a connection cable to advise me to connect the phone into iTunes.
Is there anyway I can shut down and have a clean restart of the phone without losing content.
Hope there's some good news out there?
Thanks in advance
