An unknown error occurred (3014)
I've been trying to upgrade my iPhone 5S from 9.0.2 to 9.1, but every time to try to upgrade via iTunes on my laptop (windows 10 64-bit), I get:
The iPhone xxx could not be updated. An unknown error occurred (3014)
If I try to update the iPhone from "settings/general/software update/download and install" the iPhone pauses, the screen flashes and the settings app disappears.
I have successfully updated an iPad between the same software versions on the same network and I believe I have the latest version of iTunes.
I've followed the advice on similar posts, but nothing changes - any suggestions would be welcome.
iPhone 5s, iOS 9.0.1
