"The iPhone "iPhone" could not be updated. An unknown error occurred (6)."

Did you come across a similar message? Many iPhone users report error 6 when they try to update or restore their iOS device with iTunes. This error can be caused due to outdated iTunes version, damaged hardware, virus, or incompatible applications. It can occur in iPhone devices like iPhone 6, iPhone 6s and, iPhone 4.

This page discusses some simple methods you can use to fix the iPhone 6/6s update/restore error 6.

Step 1: Right click on the anti-virus icon and disable it.

Step 2: Update the iOS version of your iPhone again.

If the update was successful, you should replace, upgrade or keep the anti-virus disabled.
