Part 2. 5 Common Troubleshooting Solutions

1 Reset Network Settings

Since you do need a network connection to update your iOS, an errant network connection could be causing the problem. Go to Settings > General > Reset > Reset Network Settings to reset the network and see if this works.

2 Force Restart the Device

A force restart will work to fix lots of issues you are having with your iOS device running different iOS versions including iOS 14/13/12. It is, therefore, a good option to try even when the device fails to update. Press and hold the Power and Home (Volume Down button for iPhone 7) buttons and continue to hold them until you see the Apple Logo.

 Force Restart the Device

3 Close the Settings App

If you are still having the same problem even after a force restart, try refreshing the settings app. To do this double-tap on the Home button and swipe the Settings app out of view. Try reinstalling the update again to see if it works.

 Close the Settings App

4 Toggle Airplane Mode

Because updating requires a network, toggling Airplane mode on and then off may help fix network issues you may have and allow you to update. To do this go to Settings > Airplane Mode and turn it on. Switch off the device for about 10 seconds and then turn it back on. Disable Airplane mode and then re-try the update.

5 Turn off Wi-Fi and Switch to Cellular Data

We're not sure why but some people found that if they switched from Wi-Fi to Cellular data, the update works just fine. So try this method, it might just work for you.

 Turn off Wi-Fi and Switch to Cellular Data

Apple will release iOS update often. The best way to avoid problems with one update might be waiting for the more stable version. But if you cannot wait any more, then use iMyFone Fixppo iOS System Recovery (compatible with iOS 14/13/12/11).
