Part 2. 5 Common Troubleshooting Solutions

1. Reset Network Settings

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 13/12/11. 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.

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.
