With the promise of new features and bug fixes, many iOS users are updating to the latest iOS 10.3. But just as it is with any iOS update, there are many users who are experiencing some problems. The major one being the inability to install the update. You may have seen a message saying "Unable to Install Update. An error occurred Installing iOS 10.3."
This is not uncommon error to experience with any iOS update even the iOS 11 update since it occurs due to a huge number of iOS users trying to update to new iOS version at the same time. Waiting for a while before trying to update again may work. But if you still face the same problem in a few hours, the following are some solutions that can help.
1 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 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.
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 re-installing the update again to see if it works.
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.
