Error Occurred Installing iOS 10.3? Here’s the Fix

With the promise of new features and bug fixes, many users are updating to the new iOS 10.3. But just as it is with any iOS update, there are those who are experiencing some problems. The major one being the inability to even install the update. You may have seen a message saying “Unable to Install Update- Error Occurred Installing iOS.”

This is not uncommon error to experience with any iOS update since it occurs due to a huge number of iOS users trying to update 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

01 Reset Network Settings

Since you do need a network connection to update your device, 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.

02 Force Restart the Device

A force restart will work to fix just about any issue you are having with your device. It is therefore a good option to try even when the device fails to update. Press and hold the Power and Home buttons (Volume Down button for iPhone 7) and continue to hold them until you see the Apple Logo.

03 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.

04 Toggle Airplane Mode

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

05 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. Try it, it might just work for you.
