The “Unable to Verify Update” has been plagued by many and is a known issue for when updating to the latest iOS version, and it could happen to those who are planning to update to iOS 9.3. This latest update, as with other upgrades to Apple’s mobile operating system, is completely free of charge. It can be downloaded to compatible devices and servers can get piled up as people would want to install it at the same time. For the most part, it should be easy to install, but the aforementioned error can appear. For the good news (kind of) is that the error has been known for years and that the fix is still the same, even for this update.
How to Avoid Getting an Error When Updating to the iOS 9.3
Before you start updating to the iOS 9.3, you have to make sure that your device is connected to the Internet. Ignore the Wi-Fi symbol, but do open up Safari and try to load a web page to make sure. If this works, then the device is indeed connected to the Internet. If it does not work, then try to toggle the Wi-Fi connection from your Apple device on and off. If necessary, reboot your device.
Also, make sure that the device is connected on a regular home network. There are some company Wi-Fi networks and hotspots that can filter out the connection to Apple servers. After you have made sure that the device is connected to the Internet, the first thing to do to update to the Apple iOS 9.3 is to shut down the Settings app. To do this, just double tap on the home button then swipe up on the Settings app until it disappears from view.
After closing the Settings app, go back to the Home screen and tap the Settings app once more, then go to General, then Software Update to install said patch. If doing this does not fix the problem, try refreshing the device’s memory.
To do this, press and hold the power button until the “Slide to power off” command appears. Then, press and hold the home button until the home screen refreshes. Once done, try and update once more.
There are also times when the network is at fault when trying to update to iOS 9.3. To make sure that you’re on a stable Internet connection, turn your router off for about a minute then turn it back on afterwards to refresh the connection. If you don’t have your device to automatically connect to the home network, you will have to input the password all over again. After that’s done, do try and downloading the patch once more.
