Software Update Failed Situations And Solutions:

If you fail to update the iOS 11 on iPhone/iPad over the air, you can
update your iDevice via iTunes. It is easy and very convenient to do an update via iTunes as well.
“Unable to Verify Update. iOS 11 failed verification because you are no longer connected to the internet.”
Sometimes this happens because your Wi-Fi network or cellular network is weak. Try to disconnect the network and reconnect to see if it works. If it is still weak, you can connect another Wi-Fi with strong signal.
“Unable to Check for Update. An error occurred while checking for a software update.”
First of all, you can visit
Apple System Status page to see if it is caused by Apple server. If Apple System Status shows yellow, it means there is something wrong with this server for the moment; You can do nothing but wait. If all servers show green, it means they all work OK and your issue has nothing to do with the server. At that time, you can check if it is due to unstable internet connection. To check this, you can run a speed test before checking for update. It is better to have a stable and fast network connection when updating.
“Software Update Failed. An error occurred downloading iOS 11.”
Under such circumstance, you should check if your iPhone/iPad storage is large enough for you to download this software.

If it has nothing to do with the storage, you can uninstall or delete the previous failed mission while downloading and then reinstall iOS 11 again.
“Can’t Download Update. There is not enough available storage to download iOS 11. You can manage your storage in Settings.”
In this situation, you can delete some apps or files not so important or necessary to you. Or you can delete temporarily saved files on your device to free up some space. No matter which method you choose, don’t forget to pay attention to the file size you should free up. You can go to Settings > General > Storage & iCloud Usage > Manage Storage to see how much space a certain app occupies.
