“I waited until today hoping to avoid the problem of too many people upgrading at the same time. Tried to upgrade my iPad Air 2 today - failed three times so far through iTunes and twice OTA. It shows “Software Update Failed” al the time. I guess I'm just out-of-luck.”

Since iOS 11 is coming this fall, it’s likely that many users would meet the problem of “Software Update Failed” error when they try to install the latest iOS 11 on iPhone/iPad. Maybe the Apple servers just can’t handle the level of the traffic, or there are other reasons can cause this error like limited storage, virus attack, system crashes and etc. Here we collected several troubleshooting methods to help you fix the “Software Update Failed” error as simple as possible.
Try to download the iOS 11 via iTunes on your computer instead of via Apple’s OTA servers. This way works well most of the time, but you’d better update your iTunes to the latest version before start.
Once the iOS 11 is released to the public, millions of Apple users would get the notice and try to install it immediately. So you may not be able to connect to Apple’s server at this time.
You can reboot your Wi-Fi rooter and make sure your Internet connection is working well. Go to Settings > General > Reset > Reset Network Settings. Tap on “Download and Install” a few minutes later.
When you get the notice saying “An error occurred downloading iOS 11”, just close the messages and force restart your iPhone or iPad. You may be disconnecting to the Apple’s server when there is huge amount of traffic at the same time.
There are chances that your iPhone or iPad is out of storage so that the iOS 11 can’t be installed properly. Just delete some useless data and create more space for your new iOS version.

2. Connect device to computer and run iTunes > Summary.
3. Hold the Shift key on Windows PC or Alt/Option key on Mac and click the “Restore iPhone” button.
4. Preview and select the iOS 11 IPSW file downloaded earlier.
