[How to Fix] Unable to Install iOS 17 Update

Now, iOS 17 is released to everyone, so you don't have to worry that you don't have a developer account to install iOS 17 Beta. However, some users reported that they received an alert saying "Unable to Install Update. An error occurred installing iOS 17." This error might come from incompatibility, poor Internet connection, insufficient storage, system problems, etc. To help you deal with these kinds of problems, we test many methods and collect viable solutions for you. Thus, if your iPhone or iPad is not able to update to iOS 17 or iPadOS 17, or your older devices are unable to install the latest system version, read this article and follow the solutions one by one.

unable to install update

Solution 1. Check Compatibility and Restart iPhone/ iPad

The simplest and most overlooked point is the compatibility of the device with the system. Since not all Apple devices support updating to iOS 17, you need to be aware and check if your device is compatible with iOS 17 when prompted with the message Unable to Install Update. Up to now, iOS 17 can be installed on iPhone XS and later. If your device is compatible with it but the error message still appears, try restarting your iPhone and reinstalling it.

Solution 2. Check/ Reset Network and Try Again Later

Some users may receive the message showing "Unable to Install Update. Software update requires a network connection." If the network you connect to is weak, the process of installing iOS 17 update will be slow or even be paused. So, once you are unable to install update on your iPhone or iPad, check the network by disabling and reenabling Wi-Fi, forgetting and reconnecting to a stable network, turning on cellular, and closing VPN. Or, you can go further by resetting the network settings on your device. Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings, and confirm your action. After that, you could try to update to iOS 17 again.

Solution 3. Free Up More Space for Installing Update

As the new operating system will consume a lot of memory space, before upgrading, you not only need to back up your data but also make sure that your iPhone has enough storage. Hence, head to Settings, tap General, scroll to iPhone Storage, and see if there are more than 5 GB left on your device. In case there is no more space to install iOS 17 update, you could delete some unimportant data or apps to get more storage.

Solution 4. Delete and Install iOS 17 Update Again

Once the iOS 17 profile is successfully downloaded on your iPhone or iPad but is unable to be installed, this error could be fixed by repeating the whole updating progress. To achieve this, you are required to go to Settings → General → iPhone Storage → iOS 17 → Delete Update. As long as the faulty profile is deleted, you could go back to check for update and tap Download and Install to reinstall iOS 17 update.
