1. Check Available Storage Space
One of the most common reasons for update failures is insufficient storage space on the iPhone. The iOS update package requires a few GBs of free space for download and installation. Before hitting the Download and Install button, go to Settings > General > iPhone Storage to check the available space on your device.
Ideally, your iPhone should have at least 5GB of free storage for the 17.3.1 update to download and install smoothly. If you are low on space, try removing unwanted apps, photos, videos and music to free up storage. You can also offload large apps that you don’t use often – this will remove the app data but keep the app on your phone.
2. Connect to a Stable Wi-Fi Network
The iOS update is quite large in size. Downloading it over cellular data can be slow, consume your monthly data cap and possibly fail. For best results, connect your iPhone to a stable Wi-Fi network before downloading and installing the update.
A weak Wi-Fi signal can cause download failures. Ensure your Wi-Fi router is in close proximity and avoid connecting your iPhone to public hotspots as they tend to have intermittent signals. If possible, disabling other Wi-Fi connected devices can help provide more bandwidth for your iPhone to download the update faster.
3.How to Restart Your iPhone
Before trying to install the update, restart your iPhone. This clears out any cached data and frees up memory which can prevent update issues.
To restart, press and hold the side button and either volume button until the power off slider appears. Drag the slider to turn off your phone. Wait for at least 30 seconds and then press the side button again to turn your iPhone back on. Now retry downloading and installing iOS 17.3.1.
4. How to Check Apple’s System Status Page
Sometimes update failures can simply be due to ongoing issues on Apple’s servers. Check the Apple System Status page to see if there are any active issues or outages with iOS devices or the App Store that may be preventing the 17.3.1 download.
If Apple reports issues with “iOS Software Update” or “App Store” services, it’s best to wait until the problems are resolved. Retrying the update when services are up and running should allow it to install normally.
5. How to Update your iPhone via iTunes or Finder
If you are unable to install the iOS update directly on your iPhone, try updating through iTunes on Windows or Finder on Mac.
Updating via iTunes
- Connect your iPhone to your computer using the USB cable.
- Open iTunes and select your connected iPhone.
- Click on Summary and then Check for Update.
- iTunes will now download and install the latest iOS update on your device.
Updating via Finder
- Connect your iPhone to the computer using the USB cable.
- Open Finder and select your iPhone under Locations in the left sidebar.
- Click on General and then Check for Update.
- The Mac will download and install the update to your connected device.
Updating through iTunes or Finder can often resolve ‘Unable to Verify Update’ and other errors faced when trying to install OTA updates directly on the iPhone.
6. How to Repair your iPhone
If you have tried all of the above solutions but are still unable to install iOS 17.3.1, your last option is to repair your iPhone. Repairing will fix any underlying software issues that may be preventing the update installation.
You can use iTunes or Finder to repair your iPhone:
Repairing via iTunes
- Connect the iPhone to your computer and open iTunes
- Select your device and go to Summary
- Click on Restore iPhone – this will reinstall iOS and wipe your data
- Once the restore is complete, setup your phone from scratch and retry the update
Repairing via Finder
- Connect your iPhone to the computer and open Finder
- Select your phone and go to General
- Click on Restore – this will wipe your device and reinstall iOS
- After restore, configure your device anew and check for the 17.3.1 update
Repairing the iPhone software is usually an effective solution for stubborn iOS update problems. However, it will erase all data so remember to take a backup beforehand.
Specific App Issues after iOS 17.3.1 Update
At times, major iOS updates can cause problems with third-party apps like Spotify, Outlook etc. Here are some tips for fixing app-related problems:
- Check if the app developer has released any update addressing issues with iOS 17.3.1 – install any available updates
- Delete and reinstall the problematic app
