Part 2: 10 Best Ways to Fix Cannot Update or Install iOS 18 Issue [FREE]

If you want to upgrade to iOS 18 but only show iOS 17.7, restarting your iPhone or iPad might fix the issue. If your iPhone fails to update to iOS 18, you can take several steps to troubleshoot and resolve the issue. The following guide will help you address the problem:

• 1. Check Device Compatibility
• 2. Check Available Storage
• 3. Connect to stable Wi-Fi
• 4. Charge your device
• 5. Restart your iPhone
• 6. Remove iOS 18 Beta Version
• 7. Delete and Reinstall the iOS 18
• 8. Try updating via iTunes/Finder
• 9. Reset Network Settings
• 10. iOS18 Temporarily Unavailable

1. Make sure your iPhone supports iOS 18

Ensure that your iPhone model is compatible with iOS 18. Apple typically drops support for older devices with each major update. You can check the list of supported devices on Apple's official website.

2. Ensure sufficient storage space

iOS updates require a significant amount of free space. If your iPhone is low on storage, the update may fail. Check how much free space you have.

• Go to Settings > General > iPhone Storage and check available storage.
• You need at least 10GB of free space to install the iOS 18 update.
• Delete unnecessary files, apps, or photos if needed.

3. Connect to stable Wi-Fi

Ensure you're connected to a stable Wi-Fi network (not cellular data) since large updates like iOS 18 require Wi-Fi for downloading. Try restarting your Wi-Fi router or connecting to a different Wi-Fi network if you experience connectivity issues.

4. Charge your device

The update to iOS 18 may take a longer time, and insufficient battery power can also cause the update to fail. Your iPhone's battery should be at least 50%, or you should charge your iPhone while updating to iOS 18.

5. Restart your iPhone

A simple restart can fix many issues, including software update problems.

• To restart, press and hold the Side Button and either Volume Button until the power slider appears.
• Drag it to turn off the device, then press and hold the Side Button again to turn it back on.

6. Remove iOS 18 Beta Version

Deleting the iOS 18 beta will not automatically downgrade your iOS version. You need to update to the official release of iOS 18 or restore your device to completely remove the beta version.

To remove the iOS 18 Beta Profile from your iPhone, follow these steps:

• Go to Settings > General > VPN & Device Management.
• Tap on the iOS 18 Beta Software Profile.
• Select "Remove Profile" and confirm.

7. Delete and Reinstall the iOS 18

If you’re having trouble with the iOS 18 update, deleting and reinstalling the update file can help resolve issues where the update is failing to install or verify. This process allows you to remove a potentially corrupted or stuck update file and download a fresh copy.

• Go to Settings > General > iPhone Storage.
• Scroll through the list of apps and locate the iOS 18 update file.
• Tap on the iOS 18 update file and Tap "Delete Update". Confirm when prompted.
• After deleting, Go to Settings > General > Software Update.
• Tap "Download and Install" to re-download the update file.

8. Try updating via iTunes/Finder

If you're having trouble updating over-the-air (OTA), you can try updating via a computer using iTunes (Windows) or Finder (macOS). Here are the steps to update your iPhone to iOS 18 using iTunes or Finder:

• Connect your iPhone to your computer.
• Open iTunes or Finder and select your device.
• Click Check for Update and then click Download and Update if an update is available.
• Your iPhone will restart once the update is complete.

9. Reset Network Settings

Resetting network settings can often resolve connectivity issues and may help if you're having trouble updating iOS 18. This will remove saved Wi-Fi networks and passwords, so be sure to reconnect to your Wi-Fi afterward.

• Open the Settings app on your iPhone.
• Scroll down and tap on "General".
• Scroll to the bottom and tap on "Transfer or Reset iPhone".
• Tap on "Reset" > "Reset Network Settings".
• Enter your iPhone's passcode.

10. Temporary iOS Software Issue

If the iOS 18 update still does not appear, wait a few hours and try again. Apple's servers can get overwhelmed when a new iOS version is released. Sometimes, there may be temporary server issues or delays.

If you're still having issues after trying these steps, you may need to contact Apple Support for further assistance. It's also worth noting that sometimes update servers get overloaded when a new iOS version is released, so waiting a bit and trying again later can help.
