Part 3. 5 Alternative Ways to Fix 'Cannot Update to iOS 18'
There are several alternative approaches you can take when you cannot update to iOS 18.
Solution 1. Free Up Storage Space on Your iPhone
One of the most common reasons iOS 18 won't download is due to insufficient storage space. iOS updates typically require several gigabytes of free space to download and install. If your iPhone is running low on space, the update process may be blocked entirely.
Step 1: Go to Settings > General > iPhone Storage to see how much free space you have.
Step 2: Remove any large files, apps, or media that you no longer need.
Step 3: Use the Offload Unused Apps feature to free up space without losing data.
Step 4: Backup your photos and videos to iCloud or another service and then delete them from your device.
Solution 2. Ensure a Stable Internet Connection
If your iPhone is unable to check for updates or the download is constantly interrupted, it’s likely due to connectivity issues. A strong, stable Wi-Fi connection is essential for a smooth update.
Step 1: Ensure your device is connected to a stable Wi-Fi network rather than using cellular data.
Step 2: Public Wi-Fi networks can be unstable. It's better to use a private, secured connection for such updates.
Step 3: If your signal is weak, try moving closer to the router to improve connection quality.
Solution 3. Check iOS 18 Supported Devices
If you can’t download iOS 18, it’s crucial to ensure that your iPhone is compatible with the update. Apple usually restricts newer iOS versions to devices that meet specific hardware requirements. If your device isn’t on the list of supported models, the update won’t appear, no matter what you try.
Solution 4. Restart Your iPhone
Sometimes, a simple restart can resolve the issue of iOS 18 not updating. Restarting your device can clear temporary glitches and refresh system processes, which might be blocking the update.
Step 1: Press and hold the Side button and either Volume button until the slider appears, then drag it to turn off the device.
Step 2: After it powers down, press and hold the Side button again until the Apple logo appears.
Step 3: Once your iPhone restarts, go to Settings > General > Software Update to see if the iOS 18 update is now available.
Solution 5. Use iTunes/Finder for Updating iOS 18
If you cannot update to iOS 18 directly on your device, using iTunes (on Windows or older macOS versions) or Finder (on macOS Catalina and later) can be an effective alternative. This method allows you to download and install the update via a computer, which can bypass issues related to over-the-air updates.
Step 1: Use a USB cable to connect your iPhone to a Mac or PC. In iTunes, select your device in the top left corner.
Step 2: Click “Summary.”
Step 3: Click “Check for Update.”
Conclusion
Whether it's a lack of storage, an unstable connection, or even an unsupported device, the obstacles can feel overwhelming. Fortunately, with a bit of troubleshooting—like freeing up space, checking compatibility, or even restarting your iPhone—many of these issues can be resolved on your own.
But if you’ve tried these solutions and still cannot update to iOS 18, it’s time to consider a more reliable fix. ReiBoot offers a straightforward, efficient way to cut through the noise and get your iPhone back on track, ensuring that nothing stands between you and the latest iOS experience.
