A stuck update can be frustrating, but there are a few steps you can take to resolve the issue. Here's what you can try:
1. Restart your device: Often, a simple restart can fix many software-related issues. Press and hold the power button until the power-off slider appears, then slide it to power off. After a few seconds, press and hold the power button again to turn it back on.
2. Check your internet connection: A stable and reliable internet connection is crucial for downloading updates. Verify that your Wi-Fi or cellular data is working properly. If you're on Wi-Fi, try switching to cellular data or vice versa to see if that makes a difference.
3. Clear cache and temporary files: Sometimes, cache and temporary files can interfere with the update process. On iOS devices, go to Settings > Safari > Clear History and Website Data. Additionally, you can clear app cache by going to Settings > General > iPhone/iPad Storage, selecting an app, and offloading or deleting it. Keep in mind that offloading an app removes its data but retains the icon and settings.
4. Reset network settings: Resetting your network settings can often resolve connectivity issues. Go to Settings > General > Reset > Reset Network Settings. Note that this will remove all saved Wi-Fi passwords and configure network settings back to default.
5. Install the update manually: If the above steps didn't work, you can try installing the update manually using iTunes or Finder on a computer. Connect your device to the computer, open iTunes (Windows) or Finder (Mac), select your device, and click "Check for Update" while holding the Option (Mac) or Shift (Windows) key. Then, select the downloaded iOS update file and follow the instructions to complete the installation.
Remember, it's essential to have a backup of your data before attempting any troubleshooting steps, as updates can sometimes cause data loss. If you're still unable to resolve the issue, it's advisable to contact Apple Support or visit an authorized service center for further assistance.
