If you can't update wirelessly on your device, you can update manually using iTunes on a computer that you trust.
Before you update
- Back up your device using iCloud or your computer.
- If you have a Mac, check that your computer is running macOS Mojave or earlier. Using a Mac with macOS Catalina or later? Update your device using the Finder instead. If you're not sure which macOS you have, you can find out which macOS your Mac is using.
- If your computer is using Personal Hotspot on the device that you're updating, connect your computer to a different Wi-Fi or Ethernet network before you update.
