How to install iOS software on this iPhone iPad

As of my knowledge cutoff date in September 2021, iOS 13.4 is an older version of iOS. If your iPad is compatible with iOS 13.4, you can install it by following these steps:

1. Check Compatibility: First, ensure that your iPad model is compatible with iOS 13.4. iOS 13.4 is compatible with the following iPad models:

• • iPad Pro (all models)
  • iPad Air 2 and later
  • iPad 5th generation and later
  • iPad mini 4 and later

1. Backup Your Data: Before performing any major software update, it is essential to back up your iPad's data to prevent data loss. You can back up your iPad using iCloud or iTunes on your computer.
2. Connect to Wi-Fi: Make sure your iPad is connected to a Wi-Fi network. OTA (Over-the-Air) updates require a stable internet connection.
3. Access Settings: Open the "Settings" app on your iPad.
4. Go to General: Scroll down and tap on "General."
5. Software Update: Under the "General" section, tap on "Software Update."
6. Download and Install: Your iPad will check for available updates. If iOS 13.4 is available, you will see it listed. Tap on "Download and Install."
7. Enter Passcode: If your iPad has a passcode, enter it to proceed.
8. Agree to Terms and Conditions: Review the terms and conditions and tap "Agree" to continue.
9. Start the Update: The download and installation process will begin. The time it takes to complete the update may vary depending on your internet speed and the device's performance.
10. Restart: After the update is downloaded and installed, your iPad will restart, and you will be running iOS 13.4.

Please note that software updates beyond iOS 13.4 might be available at the time you attempt to update your iPad. Apple regularly releases newer versions of iOS with additional features, improvements, and security updates. You might consider updating to the latest available version of iOS for the best user experience and security.

As of my knowledge cutoff date, the latest iOS version was iOS 15. Be sure to check for the latest iOS version available for your iPad model by going to "Settings" > "General" > "Software Update." If a newer version is available, you can choose to update to that version instead.
