Roll Back iOS Update Manually

In this section, you will learn every step required to roll back an IOS version manually. First, make a full backup of your iOS device via iTunes. Afterward, downgrade through either iTunes or the recovery mode.

1: Make a Backup to Avoid Data Loss

Regardless of how you downgrade your iOS device (whether through iTunes or a third-party app), the process will erase data that is yet to be synced with either iCloud or iTunes. So we always recommend you make a full backup of your device before rolling back to a previous iOS version. This section explains how to back up your iPhone to iTunes.

  • Open iTunes on your Mac or Windows computer.

  • Connect your iPhone to the computer with a USB data transfer cable.

  • Navigate to your device information page.


  • On your iPhone device, tap Trust if you haven't trusted your device with the computer before.

  • Under the Automatically Back Up tab, choose the This Computer Afterward, click Back Up Now.

  • If you wish, you may encrypt the backup by ticking the option that says Encrypt Local Back Up. Choose a backup password and proceed with the process. Encrypting your backup is recommended because the backup file carries saved passwords, health data, website history, Wi-Fi settings, and many more personal information.

  • Wait for the backup process to complete.
