Before you know how to revert iPhone to older iOS versions, it's important to consider the following things:

* Automatically scan out the supported iOS version for your iPhone for you to choose.
* Fix various iPhone system errors to normal without data loss.

How to roll back the iOS update as you want?
1. Install iOS Downgrade on your computer.
Download and install the software on your computer. Then run it and select iOS System Recovery from the main interface.
2. Connect your iPhone to the computer.
Plug your iPhone into the computer via a USB cable. If required, tap the Trust button on your iPhone. Next, tap Start on the interface and pick the Standard Mode when you reach the configuration screen. After that, hit the Optimize button, and the software will automatically match the device information. If needed, modify the information to the correct ones.

The software will display all the supported iOS versions on the interface. Select the version you want to downgrade to and hit the Next button to download the firmware and downgrade your iOS version.
iTunes is an excellent tool to roll back a public beta version on your iPhone. To do this, first, you need to boot your device in Recovery mode. Second, you need to restore your iPhone with the latest version of iTunes. However, note that this method will wipe out all the existing data on your iPhone, and you will lose data if there is no previous backup file.
What's worse, even if you have backed up your iPhone before downgrading the iOS version, you cannot restore the backup file from a higher iOS version to a downgraded iOS version after that.
Therefore, if you don't mind the complex operation and data loss, you can give it a try.
