Downgrade OnePlus 8/8 Pro from OxygenOS 11 (Android 11) to OxygenOS 10 (Android 10)

Have you installed the latest OxygenOS 11 beta on your OnePlus 8 device? If you’re facing issues and feel that the beta software is not optimal for your daily usage, then you might want to downgrade back to the good old stable OxygenOS 10 software. Moreover, OnePlus has also released the stable OxygenOS 11 update lately. If you’re running the OOS 11 Open Beta, you’d need to downgrade to OOS 10 stable to get the stable OxygenOS 11 OTA update.

In this guide, we will show you how to downgrade the OnePlus 8/OnePlus 8 Pro from OxygenOS 11 (Android 11) Beta to OxygenOS 10 (Android 10). This could be easily done by installing the downgrade/rollback package through the Local Upgrade option.

OnePlus was one of the first few device manufacturers to jump on the Android 11 dev preview bandwagon. Soon after their launch, both the OnePlus 8 and OnePlus 8 Pro received Android 11 developer preview support, aiming at developers and early adopters. And now, after the release of the stable Android 11 update, the company has released Android 11-based OxygenOS 11 Open Beta for the aforementioned devices.

Downgrading Back to Stable OxygenOS 10

So, why would you need/want to downgrade your OnePlus 8/8 Pro to OxygenOS 10?

It’s safe to say that a lot of users would have installed OxygenOS 11 Open Beta on their phones to test the new features since it’s publically available for everybody and is also quite easy to install. What an average phone user might overlook is the fact that this is beta software. It means that it is still under development, might contain bugs, and thus would not be as stable as the regular stable OxygenOS 10 software for daily usage.

Going through the official FAQ thread posted by OnePlus, we did find a lot of users reporting a variety of issues such as faster battery drain, the new Always-on Display feature not working, uncertified device status in Google Play Store, and more.

In our own testing, we didn’t come around any major issues but one. The proximity sensor was not working properly, especially while on a phone call. Since making calls is a primary function of every phone, it could be extremely inconvenient. Apart from that, everything else seemed to be quite well for our use-case.

While some of these issues might have been caused due to the software, there’s a chance that some others could have been caused due to a user-error. Although not mandatory, performing a factory reset after installing OxygenOS 11 Open Beta could resolve most abnormal behavioral issues. It could provide you a good starting point when looking for potential bugs and reporting them. And more efficient feedback from the users would mean faster development and sooner release of the stable OxygenOS update.

That aside, if you strongly feel that the OxygenOS 11 Open Beta software isn’t yet polished enough for your daily usage, then you can downgrade your OnePlus 8/8 Pro back to stable OxygenOS 10 software for a completely stable experience. The process is quite easy and wouldn’t take more than a few minutes of your time. So, without any further ado, let us get to the instructions.

Requirements

Make sure that you fulfill the requirements listed below before you head to the instructions.

• Downgrading by installing the OxygenOS 11 rollback package will automatically erase all the data stored on your OnePlus 8/8 Pro. So, take a complete backup of all your important data first. You could also refer to our guide for instructions on how to take a backup.
• If you’ll be using your computer to download and transfer the files, then ensure that you have the proper OnePlus USB drivers installed. You will not need these drivers if your PC can automatically detect the phone.
• Charge your phone to a sufficient battery level (40% or above) to prevent it from shutting down during the downgrade process.
• If your OnePlus 8 is rooted with Magisk, open Magisk Manager and select “Uninstall” > “Complete Uninstall” before you start following the instructions. This will unroot your phone completely and ensure that that the downgrade goes smoothly.
