UPDATE 2021-03-15 12:15 IST:
OnePlus added EU rollback links as well, and we've updated the article to reflect this.
OnePlus 8T was released on 14th October 2020, and came with OxygenOS 11 out of the box. Its Closed Beta program started in December 2020, meaning it's been 3 whole months for the so-called "alpha" builds to be tested by the chosen 200. Now it's finally time for Open Beta to begin, and here's the changelog:
Open Beta 1 changelog
- Optimized the UI display of the status bar
- Optimized the stability of the frame rate and improve its experience while playing games
- Optimized the Community homepage with more noticeable notification
- Updated Android security patch to 2021.02
- Optimized the animations of sunny and cloudy days for a clearer dynamic display
- Optimized the layout of the cloud service in the Gallery for a better operation experience
It's not an interesting first build (even the security patch is 1 month old), but over time we're sure there would be more features added. Their software schedule guarantees one Open Beta update every month, which usually means security patches are more up-to-date than the stable track. Note that while there are advantages in switching to Open Beta, you should understand the risks involved, given that it's a beta. Also remember that you expected to report bugs to OnePlus directly, and that switching back to stable at any point will most likely require a full data wipe. So don't get excited and jump into OB1 without considering all its pros and cons.
Which devices support Open Beta 1?
- OnePlus 8T (all variants except carrier-branded e.g. TMO)
OnePlus claims that beta builds for EU & global are now merged, which is good. Indian builds still remain separate, and of course the app already has both builds.
Where can I install OB1?
This is meant only for 8T devices - it WILL NOT WORK for other devices. Since this is a beta update, make sure to backup all important data before your proceed as it may not be stable!
Before installing, please ensure your battery level is at least 30% and you have at least 3GB space left on your device. If you encounter any bugs in OB1, make sure you report them to OnePlus.
You can install the beta using this app itself: close this article, open the app's settings, and switch to the "Open Beta (full)" update method - you might have to enable "Advanced mode" as well. Then go back to the main screen of the app, and you'll be able to download OB1. You can check the forum thread listed below for more information:
Can I revert to the stable version of OxygenOS?
Yes, please read the forum thread of your device as linked above for detailed instructions. Rolling back will completely wipe all your data, so please take a backup before proceeding.
Below are the rollback/downgrade packages for each 8T device. Make sure you choose the correct rollback package for your device and region. We are providing these links purely for your convenience, as rolling back isn't natively supported by our app. After downloading the correct rollback package, move the file from the "Downloads" directory to the topmost directory of internal storage (the same directory that the "Downloads" folder is in). Then, open Settings -> System -> System updates -> cog icon in the top right -> Local Upgrade, and choose the rollback package.
The following packages will rollback your device to OxygenOS 126.96.36.199/8 (following regions), and will wipe all your data.
Remember: these are rollback packages - they're not the packages you should download if you're looking to switch to Open Beta. For that, close this news article and change your update method to "Open Beta (full)" in the app's settings, and enable advanced mode as well.
Please take great care in downloading the rollback package meant ONLY for your specific device and region.
