Although you may be hyped by OxygenOS 13 now being available for your device, do remember that this is beta software (as proven by known issues list) and as such, you accept any risks by installing this update. Furthermore, you're expected to report bugs to OnePlus directly by dialing *#800# from the stock phone app. Alternatively, you can also submit feedback via this form. Do also mind that rolling back to OxygenOS 12 at any point will require a full data wipe, so don't get excited and jump into OB1 without considering all its pros and cons.

How can I install this beta?

This is meant only for the Nord CE — 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!

First of all, OnePlus now follows a completely different process for "Open" Beta builds. It started with the Nord 2T, then the Nord CE 2 Lite, Nord CE 2, and Nord CE were also adopted into this process. Earlier, OnePlus used to have a Closed Beta program, in which they selected people based on their form responses. After that, an Open Beta would start, with public download links so that everyone (hence the name "Open") could try it out. However, with the aforementioned devices, they required users to fill out a form and wait for their application to be accepted — which is very clearly similar to the Closed Beta program. Nothing was "Open" about it:

Anyway, OOS13 beta 1's official download link has been captured by some users in the community, so after rigorously verifying it, we've added it to the app so that you can install it if you choose. However, we highly recommend applying via the normal process (described above), so that OnePlus' software & testing teams don't get overwhelmed with more beta testers than they planned for (at the time of writing, as seen in the screenshot above, OnePlus wants to accept only 5000 users).

Before installing, please ensure your battery level is at least 30% and you have at least 5.5GB space left on your device. If you encounter any bugs in OB1, make sure you report them to OnePlus. Also, it's recommend that you're on the latest version of OxygenOS 12 (C.09/C.10) before installing OOS13 OB1. Neither we nor OnePlus are responsible for any issues you may encounter during the installation process.

You can install the beta using this app itself: close this article, open the app's settings, and switch to one of the "Open Beta" 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 for more information: https://community.oneplus.com/thread/1255864653553598467.

Can I revert to the stable version of OxygenOS 12?

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.

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 -> About device -> Version and tap "Build number" 7 times. This will enable Android's built-in "developer mode" (you might have to enter your phone's PIN/password too). Once this is done, "Local install" will once again be visible in Settings -> About device -> Software update -> top-right button.

Rollback packages

The following packages will rollback your device to OxygenOS 12 (C.09), and will wipe all your data. Only the Indian rollback ZIP is available, as other regions haven't received the OOS13 beta yet.

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 choose either of the "Open Beta" update methods in the app's settings.
