OxygenOS 12 comes to the stable track for Nord CE

Full ZIP links are available in the app so you can update ASAP

Global & EU received OOS12 on 19th August 2022 (C.05), and we've added links to rollback ZIPs for both regions at the end of this article.

OnePlus Community post is finally up, added its link. We've also edited the article to include a newer rollback ZIP at the end, provided by OnePlus. The old one would roll your device back to, while the new one gets you to (last OxygenOS 11 version).

Only the Indian variant of the Nord CE received an OxygenOS 12 Open Beta (C.03), which seems to be a common theme post Oppo-merger. That device then received a stable OxygenOS update to C.04 on 25th July 2022, hinting at a global & EU release coming soon. There isn't any forum post up yet. It went live on 2nd August 2022 along with a newer rollback ZIP (takes you back to which was the last OOS11 version).

With every new device receiving OOS12, we always advise our users to be patient and not jump into it without thinking. Every "first build" — even stable — is usually quite buggy and is almost always met with general disappointment. For example, 9-series got the first stable build on 6th December 2021, which was pulled shortly after rollout. Every device has received a few bugfix releases, but users are still complaining about genuine bugs. For example, my 8T is on the latest release for it (C.21), but none of these issues are still fixed (other devices also have some of these bugs):

  • Android Auto shows a "searching for GPS" warning; makes it very difficult to navigate unfamiliar roads (e.g. on a trip)
  • Double tapping on the lockscreen doesn't always turn screen off
  • USB choice dialog pops up every single time, even though I've already set a default
  • Going to the home/recents screen from an app that supports Material You's dynamic colour lags like crazy, regardless of using gestures or buttons

Anyway, if you wish to update to C.04, you can do so via the app itself, since it has full ZIPs available for India.

Back when the 9-series got their first OOS12 build, OnePlus had posted a short FAQ to prepare users. You can go through it if you haven't already: https://community.oneplus.com/thread?id=1519491. There's a "peek inside OOS12" thread as well: https://community.oneplus.com/thread?id=1529132.

Where can I install stable OxygenOS 12?

If you're currently on the stable track, you should have already received a notification from the app about the C.04 update. If you have an Indian device, please ensure you've selected either of the stable update methods in the app's settings, since the beta track doesn't receive updates separately from stable anymore (post Oppo-merger). Beta track is now meant only for the first few major Android builds, nothing more. Disable advanced mode as well, in case it's turned on for whatever reason. The stable track will continue to receive updates until the device is marked EOL (End-of-Life).

Once you're on the main screen of the app, simply download the update presented to you and follow the installation guide. Note that C.04 has rolled out only to Indian devices so far, not global/EU yet. Email us at [email protected] or join our Discord server if you receive C.04 on your global/EU device.

Can I revert to OxygenOS 11?

Rolling back will completely wipe all your data, so please take a backup before proceeding. For detailed instructions, go through the C.04 community post.

Below is the rollback/downgrade packages for the OnePlus Nord CE. 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 upgrade" will once again be visible in Settings -> About device -> Up to date -> top-right button.

Rollback packages

The following packages will rollback your device to OxygenOS, and will wipe all your data. Ensure you choose the correct region.

Remember: these are rollback packages — they're not the packages you should download if you're looking to update to the latest stable version. For that, close this news article and ensure you've selected either of the "Stable" update methods in the app's settings.
