OnePlus Nord 2T launched on 20th May 2022, and came with OxygenOS 12 out-of-the-box. It was the seventh device to get OxygenOS 13 Open Beta (10 Pro was the first, 9 & Pro were second, 10R was third, 9RT was fourth, 10T was fifth, Nord CE 2 Lite was sixth), although it was "Open" only in name. 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 Nord 2T and the Nord CE 2 Lite, 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, the first OOS13 stable build is out only for India so far, and carries the C.23 version number. Complete timeline for Nord 2T OxygenOS 13 builds:
- 1st December: Beta program starts
- 13th January: first stable build (C.23 for India)
With every new device receiving a major Android update, 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 OOS12 build on 6th December 2021, which was pulled shortly after rollout. All OOS12 devices have received many bugfix releases, but users are still complaining about bugs; few of them are major ones. What's even more annoying is that the bugs I experienced on OOS12 still exist on OOS13 (OnePlus 8T). None of these issues have been fixed since OOS12's first release (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)
- Gmail notifications don't always get through, despite there being more than enough free space on the device
I've even done a factory reset, to no avail. There's no battery optimization option in Gmail's "app info" screen; all other apps have it.
- 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
This is extremely annoying, wasn't like this prior to OOS12
- Going to the home/recents screen from an app that supports Material You's dynamic colour lags a lot, regardless of using gestures or buttons
If you wish to update to OOS13, you can do so via the app itself, since full ZIPs are available. Rollback instructions are at the end of this article.
OnePlus recently posted an OOS13 FAQ (Frequently Asked Questions) to prepare users, you can go through it if you haven't already: https://community.oneplus.com/thread?id=1131425685828009991. There's an AMA (Ask Me Anything) as well: https://community.oneplus.com/thread?id=1156848409773604866.

Where can I install stable OxygenOS 13?
If you're currently on the stable track, you should have already received a notification from the app about this update. 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.
Can I rollback to OxygenOS 12?
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 & 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). Also ensure it ends with ".zip".
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 -> Up to date -> top-right button. Alternatively, try this APK instead (provided by OnePlus): https://oxygenos.oneplus.net/OnePlus_tools.apk. Find it in your app drawer after installing, it should be labelled “System update”.
The following packages will rollback your device to OxygenOS 12 (A.17), and will wipe all your data. Only Indian rollback ZIPs are available, because other regions haven't yet received OOS13; we'll update this article when OnePlus posts them.

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.
