How to Downgrade OnePlus 5T to Nougat From Oreo Beta


Android 8.0 Oreo based OxygenOS Open Beta has already been released for OnePlus 5T and it is sure that some of you might have updated your phone to Oreo with this beta build. The Beta build is almost stable, but if you don’t like the update for some reason, you can revert back your OnePlus 5T to Android Nougat Open Beta build. Read on to know how to downgrade OnePlus 5T to Nougat from Oreo Beta.

OxygenOS Open Beta 1 brings several new features to OnePlus 5T, like Picture in Picture (PIP) mode, Auto-fill, Smart text selection, new Quick settings design, and more. However, if you are not happy with this update for any reason and want to go back to the previous Nougat build, then you can do that without much hassle.


Downgrading from a higher OS version to lower OS version is not always an easy method. A special downgrade version of the OxygenOS ROM is required. OnePlus has released a rollback build to downgrade OnePlus 5T to the lower version.

Note that, this process will erase all data from your phone, so backup any important data on the phone. Also, ensure that your phone has at least 50-60% charge remaining to prevent any unexpected shutdown during the installation process.
