OnePlus 5T Android 8.1 Oreo-based OmniROM 8.1

OnePlus’s latest flagship smartphone of 2017 was the OnePlus 5 but the company later upgraded this smartphone with the launch of OnePlus 5T. The OnePlus 5T came with an edge to edge display along with a Full HD+ display and the smartphone also had the Dual camera setup as seen on the OnePlus 5 also. Apart from that, the smartphone came with Snapdragon 835 processor along with a combination of 6GB RAM and 64GB internal storage along with a higher variant of 8GB RAM and 128GB internal storage.

Now, we have also known that the OnePlus 5T was launched with the older version of Android which was Android 7.1.1 Nougat but the Android 8.0 Oreo update was already released. However, the company has rolled out the Open Beta 1 update for the OnePlus 5T which brings Android 8.0 Oreo to the device. Although, we should consider that the OnePlus 5T running on Open Beta 1 will be unstable to use as it is an early development build. Thus, you can now get the latest version of Android which installs Android 8.1 Oreo on your OnePlus 5T with the help of OmniROM 8.1. This build comes with the help of XDA Senior Member, darkobas, who is also the Device Maintainer for this ROM.

One thing to note with here is that the OmniROM 8.1 currently does not support no-verity file to be flashed currently which means that you will not be able to encrypt this particular build of the OnePlus 5T. Apart from that, it is also known that the OmniROM currently does not support SuperSU or Magisk flashing as well which means that you will not be able to get root access on your phone with this build

Now, if you are satisfied with not having encryption as well as not having root access then you can proceed with the installation of this ROM on your OnePlus 5T.
