OnePlus 2 was the first smartphone by the company to stop using the CyanogenMod custom ROM and instead run on the stock OxygenOS software. But the Cyanogen OS on OnePlus One helped the company gain the necessary momentum to stand out in the crowd. And now, it seems its successor will get the same OS with new builds of Cyanogen.

There are no official CyanogenMod ROMs available for OnePlus 2 smartphone for you to instal, but third-party CM ROMs have filled the void, despite some imperfections. Eagle-eyed Reddit users spotted the official CyanogenMod 12.1 and CyanogenMod 13 builds for the OnePlus 2 in the company's official GitHub repository, which suggests the latest flagship will finally be able to run the Cyanogen OS with official support.

The new builds, however, are not available for download and flash just yet, but are indeed on their way.

Once they are released, OnePlus 2 users will have the option to either flash their phones with Android 5.1.1 Lollipop (CM12.1) or Android 6.0 Marshmallow (CM13). The process will require rooting and installing the latest custom recovery, which renders the device's warranty useless.

The pre-installed OxygenOS on OnePlus 2 and OnePlus X is pretty great and offers extreme customisations like Cyanogen. Since the CyanogeMod fan base is vast compared to OxygenOS, some users might be keen to run the official CM builds.

The custom ROM maker hasn't officially announced the availability of CyanogenMod ROM for OnePlus 2, but the company recently released CM13 nightly builds based on Android 6.0 Marshmallow for select handsets.

On the other hand, OnePlus also revealed the Android 6.0 Marshmallow rollout schedule for its devices to take place in 2016.
