Until now, OnePlus One owners were able to install Android Marshmallow on their devices only via third-party ROMS. This phone, which was released exactly two years ago, with Android 4.4.2 KitKat out of the box, it was upgraded to 5.1.1 Lollipop and on top of the OS was running CyanogenMod 12.1.1 or Oxygen 2.1.4. Finally, Android 6.0.1 Marshmallow is ready to roll out, in the form of Cyanogen OS 13, over the air.

OnePlus has announced the news on its forums and owners of its first flagship should get Marshmallow in the next days, over the air. However, the official firmware for OnePlus One is Cyanogen OS 13 and it’s based on Android 6.0.1 Marshmallow.
