Finally, OnePlus has released OxygenOS 2.1.4 for OnePlus One, which offers new features, clean and unburdened user experience. This version of OxygenOS is a full firmware package, so it is not available via OTA (over-the-air). You will require flashing the firmware manually. The below guide explain how to update OnePlus One to the latest OxygenOS version 2.1.4 manually.

Due to hardware limitations, not all features of OnePlus 2 are included in the OxygenOS version 2.1.4 for OnePlus One, such as manual camera mode, MaxxAudio and screen temperature slider. However, owners of OnePlus One can enjoy all other unique features of OxygenOS like Dark Mode, custom icon packs, App permissions, double tap to wake and all other gestures.



Before you start installing the OxygenOS 2.1.4, please note that DO NOT flash this build through TWRP custom recovery. You will most likely lose your radio and IMEI number, which means, you will not be able to use your phone with any network.
