How to Install Oxygen OS 2.1.1 on OnePlus 2

A new update comes to the OnePlus 2 for its ever so popular Oxygen OS taking the firmware to version 2.1.1. OnePlus recently released the Oxygen OS 2.1.0 update last month and here is yet another update to the ROM. It still isn’t Marshmallow though, but the update sure brings stability improvements and bug fixes. It is based on Android 5.1.1 Lollipop.

The Oxygen OS update v2.1.1 can be installed readily on the OnePlus 2 using the stock Recovery. However, to manually update to the latest version, you need to be on v2.1.0 and make sure you have not made any major changes to the system. If you have rooted your stock ROM, then you need to flash the full firmware via a custom recovery like TWRP. Make sure you have the latest TWRP recovery installed on your device. To install the OTA updates, you need stock recovery, custom recoveries like TWRP or CWM won’t work for this method.
