The Oxygen OS 3.0 Android 6.0 Marshmallow update is no life for the one plus 2 devices. Earlier we brought two tutorials about installing the latest Oxygen OS 3.0 for rooted and non-rooted OnePlus 2 users. However, if you have already installed the update on a nonrooted device and looking forward to installing a custom recovery and root it then this tutorial will help you for the same. When you update to Oxygen OS 3.0, your bootloader may get locked and you may lose root access as well. First, you need to verify that your bootloader is locked or unlocked. If it’s already unlocked then you can directly setup the modified TWRP recovery that supports the Marshmallow firmware on OnePlus 2. To root the device just flash the latest SuperSU package via TWRP.

Follow the tutorial below to unlock the bootloader, install a TWRP recovery and-and finally, root it. For this, you need to setup ADB and a fastboot environment. You can find all the necessary files in the download section below. This is a community build and right now it is under Beta testing. Hence, you may expect some bugs. This Oxygen OS 3.0 Beta version is a daily-driver-material community release of for Oxygen OS. Before you proceed, make sure you already are on official Oxygen OS 3.0 stock ROM. Also, take a nandroid backup once you setup the custom recovery

    When I fastboot oem unlock its just says okay in the terminal but doesn’t reboot my phone. I have all the latest drivers and adb and fastboot installed. Any idea on what I could be doing wrong?

    • Check if it is already unlocked. You can simply boot into fastboot mode and check the status. Also, you can issue the following command for that: fastboot oem devce-info
      This should give out unlock status as true or false.
