Download and Flash OxygenOS On OnePlus 3 (Stock ROM)

Flashing OxygenOS stock rom / firmware on OnePlus 3 is very easy: just like installing a downloaded APK file on your Android device :P. The ROM to download from the link below is OxygenOS 3.1.2 and is meant only for OnePlus 3. Flashing on any other OnePlus device will cause a brick.

Download the ROM from link below and follow the flashing instructions in this post to learn how to flash. If you are using a custom recovery like TWRP, you can also flash OxygenOS without issues. But I strongly recommend that you flash over Oxygen Recovery. Download Oxygen Recovery for OnePlus 3 here.
