Earlier we brought to you news about Oxygen OS 3.0 going through soak testing. However, here we are with the latest Oxygen OS 3.0 update straight from OnePlus 2 development team. The is a huge update that brings Android 6.0 Marshmallow to the manufacturer’s most popular OnePlus 2 device. This is a community build and right now it is under Beta testing. Hence, you may expect some bugs. However, this won’t be an issue because you can still receive further updates over the air. This Oxygen OS 3.0 Beta version is a daily-driver-material community release of for Oxygen OS. So if you don’t mind being a tester and some minor instability doesn’t bug you at all, then grab the Marshmallow ROM from the download section below. However, before you proceed, take a look at the features and bugs that come with it and make your decision. Moreover, this build is OTA eligible which means that you’ll receive all the future OTA updates including the stable release as well. Here’s what’s new in this build:

  • Android 6.0.1 Marshmallow upgrade
  • New OnePlus Camera UI
    • UI has been cleaned up: swiping up/down now switches between photo/video, whereas HD/HDR and flash settings live in the top right corner
    • You can now change the aspect ratio and toggle grid view without going all the way to the settings
  • New wallpaper picker
    • Easily preview and set both home screen and lock screen wallpaper in one place.
  • Shelf UX has been improved
    • No more edit mode, long press boards to rearrange or remove
  • General system performance improvements
    • Benchmarked 47% faster than OxygenOS 2.2.1 on key test scenarios
  • Fingerprint performance improvement
    • Tested 45% faster than OxygenOS 2.2.1 on average
  • Settings changes
    • Old app permissions are gone, say hi to new (native Android) app permissions.
    • Alert Slider has its own entry point with more customization options
    • Improved settings menu readability by changing the order a bit
  • March security patches
  • There are a few things you should be aware of:
    • Your fingerprints will not be preserved after you flash the new build, so you will need to re-register your fingerprints if you have fingerprint authentication set up
    • Maxxaudio tuner and presets will be removed
    • Rolling back to previous OxygenOS versions will not work without wiping data
    • Some soak testers have experienced wifi speed issues which we are investigating
    • Some of your old apps won’t work without an upgrade to M compatible versions
    • Shelf frequent apps board size might shrink if you are dirty flashing. Remove and re-add the board and it will fix itself
    • Language localization is still being improved

Before you proceed, backup everything just in case anything goes wrong. Read the instructions carefully before flashing. The OnePlus development team says “We only support dirty flashing of this build using Oxygen recovery. Dirty flashing requires OxygenOS 2.2.0 or higher. Factory reset is needed if you are using any other recovery or coming from any other ROM. We do not guarantee these cases to work properly.” Which means apply updates using Oxygen OS stock recovery without a factory reset. However, dirty flashing, meaning flashing the update without wiping data or factory resetting, requires OxygenOS 2.2.0 or higher.

Step 1. Before you proceed, make sure you have installed the base update prior to v 3.0. That means make sure you have Oxygen OS v2.2.0 or higher as you current firmware version.

Step 2. Now download the Oxygen OS 3.0 update zip file from the downloads and transfer it to your phone’s internal storage.

Step 6. When the installation completes, it will automatically reboot. If not, go back and reboot manually.
