Clean Installation Guide for OxygenOS 3.0 on OnePlus 2 [Beta Build]

Some of you know, soak testing for OxygenOS 3.0 (based on M) started a few weeks ago, and now OnePlus ready to share it with us. OnePlus still want to ask the community for help to make sure OnePlus work out any remaining kinks before OnePlus OTA the build officially.
What’s available today is a daily-driver-material community release of 3.0. If you’re the type who won't mind rolling up your sleeves a bit to get your Marshmallow on, this one’s for you. OnePlus would like to ask for a little help with testing some aspects of the software that require a larger user base around the world. Here’s what OnePlus need your feedback on :
  • Network testing (how is this update working on your specific carrier, your specific region?)
  • Are you noticing improvements to the camera (both UI and picture quality) ?
  • Performance and battery life - let us know how your phone runs.
This build is OTA eligible which means you’ll receive future OTAs on this build so don’t worry about not getting updates if you flash this.

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 we want you to 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

Most of the TWRP Users must be knowing it that by wiping /data they will be lossing all installed Apps. So, I recommend using Titanium Backup Pro to Backup all user apps and restore them after the clean flash. This way, your all apps will remain intact. Clean flash, undoubtedly, is the best way to flash.
