Update OnePlus 2 to OxygenOS 3.0.2 Official Android 6.0.1 Marshmallow Firmware

OnePlus's Staff  Member Helen at the forum just announced and released OxygenOS 3.0.2 which brings the Final Build of Android 6.0.1 Marshmallow to the OnePlus 2. After months of delays and false promises, OnePlus seems to have finally released the much waited OOS 3.0.2 based on Marshmallow Firmware that users had been waiting for a very long time.

Since Oxygen Team was not able to roll out Marshmallow update in Q1 of this year to meet deadlines by Carl Pie (OnePlus CEO), they have previously released the Community Build 1 and Community Build 2 so eager users can try out the new update before it was released publicly for everyone.

An OTA (over-the-air) update will be an incremental rollout which should reach 100% coverage in the next 48 hours or so.

But for those who do not want to wait can grab the OTA update file directly from this tutorial.

You will be able to update OnePlus 2 to OxygenOS 3.0.2 based on Android 6.0.1 Marshmallow using this complete tutorial. We covered installation process for all Rooted, Non-Rooted, Stock Recovery, TWRP Recovery users.

This tutorial doesn't matter whether you are in Previous version of Oxygen OS or Any other Custom ROM. We will cover all the steps for you.

This update is packed with new features and enhancements. One thing to note is that this update will clear your stored fingerprints on Dirty Flashing method. If you have fingerprint authentication set up, you will need to re-enroll again before use.

Here are some of the highlights of this update:
  • Android 6.0.1 Marshmallow upgrade
  • Enhanced Doze mode for better battery life
  • System wide performance improvements
  • Improved fingerprint sensor performance and recognition
  • New OnePlus Camera UI and AF optimization
  • MaxxAudio and Tuner have been removed. We have integrated with Dirac HD Sound technology for the speaker so you get a great experience without the knobs and dials
  • Shelf UX has been improved. You can now long press to edit a board
  • You can now lock apps in recents so they won't be cleared away. We've also added clear process in addition to clear-all for those of you who want a better control of background processes
  • Network operator selection will now stick to your choice so you don't accidentally roam onto unintended networks
  • Swiftkey update to 6.3.3
So let us know what you think. Enjoy the tutorial below!
