Cyanogen OS 12.1 Update with Microsoft’s Virtual Assistant Cortana for OnePlus One (Installation Guide)

Cyanogen team has started to roll out new Cyanogen OS 12.1 update for OnePlus One that comes embedded with Microsoft’s virtual assistant Cortana. The new update (build YOG7DAS2K1) comes with December security patches and many bug fixes. This is an incremental update, so OnePlus One owners who are still on the Cyanogen OS (build YOG4PAS3JL) will receive the OTA update soon or can install the update manually.

In this guide, we show you how to manually update OnePlus One to the latest Cyanogen OS 12.1 update. One of the new features of this new update is the integration of Microsoft’s virtual assistant Cortana. However, if you prefer Google Now over Cortana, you can always uninstall this app, just like any other app.
