OnePlus One has rocked the smartphone market ever since it was released in 2014. The phone by-default runs on Cyanogen OS – the most entrusted aftermarket firmware. We are well aware of all its features, and most of all, its update assurances. The phone has proved well, its efficiency and performance to all the other smartphones in its range.
One thing that OnePlus and Cyanogen take pretty seriously, is the user feedback. They work on them and provide their users with fixes through regular updates. The software distributor has now published the latest Cyanogen OS 12.1 OTA for the OnePlus One, which is based on Android Lollipop 5.1.1. The update is already available to the users as Over-The-Air update. But, if you’re a bit skeptic about automatic update installation or may be just some who likes the manual way, then you can use our instructions to manually install the incremental update or the full update. This guide will help you update to Lollipop 5.1.1 by flashing Cyanogen OS 12.1 OTA on OnePlus One.
The update will upgrade your OPO to Cyanogen OS 12.1 (build: YOG7DAS2K1). The update fixes a majority of security vulnerabilities related to stagefright on Android.
Please note that this incremental update should only be installed on the OnePlus One running Cyanogen OS 12 (Build: YOG4PAS3JL). However, the full update zip could be flashed on your OnePlus One running any of the previous builds.
