How to root OnePlus One on Cyanogen OS 12S Lollipop ROM Cyanogen

Cyanogen Inc recently rolled out the highly-anticipated Android 5.0.2 Cyanogen OS 12S ROM for the OnePlus One, while folks at XDA Developers have already released the built-in rooting tool for the flagship phone running on the CM12S ROM.

The first root for CM12S Lollipop ROM is now available on OnePlus One, with due credit to XDA Developers senior member, inscythe. The developer explains that he has uploaded the flashable zip containing the debuggable boot.img from official CM servers and added the su binary to it from the latest CM12 Nightly release.

The CM version of SuperSU (flashable zip) has reportedly been tested by the developer and found to be working fine. It is further ascertained that the CM12S root will unlock super user access in both apps and ADB.

Interested users can go ahead and install the CM version of SuperSU on the OnePlus One, using the step-by-step guide provided below.
