Recently OnePlus One received Android Marshmallow update that is Cyanogen OS 13. First, the update was available via OTA and an incremental update zip file. Now the full flashable zip file for Cyanogen OS 13 ZNH0EAS2 is available on Cyanogen. So now you will be able to install fresh Cyanogen OS 13 instead of just upgrading.

I have been using CyanogenMod 13 on my OnePlus One for quite a long time but, even after several updates it was stable and shouldn’t be used as a daily driver ROM. But now when official Android M update is released you can update your phone to Android M without any worry of an unstable or buggy ROM.

In this tutorial, we are going to look at how to install Cyanogen OS 13 manually via the recovery. So make sure you backup all your important data like contacts, SMS, call logs etc. You don’t need to worry about the data in your internal memory as in this process your data partition will be untouched.
