How to Install OTA Update on a Rooted Nexus 6

Your Nexus 6 will not install OTA (over-the-air) update if the phone is rooted or the bootloader is unlocked. Even if you have uninstalled the root and custom recovery from your phone, the OTA updates will not install on it. This is because of changes to the system image made by root and custom recovery. There is a workaround to resolve it.

Checkout the below guide to know how to install OTA update on a rooted Nexus 6. Thanks to the XDA user bitpushr, he has discovered a method to install OTA (over-the-air) updates, even if your Nexus 6 is rooted. You only need factory image and corresponding OTA system image in hand.
