Other Ways to Install OTA Updates

Get back to Stock Recovery and wait for Official OTA

Most easiest way is to install stock recovery on your rooted device and wait for update, Its safest and simple. As we are discussing here for Rooted device and I am assuming your have eaither TWRP/CWM installed. If you are able to get the stock recovery for your device then watch the below video to remove the custom recovery.

Install using ADB Sideload Method

For this demo I am using Google Nexus 6P which is running Android Nougat 7.1.1. We will be seeing how to update and install latest security patch level.In case you are installing on Nexus device download the latest factory images from below.


Once you have the Flashfire installed, copy the factory image on your android device. and open the app and select the Plus icon. You will get oiptions as shown below,


Now click on the "Flash Firmware Package" and browse the factory image. Once you open the file it will take few time to read the complete package.


The important point is if you are just installing the OTA and wanted to leave all your data as it is uncheck the "Data". If you also wanted to just leave the current recovery which is installed then uncheck the "Recovery" also,

On the top right end there is a tick button. CLick it and see the review windows as below,


Now click the "Flash" button. It will optionbally give you a final warning message.


Press on OK and leave you phone until it finishes the installation and update. It may take a few minutes.
