Steps to update Nexus 5X, Nexus 6P to NRD91N, NBD91K Android 7

Required files: Download factory images for your Google device from here. Remember to download the factory images, NOT the OTA files.

  1. Connect your device using a USB cable and turn it off. Make sure that Fastboot is installed on your PC.
  2. Now, start the device in Fastboot mode: Turn on the phone while pressing and holding the Volume Up + Volume Down + Power keys until you see the Fastboot menu and the START text on top.
  3. Extract the downloaded Android 7.0 file on your PC. Go to _NRD91N_ (depends on your device) folder and copy/paste all the files to your Fastboot directory (which often is the platform-tools folder inside the Android SDK directory).
  4. This step involves flashing the desired factory image to your Nexus device. Open the folder containing the Android Nougat factory image downloaded and extracted. In the address bar, type cmd and type the command written below and press enter.
    1. On Windows: Run flash-all.bat
    2. On Mac: Run flash-all.sh using Terminal
    3. Linux: Run flash-all.sh
  5. Once the script finishes running, your Nexus device will reboot. First boot may take up to 5 minutes, so don't worry if it takes your device longer than usual to boot up.
