The official Android 8.1.0 factory images are now live for the Google Pixel smartphones. Check the info in this post and learn how to manually flash the new firmware factory image on your device.

The new official update should reach the Pixel phones over-the-air worldwide in the following days, but in case you are running a custom ROM, and you wish to restore the phone to stock Android, or you simply wish to refresh the installed OS, then you can install the factory image instead.

Android 8.1.0 Oreo brings tons of new features and improvements over the previous 8.0 Oreo firmware.

Before starting the installation process you need to check the following guidelines:

  • use this tutorial only with the Google Pixel phones.
    – don’t use the tutorial for other different devices.
  • enable USB Debugging and OEM Unlock from the Developer Options menu.
    – the Developer Options might be hidden which is why you will have to enable them first: go to Settings> About Phone> and here you need to tap seven times on the Build Number text.
    – get back to Settings, open the Developer Options and enable USB Debugging and OEM Unlock.
  • backup all the important data files before starting the installation process.
    – the bootloader will be unlocked during installation and that will trigger a ‘complete data wipe’ process and no files will survive the process.
