The official Android 8.1.0 February 2018 OTA updates are now live for all the Google Pixel devices.
In case you don't wish to wait until Google sends the updates in your region, then you can manually install the Android 8.1.0 OTA Update images using ADB Sideload method.
These updates are normally rolled out in stages, and not everyone will get the files at the same time. There aren't too many changes added in this release, but you should still install one every time it gets released, as it packs the latest security patches. Before starting the flashing process you need to check the guidelines below.
Use this guide only for the Google Pixel devices. Don't try to flash the new update on any other different Pixel devices.
This update has to be installed over the previous Android 8.1.0 builds. Don't try to install it over older Android 7.1.2 builds, as it won't work.
You need to enable the USB Debugging and OEM Unlock from Developer Options menu. If you cannot find Developer Options, then you should enable it first: go to Settings> About Phone and tap seven times on the Firmware Build Number text.
Return to Settings, as the Developer Options will now be listed and you can open it. Enable USB Debugging and OEM Unlock.
This guide has to be used by advanced users. Don't blame us in case you brick the phone nor in case you lose any data files.
