Google has announced and released the official new Developer Preview build of Android P for all Pixel 2 XL users.

If you wish to test all the new features and cool things added by Android P, then you can use the instructions below and learn how to manually flash the new files.

The new Android P Dev Preview factory image installation will wipe clean your smartphone, which is why you should create backups for all important files first. The Android P Final builds will be launched later this year, but until then you can see what Google has in plan by testing the preview builds.

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

  • use the tutorial for the Google Pixel 2 XL devices.
    - do not attempt to install any files you find in this post on any other different models.
  • you need to enable Developer Options if you haven't done it already: go to Settings> About Phone and tap seven times on the Firmware Build Number text.
  • now, open Developer Options, find USB Debugging and OEM Unlock options, then enable them both.
    - this will allow your computer and your Pixel 2 XL to connect via usb cable.
  • installing the Android P Developer Preview Factory Image will delete all the files from your smartphone's storage.
    - no file will survive the installation process, so you should create backups for all the important files before starting the install.
  • this guide has to be applied by advanced users only, we cannot be blamed in case you brick the phone nor in case you lose any important data files.
  • read the entire tutorial first and do not skip any steps.
  • check the battery charge levels and make sure that the Pixel 2 XL has 50% charge left before it powers off completely.
