Steps to downgrade Android P to Android Oreo on Pixel device

  1. First, you should make sure that you have installed ADB and Fastboot on your PC. With these, you will be able to flash images via Fastboot commands. You can either simply download ADB and Fastboot.
  2. One will have to unlock the device’s bootloader to flash images in Fastboot. For them who have manually flashed the Android P can skip the step as the bootloader is already unlocked for them as a part of step 1. But if you have got the Android P as an OTA update by the upcoming beta program, you have to unlock the bootloader to flash the Android Oreo. But before unlocking, turn on the Developer Options menu on your pixel device and then open it and click on the switch on the right of “OEM unlocking“.
  3. Your Pixel device should be in bootloader mode before you can run any fastboot commands. For this, first power down your device and when the screen goes completely black, press and hold both the volume down and power buttons at the same time for about 10 seconds. You will now see Android’s bootloader menu as shown in the image:Downgrade-Android-P-to-Android-Oreo
  4. Now connect your phone to your PC and go to ADB and Fastboot installation directory. If you are using Windows, press the shift key and right click anywhere there’s blank space. Open the terminal and change the directories to the platform-tools folder in ADB installation directory with the ” cd <folder location>” command.Downgrade-Android-P-to-Android-Oreo-1
  5. If your bootloader is unlocked already, just skip this step. If you are ready to start, type the following commands from the ABD shell and click enter:
    fastboot devices

    If you see a number of letters followed by “fastboot”, then the device is properly connected.

    Execute the below command to unlock the bootloader on your device:

    Pixel or Pixel XL: fastboot oem unlock
    Pixel 2: fastboot flashing unlock
    Pixel 2 XL: fastboot flashing unlock_critical

    And click ‘yes‘ if you want to unlock bootloader and press the power button. Your bootloader will then unlock and the device will reboot to fastboot mode.Downgrade-Android-P-to-Android-Oreo-4
