How to opt-in to Android 12 Beta

Prerequisites

Before installing the Android 12 Beta:

  • Please back up any personal data first. All user data will be erased after installing the firmware.
  • Ensure your battery's charge level is higher than 20%.
  • Make sure that no screen lock (pattern, PIN, or password) is set on your phone.

Step 1

Turn the device off, hold down the Volume Up key and then hold down Power key to enter Fastboot mode. After that, connect your Zenfone 8 to your PC via a USB cable.

Step 2

Decompress the Android 12 image file, and then use the included scripts to flash your phone:

  • Windows: Double click on the update_image.bat file
  • Ubuntu: Execute update_image.sh
  • MacOS: Execute update_image_for_mac.sh

Caution: Do not unplug the USB cable and ensure a stable connection between your Zenfone 8 and PC during the flashing process.

Step 3
