Prerequisites

  • 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 the Power key to enter Fastboot mode. After that, connect your Zenfone 8 to your PC via a USB cable.

Step 2

Decompress the Android 13 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 there is a stable connection between your Zenfone 8 and PC during the flashing process.

Step 3

When the flash update finishes, a ‘Download Complete’ message will appear on the terminal. Hit the Enter key on the keyboard to restart your Zenfone 8. If any failed message appears on the terminal, the flash was unsuccessful. In this case, please try again or report the issue.
