Face-X series upgrade firmware

Preface

Before reading this chapter, please read the upgrade firmware chapter above.

The way Face-X series upgrades firmware is basically the same as that in the upgrade firmware chapter. However, Face-X series is equipped with a shell, and the recovery button is not exposed, so here we use another way to enter the upgrade mode:

1. After Face-X series is powered on, click the gear pattern on the upper right corner, and enter the password 123456 to enter the setting.
2. Open USB OTG options.
3. Connect OTG port of the Face-X series and computer with dual male USB date cable.
4. After the ADB is installed, enter the adb reboot loader in CMD, and the machine will enter the upgrade mode. Follow the upgrade firmware chapter to complete the remaining steps.
