Your Guide to the IR-Controlled Recovery Tool

Table of Contents

1. Introduction

Welcome to the EsMicro! This tool is a powerful, compact utility designed for technicians working with Android TV motherboards. Its primary function is to provide a direct UART (serial) interface to diagnose issues and send recovery commands. The tool is operated exclusively using a standard TV remote control.

2. Getting Started

Hardware Overview

Powering On

The EsMicro does not have an internal battery. To use it, connect a Micro USB cable from the tool to any standard USB power source (like a computer, power bank, or USB wall adapter). The splash screen will appear, followed by the Home Screen.

3. IR Remote Control (Required)

Important: You cannot operate the EsMicro without a compatible TV remote. The tool has no physical buttons for navigation.

The EsMicro is designed to be controlled by many common TV remotes. Point your remote at the IR receiver on the tool to navigate its interface.

5. The UART Toolkit (In-Depth)

After selecting "UART Mode" from the main menu, you'll proceed through these steps.

First, select the correct communication speed (baud rate) to match the device you are connecting to. Use ◀ / ▶ to cycle through speeds (e.g., 9600, 115200) and press OK to confirm.

5.2 The UART Terminal

This screen displays all incoming data from the connected device. From here, you can access several command menus using your remote:

5.3 Sending Chip Commands

This menu contains pre-programmed commands for popular TV chipsets.

  1. From the terminal, press SOURCE to enter Chip Select.
  2. Use ◀ / ▶ to choose a chipset (e.g., MStar, Amlogic) and press OK.
  3. Select a command (e.g., "Recovery 1", "Wipe Cache") with ◀ / ▶.
  4. Press OK to send the command to the TV.
  5. All Recovery: This special option automatically sends a sequence of common factory reset commands to the target device.

6. Updating Firmware via Wi-Fi

The EsMicro can update itself over the internet. You will need a TV remote with number keys for this process.
