ADB Login

Overview

ADB (Android Debug Bridge) is one of the most convenient ways to connect to the A8550MA1, requiring no additional display or network configuration.

Prerequisites

Windows Environment

1. Download and extract the ADB tool package platform-tools
2. Add the extracted platform-tools directory path to the system PATH environment variable
3. Open CMD or PowerShell and run adb version to verify installation

Linux / macOS Environment

# Ubuntu / Debian
sudo apt update
sudo apt install adb

# macOS
brew install android-platform-tools

Hardware Connection

1. Connect the device using a USB Type-A to Type-C data cable
   • USB Type-A end to your computer
   • USB Type-C end to the A8550MA1's Type-C port
2. Power on the device and wait for the system to finish booting (STATUS LED solid green)

Establishing ADB Connection

# List connected devices
adb devices

# Example normal output:
# List of devices attached
# 47897135   device

If no device is listed:

• Verify the USB cable supports data transfer (not charge-only)
• Re-plug the USB cable
• Try a different USB port on your computer
