ADB Connection Method (Android Debug Bridge)

Overview

ADB (Android Debug Bridge) is a software-based connection method that allows communication with an Android device while the operating system is running or partially running.
It is widely used for debugging, device management, and controlled servicing operations through a secure command interface.

ADB operates at the Android system level and requires explicit authorization from the device.

When Is ADB Required?

ADB is typically used when:

• The device boots into Android or Recovery

• USB Debugging is enabled

• The device is unlocked or authorization is granted

• FRP or software servicing is supported via ADB by the tool

• System-level commands or data access are required

• Fastboot or Download Mode is not necessary

How Does ADB Work?

ADB establishes a client–server connection between the computer and the Android system.
Once authorized, the repair tool can communicate with Android services to perform supported operations such as diagnostics, configuration, and limited security servicing.

ADB does not provide direct hardware or bootloader-level access.

How to Connect (ADB)

Method 1: Normal Android Mode

1. Power on the device normally

2. Enable Developer Options

3. Enable USB Debugging

4. Connect the device to the computer via USB

5. Approve the ADB authorization prompt on the device

6. The tool detects the device via ADB

Method 2: Recovery Mode (ADB Sideload / Limited ADB)

1. Power off the device

2. Boot into Recovery Mode

3. Select ADB / Apply update from ADB (if supported)

4. Connect the device to the computer via USB

5. The tool establishes a limited ADB connection

📌 ADB availability and permissions depend on device model and security patch level.

Important Notes

• USB Debugging must be enabled

• Authorization is required on the device

• Access level is limited by Android security

• Not available on powered-off devices

• FRP-related functionality depends on tool support

Summary

ADB is a flexible and widely supported connection method for Android devices that are operational and authorized.
It is suitable for system-level servicing and diagnostics but is limited compared to bootloader or chipset-level modes.
