Reason: ADB cannot detect your Android device due to USB debugging not enabled, incorrect drivers, or a faulty cable.
Solution: Ensure USB debugging is enabled on your device, install the correct USB drivers, and try a different USB cable.

2. Using Wrong ADB Commands

Reason: Typographical errors or using outdated/incorrect commands can lead to data loss or failure to backup/restore.
Solution: Double-check your commands against reliable sources and ensure accurate typing.

3. Insufficient Storage Space

Reason: Lack of storage space on either your computer or Android device can interrupt the backup or restore process.
Solution: Free up storage space on both your computer and your Android device before attempting the operation.

FAQs

What is ADB and how do I install it?
ADB (Android Debug Bridge) is a command-line tool included in the Android SDK Platform-Tools. Download the platform-tools zip file from the official Android developer website, extract it, and add the directory containing `adb.exe` (Windows) or `adb` (macOS/Linux) to your system's PATH environment variable. This allows you to run ADB commands from your terminal or command prompt.
What if I get an error during backup or restore?
Errors can occur due to various reasons like insufficient permissions, incorrect device connection, or corrupted data. Ensure your device is properly connected and authorized for USB debugging. Check the ADB log for detailed error messages. Sometimes restarting your device or computer can resolve temporary glitches. If the problem persists, double-check your commands for typos and ensure the correct app package name is used.
