ADB mode refers to AndroidDebugBridge mode, which is a mode of debugging and developing Android devices. In ADB mode, users can communicate with their mobile phones through ADB tools on their computers, and perform operations such as application installation, file transfer and debugging.

Activate ADB mode

To activate ADB mode, you need to turn on the developer option of the mobile phone first. The specific operation is as follows:

Open the "Settings" application of your phone.

Find the "About Mobile Phone" option and click Enter.

Click "Version Number" seven times in a row until the prompt "You have entered the developer mode" appears.

Go back to the "Settings" main interface and find "Developer Options".

Find the "USB Debugging" option in "Developer Options" and open it.

Connect the computer and start ADB mode.

After USB debugging, you need to connect the computer and start ADB mode, as follows:

Connect the mobile phone to the computer through USB cable.

Open the terminal or command prompt on the computer and enter the command "adbdevices" to see if you can recognize the mobile phone.

If the terminal or command prompt outputs the serial number of the device, it means that you have successfully connected to the mobile phone and started ADB mode.

It should be noted that there may be some problems when connecting the mobile phone, such as no driver installed and unstable USB cable connection. If you encounter these problems, you can try plugging and unplugging the USB cable again, or you can solve them by installing drivers.
