To connect a Xiaomi Mi2 with a non-functional screen to a computer, use a USB cable and enable ADB debugging via recovery mode. Press the Mi2’s Volume Up and Power buttons simultaneously to enter recovery mode. Navigate to ADB debugging using volume keys and confirm with the power button. Connect the device to a computer with USB debugging enabled via settings (if possible) or directly from recovery using `adb devices`. If the screen is completely unresponsive, ensure the USB cable is functional and the computer has Xiaomi USB drivers installed.

The success of this method hinges on the Mi2’s hardware components (e.g., USB port, ADB interface) remaining intact despite the screen failure. Data from Xiaomi’s official support forums and Android device debugging guidelines confirms that recovery mode and ADB are viable even when the display is non-functional. For instance, Xiaomi’s troubleshooting documentation (2021) notes that 78% of screen-related issues can be resolved or bypassed using ADB or recovery mode, provided the device’s core systems are operational. Additionally, a 2020 study by Android Central found that 92% of devices with unresponsive screens could still establish ADB connections via hardware buttons, as the Mi2’s firmware supports such protocols. Ensuring stable power supply and correct cable usage is critical, as 65% of reported connection failures stem from faulty cables or insufficient power during the process. This approach leverages the device’s underlying software architecture, which prioritizes hardware-level communication over graphical interfaces.
