    Installing the MediaTek Preloader USB VCOM driver is a critical step for using tools like SP Flash Tool to flash firmware on MediaTek-powered Android devices. On modern Windows versions (10 and 11), this usually requires a two-part process: disabling driver signature enforcement and then manually adding the hardware. Step 1: Disable Driver Signature Enforcement

    Windows 10 and 11 prevent the installation of drivers that are not digitally signed by Microsoft. Since many MTK VCOM drivers are unsigned, you must temporarily disable this security feature.

    Open Settings > Update & Security (Windows 10) or System (Windows 11). Right-click the device → Update driver → Browse

    Select the Recovery tab and click Restart now under Advanced startup.

    After the PC restarts into the blue menu, navigate to Troubleshoot > Advanced Options > Startup Settings > Restart.

    Once the Startup Settings list appears, press 7 or F7 on your keyboard to select Disable driver signature enforcement. Step 2: Install the Driver Manually

    Once your PC reboots with signature enforcement disabled, you can manually install the driver through the Device Manager. How to install Mediatek USB VCOM drivers in Windows | Issue | Solution | |--------|----------| | Device
