Right-click your Desktop name in Device Manager -> Add legacy hardware Ports (COM & LPT) and browse to your driver files. 2. Disable Driver Signature Enforcement
In every case, the root cause is the same:
The error message (often appearing in tools like Maui META or Modem META) typically indicates a communication breakdown between your MediaTek (MTK) device and your computer during the "handshake" phase. This handshake is a critical negotiation where the software attempts to verify the device's identity and state before allowing operations like IMEI repair or NVRAM editing.

I’ve been trying to get this device to work properly for modem handshake communication, but unfortunately, the system consistently fails to detect the . Without that port, I can’t establish a reliable handshake with the modem, which is a critical part of my workflow.
The most common cause is missing or improperly installed drivers. MTK VCOM Drivers
Without a successful handshake, you cannot flash firmware, repair IMEI, debug baseband issues, or perform advanced diagnostics. This article will explain what this error means, why it happens, and how to resolve it permanently. The handshake often fails because the timing or
Windows 10 and 11 often block unsigned or third-party drivers by default, preventing the META port from initializing.
