Frequently Asked Questions

MediaTek CDC Serial Driver FAQs

Common questions and troubleshooting answers for installation and connectivity issues.

What is the MediaTek CDC Serial Driver?

It is the USB communication driver that creates a virtual COM port for MediaTek devices in META mode, required by Maui META, SN Write Tool, and SP Flash Tool.

How does CDC Serial differ from VCOM?

VCOM handles the initial Preloader handshaking for flashing firmware, while CDC Serial handles modem diagnostics, AT commands, and NVRAM calibration.

Why does SP Flash Tool fail with BROM Error 0x7D4?

BROM 0x7D4 or handshake drops occur when the CDC or DA USB driver is missing. Installing this CDC driver fixes the COM disconnect.
