It Cannot Find The Meta Usb Com Port For Modem Handshake -

Windows 10 and 11 often block MTK drivers because they lack digital signatures. Update & Security Advanced startup Restart now Navigate to Troubleshoot Advanced options Startup Settings to "Disable driver signature enforcement". Reinstall the drivers while this mode is active. 3. Proper Handshake Sequence

Low-quality USB cables or front-panel PC ports may not supply sufficient current to keep the modem in meta mode. A handshake requires stable voltage; fluctuations cause the port to disappear. it cannot find the meta usb com port for modem handshake

When the device enters "Meta Mode" (bootloader mode), it often changes its USB Product ID (PID) and Vendor ID (VID). If the operating system does not have a driver pre-installed that recognizes this specific PID/VID combination in bootloader mode, it will either ignore it or assign a generic, non-functional driver. The flashing tool looks for a specific "USB Serial" driver to create the COM port; if that driver is missing, the COM port is never created. Windows 10 and 11 often block MTK drivers

Not all USB cables are created equal. Many charging cables lack the data wires necessary for data transfer. Even if the cable works for other things, high-speed handshake protocols can fail due to signal degradation caused by a cheap cable or a loose port.
