The "handshake" is a multi-stage authentication process where the PC software (the host) and the phone (the target) exchange identity packets to confirm they are ready for high-speed data transfer. If the specific or Meta USB COM port drivers are missing or mismatched, the tool will timeout and trigger this error. Primary Causes of Connection Failure
Select .
This is the single most common cause of the error. The standard Windows drivers are not sufficient to access the META mode. You need dedicated MediaTek drivers.
A clean driver installation is essential to ensure there are no remnants of old, conflicting drivers. it cannot find the meta usb com port for modem handshake
The error is a common and frustrating issue encountered when flashing firmware, repairing IMEI numbers, or unlocking MediaTek (MTK) smartphones.
