It Cannot Find The Meta Usb Com Port For Modem Handshake Jun 2026
Some software (e.g., WriteIMEI, Maui META) expects the COM port number to be manually entered. If you leave it on "Auto" but the port number changed, the error appears.
At the physical layer, the issue is often deceptive. Standard USB cables are designed to deliver power and handle high-speed data transfers for media, but they may lack the shielding or wire quality required for the low-level, high-sensitivity signaling used during a bootloader handshake. A cable that successfully transfers photos or charges the battery might still fail to sustain the precise voltage drops and pull-up resistor signals required to trigger the Preloader mode. Furthermore, hardware USB hubs, front-panel ports, and USB 3.0 controllers frequently introduce latency or signal degradation that disrupts the handshake. The MediaTek Boot ROM expects a near-instantaneous response; a delay of a microsecond caused by a hub's controller can cause the device to ignore the computer and proceed to boot normally into the OS.
Provide your phone model, chipset (e.g., MT6765), and the name of your flashing tool in technical forums like XDA Developers or GSM-Forum. Include a screenshot of your Device Manager with Ports expanded. Happy flashing! it cannot find the meta usb com port for modem handshake
The device is booting straight to charging or normal mode instead of holding the Preloader state.

Press and hold the correct boot keys. For most MTK devices, this is or Volume Up + Volume Down simultaneously. While holding the keys, insert the USB cable into the PC. Standard USB cables are designed to deliver power
MediaTek devices require different physical button triggers to force the hardware bootloader to negotiate a handshake instead of just pulling charging current. Try these variations when plugging in the USB cable:
Because MediaTek CDC and VCOM drivers are often unsigned legacy tools, Windows 10 and Windows 11 will automatically block them from installing properly.
On Windows 10/11, you disable Driver Signature Enforcement first: Go to Settings > Update & Security > Recovery . Under Advanced Startup , click Restart Now .
