Navigate to . Press F7 to disable driver signature enforcement.
Look for a device appearing under "Ports (COM & LPT)" or "Other Devices" with a yellow exclamation mark (often named MT65xx Preloader ).
Proper preparation significantly improves your chances of success.
If your device has a removable battery, take it out, insert the cable, and quickly insert the battery if the software prompts you. Verifying the Fix
If all the above fails, the phone’s modem firmware itself may be corrupt. The handshake fails because the modem does not respond. In this rare case: it cannot find the meta usb com port for modem handshake
Sometimes the handshake fails because of poor physical connectivity.
Most handshake failures happen because the PC doesn't recognize the device in its "Meta" state. Install VCOM Drivers:
Manually install the driver through by selecting Action > Add legacy hardware and browsing to your downloaded .inf files. Step 2: Force Manual COM Port Assignment If the driver is installed but the port doesn't appear:
In this detailed guide, we will explore: Navigate to
When a powered-off MTK device is connected to a computer, it briefly boots into a temporary state controlled by the MediaTek Preloader .
For modern MTK devices (Helio G-series, Dimensity), use CM2 (Infinity) , which handles COM port detection more robustly via USB Debug + Diag mode together.
MediaTek devices have a very short window (1-2 seconds) during boot where they are in PreLoader mode, ready to accept a handshake. If the software isn’t already waiting or if you plug the phone in too late, the device exits Meta Mode and boots normally, causing the COM port to disappear.
Fix: "It Cannot Find the META USB COM Port for Modem Handshake" Error The handshake fails because the modem does not respond
If you have overlapping or broken driver installations, the handshake will fail.
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.
No. Virtual emulators (like com0com) cannot replace the physical USB-to-serial bridge inside the phone’s CPU.
Download and install a verified MediaTek USB Driver package (such as MTK_USB_All_in_One_Driver or LibUSB-Win32 filters). Use Device Manager to Force Install: Open Device Manager on your PC.
Download a trusted driver package, such as the or MTK USB VCOM Drivers v1.0.8 . Open Windows Device Manager .
Newer USB 3.0/3.1 ports are often too fast for older modem protocols. If you only have blue ports, try using an older USB 2.0 cable. ⚡ 3. The Power Cycle Trick
