Understanding why the software drops the connection requires looking at how a MediaTek device boots. When you plug a powered-down MTK device into a PC, it briefly initializes a temporary preloader state. The flashing software must catch this precise window to send a command packet (the "handshake"), forcing the device to switch into META mode.
Failure at step 3 or 4 results in the error: "Cannot find the meta usb com port."
Different devices require different keys to trigger META mode. Try these variations when plugging in the USB cable to a powered-off device: No buttons held down (standard). Hold Volume Down only. Hold Volume Up only. Hold both Volume keys simultaneously. Step 5: Configure the Software Settings
