Select Action: Choose your desired operation (e.g., Erase FRP or Factory Reset). Prepare the Device: Power off the phone completely.
The Connection Trick: Most modern MTK devices require you to hold Volume Up + Volume Down simultaneously while plugging in the USB cable. This forces the device into "Brom Mode."
