Beyond booting the OS, the preloader serves a crucial secondary purpose: . When a device is connected to a computer via USB while powered off, the preloader creates a temporary virtual COM port (MediaTek Preloader USB VCOM Port). This port allows specialized desktop flashing tools to communicate directly with the device's storage. Common Use Cases: Flashing and Unbricking
Look for reset vectors ( b reset at offset 0), DDR init patterns, and UART debug strings.
