First, open the camera housing to access the main circuit board. Look for a set of four small holes or pads labeled VCC, GND, RX, and TX (these are the serial console pins). Do not connect the VCC pin —connecting it could damage your camera. Connect the GND pin of your USB-UART adapter to the camera's GND. Then, connect the adapter's RX pin to the camera's TX pin, and the adapter's TX pin to the camera's RX pin. Some cameras may have swapped labels, so be prepared to swap connections if needed. Once everything is connected, open PuTTY and configure it for serial communication: baud rate 115200, 8 data bits, no parity, 1 stop bit, no flow control. Connect the camera to power. Immediately after powering on, watch the terminal window—you should see bootloader output scrolling down. Interrupt the boot process by pressing a key (usually Ctrl+C or Esc ) when prompted. At the bootloader prompt, type cfgRestore and press Enter. This command erases all configuration data and restores the camera to its original factory state. The camera will then automatically reboot with factory default settings.
