Connect your device to your computer using a USB-C cable. Please ensure the cable supports data transfer and is not limited to power delivery only.
Once the device is securely connected, find and press the "Install" button provided below to initiate the update process.
After clicking "Install," check your computer's serial ports list. Your device should now be visible in that list.
If you're unsure which serial port belongs to your device, disconnect it and then reconnect it. Watch the serial ports list to see which port appears or disappears—this will confirm the correct device.
If nothing happens, check that there is no application actually using the serial port you are selecting (i.e. Fangstr, Serial Terminal).
