Hi, You need to install the corresponding serial port,
You can refer to: https://www.geeetech.com/forum/viewtopi ... RlcFtWdCG4
You need to close other slicing software when uploading firmware.
Avoid occupying ports,
You can restart the computer to see the situation.

You can download the firmware on the official website: https://www.geeetech.com/download.html?download_id=36
Then upload it using the firmware toolkit,
