@Tech@ZWO#58949 Hey, thank you for the reply. Just a few minutes before you replied, I managed to flash the firmware on an old Windows machine.
And now I see another issue. When I use the Ekos or any other software to do some exposure, the console indicates the exposure has failed. When I enable the stream, all I see is a blank black screen.
Is my 120mm dead?
Thank you again
After I flashed the 120mm with compatibility firmware, it immediately started working again.
