Devterm not working


I have a devterm that i ordered in april 2022. I had never been able to use it after assembling it. A lcd screen was sent then a main board after the lcd did not solve the issue. The mainboard was installed and it still does not work. I have an expensive doorstop and dont know what to do at this point.

I have reassembled it multiple times with same result. I have used batteries and usb c connector. The same result. There sound like a fan running but no video on lcd screen or external video screen using hdmi adapter.

Anyone have suggestions??

Thank you

Which Core are you using?

I am using core A-06.

Have you tried reflashing the micro-sd card or using another one?
