I got my board 2 days ago and First I flashed my SD card and loaded the image using Balena Etcher Then I tried to do the headless mode but It didnt detect /dev/ttyACM* and then I tried to connect to the Monitor through HDMI and I didnt got any signal. Any help?

Please stop guessing… Just get the usb-ttl and dump the log is the most precise way. Or find a x64 ubuntu 18.04 host to flash your board with sdkmanager. You are not the first one hitting nano cannot boot issue. I already saw lots of cases here. Just follow what I suggest to save your own time.
