So I found this post:
And so added ,“country”:“IE” to the end of my config.json file by editing it on my laptop. Then replaced the microSD card in my device and rebooted.
It now shows the four green LED flashes of death after a few minutes and repeats. Even after 10 minutes there is nothing seen on Balena Dashboard for this device.
And if I check if my local WiFi router has seen the device (I knows its MAC address) I see no entry.
Also I have now lost the ability to login locally to the device as root.
