I’m trying to remenber but think you connect a Usb keyboard and a monitor directly to the Nucleus then there is a blank screen you press Enter and type something and that resets it.
If you get a prompt you can reset the network settings. The Nucleus is a computer with its OS on a hard drive.
What do you see when you plug a monitor on and turn it on?
I don’t have it as it is on its way to a new home. When I got it I hooked up an hdmi display and bluetooth USB keyboard. I recall it had a blank, black screen and I typed something like “root” and it ended up factory setting
I wanted to help out new owner in case it needed to be done.
