@t3p3tony Double clicking the reset button turns it into:
On windows: serial port changes to "Serial USB unit (COM4)" and under USB-units there's a "Duet3-Mini5+"
On Linux: a mounted volume named DuetBoot shows up with the 3 files (CURRENT.UF2, INDEX.HTM and INFO_UF2.TXT).
No, can't connect in any way.
@t3p3tony I've already tried that, it copies the file, resets and it's back to square one, can't connect to it

@phaedrux I've done that and gotten it approved but one question remains.
Do I dare to ever run an update on the new board if it might brick it?
It seems like figuring out what happen to my current board should be a high priority.
What do you think?
@phaedrux I bought it from the Swedish distributor RepRapPro.me and it was sent on October 15 (it has taken me a while to make the new wiring loom).
@phaedrux What about I try to wipe everything (including boot loader) and reinstall from scratch?
@phaedrux Yes, I've tried both YAT from windows and PuTTY from Linux. No response.
No light on any ethernet LED (the port worked fine before my "update").
LEDs on board with only USB connection (no 24V):
3.3V solid green
5V solid red
Status, slow stead blinking red

@phaedrux I followed your instructions to the letter but no change
It behaves exactly as in my first post.

I have a new Mini 5+ Ethernet.
When I got the board I connected USB power and Ethernet cable, everything was fine.
I then ran the online config tool to the best of my ability, checked "update firmware", saved it and then used the web interface to upload my new config.
That seemed to hang and after that, I can't connect to it (Ethernet or USB).
The press "reset" twice, get a mapped drive and upload firmware works but after the reboot I'm back to no connection. I've tried several different firmware versions, no difference.
The LAN interface does not do a DHCP request.
The USB port shows up as Duet 3 motion control electronics (COM3), but I can't connect to it (Pronterface 115200 baud).
Any suggestions of what I should try next?
Regards
Soren
