Hi everyone! I just upgraded the firmware in my UM3 from usb, but the screen went black and still is. I tried rebooting it but nothing happens. The screen turns on but is still black. Anyone got a clue how to fix it? 🙏🏻

    I've been hearing about this a lot lately.  I'm not sure if Ultimaker understands this yet.  But everyone with the problem said it was fixed after a power cycle but still does it semi-randomly.  Try a few power cycles and give it a good 5 minutes each time.  If after 3 power cycles it still doesn't work, contact your reseller about the "unbricking procedure".  Actually I think they call it something else.  But it involves using a uSD card, putting a boot image onto it (not a normal file copy) and then removing a cover under the printer and putting the uSD into the circuit board under your printer.  There is a document explaining the whole thing.  Plus this tells you most of the steps but you have to get the right version from your reseller.
