It looks like you're going to need to re-image the Olimex board. There are instructions online here: 

I'd recommend reaching out to your reseller for help.

Did this happen after updating the firmware?

This just happened to me last night as well. The printer became "offline" or "unable to connect" in the print queue interface during a print, then became unresponsive when the print was done. The wheel could be clicked, and would make a sound, but that screen wouldn't clear, even after restarting the printer. 

 

This did occur after a firmware upgrade.

Thanks for the tutorials, using the micro usb I re-installed the firmware and UM3 is OK

I posted this in another topic, and I'll share it here as well.

I found a way to unfreeze and update the firmware without reflashing the whole thing.  If you're getting just a "Print Failed" screen after a firmware update, you can clear the frozen screen by stopping and then starting the griffin.hmi.service through systemctl stop and start. 

 

Then I was able to move the wheel down to finish the upgrade to 5.2 without a painful microSD flashing. 

 

For further information, the root partition was full, which is what caused it to randomly stop responding, but was able to still print, just not respond or update logs. This was apparently related to my daughter accidentally updating the firmware to the step-up firmware before 5.2, and then I didn't perform the second firmware update to 5.2. 

 

My df -h is now back to 57% in use on the root / partition. 

 

Some logs that shows some of the 100% in use messages I was receiving.
