[Machine dead after firmware failure to update]

Ultimaker 2 Extended +

Cura 3.1.0

I tried using the auto updating firmware within Cura and was presented with this message"

"Firmware update failed due to an unknown error."

 

Once that message displayed, the machine no longer worked. It will not turn on, no LED lights up, no illumination of the screen. There is a loud buzzing noise when the power switch is turned on. Cura does detect that the machine is connected, but no operations can be performed, and a firmware update attempt results in another failure error message.

 

What is the procedure to reset the machine to factory settings if the screen can't be accessed? Is there a manual hard reset procedure?

 

Thanks for the help!

I am having the same problem I hope someone can help
