Left it for a couple of hours, it just sat there, and then SoCal Edison solved the problem for me. Came back ok.
Same situation here.
Upon first update to 5.3 on my UM3 from 5.2.something, it reboots with a scary blank screen too.
A power cycle boots the machine right up and it says firmware upgraded to 5.3 successfully but yet there is another newer version of 5.3.0 to upgrade!
So, there it goes upgrading the firmware again....
A nail biting minute of button blinking green and blue and..... it says new firmware available. Current 5.3, New 5.3.0.... Install or Ignore? Again?
I've clicked on Install and it seems to go into a firmware install loop again unless you click on Ignore.
The printer seems to work fine on 5.3.... and it's connected to Digital Factory. I'm happy for now.
An update and feedback for those who are experiencing the same symptom and not sure what to do after.
You can just ignore it, the printer thinks there is a newer firmware for whatever reason.
it's because the upload script removed the date pert of the filename as with the s-line releases, so we renamed so that it shows "5.3.0" in the update message instead of just "5.3".
It it's the same FW in this case, I promise.
I'd say give it a power-cycle (flip the power switch to OFF - wait a good 5 seconds and then back to ON)Edited by robinmdh
let us know it it boots up!
The time it takes is dependent on what you had installed before, but it should definitely be done inside 15 minutes.
