I am having trouble trying to update my Ultimaker 3 Extended printer to the latest firmware. So far, I have done the recovery steps in the event it was bricked, but no luck. The wireless option isn't working either and it's either stuck on downloading new firmware, or downloading firmware check has failed. I have tested the second untimaker extended. So far, its fine! No issues save for grinding filament, but that's an easy fix.
Right now, I am trying again to update it via USB after another recovery, but it's giving me a "Check for new firmware update failed" message.
