2018 version S5, new owner, already had a Prusa. New firmware 5.8.2-R1, current version 5.4.27. Fails to verify by USB stick. Connected via ethernet to my computer but not sure how to get that to work. The instructions from Ultimaker lack detail such as specific menu selections or screenshots. Do push from the Cura to the printer? The firmware doesn't populate in the maintenance menu from ethernet connection, also can't get wireless connect to complete. I tried updates from Cura via Extensions/Update Checker/Check for Updates but said no updates available so I'm thinking that's just for Cura. Also tried connect the printer via the website but was asking for a code from "Ultimate Digital Factory" in the network menu which doesn't seem to exist on my printer.
Any help appreciated.
