Hi and thank you for your answer.
I have actually tried this. An ethernet cable with internet is connected to printer and it doesn't seem to have any trouble downloading firmware it's when it is trying to install the firmware it fails. So I think I can confirm that it has internet access.
Also when I put the two files on memory stick they don't show up. The printer doesn't recognise the files. So I can't do that either I'm afraid. If I download the 5.3 version it recognises it and I can choose to start installing it but it fails to verify it after a couple of seconds.
It doesn't seem to be any way to get a new version of the firmware in, maybe I'll need to get a new motherboard?
Welcome to the Utlimaker Community 🎉
I recognize your error.
You'll have to connect your printer to the internet because it doesn't know the date without it.
You can find more about the bug here: https://support.ultimaker.com/hc/en-us/articles/360014745220-Firmware-installation-failed-to-verify
You can find the files you need to update to the latest firmware here:
Since you are on a firmware version older than 5 you'll need to read carefully and install a stepping stone firmware first.
Let us know if you are still stuck, than we can explore other troubleshooting directions.
Hope this helps! 🤞
