Hi,
are you able to check DM920 authenticity using the plug-in and https://dreambox.de/en/authenticity-test page?
When I pasted the code given by the plug-in installed on my box, the result was strange, not recognized model name, not matching S/N (on my box I have something like "DM920zzzzz" and the online check returned xxxx-yyyy), only the MAC address was valid.
Did you manage to get the correct authenticity check results using the online S/N check on Dreambox.de page?
