7372 locked to wrong country

[jelle_alten_606]

I have a zf7372 that somehow got locked into NL country code. Perhaps that happened when I took it out of the box and first thing I did was hook it up to a ZoneDirector with NL country code. Now I cannot change the country code back to US, which it was made for.
How do I unlock this? Factory reset and connecting to ZoneDirector will keep saying "wrong country code", CLI also states "illegal to change country code".
Is there a way to reset to "never initialized, pre-country-locked" settings?

rkscli: get countrycode
Country is NL
OK
rkscli: set countrycode US
illegal to change country code
