Privileges have a password “A710” not enough.
Example, for my Sierra EM7305:
=== activate FCC_AUTH ===
at!entercnd="A710"
OK
AT!PCFCCAUTH?
NV setting: 0
Auth enabled: 0
Lock state: 0
OK
AT!PCFCCAUTH=1
ERROR
AT!OPENLOCK?

AT!PCFCCAUTH?

Thank you for this post, I can’t get into the “engenering” mode with at!unlock, I think this may be a challegene-response sequence. As it changes with every at!unlock? command.
