l Cannot log in to the Crestron Home Setup app or web XPanel interface.

Possible Cause(s)

Improved security features were incorporated in firmware version 3.000.0419 that interfere with
backward compatibility.

Corrective Action(s)

The following corrective actions can be performed:
l Reset the Passwords and then Reboot: The password reset procedure is unobtrusive and
should be attempted first.

NOTE: If the Advanced User password or User Interface Device password is set, the
Crestron Home processor must be factory reset.

l Factory reset the Crestron Home Processor: Factory reset the Crestron Home processor
only if other corrective actions do not work.

l The Admin username and all other users are removed from the system.
l When the passwords are reset, the system displays a prompt to enter a new Admin
username and password.

manually.
