I have a bunch of brand new 8821 phones. After pulling them out of the box and manually adding a Wi-Fi profile, they now have the Wifi and Admin screens greyed out. They have not yet communicated with a Callmanager, so they would not have been told to lock themselves down. How do I unlock these two screens without doing a full factory reset? I'm thinking they have a CTL file that came from the factory (Seen that on allot of newer model cisco phones) that is preventing them from registering to our CallManager. But I cant delete the CTL without getting to my Admin Settings.
