I promise this will be a very short one. This week I purchased 3 9971 with the camera in order to get ready for my rack rentals for CCIE Collaboration, well when I got them I noticed that the phones belonged to someone else(Duhhh!!).
I needed to do a factory reset on those guys, or at least be able to remove the ITL files.
My problem was that I could not do any of these because the Admin Settings was locked by a password. Of course you can remove this password but if only if your phone is able to get the SEP config from your CME (off course if you are using CME) – TCLSH procedure here https://collabengineer.com/2014/11/15/cisco-sip-phones-admin-password-removal-cme-tclsh-operation/
Using http://www.Google.com and the keywords “Cisco 9971 Factory Reset” I found many posts and the first one that shocked me the most:
Which the option for factory reset is completely discarded by one of our fellow members on the Cisco Support Community , don’t blame him, its a kind of interesting task to complete.
After that I found another one which deserves the mention:
In this case he was doing a 9951 but its all the same (except for the touch-screen and other features)
Enough with the talk and lets go to the action, here is what you need to do:
1- Unplug your phone
2- Press the # key
3- Now when you see the MUTE light turn on (RED)
4- Begin to Key in the sequence 123456789*0#
5- The phone will restart and then you will have a clean CP-9971 Phone
Check the Admin Settings and you will notice the Password is no longer there.
