After upgrading CCM for DST, etc patches we have 1 7970 model phone that is not coming back up. Servers were upgraded Friday night and on Monday morning, one of the phones was still showing as Not Found in CCM and when we went to the phone it had Upgrading on the display still , all weekend apparently. The phone did not respond and there was no activity on the display so appeared it was locked up or something, since a majority of the phones were back up and working shortly after the updates were finished on new firmware.
We hard booted the phone (removed power/inline power) and it goes to the same upgrading screen right away.
We tried the factory default key sequence also a few times with no effect.
Any way to get this phone back operational? Unfortunately, the phone is out of warranty and not under a contract so I'm not able to get a cisco case open on it to get it replaced until a contract is purchased on it.
