UC520 Auth Fail on Software Pack 8.6.1 Using CCA 3.2.2.

Hi All,

I am looking for someone's assistance in what I am missing or doing wrong. After I upgraded my UC520 to software pack 8.6.1 and GB language my 7975G phone seems to be stuck in the firmware upgade mode.

I have performed several factory resets on the phone as well as contact Cisco TAC.

Cisco TAC did identify what the issue was howver I had to format my flash and lose all the data on the falsh card some when I did the upgrade again through the CCA it again has the same bug. I just want to manually get the phone up and running to current firmware that some with software pack 8.6.1.

The steps I have done are:

1) Format the flash to erase the bug that is stopping the 7975G upgrading

2) Copy the phone files across via Solarwainds TFTP server:

     a) apps75.8-5-2TH1-9.sbn

     b) cnu75.8-5-2TH1-9.sbn

     c) cvm75sccp.8-5-2TH1-9.sbn

     d) dsp75.8-5-2TH1-9.sbn

     e) jar75sccp.8-5-2TH1-9.sbn

     f) SCCP75.8-5-2S.loads

     g) term75.default.loads

3) enter in Conf T mode and update the TFTP-SERVER flash:apps75.8-5-2TH1-9.sbn for each of the above files

4) enter into telephony-service and enter no cnf-file perphone

5) enter the comand load 7975 SCCP75.8-5-2S.loads

6) enter the comand reset all

This should then reboot the phone and install the firmware files however my phone doesnt do anything. Have I missed any steps out?

Thanks

Brian

Post "debug tftp event" with "term mon", when power cycle the phone..

Hi Paolo,

I have opened a Cisco TAC case to get this resolved. However it seems that the phone can be seen as a CDP neighbour but it is not getting an IP address and is sitting at the Cisco upgrade splash screen.

Thanks

Brian
