[cisco-voip] Trouble upgrading 7960 phone from P00308010200 to P0030801SR02 (or downgrade to P00308010100)

[Lelio Fulgenzi]

Thanks Wes. 

I downloaded the non-working and a working cnf.xml file and compared the two. The non-working one was 9KB and the working one was only 7KB. I recall memory being an issue on the 7940/60 phones so I compared them line by line and saw that the 9KB file had a number of IP phone service subscriptions. We removed a few of those that were not needed to reduce the size to about 8KB. This worked and the phone upgraded. 

The phone in question was a colleague's phone who was doing a lot of work with UCCx, so it's not likely we'll see this in the wild, but we wanted to make sure what was causing the problem to be sure.

I'd bet on the phone choking in something in the config file. Perhaps take the XML file edit it down to only include the <loadinformation>…</loadinformation> with complete details and put that on a TFTP server for the phone.

We have on 7960 that I'm having trouble upgrading and I don't know why. I'd like to understand why and hopefully resole it in the event we get more of these when we do our campus upgrades. 

There are other 7940s and 7960s that are on the same VLAN and same switch which have been upgraded fine. I can't even downgrade from P00308010200 to P00308010100. I believe this means I need to focus on the phone itself rather than anything else. 

I have done a factory reset and this did not help. The phone simply cycles the reboot process over and over again. On the screen flashes the normal process, but it lists only P00308010200. In a nutshell, on the screen I see: 


    1. Configuring IP 
    2. Configuring CM List 
    3. Configuring VLAN 
    4. Configuring IP 
    5. quick flash of something, I think relating to the cnf file 
    6. TFTP P00308010200. loads 
    7. Configuring VLAN 
    8. Configuring CM List 
    9. start at #3 again... 

Is there something I can do on the TFTP server to erase the configuration of this phone? I only recently uploaded a few firmware files so the TFTP server has already been restarted. 


Thoughts?
