[cisco-voip] Trouble with upgrading firmware due to firmware bug

[Ryan Ratliff]

Is your phone running 6.0.2 now or trying to upgrade to that load and  
failing?  If it is running 6.0.2 now what version is it trying to  
upgrade to (specified ind device defaults)?

When you do a factory reset the phone will look for the term7.default  
file on the TFTP server it gets from DHCP and then upgrade its load to  
that specified in the defaults file.

Hi Folks,
I’m having trouble with this firmware load “TERM70.6-0-2-0S”. In the  
current environment, it’s DHCP based. I manually disabled DHCP and  
point the TFTP server to another TFTP server (new callmanager with  
latest firmware)

It seems like the phone is stuck with a reboot loop with “verifying  
firmware” showing on the screen. It didn’t download the latest  
firmware at all.

The only workaround I can find so far is to either do factory default  
else if factory reset. So far I tried 4 of them, none of them manage  
to retrieve the firmware successfully by itself without any user  
inference.

Something interesting is occasionally when I do a factory default on  
the phone (the step with 1234567890*#) , it will connect to the new  
callmanager without upgrading to the latest firmware, instead it boots  
up and connect using term7.default(the default firmware load). Is this  
normal?

In a successful example, after the factory default command, it will  
download the latest default firmware load, follows by the latest  
firmware load.

Anyone face  similar problem before? Having to factory reset/default  
is really not something I want to happen during the migration day or  
before the migration day during late evenings.

Regards,
Kin Wai
