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

[Kin Wai]

It's running on 6.0.2 now, I'm trying to upgrade to 8-5-2. By the way, it's
a 7970. According to bug toolkit, there's some documented bug which mention
it happens 'occasionally' but for me the hit rate is 100%. 

 

With a factory default (I tried the way using 1234567890*#) , it's not
working. As mentioned, after it boots up, it connects to the new callmanager
successfully without upgrading to the latest firmware specify inside
default.loads. When I look at the firmware field on the phone, it shows
term70.default.loads. 

 

I have yet to try  the (3491672850*#) method so far. Seems like I'm facing
multiple issues here. 

 

As customer is moving from 4.0 to 7.1, with the old firmware(after the
factory default) I guess I will lose some features?

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
