Cisco 7841 IP Phone Firmware Update

[mike.balik@otticksolutions.com]

Hello All,

I'm looking to see if anyone can offer assistance on updating firmware on several Cisco 7841 phones that I've inherited.  I'm looking to update the firmware without using Call Manager (need to get to 11.0 to use phones with Spark).

Phones are currently running various revisions of 10.1 firmware.  I know that in order to update to 11.0, the phones must first be running 10.3.  However, I cannot get the phones to get to 10.3.  I have several phones running 10.3 that I successfully updated to 11.0, so I know my TFTP server works correctly.  I can see in my TFTP logs that the phones running 10.1 connect to the TFTP server and download the XMLDefault.cnf.xml file, but then the phones do not process the .loads file with the firmware version in it.

I'm not sure if I'm missing something on the phones running 10.1 - do they need to go to a different firmware rev other than 10.3 prior to updating to 10.3?  

Again, Call Manager is not in the picture here.  The phones were previously used with a Call Manager setup that is no longer in existance.  Phones have had all settings reset to factory defaults.

Any suggestions on what to try or info would be greatly appreciated before I end up having to replace them.

Thanks!!
Mike

can you upgrade to a 10.1 10.3 intermediate firmware first?  10.2 for instance

please rate if helpful

I'll double check, but pretty sure I tried 10.2 as well and had the same results.

Double checked everything with 10.2 and still the same results.

The phones are running various versions of 10.1, but this particular phone is running Sip78xx.10-1-1ES3.

Below is a log file sample from my TFTP server when the phone makes contact.  After this, there is no further activity.
