File auth error (Load Firmware 7940)

[brunofalco]

Hello

I would like to help one of you for a problem I'm having to update the firmware of a Cisco 7940 in the cucm 8.

I have upgraded the files cmterm-7940-7960-1-sccp.8 2.cop.sgn, 7940-7960cmterm-sccp.8-and-a-2SR1.cop.sgn cmterm-7940-7960-SCCP. 8-1, 2SR2.cop.sgn.Once uploaded, they generated an MD5 hash key.

Then I'll put in the Device Defaults and Load the file. (P00308010200.loads)

However, when the phone is started, the following message appears:

TFT _P00308010200.loads

File auth error

What does this error mean? Missing some process?

thank you!

Hi Bruno,

For the 7940/60's you are hitting this install note due to the age of your existing firmware;

Note

You cannot upgrade to firmware release 8.1(2) directly from firmware release 8.0(10) or an earlier release. You have to upgrade to firmware release 8.1(1) first, then upgrade from release 8.1(1) to release 8.1(2).

So to rectify this issue you will need to download the 8.1(1) firmware from CCO and install it on CUCM

(upgrade phones) as your first step. This will then allow you to move to the desired 8.x(x) firmware build

Cheers!
