Hi,

You are correct.

You need to go via 9.0.2, however it need to be the unsigned version.

See the 9.2.4 readme http://www.cisco.com/web/software/282074289/90710/cmterm-6921_6941_6961-sccp.9-2-4-3-readme.html

Can you confirm that you are using the unsigned 9.0.2 firmware

The unsigned firmware was the hint. I used a 9.0.3.a unsigned. Works also. But what the hell is the reason for this? Why must used unsigned firmware only at this point? Doesnt understand Cisco.

Hi SA,

The firmware for the 6941's needs to be at 8.5(4) as a first step before going to 9.0(2) and then

you must use the "unsigned" files to move to 9.0(2) 

Installation Upgrade Notes

#

Direct upgrades, using unsigned load files, are supported from firmware release 8.5(4) to 9.0(2). You can use the following firmware release file for these direct upgrades:

#

cmterm-6921_6941_6961-sccp.9-0-2-0-uns.cop.sgn


#

Note After  you upgrade from firmware release 8.5(4) to 9.0(2) and for subsequent  firmware releases, you can upgrade or downgrade only to signed firmware  releases.


#

Before You Begin

#

Before  you upgrade from Cisco Unified Communications Manager (Unified CM)  7.1(x) to 8.(0), you must upgrade to firmware release 9.0(2).

##

Installing Cisco Unified Communications Manager

#

Before  using the Cisco Unified IP Phone with Cisco Unified Communications  Manager, you must install the latest firmware on all Cisco Unified  Communications Manager servers in the cluster.

#

To download and install the Cisco Unified Communications Manager version, follow these steps:

#
