8945 Hangs Up During Firmware Upgrade

[Laurent Protti]

Hello,

Running CUCM 11, I have a 8945 phone that is stuck during the firmware upgrade.

The phone already has firmware SCCP894x.9-3-4-17 so according to the firmware relase note, the upgrade to  SCCP894x.9-4-2SR3-1 should be possible.

when the phone is stuck it's still pingable but no web access.

Any insights on this ?

thanks and best regards

what exactly do you see on the phone?

Hello, here's a screen shot. The light on the handset flashes a few times then stays on and the displays is stuck with the message "upgrade in progress"...

Did you carefully read ''readme file''? 

make sure you meet what Cisco says here.

Firmware Version 9.4(2)SR3 for Cisco IP Phone Models 8941, 8945

The 9.4(2)SR3 firmware supports Skinny Client Control Protocol (SCCP) for the following Cisco IP Phone models:

• Cisco IP Phone 8941
• Cisco IP Phone 8945

The Cisco IP Phone 8941 and 8945 support a new "secure by default" feature from 9.3(1) onwards, which requires devpack 8.0.3(24049)/8.5.1(14070)/8.6.2(22030) or higher installed on 8.x Cisco Unified Communications Manager before phones are upgraded to Firmware Release 9.4(2)SR3. If the correct devpack is not installed first, the phones cannot successfully register to the Cisco Unified Communications Manager!!!

Release 9.4(2)SR3 can only be upgraded from 9.3(4) and later. Releases prior to 9.3(4) have to be upgraded to 9.3(4) first.

Hello, devpack 11.0.1_23068-1 is installed, phone has firmware SCCP894x.9-3-4-17 so it complies to requirements.

well, forget about it... I believed that the phone had firmware 9.3.4 because it was stated in the phone load field in Call Manager, but in reality, it had an older firmware... so upgraded to 9.3.4 and then I was able to upgrade to 9.4.2...

sorry for the trouble
