Upgrading firmware IP Phone 7906-7911

I have factory reset the IP phone 7911 and i am not able to upgrade the phone. There is no ip phone 7911 firmware located in Call Manager Express.
I downloaded the following files from CISCO:
apps11.8-4-1-23.sbn
cnu11.8-4-1-23.sbn
cvm11sccp.8-4-1.sbn
dsp11.8-4-1-23.sbn
jar11sccp.8-4-1-23.sbn
SCCP11.8-4-2S.loads
term06.default.loads
term11.default.loads

How can i load the files in flash and register phone 7906-7911?

I copied these files to the flash card, but the ip phone continues to restart during the upgrade process. I noticed in the downloads section of CISCO, there is a new firmware for the ip phone 7911. The firmware is 9-2-1SR2.
Unfortunately after copying the files to the flash card and performing the configuration steps that you mentioned, the ip phone 7911 continues to restart during the upgrade process.
Can you give me feedback on this . Do i need to restart the router for the changes to be applied?

Thanks for the tip.
I am going to download 8.5.2 firmware and give it try.
Before i go ahead and TFTP bind the new files from 8.5.2, do i need to un-bind the old files? In other words do i need to use "no TFTP-Server" for files 8.4.1? Looking forward to your feedback.

José Méndez

Yes, unbind the 9.1.1 which would be the correct statement, right?

I forgot to ask you. Version of Call Manager Express we are using is 7.1. Which version of 8.5.2 firmware do i use. 8.5.2 or 8.5.2SR1 firmware?

José Méndez

8.5.2.

I loaded the firmware 8.5.2 and the ip phone 7911 upgraded successfully.
However when i used the command "load 7911 SCCP11.8-5-2S.loads" an error message appeared.
LOAD COMMAND ERROR.
How can i fix this?
Looking forward to your feedback.

I just found the solution.
Under "telephony-service" we have to place "cnf-file location flash:"
Thanks for your help.
