When I try to install firmware upgrade to the 9971 phone I get this error:
Download Status Error encountered: The selected file is not valid. MD5 Hash Value:
The MD5 Hash Value above does not match the Hash Value in the readme file.
The firmware I try to install is: cmterm-9971.9-4-2SR2-2.k3.cop.sgn
I have tried to download the files several times from Cisco. I have tried to install it from different SFTP servers.
Could the sgn file be corrupted on the Cisco server?
My server has CUCM 9.1
Go to Solution.
Please note the FW that you are trying to install has k3 in the end. For this to work properly, you will need to install ciscocm.version3-keys.cop.sgn on all of your CM server
Alternatively, you can download the complete ZIP foldercmterm-9971.9-4-2SR2-2_REL.zip and then unzip the same
Login to OS administration GUI of the CUCM and Navigate :: Software Upgrades >> TFTP File Management.
Click on upload files and upload all the unzipped files (one-by-one) in the directory. Use Directory as "/"
Restart the TFTP service
Note: Perform the above steps for all the CM/TFTP servers
