Followed up with Naray directly.  When using CUCM 11.x or later only COP files signed with the RSAv3 keys can be installed.  There is no RSAv3 signed version of that COP file so the zip file version has to be used through TFTP file management.

It looks like your CUCM does not have the RSAv3 key file installed -  ciscocm.version3-keys.cop.sgn <https://software.cisco.com/download/release.html?mdfid=284603137&catid=278875240&softwareid=282204704&release=COP-Files&relind=AVAILABLE&rellifecycle=&reltype=latest>.

New RSA keys are used to sign Cisco Unified Communications Manager releases and other updates such as Phone Firmware, Locales, Dialplans, other cop files. This cop can be installed on any UCM or see README for versions needing this cop.

After you install this file (no reboot or restart required), try to install the phone firmware again and it should work.

I am facing phone firmware upgrade issue. On one of the 7961G phone, the time is not correct. In Active load (Device > Phone) i can see unknown. This phone firmware version is Jar41sccp.8-3-0-50.sbn while other phone which is showing correct time is jar41sccp.9-4-2ES9.sbn. when i searched about this firmware. the phone cant upgrade directly from 8-3-50 to 9-4-2. for that i have to do intermediate upgrade to 8.5.2 (cmterm-7941_7961-sccp.8-5-2.cop.sgn). when i tried to upload the file to cucm (install/upgarde option). i am getting the following error.
