I have a CUCM 8.5. I have a 7961 phone that fails to upgrade after a factory reset. I have confirmed that the file term61.default.loads is in the cucm tftp server. The phone powers up, goes to update, tries to find term61.default.loads, and resets after a bullet icon in the left hand corner of the screen. The load version is SCCP41.9-1-1SR1S.

Try installing 8.5(2) and then updating to 9.1(1) after that. There was a code signing key change and the burned-in image probably doesn't trust the new code signature.
