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
[Download Status Warning] Error encountered: The selected file is not valid.
