Hey guys. Is there a way to downgrade our 1140 firmware on specific phones (2 of them only) on a 5.5 system? Basically, version 0625C4L works with our Bluetooth headsets and 0625C6J does not. I would like to get our C6J sets back to C4L for our Help Desk so they can use our Plantronics Voyager headsets. Thanks in advance.
Supposedly it is possible with Element Manager or a switch command, but I don't know the path or command to do so and I am having trouble locating it. I have done a TFTP set by set upgrade in the past so I am familiar with that as well.
