Click Finish, this will now have create a file called UCUdates.cab in the required location
Next step is to upload the .cab file upto the web server service on the Lync Front End Servers, this step needs to be completed for all FE severs in your Lync deployment.
From the Lync Management Shell run the following command:
Import-CsDeviceUpdate -Identity service:webserver:lyncserver.FQDN
-FileName "path to file just extracted"
From the Lync Server Control Panel, select "Cleints --> Device Update"
This will show the updates for Phones installed, approved versions of firmware and Pending versions.
Select the phone hardware type, select "Action --> Approve", this will allow ALL phone to update to the newly installed version of firmware.
If you wish to only update selected phones for "testing" select "Clients --> Test Device", this will show a list of phones addressed via either Serial number or MAC address that the update will be available for.
Once a Lync IP phone has been idle for approx 10mins it will check the web service to see if any available updates are available. If updates are available the phone will start the update process.
The update process generally requires the IP Phone to reboot, if PC are network attached via the Phone they will loose connectivity. So be careful when you approve the updates.
