How to install new firmware in Skype for Business

Download the CAB files (here). Place/Move the zip file to your desktop (or temp folder) on the Front-End server. Now open the Skype for Business Management Shell and go to the directory

Now run the importCAB.ps1 script

After import go to the Skype for Business Control Panel

Go to Clients, Device update.

In this list you will find the new firmware files. The files are now on pending (normally you will see other firmware files but i didn’t had the time to add these in my lab).

Now select all files with version and go to the action menu. From there select approve

Now check the column Approved Version, you will see the new firmware listed.

Now to see if phones are picking up the new firmware you can check the log on your Skype(lync) fileshare.


It can take up to 24 hours to check if there is new firmware for a phone, you can always restart the phone. At startup it will check for new firmware.
