You can upgrade to the latest device packages from DOS like this:
PSUCli.bat -p cmf -d -dst c:\psu_download -all
Will download Common Services packages to C:\psu_download\cmf. Then install this way:
PSUCli.bat -p cmf -install -src c:\psu_download\cmf -all
I prefer doing these device package updates via CLI as this lets you actually follow what is happening.
