Found this nugget of information on Cisco NetPro forum: The next CUE release for UC500 will be 3.0.3.1 which is planned to available the first week of March.

For UC500 there is currently only one CUE release available as of now which is 2.3.4.1. The next CUE release for UC500 will be 3.0.3.1 which is planned to available the first week of March. The only option for upgrade to this release (3.0.3.1) from the first release (2.3.4.1)is to do a back up of 2.3.4.1 first , then do a clean install of 3.0.3.1 and then restore this backup.

If you are using 2.3.4.1 then you can use "software install clean ...lang.pkg" and select the desired language.

If you are using 3.0.3.1 then you need to use the CLI "software install add...lang.pkg" to change the language. let me know if you have any questions.
