Most Logitech revue boxes update automatically but we have found that for some units it is necessary to force the upgrade. The procedure for this is as follows:
1. From the Revue, head into Settings>Apps>All.
2. Search for Google Services Framework.
3. Once found, tap on it and choose “Force stop.”
4. Then choose “Clear data.”
5. Back out of Apps to your About page in Settings and check for the
System update, it should then download the update.
