With v4 or newer, you can use a system setting to lock the device at a specific OS version. The system will never show a update to a later OS!
The setting group is “global” and the value should be the latest OS that should be installed on the unit. For the key, see the table below.
This setting needs to be applied from a EEM system or using the MaxGo Manager or Staging apps. There is not setting in the System Update itself.
