If you have an older piece of hardware (that's still DVT 1.4.1.):
connect device -> "Firmware update" -> "Load test firmware" - this way, you will have the firmware with which the new sabre mode is available. Each time, you connect your pocket boxes with this firmware, a message box will inform you that it does not match the latest publicly available version. You can ignore this and go on with the test version.
This tutorial will be updated soon...
