Q: I have updated the firmware in TellStick Duo, but want to downgrade again. How do I do that?
A: Download an older firmware (, stop the service as described in the guide, drag-and-drop the .hex-file to TellStickFlasher.exe (located in your TelldusCenter installation folder), and follow the instructions.
