The blind leading the blind here but I'm pleased to see it worked for you. I would like to know why so many have trouble with this.
Is this a clue to the problem --- The firmware update says its sys1.1. Does that really mean its intended for remotes with system 1.1. Clearly we agree that the update actually changes the app version not the remotes sys version. Maybe the reason it was a disaster for me and others is that I have sys 2.0.1 and already had a later App version ???
Can any of you experts shed some light on this, please?
As for the calibrate. I think it's to help set up the touch sensitive screen after an update. Label is for labelling buttons but I find it's far better and easier to do it using the RC edit software.
