When I received it I programmed it and it worked fine. Had to reprogram a few times just to figure out how it worked on different remotes (ie:, on MCe remote, not very well due to the MCE remotes quirks).
Used the flirc for a week and it was fine, though a little sketchy at times, would stop working and then work fine again 2 minutes later, I put that down to issues with the Kodi setup waking up from sleep or something.
One night it acted up in that it would only respond to commands from the remote if I held the remote right up and pointed it directly at the flirc. Next morning it failed to work at all.
So then I tried to re-program it and this is the point at which it failed to respond to any remote. My thoughts too were that it would be very unlikely that a device that worked fine would suddenly stop working, hence my request for help/advice on this forum.
My retailer has agreed to replace the device. Maybe it was dodgy all along and the intermittent failures were not just teething issues and sleep problems with Kodi, but evidence of a flirc that had a hardware fault all along.
