I was going mad until I found this post... :)
But now i know I am not mad.
I have been using a Flirc for a year or so without any problem. I got some new equipment and reprogrammed my Harmony One and updated to Flirv 3.0.
Most works fine except that the Harmony One can no longer control my Raspberry Pi based OpenElec (XBMC) installation.
How can I downgrade the firmware in the Flirc?
Edit: It seems to work for some key presses, but extreeeemly slow... I would like to try reverting to an older firmware but I don't understand how.
