Hi
I had the same issue today...
I formatted the Flirc and program it by myself with de commands from the original post and this worked. I don't now if there is something wrong with the config file or maybe there's a new Software for the Flirc since than and the File doesn't work anymore ¯\_(ツ)_/¯
If it's still a problem i can give you my config-file if you want.
best regards
