Report What happened to my Flirc after failed upgrade? in Firmware Bugs Posted April 20, 2020 5 hours ago, EaZyCheaZ said: I have the exact same error message and output on my test. I just bought this unit in march. I finally got my new man cave assembled and went to program my remote to the flirc and it's dead. Hi man. I guess each case will be very individual, but I got mine fixed quite simply by moving Flirc into a different USB port and manually flashing older fw with flirc_util.exe upgrade dori.release.bin. I had to dig for an older release of fw here on forums, those are not readily available somewhere. After that it was correctly recognized by GUI, and properly flashed up-to-date fw, so I moved it back to the original USB port and I'm happily using it since. So I hope you're comfortable with command line and that solution will work for you too.
