[Could not upgrade firmware. Contact support.]

Just in case you thought that v1.2.3 solved the problem: Still the same problem.

Uhm ... hello? Do I only get an answer if I post twice every time?

Sure. But I haven't used that software before. A short explanation and a date and time would be good. :-)

Any idea yet? Anything I could do to help?

v1.2.2 on both operating systems.

I didn't know that you are an "one man army".  :o  My sincere apologizes! If this is the case, then you are actually doing a great job!

 

I already tried that suggested utility without any success. The device is enlisted in Windows 8.1's Device Manager as bootldr but still the GUI can't establish a constant connection. It always switches forth and back. Same under Mac OS 10.9.2 by the way.

 

Anything else I could do to help you with the troubleshooting?

So pictures are more important than a buggy Flirc () ... I think i should post that on Amazon ... -.-

After unplugging the working FLIRC once and plugging it in again it stopped working. The GUI of v1.2.2 switches between: "Could not upgrade firmware. Contact support." and "Bootloader detected." Also there is a line saying: "Bootloader v-16.-16". It is not possible to "Force FW Upgrade" under "Advanced".
