I have read and tried all the stickys on flashing the firmware and OSD. I followed the sequences to the letter, multiple times. Each and every time, I get the same error message, that the communication fails. Just to test the cable and connection, I have tried SEVERAL different USB cables, and different computers, both windows and linux machines. All drivers and program updates have been installed. No luck, same error. The bird is a Flite Test edition, running 1.0.0.42 INTL ; API 1.31 ; FC 3.1.7 BTFL. This is causing me some SERIOUS frustration. I would really appreciate some help on this...
