I had quite the ordeal figuring out how to update the firmware of my SPF3 FC . Turns out the issue was a faulty mini USB cable the whole time. Before updating the firmware, my quad would arm and run just fine. I needed to calibrate everything using CleanFlight, which resulted in updating the firmware. I'm using CleanFlight 2.1.0 I flashed firmware to the F3 flight controller, and after that, the FlySky doesn't seem to work anymore. I bind the transmitter and receiver again. I can confirm with "RX" symbol in the corner of my transmitter display. When I try to arm the quad, nothing... when I try to read values under the "receiver" tab on CleanFlight, I get nothing... and yes, I have the battery plugged in. It seems the transmitter is not binding with the receiver correctly since I'm reading no values on Cleanflight.. but then again, I can see the RX on my transmitter display. Regretfully, I did not save the state that the FC was in before flashing new firmware. Any clues of where I could have gone wrong? And how to fix this?
