Help following upgrade to 3.12

[canpandave]

Hi all, I am new to the group and have had my Phantom for a few months. I upgraded to 3.12 and now I get an error that I have to recalibrate the transmitter. I do this but channel A seems unresponsive and I cannot get the error to go away. It is Error(29)

Can anyone help?

Thanks

Dave

Well it looks like the problem was the Transmitter, I bought a spare after breaking the left switch.

I changed back to the old one, recalibrated and voila, back in business
