Ditto the above.
Same issue here, powered down and powered up and all was good. Now to fly it and see if it really worked…

A question for you all. Do you each have dual screens or single screens? The update should progress without having to pull power at 99%, though you're doing the right things in the end. Just trying to understand if there are any commonalities to it not finishing on its own.

Thanks,

I had the same thing happen to me today. Single screen. Got to 99% and stopped. Called Dynon support and left a message. They called me back within a few minutes and said that yes, sometimes this happens and go ahead and power down. Did that and on subsequent power up, transponder showed that it had been updated to the latest version.

Look at the bright side. We're all getting very consistent results from our Dynon systems.

Same here- stuck at 99%. Had to cycle power to Xpdr to correct. 1,2&5 reboot of display did not correct. I have a single display.

I also have two screens but learnt a while back that it’s better to only have one powered on during software updates. After I had sorted out the first screen and transponder I powered the screen down and powered up the other. I applied the update and after it had finished it came up with an error message for the transponder. I powered up the other screen and the message went away. All seems to be working fine now.
