Hello pa28pilot

Welcome to legitfta. I have loaded this firmware several times rolling back and them forward without any issues. Are you updating using the Internet update or by USB??Others have also update their units without problems. This is first time we heard of this issue. Probably something happen while in the update process??. So I will suggest to do a factory reset before and after the updating process. You can go ahead and do the process again and post results. If for any reason you come up with the same problem you can always roll back.

Again, Welcome to legitfta!!
