Updated from 4.3 to 4.4, Lost Settings, Can't Setup Spektrum RX again

I have a Source One V5 quad that I built. It was working OK-ish with Betaflight 4.3 and my Spektrum RX and TX. However, I recently flashed the 4.4 update and lost all the settings. I've gone back through many Spektrum and Betaflight articles and videos, but I'm stuck, unable to get Betaflight 4.4 to see my Spektrum TX and RX.

Does anyone know where to find the updated setup and troubleshooting steps with Betaflight 4.4 and Spektrum? Am I just the unlucky one who ran into this issue because other folks use ELRS, Crossfire, or other RX and TX options?

Are you using the defaults for the firmware flash? I think Spektrum protocol isn't included by default anymore -- CRSF, GHST, and SBUS are the default. You need to add it to the list of protocols in the firmware flash screen.

Yes I did use the defaults, thanks. I will go back and try another build. I would have thought that if that was missing that Betaflight would not show it as an option.

I did seem to miss getting all of the Spektrum stuff added to the original flash image, it seems. Making a new image with only the Spektrum options added seems to be working. Thanks again u/kevin-sumner for the point in the right direction.

I have the same problem with my IBUS. Was working prior to upgrade post upgrade bupkis

So I fixed my problem. It was something in the omnibus 4.4 firmware. Once I downgraded to 4.3.2 everything started working for me again.

Try downgrading your firmware and do a full chip erase. Even with the some of the presets you'll still need to set somethings up again.

I solved it by building a new image from scratch with the Spektrum options selected.
