I have been away from the DeviationTX world for years, now trying to get a couple of transmitters flashed with a working build. I do understand that there are no "new" builds, and I see the old 5.0 builds, plus a few nightly builds. I have "plain vanilla" Devo 10 and Devo 12E (not F12E), just added a 4-in-1 module, nothing else.
The old 5.0.builds do not support the 12E.
What is a "safe" nightly build to use, with a decent number of protocols for the 4-in-1 module?
