Never had a problem with ota flashing. I had gone to ethos suite to flash radio and download some receiver updates. When I went to update, in the menu, there was no flash option for anything. So I deleted the bin file and it fixed it. Had to re do global variables and radio settings, but it worked.
I went back to ethos suite to back up my radio and install lua scripts for my new recieivers.
Then when I went to install my floss, it would recognize the sensor, but no data. Tried 2 sensors I gad and a new one I just got, nothing, didn't work.
Later, I'm going to delete the bin file and see if it solves the problem, I have a strong feeling it will.
Anyway, I think ethos suite corrupted my radio both times.
It's the only 2 times I've had issues with frsky in 10 years and just in past 2 weeks.
