ah it gets stranger as just come across this
Well that’s for inav, not betaflight, seems not very well supported FC (though cheap!). You got teh full or the basic one BTW?
Does it look OK on betaflight configurator? i.e. move when you rotate, etc?
Full and nothing no motor input in BF …
Not really understanding a lot of the above but reading through it it looks like people are flashing with the Flywoo software. wondering if its worth a go 
Flywoo no good and tried an earlier version of what it should be 
Put it on the naughty step and have a curly wurly. Then come back to it and reflash 4.3.0 JHEF411 and post the diff all
Can you post all the text? Or is that it?
Thats it
Can you type ‘get motor’
My bad
Entering CLI Mode, type ‘exit’ to return, or ‘help’

I can’t remember, but why did you change the fc? Was it because of a crash?
Its been that long ago now I cant blood remember myself 
You thinking it might be the esc ??? have I gotta start looking at how to test an esc
Best way is elimination. Using another esc or fc.
But cheer up, I just crashed by 3" into my pond
Yah im sure the esc is good checked with meter
