Devo 12S Throttle stick? Cant turn on TX

Hello, I have a devo 12s and its set up to fly a DJi F550. I have been using it for about 3 weeks and its my first RC toy. I was stuffing around with some random alarm setting to ensure I couldn't have my throttle hold and manual mode switch enabled when turning on the TX.

I turned the unit off and then attempted to turn it back on again but now I get the "throttle stick" warning and my throttle is all the way down?

I have tried all switches and combinations but still cant get past that warning.

Is there a way to reset it completely?

Thanks

Yes, just what came with it.

I just upgraded with the DefuSe program and file from the Walkera website but it seems to have kept all the old settings, so I'm still locked out

Ok all sorted, I figured out how to erase it all.

Its unlocked now.

Thanks for your help.
