I did reflash many times with different versions of BF. Nothing helped.
Untill yesterday, i flew my BetaFPV with OSD that i ordered of AliExpress and finally modded a camera to get the OSD. That worked like a charm. And my last pack i put insde my older Beta65s setup that gave me headaches, this time OSD works flawlessly. So wierd, cant understand how this could be, i didnt even connect it to BF.
But im really happy now i got 2 Whoops running OSD
Edit: Mystery solved, i realized that when i disarmed my Beta65s the throttle jumped up to 1999. On my Other Beta FC it did not.
Next question, why did the throttle value go up on disarm?
