Hi there.

I am a little clueless, and I am fairly new to this topic. I tried to flash a newer version of betaflight to my flight controller and after I did that (felt successful at first, did recalibration) later when I wanted to reconnect to my mac and betaflight I had the following situation:
– flight controller blinking red only. (was different before with other lights/patterns)
– Mac doesn't seem to recognise any device in the usb port.
– betaflight configurator doesn't seem to recognise anything either

So I tried to get it to DFU mode, but when I plug the fc in with the boot button pressed nothing happens in betaflight.  I see no reaction on my mac when I plug in. The flight controller has no lights at all when I plug in with boot button pressed.

What could I do to fix my flight controller?
It seems I cannot access it in the first place...

Many thanks!

Does anyone have an idea on what I could try to do? It's a Tiny Hawk II and I am using mac.
Is it even possible to flash my flight controller when Betaflight Configurater does not recognise DFU mode?
