Hello guys, I almost drop everything because I can't connect my spark to anything (mobile device, laptop, etc) when I press the power button on the spark no beep/beeps coming out from it. I've tried almost all videos in YT with no luck... I have installed the assistant 2 and it's running fine I guess.. the issue is that when I connect the drone I got the error of "unkown device". I tried to find the driver so I can update the driver on device manager but I can't find it anywhere or how to fix my particular problem. Hope you guys can tell me how to go out from this hole I'm sinking.
