When I flash my rubber ducky to Twin Duck it stopped working. I had to flash it back to the original firmware to get it working again. If there is a solid red light it means that your rubber ducky isn't "talking" to your computer.
I flash my rubber ducky with the firmware twin duck. The usb now doesn't inject the code. The light flashes green and red. Is there a way to fix it? By the way im was using mint to flash the ducky.
