USB rubber ducky flashing red/green after twin duck flash

[Thrasherop]

I just used this tutorial 

 to flash my ducky with the twin duck firmware. However, immediately after the flash it began blinking red/green and "installing device driver" popped up. It continued to blink even after the driver was finished installing. I tried unplugging and replugging in the ducky. I also tried re-running the flash command. I am now getting the error "FAIL could not open USB device". Help?

Update: The "could not open USB device" was because I didn't plug it in while pressing the button. However, it is still blinking red and green and is not showing up as an available disk

After flashing my rubber ducky with twin, it refused to boot( led flashing LED)

micro SD was connected at time of flashing...

any idea what my mistake was?

btw I used Ubuntu for flashing...

I never figured mine out. I ended up flashing it back to normal.
