DANGER WILL ROBINSON I've tried with two different ducks flashing them to this firmware (and also changed sd card format) and after trying to flash to the twin duck for file exfiltration, BOTH ducks died. Tried flashing to standard after and only got solid red light. Got the solid red light on Twin FW too. So DANGER when flashing to twin duck! Thankfully the customer service there rocks and they're sending me two brand new ones. I'm gonna send these back to them so they can do some testing on them. I literally tried everything I could think of doing. Flashing, reflashing, flashing manually, flashing with ducky-flasher, reinstalling the proper Atmel processor driver manually the proper way and no fixing it. Dead ducks. But again thank to the awesome customer service with Hak5 they're replacing them. GO HAK5! :)
