Braiins, Awesomeminer doesn't support this unit yet and I tried to search on Google there is Vnish firmware that supports this unit but I do not know if the site that I found on Google is legit or not because the vnish firmware I know safe is from asic.to.

If your purpose is the low-power mode then you don't need to flash it with different firmware because there is a way to get this hidden feature on this unit try the method by mikeywith below
