It would appear I cant run this in windows due to missing module serial.

Now here's the strangest thing:

I mentioned earlier about a brief white amazon logo that faded out after a second, never been able to reproduce it.. until just before I did what's pasted above. The thing is, I still have to use fireiso just to kick the firestick into fastboot mode, but with extra power added so I can reboot laptop without losing fastboot mode on firestick, I took the boot.img from the origional 7.1, flashed it in windows, then flashed the upade as posted. I got a brief glimpse of the white amazon logo, which lasted all of 1. sumat seconds, before black screen kicked in again.

Now what ese can I flash?

I think we need an updated kamakiri and updated fireiso, they are no longer of use by my experience.
