Note: I think you have to be below 10.5 software version? (Unsure)
Your first step is to get adb and fastboot drivers working.
Then download minimal adb and fastboot (Google it)
You can test adb by typing:
from the command prompt you get when you run with minimal adb
You can now boot into fastboot
Adb shell su -c "reboot bootloader"
Now test fastboot by typing
Fastboot -i 0x1949 devices
If all works
Then find all the files
Hashcode mentions at the first page of this thread (I think they were around post 545)
Run the commands one by one
If you don't use the latest twrp you will not be able to install cm11 but can cm10
Note: you have to immediately flash a ROM. Twrp goes away every time you boot kindle os..
