Conclusion

Thanks to everyone mentioned at http://forum.xda-developers.com/kindle-fire-hdx/orig-development/dev-bootloader-unlock-procedure-software-t3030281. I'm no quite sure who is responsible for what. I wrote most of this code months ago, before Cuber was released, but thanks to dpeddi and whoever else for figuring out the mmc ID stuff, I have decided to publish it.
