Today, while doing my daily reading blogs, I found an article by El Android Libre (in spanish) of an app for rooting Android devices quickly, so I decided to try it on my own and effectively, the application success to root my Fire HD 6!. His name is KingRoot. I'm very excited, it worked, and so far I have not noticed errors in the operation of my tablet (at least, today). I could say that this is the ultimate solution to root the Fire HD 6.
WARNING: This is a Chinese application, so I can not guarantee that it 100% safe to use . IF YOU INSTALL THIS, IT IS AT YOUR OWN RISK. I AM NOT RESPONSIBLE FOR BUGS, BOOTLOOPS OR SOFTBRICKS..
If the antivirus software on your tablet shows this application as a virus, it is evident: for root you device, this app made a series of exploits to the operating system, and obviously the antivirus will display warnings before or during the process
I hope this can be useful to someone.

This process is not yet totally safe and we have very little information. Indeed, it is possible to root the Fire HD 6/7, but there's a very high risk of the device is unable to boot.
- Open the KingUser app
- Press the Settings button (upper right corner)
- Then press the "Remove Permission Root" option
- Confirm and wait a few minutes.
