Kali Linux on Kinde Fire HD 6

First of all I am doing this with 16 GB internal SD storage.

Second, be root user.

Third, download the Linux Installer and follow instructions.

Finally, make sure you can connect the Kindle Fire to your PC as you may find it easier to navigate to the after market sites for the necessary APKs, e.g. Zip extractor or Root Browser, and then copy the APK to your Kindle Fire and install them.

Buena suerte amigos y amigas
