So you are probably looking for rooting the 7 inch version. I'll give you the instructions here. First off, you WILL void your warranty. I have personally rooted and installed a lightly modified stock version of Android called Cyanogenmod on my own and their is a slight possibility for error to occur. Nonetheless, given how slow and laggy Amazon's Fire OS is and how google's app store is restricted, I personally think the risk is acceptable. Second off, since I don't want to be the guy that destroy's your Kindle; I will need to know what software version you are updated to on the Kindle Fire. You can find this information by going to settings and then checking what the software version is. We can go from their.
