The easy way for me to do it with the Kindle Fire Utility 0.9.9. This was the only zip I used. Once you unzip it, it has everything you need in the folder. Try going to Youtube and searching for video by reverendkjr. He goes through all the steps.And this is safe for system version 6.3.2 of the Kindle Fire?
I don't have the HD tablet and as far as I know, the tablet I have now was the first Kindle Fire given to the public... I just want to make sure I won't be destroying my device with your steps, since I'm not very "tech savvy".
