Although the Kindle Fire HD from a couple years ago is already an older device, that doesn't mean we can't breath some new life into it. In fact, if you're an owner of a Kindle Fire HD and are looking for a way to bring the tablet back from the dead, it looks as though we might have a way for you to accomplish just that. Among other things, the Kindle Fire HD has plenty of potential to be great. The issue is that it can't access the wonderful nature of things that Android has to offer in its true form simply because it doesn't run a regular version of Android. Although it is an Android tablet, it's Amazon's own re-worked version and for some of us there's just no replacement for something as awesome as Android the way it was meant to be. The good news for you if you feel the same way is that the Cyanogenmod community has take it upon themselves to get a version of the aftermarket Android firmware running and ready for the Kindle Fire HD, so the awesome hardware can take advantage of truly awesome software.
Before we delve any further into this a couple things should be noted, this is slated for compatibility with both the 7-inch and 8.9-inch models of the tablet, so no worries there, but the software is more or less in a beta or alpha testing stage at the moment. Meaning it's experimental, which could and most likely does mean bugs. Now onto the fun stuff. First off, this is a version of Cyanogenmod 11, so yes, you would in affect be bringing your Kindle Fire HD forward into the modern age of Android software builds. If you have messed with Cyanogenmod 11 at all before on any other devices, then you already know how awesome of a ROM it is, and will most likely be plenty happy to get it installed on your device.
As expected, your Kindle Fire HD will have to be rooted of course to do anything with this software, and if it isn't already done we would suggest flipping over to a place like XDA to look up some processes on how to correctly root your Kindle Fire HD, they shouldn't be too hard. Once that's all said and done come back to these links(Kindle Fire HD 7-inch, Kindle Fire HD 8.9-inch) and grab your downloads, then proceed. Make sure you have at least 200 MB of space left for you to work with, and you should be good to go.
