Amazon's Kindle Fire HD tablets are very affordable, and the hardware is pretty compelling. It's just a crying shame that the Fire OS powering the device doesn't quite have the feature set that we enthusiast have come to expect. But that's nothing a little ROM action can't address, and CyanogenMod has just the solution - nightlies for the 2012 Kindle Fire HD 7" and 8.9."
The builds currently available show up as experimental because they were produced on demand, but regular nightlies are due out starting today. These are running CyanogenMod 11, which comes with a relatively clean version of KitKat.
As always, exercise caution when working with these files. This wouldn't be the best surprise to leave for Grandma to find when she returns to pick up her Kindle Fire HD. Sometimes these things are stable, and sometimes they aren't. Links to see for yourself are available below.
