[Q] How To Root Kindle Fire 3rd Gen Running FireOS 4.5.5

Hi all,

I've been looking to root my kindle fire for a while now. I have been sideloading apps for several months now, but some of the apps I would really like are incompatible with my tablet.

I am running FireOS 4.5.5 on my 3rd Generation Kindle Fire HD. Note that this is a now relatively old tablet, as I believe it was released in 2013.

I have read and understand threads on how to root Kindle Fire 4th Gen running 4.5.5 and Kindle Fire 3rd Gen running 4.5.2, but I cannot find a suitable guide for my in between tablet. I don't feel comfortable winging it, since I am completely unfamiliar with Amazon's custom version of Android.

Unfortunately, the easy root path of upgrading to 5.0.n and then rolling back to 4.5.3 is unavailable to me, as the developer's version is not made available to 3rd generation tablets.

With this information, can anyone tell me how to root my tablet? I don't necessarily need a "noob step-by-step" guide, but at least a general outline would be appreciated.

Also, this is my first post; hopefully I'm following all the rules and regulations!

Thanks!
