Yep, somebody already rooted the Kindle Fire HD

Man, the hacking community just doesn't let up. Though it's been less than two weeks since the Kindle Fire HD entered the market, the device has already been successfully rooted, something that may come as a surprise as many were only recently expressing concerns about how Amazon's newest Kindles were being shipped with locked bootloaders.
While not directly responsible for the exploit, sparkym3 from the XDA-Developers forum discovered a bug in Android Ice Cream Sandwich on the Transformer Prime that led to this breakthrough. If you're wondering why anyone would want to root their Kindle Fire HD, it's pretty simple: Rooting grants you full access to the device's file system. In other words, you'll be able to do just about anything you want with the Kindle Fire HD. You could install a new operating system if that's what floats your boat.
However, here's a word of warning if you're new to the concept. While rooting can certainly open up new doors and possibly even transform your device into a better machine, failure can turn your freshly-bought Kindle Fire HD into a useless paperweight. More importantly, because rooting voids warranties, you won't be able to get a replacement from Amazon. It's all or nothing.
Of course, if you're the sort who just has to have things your own way, rooting is definitely worth the possible risks. Previously, we saw a Kindle Fire get rooted to accommodate Android 4.1 Jelly Bean, so I can only imagine what heights the new Kindle Fire HD is capable of aspiring to.
Everything else aside, if you're brave enough to take the plunge, you can find full instructions on Droid Dog. We take no responsibility for what may befall your new Kindle. Good luck.
