Kindle Fire HD 8.9 model has been released and now you can use the root instructions listed in this post to gain access to all of its system’s functions.
The root has been bundled by ‘mdblaze’ from XDA and the tool used to apply the changes is named Bin4ry Tool. It is an exploit for Sony tablets and it seems like it works with your Kindle Fire HD 8.9inch model too. This guide should be very easy to apply.
To be sure that this root tool will work with your computer you should install its USB Drivers. Download the drivers from HERE. Extract the contents and after that run the Exe file to install the USB drivers for Kindle Fire HD on your PC.
Apply this root only on the Kindle Fire HD 8.9 inch variant. Do not try to flash these root files on any other Android tablet or smartphone. Create backups of all the files you have currently stored on your tablet device so that in case something goes wrong and you cannot use them after the root, then you will be able to restore them from your PC or whatever media you’ve used to keep the files safe.
Now that you know all this general info, I think that you should move to the how-to guide. Also, remember to disable all antivirus applications. Rooting your tablet might void its warranty, but you shouldn’t worry as you can easily unroot it using the ‘NOTE’ listed at the end of the tutorial.
Make sure that you apply all the changes that I’ve listed because otherwise you cannot complete the root. If you have any problems with the tutorial and you cannot apply all actions, then you should leave a detailed comment at the end of this post and we will try to come with a solution to your problems.
Extract the contents of this zip and place in a folder that is saved on your desktop PC screen.
Open Settings on your Kindle Fire HD device and enable the ADB from the Security section.
Use the USB cable to connect your tablet to your PC. The rest of the drivers will now install on your PC and when it is done you can continue to the next step.
Open the folder created at step 2, the one that contains the root files. Launch the ‘RunMe’ file, which is the root utility.
A new window will load and you need to press the ’2′ button on your keyboard. Press Enter key and then select ‘Special’.
Next, press ’1′ and then ‘Enter’ to choose ROOT. Follow the onscreen instructions to finish the root.
That’s it, you’ve successfully rooted your device.
NOTE: If you ever decide to un-root your Kindle Fire HD 8.9″, launch the Bin4ry Root Tool and press ‘x’ button and then ENTER. Select ‘unroot’ and then follow the on-screen instructions to unroot your device. This process will not take more than 10 seconds.
These were all the steps that you had to take. If you have any extra questions, post them at the end of this post.
