Amazon has made available new firmware packages targeted at its 4th-Gen Fire HD 6, HD 7, and HDX 8.9 tablets, namely build 5.4.2, which gives owners the ability to download Audiobooks to their SD memory card.



In addition to that, users who have multiple profiles on their device, the audiobooks downloaded to the microSD card will only be available to the profile that downloaded it. Moreover, this update also includes general improvements and performance enhancements.
If you intend to upgrade your device, first save the downloadable package on your desktop, connect the tablet to the computer using a USB cable, and transfer the .bin file onto the root folder of your Kindle’s internal storage.
However, be aware that dropping the firmware file into any other folder might prevent the installation process from being initiated. Thus, pay special attention to this step and also monitor the transfer so that it finishes completely before disconnecting the Kindle.
Afterwards, go to Settings > Device Options > System Updates, and tap “Update” to start the upgrade process. At this point, the tablet will restart and then show an “Installing system update” message, so make sure you don’t interrupt it in any way.
With this in mind, from the links below, download the appropriate file suitable for your device model, carefully apply the new firmware, and enjoy your improved Kindle tablet. Also, constantly check our website to stay “updated one minute ago.”
