In a familiar turn of events, Amazon has pushed out another root-breaking firmware update, bringing the Kindle Fire's firmware up to version 6.2.2.

Shortly after Amazon's last Kindle Fire update, our very own Justin Case made quick work of gaining root access for the Kindle Fire once again, releasing BurritoRoot, a tool that made rooting the Fire quick and (relatively) easy. Unfortunately, Amazon's latest update keeps BurritoRoot from doing its job, but it appears to bring about at least one useful change.

The only visible improvement is a full screen toggle button added to Amazon's Silk browser. Amazon's support documentation doesn't include information regarding 6.2.2 just yet, but when it does we'll be here to update with a full list of changes.

Update: Here's the changelog:

This update

  • enhances fluidity and performance
  • improves support for manually set up e-mail providers in the Email app
  • and offers a new full screen mode for viewing web pages

If you'd like to manually grab the update, it can be downloaded here, courtesy of XDA user b63. Just download the file, place it in your Fire's kindleupdates folder, and go to Settings > Device > Update your Kindle. Easy as that.

For now, there is no root solution available for the new update, but you can be sure we'll be here to cover any fixes as they emerge.
