Amazon announced a critical software update for Kindle owners. Anyone using a Kindle Pre-2012 should be weary to update over wi-fi before March 22, 2016. As the new update will essentially brick your device until you manually update it via a computer.
Important: If you do not update your device by March 22, 2016, you will receive the following message on your device: Your Kindle is unable to connect at this time. Please make sure you are within wireless range and try again. If the problem persists, please restart your Kindle from the Menu in Settings and try again. If you see this message on your device on or after March 22, you will need to manually install the latest software update for your device. Go to Fire & Kindle Software Updates for more details.
Luckily they offer a simple chart to make it easier to ensure your device may need updating.
So as a friendly reminder from Amazon & I to you, update your Kindles! Read on.
