Amazon has released a minor software update for the Amazon Kindle Fire $199 tablet. The only noticeable difference is that there’s now a button that lets you enable full screen browsing in the Silk web browser. It also includes email improvements.
Like earlier updates, Kindle Fire software version 6.2.2 will also remove root access. Fortunately hacker Justin Case has already updated his BurritoRoot utility so that you can easily re-root the Kindle Fire even after downloading the latest software.
Just download BurritoRoot 2 and follow the instructions at the xda-developers forum. You may have to run Kindle Fire Utility again if you want to re-install the Android Market, TWRP 2.0, or any other software that this update kills.
Amazon is pushing out 6.2.2 as an over-the-air update, which means most Kindle Fire devices will download and install the update automatically when connected to a WiFi network. But if you’re impatient you can download the latest firmware manually from Amazon’s servers.
If you’re running a custom ROM such as CyanogenMod or MIUI your device won’t receive the over-the-air update.
