Kindle Fire 6.2.1 update: improve performance, breaks root

Amazon releases Kindle Fire 6.2.1 update, breaks root, disables SuperOneClick utility. This is the second update of Kindle Fire. Similar with the 6.2 update, Kindle Fire 6.2.1 is designed to update automatically when a tablet is connected to a WiFi network.

Added Constraints

There are users complaint about one click purchase functions is too “convenient” and make their kids easy to get their wanted goods. The new Kindle Fire 6.2.1 provide a WiFi lock function for parents to turn off internet access for their kids.

The Kindle Fire 6.2.1 update are reported to removes root privileges on tablets that have been rooted.  And users can not re-boot the device using the SuperOneClick utility.

But the root access is not necessary for Kindle Fire as users can install most App Market and third party apps. But if you prefer Google service and Android Market, you can use the  Kindle Fire Utility stop amazon auto-update. ( learn how to prevent Kindle Fire 6.2.1 software update )

Improved scrolling experience

The scrolling experience of Kindle Fire is very poor. But the Nook Tablet do much better. Amazon announced they would fix this bug by software update. Users who got the new Kindle Fire 6.2.1 update also confirm the improvement. But I don’t if the problem is complete fixed.

Custom default wallpaper

Users are allowed to custom their main interface like Apple CoverFlow.  You can remove e-books, apps and musics on the default screen. It should be a good experience as I don’t want to show too much items on the screen. THHGZNHE5TR6
