Xperia Z and ZL/ZQ are running on Android 4.4.2 KitKat that Sony rolled out recently based on the build number 10.5.A.0.230.  If you’ve updated to this latest firmware, and you’ve lost the root rights on your device or just in case you’re looking to root your device for the first on this latest firmware, you may find a number of methods to do so, but most probably most of them will require you to unlock the bootloader of your Sony Xperia device, but many of you might not get the root access on their device just because you don’t want to unlock the bootloader and loose the warranty and finish the official touch on the device.

Famous developer, Geohot has recently come up with Towelroot exploit that roots a number of Android devices without any hiccups here and there. The tools is a small apk file that can be installed and roots the device in just one tap, there isn’t any bootloader unlock required. A number of Xperia devices running on the kernel before 3rd of June, 2014 can be rooted using this exploit.

What to do once you’re rooted?

Rooting your phone gives you complete access over all the data which is apparently locked by the manufacturers. This includes removal of the factory restrictions and making changes to the internal system and the operating system. Gaining the root access gives you the privileges to install various applications to enhance the performance of your device, allows you to remove the built-in applications/programs, helps you to upgrade the battery life of your device & install the apps which require the root access for the proper functionality and modify your device in so many other ways e.g using mods and flashing custom recoveries and custom ROMs. Here’s our collection of 10 Best Root Apps.

That’s all. Please consider a donation to the developer for his hardwork on this application. Just in case you got any queries or you face any difficulties regarding this post, feel free to reach us through the comment box below. We will try our best to help you out.

      @garduniverse:disqus no, I guess you will have to flash stock firmware, simply uninstalling the app won’t unroot it.
