Root Xperia ZL Running on Android 4.2.2 Jelly Bean [GUIDE]

Prior to the Android 4.2.2 roll-out for the Xperia Z, Sony released the Jelly Bean update for the Xperia ZL, which was shipped with Android version, 4.1.2.

With build version 10.3.A.0.423, the Android 4.2.2 official update is also available for the European LTE version of the handsets bearing model number C6503.

Those who have already upgraded their handsets with Android 4.2.2 and currently looking for a root method, may follow our step-by-step guide. The tutorial uses Easy Rooting Toolkit v16 released by recognised XDA developer, DooMLoRD.

The key feature of the toolkit is it worked on both locked and unlocked bootloaders. Along with rooting the device, the toolkit installs Busybox and SU files.

IBTimes UK reminds its readers that it will not be held liable for damage to the device. Users are also advised to verify that their devices meet following requirements.

Pre-requisites

1) Install USB Driver for Sony Xperia ZL to transfer files between the Android device and the computer.

2) Enable USB Debugging Mode on the phone to connect it with the computer and use Android SDK with it. [Press Menu>> Settings>> Applications. From there navigate and click on Development option and check the USB Debugging Mode.]

3) As the tutorial might wipe all data of the phone, create a back-up. If the device is having any custom recoveries such as ClockworkMod/TWRP already installed, then backup data using the recovery. Click here for guide to install CWM recovery on Xperia ZL.

4) The battery of Xperia ZL should have above 80 per cent of charge.

5) Increase the screen timeout on the phone to 10 minutes by navigating to Setting>> Display>> Sleep>> 10 mins.

6) Enable install from Unknown Sources by selecting Menu>>Settings>> Applications.

7) Rooting the device will void manufacturer's warranty. However, users can reclaim the warranty back by unrooting the device later.
