Root An Xperia Z/ZL

The latest update that Sony has rolled out for the Xperia Z and ZL/ZQ is to Android 4.4.2 KitKat based on build number 10.5.A.0.230.  If you’ve updated your device, you’ve probably noticed that you’ve lost root access.

There are several ways to root an Xperia device, but a lot of them require you to unlock your bootloader which causes you to lose your warranty.  If you want to root your Xperia Z or ZL/ZQ but don’t want to unlock your bootloader, we have a solution for you.

Developer Geohot has come up with the Towelroot app that can root a number of Android devices.  Towelroot requires you to install a small apk file that can root your device in one tap, without unlocking your bootloader.

In this guide, we’re going to show you how you can root a Sony Xperia Z/ZL (all variants) that runs on Android 4.4.2 KitKat 10.5.A.0.230 without unlocking the bootloader by using Towelroot.

Prepare your phone:

  1. This guide is for use with the Sony Xperia Z C6602, C6603, C6616 and Sony Xperia ZL C6502, C6503, C650 running on the latest Android 4.4.2 KitKat firmware based on the build number 10.5.A.0.230.
  2. Have your battery charged to at least over 60 percent.
  3. Enable USB debugging mode by one of these two methods:
    • Settings>Developer options>USB debugging.
    • Settings>About device>Build number. Tap Build Number 7 times.
  4. Have an OEM data cable that you can use to connect the phone to a PC.
  5. Allow “Unknown Sources”. To do so, got to your phones settings, Security>Unknown Sources

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device.  Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers.  Be responsible and keep these in mind before you decide to proceed on your own responsibility.  In case a mishap occurs we or the device manufacturers should never be held responsible.
