In case you’ve already updated and you’re a looking for a method to root your device on the latest Android 4.4.2 KitKat 14.3.A.0.681 firmware, then you’re spotted the right spot at the moment.

Before we head towards the pre-requisites and root instructions, some of you, whoa are newbies, may want to know what is root access and why you should root your device. To make it clear, we’ll be first having a look on a brief introduction of the root access.

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 custom roms. By installing custom recovery, you can flash custom roms in the phone easily. Custom recovery also let’s you backup your current rom and restore it in case of any mishap. There is a laundry list of things you can do after having your device rooted and installed the custom recovery, now once you’re rooted and have installed custom recovery, go ahead and enjoy it on your phone. Here’s our collection of 10 Best Root Apps.

    2. Please make sure that your phone’s battery is charged at least over 60%. This is highly recommended in order to prevent any power issues during the recovery flashing process.

    Great job Bro. It really works on my Z1.

    Greetings from Ecuador

    • superman

      Did u unlock bootloader first ?

      • Usama Mujtaba

        @disqus_pWr4QurUMz:disqus for this method, you need to unlock it first.

  • David

    With this process the data is erased from my phone? Could I lose the warranty?

    • Usama Mujtaba

      @disqus_9uxSatOZtF:disqus unlocking bootloader will erase + lose your warranty as well.

      • Daniel Hyuga

        so i need to unlock the bootloader to root then?

        • Usama Mujtaba

          @danielhyuga:disqus or this method, yes you need to unlock first and then root.

  • Usama Mujtaba

    @disqus_8ma2v2QA0G:disqus
    why would you flash C69XX stripped after this? We just need to root the device, so it just requires SuperSu.zip!

    • Ah Peh

      The problem is that I was unable to boot-up my phone after flashing the ‘SuperSu.Zip’ file. I manage to do so after flashing the ‘C69XX stripped’ file. However, I’m suspecting incompatible ‘boot.img’ was being used in the CWM process. Just sharing my experience.

      • Usama Mujtaba

        @ahpeh:disqus in our guide the CWM is proper and works for the device and no Striped firmware is needed. However you may have done something wrong that caused this, stripped firmware has just brought the latest kernel in your device. This solution may help other people if they face the same issue. Thanks

  • Alfred Broman

    Hey, It seems like I need CWM 6 Recovery on my device and that unlocks the bootloader. Witch means my camera itn’t going to work after this:/ Is that true?

    • Usama Mujtaba

      @alfredbroman:disqus no. If you unlock the bootloader after updating to Android 4.3, camera will work. Sony has fixed this bug long ago.

  • Usama Mujtaba

    @anitachvez:disqus update it manually and then root it. You might face some problems updating it via OTA if you already have rooted your current firmware.

    • Anita Chávez

      Thanks for the information, I have the new android but a try to root but I cant. Well apparently installed the superuser by entering the phone but not rooteado.

      • Usama Mujtaba

        @anitachvez:disqus what problem are you facing exactly? How did you install supersu?

        • Anita Chávez

          Now install the root as shown in the guide, but start the phone and not root.

  • Florian Zöller

    hello, can i change the language after installing back to german?

    • Usama Mujtaba

      @florianzller:disqus yes you can select the language you want.
