How to Root the Sony Xperia Z3

Got a shiny new Sony Xperia Z3 and wish to root it to enjoy it at its fullest? No worries, here’s how you can do that. Rooting the Xperia Z3 isn’t a daunting task, and you should be able to root your device within a couple of minutes. Once rooted, you’ll be able to go beyond what your device can offer now. Here’s how:

Rooting is the process of gaining administrative rights on your Android device.  Once we root our Android device, we can then make changes to it to customize it well beyond what it normally can do.

Once you have root access on your Sony Xperia Z3, you’ll be able to:

  • Remove apps that were preinstalled by your carrier/manufacturer from your device.
  • Free up storage space (because of the above benefit).
  • Increase battery life (apps that might have been running constantly can be removed).
  • Increase performance (after removing apps that are always running, the device will be less bogged down and run smoother).
  • Update to a new version of Android (by flashing a custom recovery/ROM, see the end of this procedure for more info on that).
  • Tons of other customizations when you use your new found administrative rights to flash a custom ROM (again, see the end of this procedure for more info on that).

  1. Hello, this is my first time trying to root a phone so excuse my noobness :p Anyway I am unable to get past lll. 5, when i type in adb reboot fastboot I just get “device offline”. I have done some research on this but cannot find a solution. And so I have come here, please help 🙂

    1. Hello,

      Try issuing the following command – adb devices

      If it lists your device, it means your device’s been recognized by your PC and you can go ahead and do the procedure. But it if doesn’t show your device in the list, then you don’t have the required drivers installed on your PC.

      Head to your manufacturer’s website, download and install the latest drivers on your PC, and you’ll be all set.

      Hope this helps!

      1. Hello thanks for the answer, much appreciated! However I am still unsuccessful. I will try to explain my problem a bit more detailed: I have the files from the fastboot folder on my desktop as well as the advanced kernel img file. When I open a command window and type in “adb reboot fastboot” I just get “error: device offline” I tried your other solution and typed “adb devices”, my phone is recognized but it says it’s offline. To clarify this is step lll. 5. It seems and can’t really go ahead with the procedure although it is recognized.

          1. Thanks again for a quick answer! Still doesn’t work unfortunately. It says:

            “adb server is out of date. killing…
            *daemon started successfully*
            error: device offline”

          2. If the above solutions didn’t work for you, you might want to go the hard way.

            Turn OFF your device, pull the battery out and then put it back in after a couple of seconds, hold down Volume UP and Power buttons together. You should get into bootloader mode from where you can select Fastboot.

            Hope this helps you!

  2. Can someone please help me I flashed the bootrom but now my phone won’t start if I press volume up and the powerbutton. If I just use the powerbutton there is no problem and it just starts, but it won’t even turn on using volume up button with the powerbutton. Thanks for your help allready
