How to root Sony Xperia Z Ultra C6833, C6806, C6802 Android 4.4.4 Kitkat

So this week, I just received my Sony Xperia Z Ultra and with a 1080p 6.4 inch display aura of this fabulous monster, I couldn’t wait to get my customization wizard upon this device. I recently lost my GS4 to the cynical streets of Nairobi which I have been using for quite a while, so spare me if I sound too zealous here.
I have used a few Xperia devices before, but that was a while back and those were still running on older firmware with different root methods. Sony have quite a reputation when it comes to extending firmware support to older devices so that users can get to enjoy the latest and greatest versions of android, which in retrospect contributed to my shift to the Japanese handset maker. Am loving my Z Ultra so far and even received an OTA update notification for Android 5.0.2 Lollipop but I will save that for later. Apart from the average camera without the benefit of an LED Flash and unusually large vertical bezels that further exaggerate it’s size, I have little to complain about this device. Nothing could have prepared me for such a big leap from a long term relationship with familiar Samsung, but believe me this gigantic droid is almost making me forget my Samsung touch whiz user experience, really fast! Snappy fast UI, possibly the best gaming experience on any high end android device right now, improved battery life, fluid web browsing experience and the bottom highlight 6.4 inch triluminous display kicker makes the whole experience very different.
I still love noodling around with a Samsung device but looking for something different, I couldn’t have anticipated a better replacement to my Galaxy S4 (I still miss that camera though!)
I received the c6833 LTE model running on recent 4.4.4 Kitkat 14.4.A.0.108 Firmware. This firmware comes with a locked bootloader, but luckily for ZU owners on this firmware, there is a work around to root your device without necessarily unlocking the bootloader.
So I figured out why not share this root method since it’s almost stupidly simple and works great in rooting quite a number of other Xperia devices as well? This root method is almost a one click root, the simplest among many other root methods I have used for Xperia devices.


  • Make sure your device has above 60% battery charge
  • Back up all important personal data and apps and settings
  • This root guide applies to Sony Xperia Z Ultra variants ONLY. Trying it on other unconfirmed android phone models may leave your device hard bricked.
  • The decision to root your device is entirely on you, Self Tech Genius will not be held liable for any possible damage to the device.
  • Rooting and flashing custom ROMS on your Sony Xperia device automatically voids its warranty.

If you get any errors during the process and the above process fails, you might need to reinstall the USB drivers as well as ADB Drivers and try plugging the device to a different USB port to ensure a proper communication is established between the PC and your  android device.  Restart the process again making sure that you follow every instruction carefully.
