These are flashable zip file and FTF pairs for the latest KitKat firmware 14.3.A.0.681 for C6833/C6806/C6802 based on [NUT]'s modifications. I couldn't wait for his firmware so decided to make it .
The upgrade instructions are exactly the same as in this thread: http://xdaforums.com/showthread.php?t=2631768 . You only need to use the flashable zip and FTF files in this thread instead. In a nutshell:
These instructions are relatively safe and you can always downgrade using the other flashable zip/FTF if you so wish.
Lots of credits go to NUT & co. for making the original flashable zip!.
Notes:
- Some people run into a bug that makes camera non-functional. If you have this bug you can try flashing zip/stripped FTF from another region (e.g., US) instead.
- If you have issues remounting /system in TWRP you can try @[NUT]'s patch for the recovery here: http://xdaforums.com/showpost.php?p=51378028&postcount=88 . It can be flashed after you flash the flashable zip with adb sideload recoverypatch.zip inside the package on Linux or running install.bat on Windows.

The upgrade instructions are exactly the same as in this thread: http://xdaforums.com/showthread.php?t=2631768 . You only need to use the flashable zip and FTF files in this thread instead. In a nutshell:
- Install recovery (either via a root exploit or unlocking the bootloader). Note: unlocking the bootloader will typically result in data loss, you are advised to use the root exploit on the older firmware instead of touching the bootloader.
- Enter recovery and flash Sony Xperia Z Ultra Europe LTE_14.3.A.0.681_flashable.zip
- Power off the device and enter flash mode
- Flash Sony Xperia Z Ultra Europe LTE_14.3.A.0.681_Stripped.ftf using FlashTool (0.9.15.0 or later, older versions won't work)
These instructions are relatively safe and you can always downgrade using the other flashable zip/FTF if you so wish.
