TMOBILE USA takes forever to launch new software updates. I wanted Android Kitkat 4.4.4 on my XPERIA Z C6606 Now!
After hours of researching and looking a threads, I managed to get KitKat 4.4.2 on my phone followed by Kitkat 4.4.4 and ROOTED! :victory:
Here is my guide to save you all time. I will not be responsible if you brick your phone. If you brick your phone use Sony's PC companion to repair your phone.
This Guide was tested and worked on my XPERIA Z1 C6606 Tmobile Locked Bootloader. On Windows 7 PC.
Have [[NOT]] tested on other XPERIA devices and would not recommend it on other devices.
[[BACK UP ALL DATA to your PC]] All data on your phone and SD card will be wiped!

c. connect the phone access sd card and create a new folder called "apps".
d. Put tr.apk in the apps folder you just newly created on your sd card.

I would recommend downloading SuperSu from the Playstore and granting permissions to it.
Credits go to:
Androxyde for Flashtool
Chainfire for SuperSU
Geohot for the original towelroot exploit
NUT for kitkat 4.4.2 US customized .ftf flash file.
Lastly, I should get some credit for compiling this guide. :angel:
extra references.
