Hi!!
Just got your Xperia Z Ultra and start looking on how to root, unlock your bootloader and do everything you can for start playing with your phone with a maximum of security? You are at the good place!!

First of all, install PC Companion, you just need to plug your phone on the PC and follow instructions on your phone and PC.

To make things clear, I didn't do any of those tools and link the threads where they come from, so if you want to thanks devs do it there. I tried all of them without any problem and I do this thread for help people who know nothing about Sony Android devices or simply want to find everything in one place. They are fully working, so if things go wrong while following explanations this is bad luck, you did something wrong and/or forgot to do something. Neither I nor the Devs can be kept responsible for what you are doing on your device.

Root and TA Backup

Mod edit - VRoot links and install guide removed
until such time as the validity of this software can be determined due to some security concerns regarding this application.

Youtube tutorial made by hamdogg

Thanks a lot hamdogg

First tool you need to know when you own a Sony Android device is Flashtool. I invite every owner wishing to root, unlock or mess with your phone to install this program and install Flashtoo-drivers.exe (directory: C:\Flashtool\Drivers\). This tool is a jewel, you can flash any factory firmware, unlock your bootloader and cherry on the cake, make a TA backup, that will backup all your TA partitions including locked bootloader with DRM keys. Keys those are necessary to enable X-Reality and bravia engine.

But to be able to do a TA backup you need first to root your Z Ultra.

- First of all you need to enable USB debugging, you will find it on /Settings/Developer options. For enable Developer options you need to go on /Settings/About phone/ and tap 8 times on Build number.



Mod edit - VRoot links and install guide removed
until such time as the validity of this software can be determined due to some security concerns regarding this application.



- OK, now SuperSu closed by itself and disappeared, no stress it's normal, just restart your phone.

- After full reboot, open supersu again, and it won't ask you for update binary anymore. Just close it.

- Download Titanium Backup Root and open it.



- Just be patient, promt for root access can take time, but it'll come.



Enjoy!!

I just updated from .526 to .532 and done this process and it was successful at the first try. If it doesn't work just try again. It work on any firmware version and country

All is thanks to @nickylou88 for this process.


And if you need more support you can look at this thread you have all information you need inside. The OP introduce another program, but VRoot is the less complicate to use and work as well.

Now you can make a TA backup following the instructions on this post.

Ok, now your phone is rooted, but more important you made a backup of your TA partition. It is important because if you soft brick your phone or wish to restore your bootloader to locked state if you unlocked it now you can.

I am not doing a TA backup tuto as the one on the original thread is more than complet

Here there is the other program that allow you to make a TA backup.
hamdogg provide us a really good Youtube tuto.

When done boot your device you are unlocked.

Now it is time to flash Recovery. For do so you need to have adb and fastboot on your PC, all the information you need for install it and more can be find Here.

Another Youtube tuto from hamdogg

To flash recovery you need to put advanced stock kernel v5.img to “C:\SDK ANdroid\sdk\platform-tools\” then type :

Code:
fastboot flash boot C:\SDK ANdroid\sdk\platform-tools\advanced stock kernel v5.img
Reboot your phone to system a first time then turn it off.

To enter CMW:

[B] Flash or update a firmware from another country [/B]
While looking on the forum it is possible for you to find someone posting the latest firmware, but when you plug your phone on your PC and look for update with PC Companion it tell you have the latest firmware. It simply because the firmware came out first on another country, you can simply wait for it to come in your country. If you don't want to wait you have 2 possibilities.

- Download the .ftf and flash it via Flashtool

Follow step by step this post

- Modify your CDA code on your build.prop but need to be rooted

Open build.prop with any explorer with root permission (I use root explorer) and modify the following values with the values you need:



Reboot your phone then plug it to your PC and update with PC Companion.

List of CDA

Excellent, thanks.

Edit: It seems Flashtool 0.9.11 doesn't support the XUltra out of the box for TA Backup. Trying to add the device defn file, but no success yet.

Ok done-> go here and get http://forum.xda-developers.com/show....php?t=2428319 C680X.ftd file, rename to C680X.gz and uncompress. On a mac, go to flashtool application and show package contents. Copy C680X folder to devices folder.

Flashtool will then find the Ultra
