[Xperia Z General] Spock0785:
I have installed 10.5.1.A.0.283 on my XPeria Z.

But i could not Root it, even the Towel Root does not work on this device with this Software. So maybe someday this How to is no longer needed. :-/

So i tried to make my own Root Method and it worked.

I tried it with an clean Installation and it worked nice. So if you want to keep your Data and so on, so select the appropriate Options in the Flashtool.

What do i need?

1. Unlocked Bootloader... Google it, there you should be enough, how to unlock it (the easist way is over the Flashtool if you already got your code)

2. the Flashtool http://www.flashtool.net/index.php

3. an Firmware File. (Since the Flashtool (latest Version) can Download the latest Software by its Self, you do NOT need such an File)

4. the Superuser ZIP --> https://play.google.com/store/apps/details?id=com.koushikdutta.superuser

Direct Link http://download.clockworkmod.com/superuser/superuser.zip.

5. The Doomlord Kernel --> http://xdaforums.com/xperia-z/development/cwm-based-recovery-6-0-4-6-root-xperia-t2167381

even if it is actualy not supported for the 10.5.1.A.0.283 Firmware. ;) (But it is only needed for installing the superuser.zip)

How to do?

Like i said i made an clean Install.

1. Install the Flashtool

2. Install the needed Drivers (can be found in the Flashtool /Drivers Folder)

3. Start The Flashtool (depending on your System take the Flashtool or Flashtool64.exe)

4. Go to the Devices --> Check Updates Menu and select Xperia Z

5. Then Select your Phone Model, (I took c6603)

6. Select the Variant you have/want (i took the customized UA Version) Double Click on it to see what Version it actualy has.

7. If you found the right, double Click on it to download it, this tooks an little bit of Time. Then the Files are Decrypted needs also a little Bit of time.

8. Than there should open an Window called Bundler. So Press Shift+End to select all files and move them to the right Tab with the "->" Button and click "create"...

9. Now shut down your Phone. And click the Flash Button, select Flashmode. Select the Firmware you want to Flash.

AND HOW I SAID if you want to keep the Data and so on. You must Select or deselect what you need or not at this Point.

10. Press the Flash Button. It tooks a little Bit of Time and than you must connect the Device in Flashmode Press the Volume lower Button and hold it than attach the USB Cable if the Flashtool says it.

After some Minutes Later you have the Latest Sony Software for this Device.

How to Root?

1.Shut down the Device

2. Click the Flash Button in the Flashtool and select Fastboot Mode than you select the boot.img in the Doomlord Tab (select Kernel to Flash). Hold the Volume up Button and Connect the USB. Wait some Seconds than you have this Kernel installed.

4. Disconnect the Phone and switch it on, if the LED lights up press and hold the Volume down key. Than it should start in one of the Recovery tools, there you should choose the supersu.zip which you had copied to your external SDCARD

before

Install it. ;) After that switch the Phone off.

5. Because this Doomlord Kernel does not work with this Firmware Version, you need to restore the Original Kernel from the 10.5.1.A.0.283 Firmware.

Click on the Flashtab in the Flashtool select Flashmode and than select the 10.5.1.A.0.283 Firmware. BUT NOW deselect all in the Wipe Section. And select all in the Exclude section except the Kernel.

So that only the Kernel will be flashed. If you are asked from the Flashtool press and hold the Volume down Button and attach the USB Cable. Than the Flashing begins.

FINISH

Now you should have an rooted 10.5.1.A.0.283 Xperia Z with the Original Kernel :)

There is NO warranty for this HowTo. You should Backup all Data before you do this. You do this at your OWN risk.
