hi pls help me,

i have xuz c6833 14.2.A.1.136 - rooted.

i read and followed all steps from here: http://forum.xda-developers.com/show....php?t=2447319 untill:

....
11. In the cmd windows type in fastboot.exe -i 0x0fce getvar version
12. If a value is returned (it will return 0.5), it means the phone is correctly connected
13. Type in fastboot.exe -i 0x0fce oem unlock 0xKEY and replace KEY with the key which u received earlier. (replaced KEY)

then it says:
FAILED (remote : Device already rooted)

i have tried Xperia Z Ultra Toolkit 1.0 and got the same message FAILED after enter unlock code received earlier via email from sony.

I just used flashtool to unlock mine.

make sure you have backed up your TA partition

from the dialer dial *#*#7378423#*#* somewhere in there in the unlock status, cant remember where and I'm not on stock anymore.

As you bootloader is unlocked you can just load any of the dual-recovery boot.img to get both cwm and twrp. I normally flash jackies one or chillychan's http://forum.xda-developers.com/show....php?t=2575909

I used that to install the dual recovery on my phone using the chillychan's post...

Do this:
Download the kernel-136-dual from his post
Download the SuperSu
Put the SuperSU in the phone SDCard for example...
Shutdown your device.
Plug the usb and press in the same time Volume Key Up
Open flashtool..
Click on the first icon is like a thunder... and select fastboot mode then click on "Select kernel to flash" and get the "kernel-136-dual.img"
And the flashtool install the kernel..
You see in the dialog box..
Unplug the usb cable and turn on you device and press the Volume key Down or Up
My case the Volume Down opens TWRP and then go to "install" and find the SuperSu that you put on the phone.. Install that and reboot
Nothing more to do...
