Hi everyone,
I just bought a brand new Z Ultra C6806. I plugged it into my computer, installed the My Companion software, and then proceeded to root the device via the Chinese root, which seemed to work just fine. I then tried to unlock the bootloader with Flash Tool, but couldn't get Flash Tool to recognize my device. It kept on saying that I needed to install drivers. I'm doing this on a windows computer, and I already navigated to the drivers folder and installed the z ultra drivers.
I then got fed up with that and saw the thread that let you flash a recovery with a locked bootloader. So I followed those instructions and had a working CWM and TWRP. Except then I wiped data and system and flashed the CarbonRom custom rom, and now my phone won't boot at all.
I'm hopeful that everything is not lost since when I hold volume up and plug my phone into my computer I see a blue LED, which I have gathered means that it is successfully still entering fastboot mode?
How do I get Flash Tool to recognize my device? And is it possible to unlock the C6806 bootloader or have I been deeply mistaken all along?
Thanks for any help
[HOW-TO] Unbrick your XZU
You can use method A. Read carefully how to install the drivers and do not use a USB 3.0 port.

You just need to use 'flashtool' and flash a FTF file.
But like you said before you'll need to ensure drivers are installed properly. flashtool will need to say:
'device connected in fastboot mode' or
'device detected in flash mode'
Download the latest version of flashtool. Then when you select the type of device, you can select Xperia Z Ultra.
and make sure that ADB is installed (windows will detect new device has been plugged in, and if it wont install drivers, you will need to tell it where to find them)

Reinstalled flashtool drivers for z ultra and flashmode and fastboot, pointed my windows drivers interface to the driver file I downloaded from the sony unlock bootloader website and still didn't get anything on my laptop.
Did the exact same things on my desktop and everything is working fine now, flashtool recognized my device, flashed a Sony FTF, unlocked bootloader successfully, playing with CM now.
Still not sure why this is the case, but alls well that ends well I suppose, thanks.
install flashtools driver you can find it in Flashtools folder. PC need driver when xzu in fastboot mode.If you use USB 3.0 like me try different usb slot.

Hi Guys,
My first Sony Phone (previous Samsung User). I have the US Version C6806 LTE model. I have a similar question. I have unlocked my bootloader successfully via Sony's website. I want to be able to install TWRP and backup original ROM before applying custom ROMs. Doesn't look like there is a root available for this phone model yet? I am on firmware 14.1.B.2.257. My questions are:
1 - Is there a TWRP image I can flash on my model via fastboot without having root? Then boot into TWRP and backup the ROM?
2 - If not can I flash any of the images that I seen on XDA via fastboot that include the Root and TWRP in them? Or will those not work with .257 firmware?
3- If none of the options above work can I download an FTF image (older version) that I can root and use TWRP and if so which image do you recommend that would work with my phone model and LTE network on AT&T?
Thanks for all your help and sorry for all the questions I am a noob with Sony Phones. I did research here and seems most of the threads and images are NOT for C6806 which I have.
I think all tyour questions are answered in various threads in the X-ZU forum...
You have gone about it all ass about face, you should have downgraded to .532 then rooted with kingo (looks like is is safe?). Once rooted you should of then backed up your TA partition in case you ever need the phone serviced.
I dont know if TWRP is working well in any of the boot.img but CMR works fine (except for the date of the backups)
any of the firmware/ftf/ROMs will work with any of the Ultras as far as I know

I flashed a .532 firmware still no safe root method from what I can tell. Looks like I need to flash an earlier version or a FTF hopefully that contains root and custom recovery. I will keep reading and researching. Thanks for the help.
do you want to end up on a rooted stock firmware?
as you have already unlocked the boot loader you can just flash one of the kernel/boot img with recovery and then flash whatever rom you want from there...
I also run into Cyanogen Recovery and have trouble going back to FlashTool with my chromebook. I am a bit panicky, but your post is comforting and ensuring.
I got the C6806 xperia z ultra in year 2014. I have been using it as a home primary PC.
My blog about this amazing device, is http://nocomputerbutphone.blogspot.com/ .
This is the latest Flashtool 0.9.13.0:
Download here: http://ul.to/sb8cfqyr
Flashtool is a S1 flashing software that works for all Sony phones from X10 to Xperia Z Ultra. They all use the S1 protocol for flashing firmwares.
This program was originally made to flash sin files downloaded by SEUS or PCC. From time to time, sin files have been bundled into what is now well known FTF (Flash Tool Firmwares). That is the core of Flashtool and the reason of its name.
Flashtool can also easily unlock the bootloader of the phone using the BLU icon as far as the bootloader of your phone is unlockable
The flashing feature as well as bootloader unlock feature are available whatever the phone is recognized or not by the application. What is only mandatory for flashing is to own the FTF file according to the device you want to flash it on.
Why should I use flashtool ?
Once bootloader unlocked, official sony tools do not work anymore.
Using official sony tools, you can only upgrade. No downgrade possible.
Using flashtool, you can choose what to flash and what not to flash. This said, many rooting scenarios are available implying kernel only downgrade to retrieve a patched rooting exploit and then flash back the right kernel.
You said unlocking bootloader ?
This process gives you the opportunity to flash custom roms such as CyanogenMod ROMs.
I invite you to visit the FXP Project that brings CM to xperia devices.
Many other features have been built-in so that Flashtool can also be used to (as far as the phone is recognized by Flashtool) :
Root your phone
Install recovery, busybox, custom kernels
Clean your rom (remove /system/apps apps of your choice) (Be careful, unless you really know what you do, do not modify the default list. This can make your phone stuck at the SE Logo)
Clear dalvik cache
Optimize (install of JIT v2) (plugin for 2.1 phones only from 2010 line)
Customize (installs apps found in the custom/apps folder of the flashtool)
Edit any text file on the device
Rebrand your device

First you need to check to see if it is even unlockable. *#*#7378423#*#* software configuration if you can see Bootloader unlock allowed: yes your in luck
If it says Bootloader unlock allowed: no you won't be able to root the device.
Then just follow the instructions for the single sim model on Sonys Web site it goes off the imei no I do believe, so it'll know what model you have. Don't forget to go in developer options and turn on OEM unlock. There's no way to back up ta keys either so once they are gone they are gone that's why I'm waiting.

Looks like no one has shared much about the XA Ultra F3216
If you have not found a solution to your problem with root info let me know. I think we need a couple threads on this model because it seems to be vey different than the others of its family. I am rooted and loaded with Xposed but it was and is a large work around.
This video shares hot to root the F3112. The process is the same but the source files are different.
YouTube video: Xperia XA root guide
To clear the default encrypted partition: When you are in TWRP recovery, wipe userdata partition. The new one will not have encryption.
But a big problem i have found no solution for yet is...
I am not able to boot into TWRP without flashing the recovery then after using TWRP I have to flash the boot.img b4 I can boot into the system again.
So I flash recovery from my computer. Do everything I need to do in recovery then while in recovery I need to flash the boot.img then install root.zip clear catch then reboot to system.

Hi all,
unfortunately I cannot post this message on the sony cross device dev thread since I am a relative new member and cannot post in the dev threads. My question actually is related to the following thread: https://forum.xda-developers.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904
I want to flash a pre rooted lollipop with latest firmware from Sony on my Sony Xperia Z Ultra. For that reason I used the PRFCreator.
I did the following:
I downloaded with Xperifirm the latest firmware for my Sony Xperia Z Ultra. I downloaded the following version: C6833_Customized CE1_1276-2235_14.6.A.1.236_R4D
I created the ftf file according to the steps outlined here: http://www.xperiablog.net/2014/08/1...re-files-using-xperifirm-and-flashtool-guide/
The last step was to use the PRFCreator as outlined here: https://forum.xda-developers.com/crossdevice-dev/sony/tool-prfcreator-easily-create-pre-t2859904
I used the following sources
- For SuperSU: SuperSU-v2.46.zip
- For Recovery: ZU-lockeddualrecovery2.8.26-RELEASE.combined.zip
I rebooted the phone into TWRP, made a wipe and installed the zip file which was created before with PRFCreator. Unfortunately the phone does not boot after the flash. No LED is lighting, screen is black and no boot logo to see.
My bootloader is unlocked.
When I flash the self created ftf file with the flashtool (without SuperSU and without recovery) the phone boots. Can anybody help me whats going wrong and how I can created a pre rooted firmware with latest sony firmware for my Sony Xperia U Ultra?
With TWRP Log
Here is the TWRP Log: https://pastebin.com/FJcpyT3p
What seems strange to me:
Code:
Couldn't find partition with matching uuid
run_program: child exited with status 1
about to run program [/tmp/sinflash] with 6 args
Kernel flashed.
Before I flashed the prerooted ftf file I did the following:
I flashed C6833_14.1.B.1.532_NUT.ftf
I rooted the device with the following method: Bin4ry's "Root MANY ANDROID"
I installed ZU-lockeddualrecovery2.8.26-RELEASE.combined.zip
Hey have you tried kingroot then removing it with super su method?

I figured out that the problem was due to an older twrp build. After I used TWRP Version 3.0.2 for togari it worked. Unfortunately I can not use dual recovery but that is not a big issue. I followed the following guide to install TWRP 3.0.2:
https://forum.xda-developers.com/xp...ent/twrp-recovery-2-8-7-0-2016-02-03-t3307043
With this version I could install the image made by the PRFCreator.
