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.

Title says it all...almost.
Was already rooted on 4.4.2.
I did a TA backup.
Then I followed the instructions located here to get custom XZDualRecovery .
All worked great!
Was able to boot into TWRP and Philz successfully.
Performed a full backup in TWRP onto a thumb drive over OTG cable.
Then wiped everything via TWRP in preparation for a CM11 rom.
Rebooted before trying to flash CM11.
Now can only boot to sony logo, fastboot, and "System Recovery" mode. (the mode that has 'continue power up' 'safe mode' 'factory reset' and 'power down'
I, like all the other noobs who didn't RTFM, missed the ''Be sure to flash XZ/ZL/TabZ/Z1/ZU-lockeddualrecovery[VERSION]-BETA.flashable.zip from http://nut.xperia-files.com after installing the ROM and before you reboot, this way you will not lose recovery!'' part of the XZDualrecovery post. =(
Now, my questions is, what if you DID forget to flash dual recovery after wiping?
What happens now?
I am thinking, is there a way to flash XZ/ZL/TabZ/Z1/ZU-lockeddualrecovery[VERSION]-BETA.flashable.zip via fastboot?
If so, how?
Thanks for your time and be gentle.
after 8 days with no help, I read 10 different threads on 10 different issues that KIND of pertained to my problem.
Wrote all Pertinent info down on a sheet of paper over the course of 4 days of searching.
And then started piecing together a solution.
Here's what I did to fix my issue for anyone who has the same problem.
1. Download xperifirm and select correct firmware for device
2. used Flashtool to convert above downloaded firmware to FTF
3 put tablet into flashmode
4. flash FTF file via flashtool
5. viola!
Thanks..I think.

I do have a question about the ''you can use flashtol to download your carriers latest ftf" part.
are you referring to being able to download the firmware from the flashtool site here?
Or can you actually do it directly from the flashtool program?
My 2 problems are, 1. I do not see ANY firmware for my SGP561 (verizon) tablet on the website
and 2. I do not see any options for firmware download in the flashtool program
EDIT: Found it! Flashtool program > Devices > Check Updates
Is there a way to flash downgrade your firmware to a lower build number so you can officially unlock through Sony's dev site?
Hi, everyone, I just got my z3 tablet and I am in love with it except i don't like the interface. So i decide to root my tablet without unlocking the bolted and I did made it and i did install TWRP. I have a question, since I have TWRP is it possible for me to install cm 12 rom or I need to have a unlock boot loader in order to install it?
Sorry for my bad english and thank you for answering my questions.

You need to unlock to flash a custom kernel which would be needed by the cm12 to run. So first.
1.Backup drm keys
2.Unlock BL
3. Flash CM kernel via fastboot
4. Flash CM Rom via recovery.

I just bought a Z3 tablet compact, which should be here at the end of next week. I haven’t found a tutorial which includes all steps to get from the standard rom to CM12. Did I miss any steps or does the following steps include everything?
Root tablet on the original Sony rom
Backup TA partition (I guess that's where the DRM keys are?)
Unlock bootloader
Flash a recovery (any recommendations?) I found this tutorial, but I only need one recovery and I don’t want to flash that zip every time I install a new rom.
Flash CM12. Are there any kernels beside that one included in the CM12 zips?

I guess you should just flash the kernel via fastboot after unlocking the bootloader, that would eliminate the need to flash a recovery. It's hitting 2 birds and one stone and besides CM uses a different kernel than stock so later you would really need to flash kernel.

Thanks for your reply. The whole flashing procedure is a lot more complicated than on my S3, so I have a follow-up question.
Should I just backup the TA partition, unlock the tablet, flash this kernel which should give me root and TWRP and then flash another recovery and CM12?
I found this recovery which is only semi-permanent, because you have to flash it before you upgrade/install a new CM12 version. It’s not big deal tbh, but is there a permanent recovery, which I only have to install once.
I'm also curious about this.
Right now, I'm trying to download the Flashtool program from Sony, but apparently, you need to "register" for it. Where did you guys download your Flashtool from?

The whole procedure is really frustrating, maybe someone can help me here.
I did a backup of the TA partition and unlocked the bootloader. I tried flashing the boot.img from the cm.zip, but I have no idea how to flash the rom via the cm-recovery.
Flashing the advanced kernel to get TWRP wasn’t successful as well. I tried the fastboot mode of the Flashtool and flashed the kernel, but nothing changed.
Can someone post a brief guide with the next steps to get CM12 running (with cmd commands pls)?
EDIT: I just tried to use “adb sideload” in the CM recover, but “adb devices” doesn’t show the tablet .
EDIT2: EDIT: Seems like I got it to work after all. The DualRecover Installer worked, even without SuperSU installed.

I ran into the same problem usin the cm12 nightlies from 27th march 2015:
Sideloading would not work because the tablet is not recognized by the computer. I tried with Windows 7 and gentoo Linux.
Installing from the sd-card in recovery mode was also not possible due to a error of missing "/misc".
I solved the problem by manually choosing the driver in Windows 7. I booted the tablet into recovery. Choose update using adb as detailed in this post:
http://forum.xda-developers.com/z3-...t/root-root-locked-bootloader-sgp621-t3013534
Then I found the device in the windows device manager. Here I manually choose the adb driver that I installed earlier from the flashtool package. After that the device was correctly recognized by Windows and I could Sideloade the cm12 image.
Installing the new Sony Bootloader and Recovery
THIS IS FOR ALREADY UNLOCKED DEVICES!
DO NOT TRY THIS ON A GPE!Since a lot of people seem to have problems keeping their recovery when flashing Lollipop-ROMs i decided to put up this little guide...
You can also Skip this whole guide, by just flashing the newest stock-FW at least once!
First off, as already said, this is for already unlocked devices. You can use this Guide until "Install Custom ROM", except the rooting part, for rooting use this, if you haven't already!
Don't do it if you don't atleast somewhat know what you are doing.
I am not responsible for bricked devices, or whatever you might end up with.
So, lets get started.
1. Download Sonys FlashTool "EMMA" and install it: http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/
In the .zip file from the FlashTool you'll find a File "customization.ini"
Copy this file to the installation directory of EMMA, usually "C:\Program Files (x86)\Sony Mobile\Emma"
If you don't copy that file, Emma will ask you for a login, don't create an account there, you will NEVER get any activation-email!
2. Open EMMA and boot your Phone into FlashMode (Power off your device -> Press and hold volume DOWN -> while pressing volume DOWN insert USB-Cable)
3. Emma should now recognize your device, but you have to select it manually tough. Select your EXACT model number. Again, I am not responsible for any bricked devices or whatever you end up with!
Now select the "(Open Devices) TA update" and click "Apply Service"
It should take a few seconds and should then display SUCCESS.
You can now close Emma
4. If you haven't already download FastBoot and Drivers: http://forum.xda-developers.com/showthread.php?p=48915118#post48915118
(Run as Administrator!)
5. Download the newest version of twrp and put it somewhere:
New Inoffcial twrp-3.0.0 build by me: http://forum.xda-developers.com/xperia-z-ultra/development/togari-twrp-recovery-3-0-0-t3314440
Old official versions: https://twrp.me/devices/sonyxperiazultra.html
6. Finally boot up you Phone in FastBoot-mode (Power off -> press and hold volume UP -> while pressing wolume UP insert USB-Cable
Your LED should now light up blue
Shift+Rightklick in the Folder where you have put TWRP recovery, and select "Open Commandprompt here"
Now write "fastboot flash recovery FILENAME_OF_TWRP_FILE"
You can now unplug your USB-Cable and boot into recovery and continue from there.
Your recovery will be permanent, meaning you won't loose it or replace with any other recovery that might come with your ROM.
I hope this was somewhat helpfull

tried, but no luck. thanks.
It's really weird, I used emma, and installed their latest ta update. Now I can get into fastboot mode, all commands execute successfully, but the recovery never takes. The vol down + Power doesn't work, nor does 'adb reboot recovery'. Am I missing a step somewhere? This isn't my first android device, but from where I sit, it seems like something is up with my xzu.
If I try and install the 14.4* update through emma, it goes through the whole process, completes "successfully", then boots into 14.5. Something is clearly not working here.
The TA update only unlocks the ability to boot to recovery, it doesn't install one. And no, flashing official TWRP to recovery partition doesn't work, it must be compiled again to work on normal recovery partition and not in FOTAKernel, where it must be flashed to work.
Regards

I´m on CM 11 M12 (looking forward to 12) + the new sony bootloader without any custom Kernel stuff.
Sadly, you are right. It´s not done with downloading twrp-2.8.5.0-togari.img and fastboot flash recovery yourfile.img.
The last offical TWRP release for Xperia Z Ultra is from february 2015, any chance they release an updated version for the new Sony bootloader?

Is there any (wish for TWRP) recovery for togari, which use the new bootoader?
FYI:
My device is a brazilian c6843.
Emma recognizes the device automatically and indicates with an exclamation point that there is no services available to the unit.
In the case someone doesn't know, it's basically the c6833 with DTV 1seg. It's totally compatible with c6833 firmware, losing TV, of course.
You sir are the real hero! Thank you!
I have a xzu running cm12.1, and I have 2 quick questions for those with more knowledge than me
Is it possible to flash the new bootloder using the open source FlashTool?
If I have to use emma, is it possible to just apply the open device ta update *without* installing stock firmware first?

You can totally do that, BUT, the newest stock firmware also has some firmware updates regarding nfc, also having the newest stock rom flashed at least once will be kind of a requirement to get everything properly working on marshmallow roms.
So I would say flash the newest stock rom at least once!

I followed your advice, but it seems I am missing a few clues.
My sirius was on cm12.1. I backedup and flashed D6543_23.4.A.1.232_1281-5466_R6C.ftf with flashtool on linux. I tried to use emma (several times) afterwards to check for any TA updates, but all I got was "no services matched this device" or something like that. Google tells me I am not the only one with this issue with emma
Then I used fastboot to install twrp 3 from twrp.me to recovery partition, but I could not access twrp.
I fastbooted recovery again with twrp 2.8.7, and this time I could enter twrp and reflashed CM.
Now I can access twrp using the button combinations while booting, but rebooting to recovery from CM leads to a bootloop. Has anyone experienced this as well?
So it seems I am still missing a few clues to using the recovery partition. Is any build of twrp supposed to work on both FOTAkernel and recovery partitions?
Is there a TWRP 3 build that works from 'coldboot to recovery' and 'cm reboot to recovery' with the new bootloader? Any pointers?

Well, booting to recovery on separate partition from os, requires the rom to have a patch... the "new" mm-roms (when they finally hit aka. are ready to be shared in public) will have that, so no worry, just wait.

Search the forums on how to backup TA partitions. I have mine but never tried to restore them
Yes, like many before me I have made that mistake of ticking the system box when wiping my Sony Xperia z2 via twrp.
The issue that I face is this:
I no longer have a backup so cannot revert back. My phone is no longer rooted either so when trying to install my rooted firmware, twrp tells me to install supersu. When doing this the phone simply turns off.
I'm sure the simpliest way to get back up and running would be to flash a stock unrooted firmware in twrp, however I can't seem to find the relevant file to do this as also understand a ftf file cannot be flashed in twrp and must be done via flash tool.
I have downloaded a stock ftf firmware for my phone (D6503)
and flash tool, what I thought to be the latest version. ( 0.9.19.0 )
I have installed ticked all relevant boxes to install the drivers which windows tells me was installed correctly. However when connecting my phone to flash tool with volume down held, tells me no drivers are installed.
Any help or advice would be greatly appreciated as I'm slowly pulling my hair out
Adam
Root isn't needed to install new system if you're already running twrp, so maybe you just have to use proper recovery.
And about the drivers. Are you on Windows 8 or higher? Because then you have to launch your pc without driver signature to properly install them.
Also how did you install them (did you use the ones included with flashtool)?
One more thing. The firmware version you've downloaded is pretty strange, make sure you've downloaded the correct one. It should rather start with something like 23.A......

Luckily not from an iPhone = Yesterdays technology at tomorrows prices
Thanks for the reply.
Sorry I didn't make myself clear, when I referred to the download I was on about the flash tool. My firmware is as you say 23.a etc. Its lollipop
I'm currently on windows 7. Yeah I went into the drivers that were provided with the program and installed them from there. I've still got the original file I used when rooting my device but when I wipe the cache etc and then flash the file, it installs fine but gets stuck in boot up. Just the purple background moving about.
I'm fairly sure it says my boot loader is locked too now as when I wiped everything I was also returned to stock, so not sure how to go about that or if that is my issue.
Thanks again
Try to uninstall and reinstall drivers, and reboot the system after each step.. If it fails, borrow a laptop from ur friend and try again

Long story - Tried to apply the latest Marshmallow rooted package for D6503 on my 6502 that was already rooted with XZ dual recovery. It installed successfully, was rooted too...but I forgot to add the patch that would fix the radio not working. So I try to reboot to recovery...and that doesn't work anymore. I tried installing TWRP recovery from the manager app, but it wouldn't reboot. Then I ran the XZ recovery installer externally, and now my phone is ****ed. Stuck at an infinite boot loop.
At this stage the only thing I can access is flashtool and fastboot, and since my bootloader is locked I can't flash a recovery that way (nor do I want to permanently lose DRM keys/camera quality as I've heard happens with unlocking the bootloader). I have a memory card and I used the option to disable loading the recovery specified on the XZ thread by adding a 'donotload' file on the sd card.
Still no use - I get a Sony logo for about 5 seconds, the screen goes dark and back to the same. At this point probably my recovery is screwed up or non existent and a bad situation has gone worse with the bootloop.
What can I try now?
@KaiserSnorezay
XZDR is still not compatible with MM, that's why you got a bootloop...
Also you can't install the "regular" TWRP with twrp manager on a LB as there is no recovery partition... it won't work and probably will mess your phone in the process.
The solution is to flash any KK / LP .ftf with flashtool (i would wipe everything when flashing as i have backups of my data/apps) , root it with kingroot or any other method you like, install xzdr for KK/LP and finally reboot to recovery and install the latest MM prerooted rom from niaboc which already has root&recovery (not xzdr btw) included. Since you have D6502 don't forget to install the baseband patch after the rom again
http://forum.xda-developers.com/xperia-z2/development/rom-official-6-0-1-23-5-0-486-beta-t3336770
Just did it exactly this way yesterday on my friends d6503 (minus the d6502 patch obviously) had 0 troubles MM, root and recovery working perfectly.
Thanks, will try this today. Is wiping data required or can i get by by just flashing the older one?

Weird, after you have your phone rooted it should be simple to install xzdr... just enable usb debugging in the phone and make sure you have the adb drivers correctly installed in your pc.
Download the latest xzdr from nut's thread ( http://forum.xda-developers.com/showthread.php?t=2261606 ) unzip it and run install.bat . After a successful install the phone should reboot to twrp automatically and it's done.
Okay, I fixed it..using Flashfire! No idea why the recovery didn't work earlier, but now finally I'm on Marshmallow. Thanks for the help!

hey bro, just read your post. Yesterday i got an update msg in my software update menu of my Xperia Z2 D6502. After i updated i went into bootloop. i have very important stuff in my phone. i updated earlier too all the updates that sony servers inform about. so then i thought to flash with the stock file. Although i didnt knew the firmware number , i just flashed with 5.1.1 , 1st with Customized IN & later with of US. Both of them didn't work as well. Please help me out. I'm not much aware about this root stuff & all. hope to get reply soon from you or anyone in this forum.

Try what ptmaniac suggested - flash an older FTF that can be rooted (more recent ones can't), root it, install recovery and then flash the newest build.
You'll have to improve your Google-fu to find a suitable firmware and a root technique for it.

okay. you mean flashing any old firmware ( which i did and still in bootloop ) & root it. Then installing recovery for the same firmware ?
with "recovery" will i be able to get back my whole data ?

Long story - Tried to apply the latest Marshmallow rooted package for D6503 on my 6502 that was already rooted with XZ dual recovery. It installed successfully, was rooted too...but I forgot to add the patch that would fix the radio not working. So I try to reboot to recovery...and that doesn't work anymore. I tried installing TWRP recovery from the manager app, but it wouldn't reboot. Then I ran the XZ recovery installer externally, and now my phone is ****ed. Stuck at an infinite boot loop.
At this stage the only thing I can access is flashtool and fastboot, and since my bootloader is locked I can't flash a recovery that way (nor do I want to permanently lose DRM keys/camera quality as I've heard happens with unlocking the bootloader). I have a memory card and I used the option to disable loading the recovery specified on the XZ thread by adding a 'donotload' file on the sd card.
Still no use - I get a Sony logo for about 5 seconds, the screen goes dark and back to the same. At this point probably my recovery is screwed up or non existent and a bad situation has gone worse with the bootloop.
What can I try now?

Sorry, I ditched my Z2 for a Oneplus 3 in August 2016. Learnt my lesson, only going to use phones with easily unlockable bootloaders.
