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

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......

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
Does anyone have a link to a flash tool they know works with D6503?
Thanks

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

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/ .
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?
Root the M4 Aqua E2303 Locked Bootloader/Install TWRP on 2.167/3.92
Before we begin:
Make sure you have the following:
•A Windows PC
•Flashtool (https://drive.google.com/file/d/0B_d8uWGbkaetTnhWX0J5UG5hN28/view?pref=2&pli=1)
•The .128 firmware (https://drive.google.com/file/d/0BzVQf67OZ9NtMFotOXRycTZoSlk/view?pli=1)
•Patience
•A good internet connection
•15 to 20 minutes
• The M4 Aqua Root Toolkit (https://www.dropbox.com/s/edse0h6b02odzn1/rootkitXperia_E23xx.zip?dl=0)
•ADB Drivers (https://drive.google.com/file/d/0B0MKgCbUM0itNVB1elljU2NPR0k/view?pref=2&pli=1)
•TWRP Toolkit (https://www.dropbox.com/s/yomdwq3p2le9hvi/M4Aqua-lockedTWRP-0.1-installer.zip?dl=0)
How are we going to do it:
The procedure is pretty straight forward, as the M4 Aqua is only on Android™ 5.0 we can take the kernel of the older versions of firmwares so we could root the device, while keeping the firmware version to the newest release (2.167/3.92). The method has been only tried on the E2303, there may be chances of it working for the E2306.
Let's begin! Part 1, Changing the Kernel:
First, we need to install the latest Flashtool version (link above), after you proceed with the installation of Flashtool, you need to install the Flashtool drivers, which can be found in C:/Flashtool/drivers or the path you selected flashtool to be installed. Once you open Flashtool drivers you want to select FLASHMODE DRIVERS, this is only so that the M4 will be recognised while in flashmode. After the drivers have been installed, you want to move the downloaded .128 firmware to C:/Users/*YourName*/.flashtool/firmwares or you can use the other method I will show later. Once you have done that you want to open Flashtool and wait for the Sync to finish. After that has finished, you will see a lighting icon in the top-left corner, you want to press the icon and select flashmode, now the second method, at the top you will see a path leading to the generic .tft folder in which Flashtool belives the .ftf files are located by default. You can change that by pressing the button on the right and lead the program to the path of the .128 ftf file. After you have selected your .tft file you will see on the right a lot of options *everything that the .ftf file contains*, if you want to keep the data on your device you can tick the first two options, a bit down on the right you will see a lot of options, including system.bin, you want to tick everything EXCEPT for the kernel.sin, this is the most crucial part. After that is done you want to let the program prepare the files, mean while you want to power off your M4 Aqua, after the process on Flashtool is done you want to press the VOLUME DOWN button while connecting the phone to the PC, once you see the green led light you can leave the button, if everything was done right the process of flashing should begin. If everything went well the kernel should be flashed and the phone should safely power on. Now we can proceed to the second part. Rooting the phone.
2ND METHOD
You can downgrade to .128 firmware and download the .167 or .92 firmware and update everything except for the kernel. You can do this by going into Flashtool, and doing the steps above but TICKING the kernel.sin. Try this if the first method doesn't work.
Part 2, Rooting the phone:
Now that we have changed the kernel we can use the root toolkit to root the device. Download the root toolkit from the link above, but before you do anything you want to go to Settings>About Phone, scroll down to Build number and press it 7 times, after that is done you want to go back to Developer options, and you want to tick USB Debugging, after you have done that you need to install the ADB Drivers from the link above, after that is done you can connect the phone to the computer, now you want to extract the toolkit and run install.bat *No administrator rights needed*, and then you should see a screen on your phone asking if you want to trust the computer, you want to tick the box saying always and you want to press yes, now the rooting process should begin and your phone to be rooted. After this is done we can proceed to the part 3, installing TWRP
Part 3,Installing TWRP:
Now, that we have root we can install TWRP using another toolkit. This part is optional but if you want any custom ROM's you need this. This part is the easiest, you need to download the toolkit from the link above and just run the script. We don't need any additional steps as we did them in Part 2.
If everything went well you should now be rooted and have TWRP with a locked bootloader and on the newest firmware.
In case of bricking you can use the Sony PC Companion tool and repair my phone/ tablet option. YOU WILL LOSE ANY DATA SAVED ON YOUR PHONE.
sir , can this apply to D2353?
I have only tried on E2303, but you use the right .ftf files the procedure should work

Root and flash stock kernel tft u use
I'm having issues with this also. Downgrading the kernel only causes a boot loop animation. I can downgrade everything to 128 and it works. Going back up to latest with everything BUT kernel causes boot animation loops also.
EDIT!
Oh heck yes, I did it! For anyone stuck in a logo boot loop despite following the above, here is how I did it:
- Use Flashtool to completely flash my .167 E2303 to .128.
- Use above tools to root and install TWRP.
- Use Flashtool again, but this time in Fastboot mode. I extracted the system.sin file from a .167 ftf and then flashed system using Flashtool.
- Reboot the phone into TWRP. Clear cache, dalvik. I did NOT clear data.
- Install M4 extras. Install AOSGP. Clear cache, dalvik.
- Reboot took about 15 minutes, probably less.. and BINGO.
Thanks to all.

When i upgraded from 128 to 167, phone works well but random reboots. Any fix this issue?
Clean install of .167 and .92. Flashing the .128 kernel causes the blue boot animation to hang (the start up sound cuts off half way). Flashing the previous kernel back over works.
Same happens when I flash .128 then everything but the kernel from .167 and .92.
Unsure what the FSC script option does, but yes or no makes no difference.

If your random reboots usually happen while downloading or updating apps in the play store, you should try this. Make sure you backup your data first just in case.

Hello. Please help. I got softreboot everytime I try to call someone
Sent from my E2303 using Tapatalk
Hello,
thank you for this guide. I have a question: why not extracting the old kernel and just flashing the kernel.sin?
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!

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 ?

Sorry, I ditched my Z2 for a Oneplus 3 in August 2016. Learnt my lesson, only going to use phones with easily unlockable bootloaders.
Soooo my phone, broke the USB port out, taking half the board with it, so it couldnt get soldered back since it didnt have the board to support the sides, it would break off again.
It works, but now i wanted to update the firmware and found it i cant since Flashtool is USB only, is there a way to flash the FTF from the phone itself? Its rooted and has all the usual stuff that guides usually make u install (teamwinrecovery) or should i update through the stock method (official download through the phone) but then, how would i root the phone from official firmware? Do i lose it? Can i regain it without USB? Thanks in advance
Ok its been a while so i had no idea, i updated myself and now im in 5.1.1 with root and recovery, i just flashed a zip from one guide. Now im looking at 6.0.1, problem is theres a always a step about using busybox and install.bat from the recovery folder.
Is this to install the TWRP again? Is it only installed through the PC and USB? Or would my old recovery remain from before? Or is there another way to install the TWRP?
