I'm not really sure if you mean "flash" by "root" but yes. You can flash any stock ROM as long as your bootloader is locked. Your data will be wiped and you will no longer have root access.
It will be like a brand new phone. :silly:
Go check some guides on how to flash back to stock with flashtool.
Use Google for NSIS error fix. I think there are alot of guides aswell.

You need to use XperiaFirm software to download the official ROM and convert it into ftf.
Here are some Tutorials from @mrjraider
http://forum.xda-developers.com/crossdevice-dev/sony/tutorial-downloading-firmware-convert-t2837097
http://forum.xda-developers.com/showthread.php?t=2658952
Just read carefully and read the steps.
P.S. If you have unlocked your bootloader, you need to restore your DRM Keys, then lock it again.
Good Luck!

There is no direct method to root the phone. You need to downgrade first. Use this guide to get root on .290 first:

Just unlock the freakin bootloader already like i did last night. and use flashtool 9.11 instead of 9.13 for some reason it keeps installing the wrong driver for the phone which results in a header error.

I don't know if you know that the v.9.11 is not recommended with Z1 and you risk to brick your phone. Unlocking Bootloader is needed for Custom Kernel only and if you do that you will lose Warranty and some features. Just follow the Video and you will be fine. BTW, windows installed the drivers for me and all was fine.
Get the root

The finally way to get full Root was:
Downgrade to .134 (NUT's provide) Root and Install the last XZDual Recovery (NUT provide)
In TWRP Flash iHakers 2.1 (minimal) Before boot to system, Flash Lastest XZDual Recovery (NUT provide) and flash lastest Supersu Zip Flashable (Chainfire provide)
Boot to system and restore all my apps with TB open each and every one app that needs root to get it (root)
Go back to TWRP and Now Flash .136 (NUT provide) With only wipe cache and dalvik cache (this is important because is the only way that a could gets the root in .136) Flash again last Supersu.zip flashable.
Turn off my phone And flash the properly stripped.ftf provided by NUT, turn on my phone and get full root.
(in other ways only gets partialy root)
In the NUT thread some people have same problem like mine (Even NUT comment it)
Sorry my english, to bad
Thanks all for your help.

In Flashtool uncheck "Wipe Data". In PC Companion use Backup & Restore, Update and if you lost something Restore with PC Companion.
Guys i got the phone recently, i unlocked my bootloader yesterday and i am on 136 now... I dont want to bother with downgrading and so on but i don't have root nor recovery... can't i just flash something rooted with flashtool so that afterwards i'll be able to just flash through recovery on the phone?
I moved from an Xperia S and none of these issues existed there...
Thank you in advance.
Oh nevermind gentlemen, thanks for the help
I Solved the issue by simply installing Ihackers advanced kernel.img trough Flashtool with the fastboot method... Pretty simple it got me an instant recovery and trough it i rooted and then installed SuperSU from the playstore... I finally understood the general concept...
P.S. I am with an unlocked bootloader so thats why i managed to install the kernel...

[Q] Back to 4.1

Hi experts,
before i try the new 4.3 rom i would like to know if it is possible to revert back to 4.1.2 later on.
Thanks

Of course. Flashtool + appropriate FTF file which you can find anywhere in this subforum and you can easily revert back to 4.1.2
Thx
Thank you,

Which needs unlocked bootloader, correct?
Which additional drivers need to be installed?
Is there a way to downgrade with locked bootloader? I am actually ok with the function of .199 but not with it's tons of bloat, and no way to install certain apps. No root is almost like having no sex ever.

Of course yes, flashtool is both for locked and unlocked bootloaders! The drivers I always install is something called "Gordon Gate driver", the FlashTool itself and this is enough for the phone to be recognized while plugging. Be sure to plug in the phone one time in flash mode before the final flashing so that the PC recognizes it and installs drivers, after that unplug it for a while and turn it off again because it will probably turn on, it always happens in my case when I plug the phone for the first time after f.e. installing a brand new OS and not every drivers are installed. Then run FlashTool and you can start the magic!
But, you can always disable certain apps in Settings>Apps>All. You will be actually freezing them (just like with titanium backup) but it's pretty useful. Aaaaand there are two ways of flashing recovery on locked bootloaders so that you can i.e. flash SuperSU .zip file with the app and appropriate binaries (you can find it on its dedicated thread here on XDA), that's what I'm always doing.

Ok, I have still a notebook somewhere in the corner running XP. I'll see what this one can do. If I can downgrade to 4.12, then I can rrooooot that one. At least I would not feel so naked and vulnerable anymore.
Can Flashtool make a mirror or image of the current ROM?
And thanks bunches for your helpful answer!
Here are the rough steps to downgrade:
- use a PC which runs Windump XP or 7
- install Flashtool
- install drivers (in the Flashtool drivers folder)
- download a 4.12 FTF of your choice. Nordic and Singapore seem pretty good.
- switch phone to USB debugging
- open Flashtool, click on the flash symbol and chose flashmode, follow the instructions, don't disable any of the flashing options
- after successful installation root with DooMLoRD_Easy-Rooting-Toolkit_v17_perf-event-exploit
- after successful rooting update SuperSu
- install recovery CWM4XperiaT_v8i_JB
From here you can install a rooted 4.3 if you can live with it's shortcomings, or any 4.2. I choose Pure-X-Blaster 4.2.2.

[Q] Rooting from Android 4.3

Hi,
I, after the long wait, foolishly updated my Xperia T to Android 4.3 (build 9.2.A.0.295). Before doing so I made a nandroid backup of my 4.1.2 install (can't remember what build). Only now do I realize this mistake as the current method for rooting requires you to start from a rooted Android 4.1.2 base. So this leaves me in a situation with a lot of questions that need answers.
Firstly, is there a back up technique that I can use (instead of nandroid) that doesn't require a rooted 4.3 device? And if so to what level does it backup (i.e what will I lose)? Or can I create a nandroid without a root? I would like to be able to use it as a safety net so that I don't lose everything if I screw something up.
If there is such a method I would like to root my device but I have been unable to find any instructions rooting from 4.3 for newbies like me. The current post by DaRk-LOrD just says "Install 4.1.2". How do I do that? Is it possible I can just skip downgrading and somehow go straight to installing CWM on 4.3 (I might be talking garbage, I don't know...)?
Also if I am to root I would like a way to get as close as possible to my current installation of Android 4.3 as possible (apps, app data, settings, etc.). How would I go about doing this? Maybe I install Android 4.1.2 from my nandroid I made before updating?
Also, does anyone know if it is likely we will be seeing a tool such as this one for Xperia T 4.3? Maybe if such a tool is in the works I should hold off for a bit longer.
I know these are a lot of question but I have been unable to find this information which is either relevant or applicable to my situation or what I find is just too complicated (steps are too broad and assume too much prior knowledge). If I have left out any information you need please don't hesitate to ask.
Thanks,
JamesStewy

I have a short answer for you: 4.3 is not ready for prime time.
I recommend downgrading to 4.12, root it, install CWM, then flash another ROM of your choice. Look for downgrade to 4.12 threads, such as this:

Is your bootloader locked, or unlocked? If it is unlocked simply flash a custom kernel. Then flash the supersu zip file you can find in this forum. Next step is to flash the kernel from the ftf file, make sure to exclude everything else.

I do have an unlocked bootloader.
Does the steps you have outlined above root 4.3 with out a downgrade? Will this process wipe my phone (if so how can I get it back afterwards)? Also, where can I find "a custom kernel" (which one?), "supersu zip" (like the one from Dark Lords post? What version of supersu?) and "the ftf file" (the Xperia T, Android 4.3, build 295 ftf file?) ??? Sorry but I am too new to this to understand exactly what you are saying from what you gave me but it does sound like what I want .

1. You will not have to downgrade
2. It will not wipe your phone
3. Download for example CM or Omni rom, extract the kernel and flash it via flashtool
4. http://download.chainfire.eu/382/SuperSU/UPDATE-SuperSU-v1.93.zip
5. Yes, the Xperia T .295 ftf file, if you were using it before

Is there a way of doing this without CyanogenMod or OmniROM? I would really prefer to just stick with Sony's 4.3 just rooted.
You need a custom kernel with a recovery. If you already have a custom recovery installed you can skip this step

"custom recovery"??? Sorry....
Can this be achieved from a what is basically a stock install of 4.3 with a load of apps on it?
You said that you did a nandroid backup. I'm pretty sure you did this in a recovery. There has been a guide of how to root stock 4.3 with unlocked bootloader. Search for it here and you will find it. If you have any further questions feel free to ask.

It was a nandroid of 4.1.2 from an app. Can I make a nandroid of my 4.3 install without a root (that would be awesome)?
I will search for that post.
No you can't
This post is for TX (i would assume it is adaptable by downloading the T versions of the files) but it does say wipe personal data in the instructions which isn't really ideal.
There's Dark Lords post which I found originally which goes through the steps of having 4.1.2 installed and it it also says "do a factory reset" which isn't ideal either.
There is this post which looks quite promising but is about the Xperia V (could that be adapted?)
And that is the first three pages of searching "xperia t 4.3 root unlocked"

[Q] Root, and recovery on Kitkat .757

Hi all,
I have a c6903 Z1 currently on Kitkat 4.4.2 (after an OTA update I really wish I'd never done) and I want to root it so I can install the SD card permission fix - can't put up with not being able to write to external SD, it's infuriating. If I can fix that, I can probably put up with KitKat.
If I'm still not happy with that then I want to go back to 4.3
Having read a lot, and I mean pages, and pages, about it, and having to downgrade, I've picked up that I would have to use NUT's .534 ftf to avoid losing the IMEI, and then I was going to root with vRoot.
Does anyone know, does that install Superuser or will I need the Superuser zip too?
At that point I want to then install recovery, so I'm looking at NUT's Z1 Locked Dual Recovery.
I rekon that should all be fine.
To get it back on KitKat I should then put the 757 zip on my SD card and flash in recovery, reboot and flash the stripped ftf with Flashtool, along with the recovery again.
If I still don't like it, I could then just repeat the above, but with the .136 zip and stripped ftf.
Am I thinking right here?
The only thing that's a bit worrying is that, for example, the .136 update thread says to come from .290.
Is this so, do I have to install that first, or can I go straight from the newly rooted .534 directly?
Sorry if this has been answered before, but my eyes are killing me staring at this screen now.
The only other thing I'm thinking is to just not root, and simply flash a Jelly Bean full ftf.
I'd rather have root and recovery though.
Thanks,
Mick.
wow, you didn't read much
DO NOT USE VROOT, IT SEND YOUR IMEI TO AN IP ADDRESS IN CHINA.
To get root on 757, just follow the step sin my signature
No need to use any root methods or unlock the bootloader
3 steps, 5 minutes work max.... a bit longer if you have slow download speeds

Thank you so much for your help, don't mean to be a pain, and I do appreciate it.

Will it make any difference if I use the Z1 locked recovery instead of the XZ one, or should I just use the XZ anyway? Does it matter?

download the file for the Z1 from [NUT]s page since that one is for this phone.
the XZ is for the xperia Z and that is a different phone. It is always advisable to download and flash things that are deigned/made for the phone you have, not another phone....
u don't need to install the 290 version first, get nut's 534 stock, then install dualrecovery and go straight with the 136 one.
Check nut's instructions or use this youtube video which is foolprove.

I am not sure if we got our wires crossed before.
the XZDR installer will install dual recovery on your phone from PC
the Z1 flashable file will upgrade to the latest version from recovery itself, but will only work on a Z1.

Oh, right, well, I've downloaded this installer -> Z1-lockeddualrecovery2.7.123-BETA from NUT's site.
I'll flash NUT's .534 ftf with flashtool first, then I'll run the installer from my lappy, and that should root and install the recovery.
I have also downloaded the Z1-lockeddualrecovery2.7.123-BETA.flashable - I assume that's what I need to flash after flashing another ROM if it doesn't include it's own recovery.
I have noticed some ROMS have earlier version recoveries, like .80, built in. Can I still flash the .123 on to of those with no issues? I have read there had been some issues with flashing over older recoveries.
Has anyone figured out why the IMEI was being lost? Was it due to the baseband
I've already got the drivers installed, in fact I successfully flashed back to .136 just to try it (last flashing I did was on my Arc S, so been a while) last night as I just couldn't be bothered with KitKat anymore.
Thanks again,
Mick.

If the installation was successfully then it doesn't matter. The older one working well. In the case you want flash the newets one then you have to wipe your phone with a stock FTF.

kind of, but don't worry, you will have your IMEI back after upgrade again.
I can open a topic for this question, but i'll just ask it here to prevent extra spam etc hehe.
If i get to a 757 rooted firmware using these methods, and i want to go to a non rooted firmware like 769 if it comes out. Will that be just a matter of reflasing the tft that belongs to that firmware using flashtool, or do i have to make more steps?

I can open a topic for this question, but i'll just ask it here to prevent extra spam etc hehe.
If i get to a 757 rooted firmware using these methods, and i want to go to a non rooted firmware like 769 if it comes out. Will that be just a matter of reflasing the tft that belongs to that firmware using flashtool, or do i have to make more steps?
Thanks for answering!

When 769 will be out then NUT will have Pre-Rooted FTF like the 757, so you will have just to repeat the same steps. If you will want go to 769 Stock then 1 step will be required, flash it via Flashtool.
I want to remind you also that we do not predict future so we don't know what Google will do to they future Firmwares so the steps can be less or more, nobody know it.
Just one more thing, sorry to be a pain.
I'm happy with the process, flash NUT's. 534 ftf, then run the recovery installer to get root and recovery.
I don't want to install a custom rom right now.
I either want to end up on 4.3 with root and recovery, or 4.4.2, root, recovery, and the SD card fix.
If I use the zip and stripped ftf files from NUT's download page, I'll still retain root access, is that right?
Then just reflash the recovery zip before rebooting, and job done?
I've had no issues with the stock .136 firmware I've currently downgraded to other than the NFC icon not appearing when active. Something I've gathered can be fixed by editing the build.prop, but doesn't bother me anyway.

Yes, that's why is called Pre-rooted.

No, the Recovery will still there from the first installation, it will not be wiped. After installing zip and strippied files, you will be able to boot into recovery.

Ok, thank you for your help, I understand now, just needed to be clear before I went ahead.
Better to ask than mess it up.
To get root on 757, just follow the step sin my signature
Where to find steps??
I really am getting confused with a lot of different info, please help with simple instructions.

Yes, I had the same problem, there's lots of info on here. There's hundreds of pages to read and it can get confusing.
I'll assume your phone hasn't been messed with. i.e. The bootloader is locked, and it's not rooted, and that you're using a Windows PC.
If you have changed your phone, let us know.
Make sure you have USB debugging turned on in your Developer Options, and Unknown sources in the Security settings.
To enable Developer Options in your settings, go to Settings, About phone, and keep taping Build number until it says 'You are now a Developer'
You'll need to download the latest version of Flashtool from here --> http://www.flashtool.net/download.php
You'll need to install the drivers for your phone too. The driver installer is in the flashtool/drivers folder.
Ok, so this is what I've gathered so far :
This is the link to the steps, thanks to gregbradley --> http://forum.xda-developers.com/showpost.php?p=52407809&postcount=2
If you follow those, you'll end up with a rooted phone with whatever stock based rom you fancy.
Now the following are my thoughts, and what I've learned so far, but I'm not an expert.
My advice would be read more, and make sure you feel comfortable with what you are going to do, before you do it.
If you are unsure about anything, ask.
You'll need to use Flashtool to flash your phone.
The second post here,from DoomLord, shows how to connect your phone in flash mode --> http://forum.xda-developers.com/showthread.php?t=2440565 - Basically turn the phone off, then press volume down and connect to the PC via USB when Flashtool tells you to.

I downloaded this file --> http://nut.xperia-files.com/?dlid=QzY5MDNfMTQuMS5HLjEuNTM0X1tOVVRdLmZ0Zi50b3JyZW50
You have to download that with your torrent program.
If you don't know how to do that, I've uploaded the ftf to my cloud storage.
You can direct download the .534 ftf here --> https://mega.co.nz/#!mgwkAagR!6_iTB3LwVkGz6yvSaKQsEVPtyaIPq3BJGFCk1EDw9XQ
Place the .534 ftf in the c:/flashtool/firmwares folder
Make sure your phone is fully charged, and back up anything you want keeping, as flashing will wipe your phone.
Now run Flashtool, click the Flash icon (top left) and select the .534 ftf.Flashing the .534 ftf that NUT provided will prevent loss of IMEI.
Don't mess with any settings, and click Flash, and follow the instructions on screen.
That will return your phone to stock 14.1.G.1.534

That should be it.
Unless your bootloader is unlocked, do not try to flash anything other than stock based roms as it won't work, and will brick your phone.
Hope that helps :good:

Bootloader is unlocked I have flashed firmware before but not rooted.
My main reason for wanting to root was to get rid of apps I dont want like the google ones.
Do you already have a recovery installed?
If not, installing the Z1 locked dual recovery will also root your phone. Just make sure USB debugging is turned on, plug your phone in normally, and click install.
As per my post above, I've just flashed NUT's .534 ftf, booted up, then ran the recovery installer, and it's working well.
I can boot into recovery, and have already done a nandroid backup. Best to do that before anything else.
All I have to do now is choose a rom and flash it.
In all honesty, if your bootloader is unlocked, I'd probably flash a custom kernel which has recovery and root already. I don't know much about flashing with unlocked bootloaders as I don't intend to unlock mine just yet.
Did you backup your TA partition before unlocking?

Xperia Z3- How Do I Downgrade to KitKat 23.0.A.2.98 So I can Get Root?

Could not downgrade to get root
Hi all,
I'm a very big fan of this community, but only to read and learn. But now I need your help...
History: rooted my phone few months ago in the way told in this post. Everything went well, but last week my screen broke. Sony fixed it but also put latest software on it... and removed root.
Today I tried to downgrade to KitKat 23.0.A.2.98 again (stil had the FTF) to get root again, so I can put back my Nandroid backup. I didn't manage to get it working... after restarting after flashing when the blue screen appears before you are asked to unlock your SIM... my phone makes a pitching noise for 10 seconds and then reboots again. The process repeats itself again and again.
Fortunately I can flash the latest firmware back and my phone works again... thank God because a thought for a moment I soft bricked my phone.
Anyone a solution to get root? I'm now on LP 5.1.1
thnx!!!!
ciao
Valentijm
How did you downgrade? The normal way... means: using flashtool (latest version) and which settings did you use for flashing? ...and did you try downloading a different version and flashing it?

Hi Tom, yes I did it the normal way... latest flashtool and settings the same as before, so I checked no boxes. After that didnýtwork I tried something different, so checked all wipe options. I also tried a different version and flashed that via the normal way. That didn't work either... the only flash that worked so far was 23.4.A.0.546 / R7C. But that's way to new to get root via downgrading
So the flashing process did always work without problems? But the result is always as you described?
And if it's only about root... did you try Kingroot? Afaik it is supposed to work on almost all versions.
Another thing: I don't remember all options by heart (and can't check them atm)... but maybe try some of the provided options.

It's more that when I reboot after having flashed back to earlier FW my phone bootloops... so I don't even get a chance to continue and root. Very annoying!
My next move is to find another old stock FTF (probably not a Dutch one) and will try to flash that one with different boxes checked.
When I'm back home I can check for the one that I used (quite recently) when relocking BL and rooting etc. If I don't find the source anymore, I can maybe upload it for you.
Ok... so this was the version that I used... to downgrade and root:
D5803_23.0.A.2.93_Generic_GLOBAL_1286-9917.ftf
try this link maybe:
https://mega.nz/#!f5pXVAIZ!nWmaFU9d5ux6FOUI6Kdv3GK8RObswoZzxRwpQVEvpxo
There's an easy way to get Root on 5.1.1 without having to downgrade back to kitkat
- Unlock your bootloader on Sony's Website
- Search for a custom kernel here that is for 5.1.1 ( e.g. Androplus, etc )
- Boot into fastboot mode in Flashtool and flash the kernel
- You now get recovery because the kernel comes with a custom recovery
- Flash SuperSu's latest Zip file to get root
- Enjoy

Maybe be careful when recommending that without mentioning, that he would loose his DRM keys in that process... so I would always add the comment, that he should have a backup before unlocking. Or at least mention the loss of the DRM keys as a warning.

Oops I almost forgot, but I always have my DRM Keys backed up

But it did not matter in the end anyway
