Can not be rooted by any tool we know of.
You have to downgrade your firmware, root it, then upgrade to a "pre-rooted" firmware. You can find all the info you need in pre-rooted firmware thread and dualrecovery thread amongst a few others. I did it myself yesterday. Piece of cake.

You have to downgrade to Build 14.1.G.1.534.

Flash 534, root, install CWM or TWRP, then flash pre-rooted stock 257 firmware.

It's out there somewhere, but I don't remember where and I don't have time to find it. Use the search feature and do some reading and I'm sure you'll find it. Especially check the thread dedicated to 257 firmware

Flash "C6903 14.1.G.1.534 Generic DK 1276-1249_R5A" from http://forum.xda-developers.com/showthread.php?t=2469191
then root with kingo , then make supersu update & system app (2 restarts required)
then go to Sony update and update OTA.
You will have latest version 14.1.G.2.257 ( it is stock Euro - no bloat) with root.

use this method.
I have a question too. I have a C6902, can I flash C6903 into my device?

No, it might brick your phone.
My device is C6902, and now I'm using .257 firmware. If I using flashtool to flash .534 but not wipe data, does it cause brick my phone?

No, it will not brick your phone if you choose not to wipe data. But make sure you're flashing a C6902 534 firmware.

Hi guys! thanks for your time on reading this.
I have an Sony Xperia Z1 C6902 with 14.1.G.2.257 firmware. I bought it 2 weeks ago on USA (NY).
I saw that I got to downgrade and root, and then flash a new pre-rooted 2.257 firmware. I tried a lot of roots toolkit but obviously non of it works.
I´m a little scared about to flash a tft to downgrade an lose signal or something and can't go back to my actual firmware (because of no root, no rom backup )
SO, its better wait for a root toolkit for my actual version or try to downgrade?
thanks again for the time! hope you have a nice day guys

If you really need root then I say go for it. Just downgrade to .534 with flashtool, root it with root many android, then upgrade to .257 with OTA
You can always make your own FTF file yourself so you can flash it back. There is no danger in flashing them and you don't need root.

NO YOU WILL NOT
Read any of the several guides in the general section about how to achieve root on 257 FW
Not trying to thread-jack, but I was under that impression after reading guides saying you will need to re-root after flashing FW OTA 257.
Sorry for the ignorance....

Then you read them wrong, they all say that if you downgrade to 534, root then upgrade OTA you will keep root

Thanks for your quick reply!.
Sounds a little complicated but I will searchfor how to make my own ftf.
My problems is find a correct image to flash with flash tool. I'm a little scared to flashe the wrong one. I also didn't found how to make backup of my actual FTF without root, but again, I will search for it.
I want root first for install adaway, I used my old one x with it and now I cant stand for the ads... And I need 2 whatsapp ( one for work and one personal). Just need root for that.
thanks again. hope you have a good day
The answers to your questions are very easy to find if you Google them and /or look in the general section

Help a brother out
When the Z1 first launched, I was able to root the device.
I'm ignorant enough to not know if I had unlocked the bootloader.
General forum research tells me that if I'm not sure if I unlocked the bootloader, it means I didn't unlock the bootloader.
I updated my Z1 (C9606) to 14.1.G.2.257 Build.
I'm still running Android 4.2.2
Is there a way to root device without unlocking?
If so, could someone point towards the thread I need to follow?
thanks!

Hello,
flash back to .534 with flashtool then root and custom recovery your device and put a custom pre rootet rom on.I think that is the only solution also the same point as the threat starter asks for you only can use pre rootet roms for now.
best regards and wishes,
Nico

What if rolled back to .534, custom recovered, rooted and then tried to flash .290 (JB 4.3)?
Has anyone tried this?
Is there any way of getting stock 4.3 rooted?

I am running .290 atm and when I plug into PCC, says my newest firmware to update is.136. I want to skip. 136 because of all the bugs. Does this mean KK is not available for me yet?

Download FTF's from Development and use FlashTool to flash them, follow a tutorial if you want to preserve root

Are you sure. You seem a bit new to this, so I suggest using the files that are already uploaded in the development section rather than making one yourself
@[NUT] does have guide to (D)o (I)t (Y)ourself (Google NUTs DIY guide) but for new users I suggest just following the instructions in the OP until you have read some more
Hey pathanraj,
I rooted my Xperia Z1 today from 4.2.2 .257 to .757 .
Thanks to [NUT] that made it possible and easy, i suggest:
-Using his latest xzdr dual recovery found here
-Upgrading from .257 to android 4.3 .290 using his tutorial here
-Upgrading from .290 to android 4.4 .681 using his tutorial here
-And last, Upgrade from .681 to .757 using his tutorial here
So here is the procedure: Have root first of all, install recovery and then upgrade from .257 --> .290 --> .681 --> .757
You can do all this using the tuts from [NUT] , that i posted above.
Be sure to have a FULL root installed into system on your 4.2.2 JB .257
If you don't understand something, just ask for more info, It would be a pleasure to help a fellow member of xda-developers.com .
That is so much overkill
Flash 534 FW, install dual recovery, flash the latest prerooted rom. Done

Soooo true! as alway keep faith in gregbradley!
Just flash the .534fw , install XZDualRecovery, flash the .757fw by [NUT]
No need to flash every fw version between the 534 and the 757!

After I was refused a fix or replacement for this broken phone (mainly the touchscreen issue), I think it is time to root. Thank you, gregbradley, for providing useful information. These forums are helpful, unlike Sony themselves, retailers, or organizations for customer protection. Thank god at least somebody cares.
