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.

I'm on 14.1.G.2.257, wait or try to root?

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

You didn't do anything wrong, but currently Android 4.3 cant be rooted. if you want root, you have to flash 257 then 534 then root and OTA update to 257. and if you get OTA to the 290 android 4.3 you might keep root.

Do you know when root will be available for 4.3?
Sent from my C6903 using XDA Premium 4 mobile app

You can root, but you need to flash custom boot.img first. Just follow steps on http://forum.xda-developers.com/showthread.php?t=2573921

One of the 1st rules in XDA: Don't ask for ETAs
You must follow the threads and see, if one dev find a solution to root locked bootloader for 4.3. But take a look in the Xperia Z1 Android Development section. Or this thread, there a lot of hints and howtos for root.

Sorry I'm new! thanks for the tip!!

HOW TO ROOT.757 ftf

Kindly tell me procedure to root z1. 757 ftf...step by step

The same as the previous way.
Downgrade to .534, install dual recovery, flash SuperSU.zip, then flash a pre rooted .757 Rom.

I just updated from rooted 681 to 757 and stayed rooted

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!

You follow the instructions that are posted in the update to 757 thread in the development section.

But my apps, settings etc are away after flash, right? I prefer an update to save my phones settings and installed apps.

make a backup then... and restore it afterwards
But if you actually read the instructions and the thread (Instead of asking questions) you will see that you will keep all you apps and settings if you follow the instructions

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.

Find out what firmware version they're running then come back.
If you provide no information, then you cannot expect any help other than being told to search.

Kingo Android Root worked well for me until I updated to 4.3 Sent from my xperia z C6606 Sorry everyone, just thought I'd help the guy.

It isn't a matter of not wanting to help. He provided no useful information. The method of rooting varies by device and firmware version, so if he didn't provide that, then nobody can provide the correct information.
I don't recommend using Kingo. It collects a large amount of information on your device including hardware IDs and serials and sends them to a server in China, supposedly in order to download drivers. It does facilitate that, but just the model number could achieve the same. They even used to collect your IMEI until they were caught and stopped. Not exactly trustworthy behaviour.
If you're running 4.2.2 or older, use Root many Android by trusted XDA dev Bin4ry to root. It doesn't collect any info or even connect to the internet.

Here is a post I made in another thread regarding downgrading/rooting.
This may be helpful as well - How to flash stock roms with Flashtool
The images in that tutorial are broken, but the text explanation should help.
It is also possible to root then upgrade OTA and keep root, but it requires SuperSU Pro. If that's the route you want to take, then after downgrading, instead of flashing a recovery-
Root with Root many Android
Enable OTA survival mode in SuperSu Pro
Update via OTA
