You cannot root this firmware

If you have read the numerous threads before updating, you'll find out that the old methods no longer work as Sony closed the root exploit in the new update.
The "longer" way of rooting the 257 firmware can be found here:

What Android version do you have? What model number is your phone?

This thread is super old... Only .534 can be rooted, then you can OTA update to .257

Downgrade to .534, root and then upgrade OTA.
Download the file here: https://mega.co.nz/#!K1QD1bSK!JkgNvz3Tqb6lq4brVUEyZGraOjMQuTuzn8IaEFhQhUI (ftf file for .534 firmware)
Use flashtool to downgrade it ( untick wipe data/cache/appslogs )
Then root it with vroot or something else.
Then it will prompt you to download .257, doing do it OTA not through your PC

sony is telling me to update to .290 now, will it tell me to update to .257 after i downgraded to .534? or keep telling me update to .290?

It will tell you to update to 290.
However, if your bootloader is unlock-able, backup TA partition then unlock it, then install a recovery and flash Supersu flashable zip, then flash stock kernel and then restore TA partition.

by than 4.4 is out..

Gettin abit confused now with all this root, bootloader, 4.3 stuff.
am still on 257 (rooted), i have the 4.3 OTA notice but i know if i update ill lose root (maybe partial root). ive heard that 4.3 can be rooted but requires unlocking the bootloader. when i go into the service menu it says: Bootloader unlock allowed: NO.
does this mean its not possible for me to root 4.3 at the moment.
if not then whats the limitation on Partial root, i dont do anything particular advance with root, just get certian apps (greenify, ad-away, autohide softkeys) can these apps still function properly on Partial root?
sorry i know these questions have been asked elsewhere but its pain trying to look through the many many threads or looking through about 60 pages on 1 thread.

Bootloader unlock allowed: NO means you can't unlock bootloader.
Partial root doesn't allow you to edit anything in the /system or in the root /.
Anything that edits system won't work (Probably autohide softkeys probably won't work. But it might work if you installed it before updating).

so is the no hack to force bootloader to unlock?
sorry if some questions seem stupid. was an iOS person until i got the z1. use to think jailbreaking was a nightmare but its a blessing in comparison to rooting Android or more specifically the z1.

Yes, and the solution is simple, flash stock 534 and root it with kingo root or vroot or whatever way you may want to use. Then backup TA easily.

Downgraded now my IMEI has gone missing? Z1

Had a problem with recovery going missing when i updated to 4.3, decided to downgrade back to 4.2 rom 534 and after the downgrade my IMEI reads a series of 0's obviously can't make any phone calls and have no signal at all.
Have tried to get the EE branded ftf but it wouldn't download, I didn't want to get another branded one so i went with an unlocked one, still can't get the EE ftf so can't revert back to my official branded rom, still haven't got recovery and by using an ftf i've lost root, so i'm kind of back to square one but with no imei lol, ahhh if i didn't laugh i'd cry.
Any ideas how to get it back up and running?
Cheers.

This may help i havent tried it myself as thats one of the few problems that my crappy Z1 haven't got .

Only just got home but i've sorted it now, basically i wasn't able to get the EE branded ftf from XDA as the link was down so i got the tmobile one as it's pretty much the closest one there is in the list.
Flashed that with flash tool and it came back, obviously lost root, so i've re rooted and now i'm upgrading all over again.
Will be staying on 4.2 until i've got a whole day to mess about with things, 4.3 isn't for me yet, at least until root is 100%
Cheers for the help all the same.

Problems occur if 4.3 is flashed using flashtool.
I solved it by reinstalling the software using SUS then flashing 4.2

Just grab the closest rom you initially started with and flash with flashtool, that's pretty much all i did.
Then root.
Install clock work mod or TWRP.
Then flash a rom from the development section like monx.

I assume you didn't understand what I mean, while using android 4.3, flash for the previous firmware 257 (the unrootable android 4.2) and then flash 534 (the rootable android 4.2) then root and OTA to 257 again, then from 257, if you get OTA to 4.3 then go for it, if you don't have OTA to 4.3, you'll have to wait.

Just one leap back to the earliest rom is all thats needed to get your imei back, obviously not the easiest way but probably the safest.

If you flash from 290 to 534 you will loose IMEI and service provider signal, if you flash back 290 you will get them back. so to prevent loosing IMEI and service provider signal, flash 257 then 534.

Jeez i'll say again.
I downloaded the T-mobile FTF file as it was the closest to my EE phone when i got it, i was on 290 and without my IMEI, i flashed the FTF file via flashtool which is a 534FTF and my IMEI come back as soon as the phone came on, i was able to root and upgrade to monx's rom.
So what you're saying is untrue, if you pick the wrong FTF file then that may cause the IMEI to be lost again or not come back at all, but if you pick the one as i said before which corresponds with your phones original network or the closest thing to it then the imei will come back I know this as I did this a few days ago, i'm not going to argue about this and i'm not going to respond to anything else on this matter.
If theres another way to do it then fair enough, all I know is that doing it this way worked.

The imei gets lost if you wipe data when you are on 290 and flash 534 using flashtool

You don't need a TA Backup on 4.3 (.290) and applications like Kingo, Vroot etc. will only work for 4.2 (cant remember the number, i think it's .527)

You don't have to unlock your bootloader to root your phone. You will lose your warranty. At the moment you can't root directly the .290 with Vroot or 360 Apps.
To root your .290 phone you have to follow the instructions carefully form the link I give you.

If you decide that you WANT to Unlock your Bootloader. I have found a real easy way to go through the process of unlocking and then rooting straight after.
Give me a message if interested.
I too spent days/weeks following tutorials and could not get my head around it(Especially unlocking bootloader). in the end i found my own way...

As said by @Just2Cause you have 2 choices :
1- Downgrade from 290 to 257, then from 257 to 534 (then root then OTA to 257 if you downgraded to root it).
2- When downgrading from 290 to 534, exclude "Baseband" in Flashtool and you'll be good to go.

And why do that? He just can use the FTF .534 by NUT and downgrade directly to .534, then Root and follow the steps to upgrade to .290 and then to .136. Done.

i'm confusing with it i need to flash in order, i mean first .257 then 534 or i can do it directly to .534 excluding baseband.
other thing, only the baseband, idon't need to exclude TA.
