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

[HELP] "Invalid Sim - No Service" No Signal But on firmware .136 works fine

My phone doesn't seem to receive any signal when flashing any firmwares othewr than .136
I was on the Monx rom for about 4 months but felt like restoring the phone back and trying something different. So I flashed a generic UK .534 firmware I had on my pc with flashtool as I still want root.. But once it was completed I received the fatal "Invalid Sim - No Service". I tried the original o2 sim in the phone which my Xperia used to be on before I unlocked it but still got the same error with no signal. I flashed it a few more times but it didn't make a difference. I thought it must have been something wrong with the ftf of the generic one so i downloaded the .257 generic uk ftf as you're able to root that too BUT same "invalid sim" popped up again. I tried restarting a few times, different sim cards and nothing works. I then found an o2 branded .136 on my computer which I must have made as a back up...I flashed it and it worked fine again with fulkl signalk and no invalid sim message. I thought maybe my handset will only work with o2 firmwares since only that ftf worked...i decided to download a .534 o2 ftf since as I mentioned i need root but same issue again!
I'm so frustrated since the ftf that root doesn't work on is fine. I have no idea why this issue is occurring
Sorry for the long read. Any help appreciated

that always happens
just flash any 534 FTF
root it
install the rom of your choice
it will be fine

Then flash a pre rooted rom of your choice.
If choose to stay with 534 you will never get a signal.

[Q] Unable to downgrade to .534 after mainboard change!

I have rooted my Z1 many times without problem, first downgraded to .534, root with Bin4ry's root tool, then flash the .zip file from recovery and flash stripped .ftf with FlashTool.
By rooting this way I can keep my bootloader locked.
A couple of weeks ago I had to send my phone for repairs when the call speaker gave up and they changed the mainboard (new IMEI).
After this I can not downgrade to .534 anymore! It will stuck at a bootloop, with only the Sony logo showing. Downgrading to .257 (the version after .534) is no problem though.
I have tried many different .534 tft-files, including NUT's.
Any ideas? Could this new mainboard be incompatible with the oldest firmwares? Sounds unlikely to me.
Thanks!

If it's incompatible with 534 then i'd be surprised, my guess is that it's a dodgy download and you should re-download the FTF file or an alternative and make sure it's the only thing that your computer is doing at the time, even check the MD5 checksum if it's available.
Are you flashing the full FTF file when downgrading and allowing for a wipe?
Only problem i've had when downgrading is losing the IMEI but after you've rooted , installed a custom recovery and installed a custom rom that'll come back anyway.

It's not branded. No SIM-lock, Generic_NCB customization. C6903.

Which version of flashtool are you using currently? I've found that some firmwares just don't like the older flashtools.
What about different USB cables? Shouldn't make any difference but I thought I'd ask. I find it odd the way it'll work for newer but not older firmwares, perhaps someone else should chime in with an idea.
I'm all out, as this isn't something i've come across and everything i'd try myself i've told you.

DO NOT USE VROOT!!!!
It send your IMEI number to an IP address in china..

Well, I tried vroot because it is in the first posts in the "Ultimate Xperia Z1 Guide" sticky thread.
Since I have always used Bin4ry's tool, I guess I have not noticed any thread about vroot being dangerous.

Right now I have .257 firmware flashed which is a 4.2.2.
I have tried to root with Bin4ry, vroot, Kingo, and [NUT]s recovery, but it is not possible.
Everywhere I look people say that it is a must to downgrade to .534 when rooting with a locked bootloader.
What have I missed?
Thanks,

257 was the first one that closed that exploit, you have to go back further.
I know you say 534 does not flash for you, but what error does flashtool give?

Thank you, I misunderstood an thought .257 was rootable too.
No error in Flashtool, flashes fine but is stuck on bootloop with Sony logo.
Tried .518, .526 and .534

make sure you do not exclude any part of the FTF and wipe everything,
Can you get a log from the phone?
Make sure you backup and clean your sdcard (So there is no trace of recovery files on there)

I have cleaned the internal sdcard and tried without external sdcard and simcard.
Don't think it is possible to get a log file from the phone while in bootloop?
If my new mainboard is incompatible with .534 and older, I guess other users would have the same problem?

[Q] How do i get from vanilla to Xposed?

Hi everyone,
So i have an xperia z1 on 14.3.A.0.757. Vanilla, not rooted, havnt unlocked bootloader.
I would love to get Xposed Framework but i have been searching all over the interwebs but its so unclear.
Could someone explain to me EXACTLY what needs to be done to get from vanilla to xposed? And how i would go about doing this, the easiest way! Any links to good explanations and step by step guides which are safe would be much appreciated!
Thanks,

Not from a 757 firmware.
You can try excluding data when using flashtool, but I wouldn't do that.
However, if you can update to 4.4.4 via pccompanion you will not lose data and you can root that very easily without losing data using newroot

However, if you can update to 4.4.4 via pccompanion you will not lose data and you can root that very easily without losing data using newroot

wait so i am on 4.4.4 and updated to it via pccompanion, does that mean there is alternative root method which means no loss of data? I heard bout some towelroot thing, does that exist for the Xperia Z1?

Yes there is, what build number are you on, you said 757, but that's not 4.4.4
Please post what it says in the build number and android version from settings/about phone

4.4.2 (woops thought i was on 4.4.4....)
14.3.A.0.757

OK, you will probably lose data when rooting then.
Flash a FTF from the FTF mega collection that ends in .108 or .118
then use the newroot tool to root it

Because you cannot root 757 FW
Either downgrade to android 4.2 (i.e a firmware ending in .534) or upgrade to the latest android version 4.4.4 (ending in .108 or .118) and root it.
