Too late to do it safely, as you used vroot, your IMEI number has already been sent to an unknown IP address in china.
You will be better off doing some reading first, especially the link in my signature

What supposed to mean "safely"? Downgrade to .534, Install DualRecovery and then Update to Pre-Rooted 4.4 using method by NUT from here: http://forum.xda-developers.com/showthread.php?t=2711982

What do you mean my imei has been sent to unknown ip in china? What will happen now?

Who knows, they may do nothing, they may use your IMEI number for nefarious means. Just goes to show the power of doing your research before using something from a website in china on your phone.
You are not the only one, lots of other people have done it as well
You may just as well go ahead and follow the correct instructions to root now

They will come at your Home, direct from China, and knock, knock to the door, usually they don't use the entryphone, they will ask for you and they will ask to let them see your phone, then they will tell you that the phone is confiscated because the one with the same IMEI was stolen in China. Then you will go back home, in your rom, crying and asking your-self why did you use VROOT!!!
ROFLMAO!

Bootloader unlock says no but o2 say I can still unlock my bootloader

My bootloader allowed lock says no but o2 on pay monthly say I can still unlock my bootloader. They took my imei number and are processing the lock and I have to wait for a email and this can take 7 working days to process. Has any one else done this? As I'm still in my 14 day peace of mind and might send back but they do say will be able to unlock my bootloader
Edit
Just had a email to unlock my phone to any network so just unlocked and it still says bootloader unlock allowed no
But they said I could, do I just try it?

No they don't, the code you have isn't for unlocking the bootloader, just the SIM.
Before even trying to unlock the BL, I'd suggest your TA partition just in case.
Mine also said no at first, but I was still able to unlock it.

Who did you get the phone from? Mine is from Three UK and resolutely does not let me unlock the bootloader. Did you use the Sony method? Which rom etc?

Hmm stock Rom unbranded, bought it in the Netherlands. Most people here that bought the same phone aren't able to unlock their BL, maybe I just got lucky. The trick that worked for me was simply rooting the phone.

I think you did just get lucky or you just got a sim free handset by the luck of the draw. Which root method did you use? Someone else posted that they tried a specific combo of roms and two tries to unlock before it worked but never fed back any more info so it is possible there is an exploit somewhere.

Used the one I attached, can't really remember the topic.
Need to have USB debugging on.
Cheers. And the exact process? Step by step. I know it is tedious but it may be the tiniest thing (eg when you detached the usb cable or whether the sd card was in) that holds the secret.

Give up chasing it, if it was at all possible then it would have been figured out by now.

I really don't remember, since I've unlocked my BL I just flash a zip to get root back.
I firmly believe in Xda being able to make the impossible, possible. And there are no flawless systems. However I get what you mean, and don't think anyone is going to push on it now. Xperia Z is still a great phone and here is hoping the upcoming Google Edition will give us with locked bl more choice.

Problem with recovery z1 Help please.

Ok so i've made a mistake, fortunately I can still use my phone but i'm in unfamiliar territory.
What I did was download the 4.3 Rom by RomAur, installed the rom and the recovery as per the instructions within the thread, then rebooted to flashmode and entered flashtool so I could flash the kernel and baseband from 290, but made the mistake of excluding kernel and baseband and flashing the only other option which was BOOTBUNDLE, and since then my recovery has been inaccessible.
I've reflashed the dual recovery but it won't allow me to access it via the power on up or down method or the adb reboot recovery method.
I really can't continue with this phone or flash anything without a working recovery, does anyone have any idea how to get my recovery back please??
Any help would be appreciated.
I'm also wanting to unlock the bootloader but without a working recovery i'm a little hesitant to begin.
Phone: Sony Z1 C6903
Rom: RomAur v4.0
Bootloader status: Locked
Flash the kernel and baseband from 290 in flashtool then.

Well i've gone and downgraded but used an unbranded ftf, which has now taken over my IMEI, which now reads 0000000000000000.
In a bad way here and stuck in work with limited internet, i'm now back on a 534 rom and feel like smashing this thing up.
Going home soon so will sit down and go through it all again from scratch, wish i'd just left it on my old monx rom now.
Bad times.
Any other ideas Greg ? Or anyone else?
just upgrade back, I believe you get your IMEI back that way..
The problem you are having is that you need unlocked boot to get a properly working recovery and root on 4.3

Ah i see, well i'm downloading an ftf which is t-mobile 534, it's the closest thing i could get to EE, as at the moment i have no recovery and no root.
So should i do this in this order.
get this tmobile 534 and re root and get recovery, i imagine at this point my IMEI will still be missing (hopefully not) then what would you do?
Update to 4.3 by using one of those roms? and then unlock the bootloader? As thats where I ended up losing recovery, i'm thinking thats maybe down to me flashing boot bundle instead of kernel and baseband through flash tool.
Also doesn't unlocking the bootloader require system rw access?
And thanks by the way Greg, i appreciate your help.
Same thing happened to me. So I flashed Nordic 4.3 kept my data booted then flashed the kernel that comes with twrp. So far everything is great

1) Update to 4.3 using a FTF of your choice.
2) Unlock bootloader (This will wipe system and internal memory so have a backup of internal sdcard)
3) Flash any of the three kernels from the top of this post, I am using the third one with philz recovery.
4) enter recovery and flash the SuperSU.zip found in that same post.
Done.
You do not need root to unlock bootloader. The kernels have the recovery incorporated into them

How do you flash a rom without a recovery though? sideload? Not sure, but nevermind, i ended up doing what i said i was going to do and now i'm back online and have re rooted but still on 4.2, will probably stay on 4.2 until 4.3 is 100%
Not being able to use things was too much of a pain in the arse.
Cheers by the way m8

Ahh that sounds simple enough, cheers m8, well i'll maybe give that a whirl as i'm at home and obviously my internal has been wiped anyway, got a back up in work so i'm running on minimum until i go back there.
While i'm in this state i may as well give it a go.
Cheers Greg, will let you know here if it worked out.

Well i've not attempted the unlock because after following the instructions it says in my phone that my bootloader cannot be unlocked.
I downloaded a vodafone UK ftf if that makes any difference, i got my phone from EE.
I noticed that you said to someone that they couldn't unlock the bootloader if it said that? Is there no way around it?

Is there any solid data on how/why some Z1s cannot be bootloader unlocked? I have a C6906 from Overseas Electronics which I think was sourced from Canda and cannot be BL unlocked, though it's sim unlocked and otherwise works fine on AT&T LTE.
I found a thread/post here mentioning that Sony may be able to "fix" these devices (and possibly for free, at that). I'm going to run down that angle, but if there's any technical data on what could be preventing the BL unlock I'd be very interested in doing some legwork on my own.

Not too sure mate, think its coded not to be unlockable, in which case someone would have to do quite a bit of digging to undo whatever was done. And seeing as that the vast majority of people knew to buy from a source that doesn't have the NO to unlocking the BL I would say that its not going to happen any time soon. I usually do a bit of digging before I buy a phone, rushed into this one and I'm paying for it now.
I'll check out that link you put up, maybe there's hope yet.
Edit: as for the link you put up, that's just for the sim lock.
If you want an unlockable phone then you'll either have to claim from a 3rd party insurer an hope that they give you an unlocked phone or contact Sony for an RMA and hope that they give you one. Otherwise I can't see it.
But in all fairness your missing custom kernels and aosp type ROMs. Most everything else will work fine, including all (well most) the ROMs that are in the android development section, so that's not a total loss by any means.
When roots fixed completely for 4.3, well see more.

[Q] How to backup TA, MAC and IMEI with unlocked BL?

Greetings to everyone
I have already unlocked BL & rooted my 4.3 xperia Z1 with CWM recovery installed... the camera and everything works fine
So, how to backup TA, MAC and IMEI with unlocked BL? I want to avoid any furthur losing possibility of them
Sorry If this a repeated question but I have searched a lot before posting this
thank you
You can't Backup your TA if you Unlocked your Bootloader. You lost your DRM keys permanently. You will not be able to re-lock you bootloader and you are not covered by your warranty. Sorry but you should read carefully before do anything.
Yeah, too late, you should have done this before the unlock....

You don't have to avoid anything just read carefully everything when you try to do something. My advice is now to wait for the confirmed and safe way to root or update. In your position you already lost the safest way so I will root, update or flash custom roms to enjoy the phone but remember, it's your own risk and responsability.
Ive done the same, came from HTC.....so I will still have all tge features unless I flash say cm11 and try to go back to a Sony based rom?

You can't root this version directly.
You have 2 options.

2) Downgrade to 4.2, root via vroot then upgrade.

You can always use nut method for upgrade but it doesn't support this version i guess.

-done! rooted!
@chunlianghere, @thalada, What are you doing People? From all the links just one is correct, for .290. Also NEVER give advice to Unlock Bootlader because users cannot be aware of the risk doing this like lose Permanently DRM Keys and Warranty, FOREVER. Because if you do not advice of the risk someone can Unlock the Bootloader then lose DRM keys and if so it will NEVER be relocked and warranty will be void permanently, so before give advice learn what is all about!
@SpawnCube, the .136 cannot be rooted directly but can be Rooted with the method by NUT for Locked Bootloader. If your Model is C6903 you can downgrade directly to .534 with FW provided by NUT to not lose IMEI, then Root with Bin4ry, then Update to .290 with the instructions given HERE, when you have .290 rooted you are ready to update to .136 with the same method HERE.
For different Models the downgrade have to be done differently, downgrade to .257 FW First, then to .534 FW to not lose IMEI, but you will update anyway so there is no problem even if you will lose it.
Watch the Video Tutorial How To in the first Link for .290. It will explain all.

That sound like you try to be smart without know anything about it. So then you should go back to read the whole Xperia section before Post.
If you Unlock Bootloader you will lose DRM Key permanently and you warranty will be void forever. To avoid that You have to Backup TA, to Backup TA you need Root, but if you Unlock Bootloader before have root you will lose DRM. It is clear NOW?
I think only Samsung lose IMEI? Read again the whole Xperia section and Rooting Section.
If you love Samsung because is not so complicated then you are in wrong section.

actually i dont care much about DRM key anyway. send for warranty only if hardware is spoilt. the most ask them do last warranty repair.
if DRM key n warranty is so much important, than sony would hav "Bootloader unlocked: NO" for all phone in the world
actually sony doesnt do the warranty n repair. it depends on the company in tat particular country. like example for doomlord, his one is only flap damage, but can get 1 to 1 exchange. tat shows tat how good the company is in tat country.
unlocking bootloader n rooting is pretty much standard.
technology n software is improving at a fast rate. the most i get a latest newer phone.

Ok, here you are right but you have to understand that, what is not important you, it may be important for others, especially when we talking about Warranty.
We are here to give advice, then we should do this in the right way and inform users of any risk.

Install TWRP on my device (can’t be used, root needed), can’t create a backup *step 5 failed*
XZDualRecovery Question : I’ve download it, connect my device to PC then enable USB debugging mode. Execute the install.bat from XZDualRecovery and choose number 2. Does anything really happened? *step 6 failed?*
Then I install the flashmode and fastboot drivers from flashtool folders. Tried to flashmode C6903_14.2.A.0.290 Brand Generic NCB but it stopped halfway.

The Video Tutorial on that thread explain very well what you should do, did you watched it?
You have to downgrade via Flashtool to .534 FW provided by NUT to not lose IMEI, Root the Firmware with Bin4ry, when you are rooted instal Dual Recovery, then follow the instruction to update directly to .136 from HERE.
All the files you find in .290 thread, Post #3, Watch the Video, then follow .136 thread.

Unlocking bootloader allowed, why not root?

If sony is completely fine with us unlocking hte bootloader, as shown here: http://unlockbootloader.sonymobile.com/unlocking-boot-loader
Why did they make it so difficult to root the device?

If you can unlock the bootloader it is a very easy 2 second job to root.
But id have to downgrade my firmware. And my data would be erased. Seems so needless

That's only to back up TA upgrading with root from 4.2.2 is to 4.3 or 4.4 is not supported.
Upgrade to stock then unlock
Also I think losing all data is a sacrifice worth it besidesvyou can back up data Sony provides you with the tools or just copy SD card to desktop and restore when done.
OOORRRRRRRR.....
You can get pre-rooted firmware here http://forum.xda-developers.com/showthread.php?t=2711982
Backup TA and unlock(if you want but I'm getting the sense that you just want root)
The last option is the preferred one no downgrade pain nonsense.
And finally to answer your Question: Sony is gonna Sony they say they don't mind you unlocking boot loader but the remove the good stuff like BIONZ. Now just imagine with root in which they never claimed to not mind about.
yup owns Z1 and stuff.

As for unlocking bootloader there's no hope. But you can still get root by flashing pre-rooted firmware in the link I provided in previous post. Just follow the locked bootloader instructions.
yup owns Z1 and stuff. Also if I've helped you don't forget to hit THANKS - actions speak louder that words.
I did not thought that the first question of the OP was to root the phone ....
