4.4 cannot unlock bootloader, Unlock Bootlader can be done from this site only here: http://unlockbootloader.sonymobile.com/instructions
Now, translate carefully and answar this questions:
Did you Backup TA?
Did you rooted .534?
Also you should have back the camera working after update to 4.4 FW .757, but I heard that someone lose the camera permanently after Unlocking Bootloader on .534.

without the TA backup if you unlock on 534 the camera is broken forever
Those that unlocked on 534 needed to restore the TA backup, upgrade then unlock to get the camera back.

Sony themselves said they fixed that with a firmware update, dunno exactly what firmware the fix came in but as i understood it was fixed so the camera will work from 4.3 and onwards. Because the camera will work with custom roms.
And well, everything is fixed that was said to be gone in firmwares after that, according to Sony. And yes you can relock your phone with flashtool. But DRM keys will gone forever, but then again as Sony says "it wont change anyhting with the phone, unless you put a custom rom in it with the firmware that is today". So DRM keys seems not that much needed anymore.
But it IS a good thing to always back up the TA and DRM keys before doing anyhting. I didnt do this and have never done though

[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....

oh.. I hope everything will still fine .. but I saw option in flashtool to relock BL.. it won't relock my phone ?? ... and what is the safe way to update my device firmware when 4.4 kitkat arrives to xperia z1 ??? and what are the risks now ?? what I must avoid and never do ?? any advices for me ???... sure it's better to stay one 4.3 without root rather than breaking my phone

Should be all fine but the safest way was backup TA first because if one day happen something on your phone you can't go via warranty.

You still losing your DRM keys so even if he does it's compromise, no x-reality, bionz engine and bravia.

This is not a problem, the FTFs will be upload here on XDA like for .290 and Custom Roms as well.

This is what we said already, the risk is if you brick the phone and the warranty will not cover that.

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?

[Q] TA and DRM keys ? Am I ready to Root ?

Quick questions and no they haven't been answered directly the way I am asking them :
1) If I wish to later do warranty repair and I currently have a locked boot-loader is backing up the TA going to give me a 1:1 undetectable root and later unroot if I choose. (i mean all my gracenote, bravia, and other DRM's be returnable to stock condition)? (if so which method is the BEST.. ? seen a couple now)
2) My stock firmware doesn't seem to be on the FTF list is this possible I have a : c6906 C6906 14.3.A.0.757 Generic CA R10 ??? This one is on the list I don't think so ? Perhaps I am reading the string from the wrong spot.. ! In which case anyone know what to do to make a backup ?
3)Everyone hates this question but I have to ask does anyone here know of a way to unlock a locked bootloader :YES flagged device; I feel like a dink asking but after sifting through hundreds of posts there seems to be contradiction as in some people eventually figure it out and/or have unlocked z1's which I have read elsewhere that every single z1 comes from factory with bootloader locked yes?
Answer one of these questions for me make my day and you will have my many thanks to come

1) Why Unlock Bootloader for Root if you can get Root on Locked Bootloader? First get Root on Locked Bootloader then Backup TA and do whatever you want. Best way is with the application to Backup TA, with that one you can Unlock and Relock, as you already had read 100 post then you know which method you have use to backup TA, right? (no? then search again) BTW, Yes, after Relock bootloader with the Backup of your TA your phone will be stock like new.
2) Perhaps you should understand that it do not matter, download any Generic CA or International CA for your specific model C6906. Done.
3)What that even supposed to mean? Type *#*#7378423#*#* and go to Configuration, if there is Bootloader Unlock Allowed: Yes, then you can unlock it, if there is NO, then is no way to Unlock it. To unlock it there is only ONE WAY, google it.

1) I think you may be confusing root and unlocking the bootloader. TA partition backups are for re-locking the bootloader, not removing root. In fact you must be rooted in order to make or restore a TA backup. Generally only an unlocked bootloader voids warranty, not root. Though if you're worried about it, you can always flash a stock FTF and you will be back to stock without root.
For TA backup there's a Windows app that will do it, just Google it. Works great
2) Your firmware is there. Google "c6906 14.3.a.0.757" and it's the first link
3) As @eclyptos said, if your service menu says unlock is allowed, then you can. If it says unlock is not allowed then you can't and I'd say there's a 99% chance you will never be able to.

almost fully clear on this but still curious how my device is R10 which I don't see on the 6906 list.. I see r4 and so on.
I have read on a website that unlike z1s and other z devices every single z1 comes from factory locked. If so then how come some people have proclaimed the unlock success? Maybe that was just misinformation?
Thanks again will properly thank everyone later at home currently using the app

Yes, it's your misinformation. All of them have Bootloader Locked from day 1, Z1S is Locked Permanently and Unlockable, Z1 is Locked but can be Unlocked from the Official Sony Web Page, just google it.

in which firmware u unlocked the bootloader and rooted the z1?
If you Unlocked your Bootloader when you was on JB 4.2.2 then you upgraded to KK 4.4.2 then that's the mistake...

help me out ?!
Something wrong here, i can confirm unlock bootloader on 4.4.2 can't stop camera function. (i unlocked my phone on kitkat firmware 757, all working fine)

Something wrong here too, it not come out of box with Kitkat, so I presume you was thinking you have it but you don't.
If you brought it used then different story, but the story of the phone we don't know.
So I don't know how to help here as Unlock Bootloader on 4.4 do NOT Breaking the camera functionality.

I bought it new from Sony with Kitkat on it in middle east -Dubai
The issue is being sorted via PM with me.
However, this is a synopsis.
The OP unlocked the bootloader on 4.4 - Camera works.
Then, instead of just flashing a custom kernel to gain root, the OP followed a guide for a locked bootloader to gain root. Once they downgraded to 4.2 the camera broke.
In order to fix this the solution is
1) Relock the bootloader (by restoring the TA partition if a TA backup was made, in this case not, or by using flashtool)
2) Use pccompanion to upgrade to latest FW
3) Re-unlock the bootloader by the official method (Or flashtool, if it was re-locked with flashtool)
4) Flash a stock based custom kernel
5) Install SuperSU from the play store.

I don't think so if you unlocked on 4.2
If you unlocked on 4.3+ it wont break anyway
try relocking the boot with flashtool, upgrading by pccompanion then unlocking again with flashtool

[Q] Rooting issues - 4.3, IMEI, not actually rooted etc....

Hi All
So firstly I should say I only have myself to blame. I'm quite a techy guy so I just assumed i'd be able to root my phone without any issues and pick it up as I go. What i've quickly found out is i'm in way over my head and i'm an absolute noob!
Any advice would be greatly appreciated from those guys out there that actually know what they are doing. I have read many forums but i'm still lost.
My story is as follows:
- I have a Z1 that was locked on stock firmware 4.4
- I read that it would be a good idea to unlock the bootloader so i did this
- I wanted to root my phone but from what I read I could see I would have to downgrade the firmware to 4.2. So this is what i did.
- By doing this I lost my IMEI number, got very worried i'd ruined my phone. I tried many things to restore it, there were a variety of different solutions online, none of them worked. I eventually flashed a 4.3 firmware i found on this forum which restored my IMEI.
- I then read through a few posts of people who had similar issues and advice was given to downgrade again (if i wanted to root) but this time exclude the baseband etc. I did this, but lost my IMEI again! the advice didn't work
- So I then went and updgraded again! to 4.3 to restore my IMEI and network access
- There doesn't seem to be a way to root on 4.3 so my phone isn't rooted, that's ok. But when i try to use my banking apps they don't work! they say my phone is rooted even though it isn't! I have checked with root checker
- Like an idiot, i didn't back up the phone when i first started doing all of this, i didn't really know what i was doing so I am now in a situation where i have the worst of both worlds. They are, i can either 1. downgrade the firmware to 4.2, root my phone but not have a valid IMEI and network access or 2. stay on 4.3, have a valid IMEI and not be rooted but certain apps think i'm rooted so i can't use them.
So all in all i've just messed things up and i'm in way over my head. I would really appreciate some advice
Thanks
Yes you are right.
Also, there is no issue with losing IMEI when downgrading, it happens to everyone, but it comes back when you upgrade.
Also, if you unlock the bootloader there is no need to downgrade, that is a locked bootloader method of rooting
You should root before unlocking the bootloader in order to backup the TA partition, but you are too late now...
Solution
1) Use flashtool to relock the bootloader
2) Use pccompanion to update to latest firmware
3) Unlock the bootloader again with flashtool
4) Flash a custom kernel for stock based ROMs
5) Install SuperSU from the play store.
DONE!

I don't think so, the unlocked bootloader method is very generic and there are hundreds (if not thousands) of guides and probably as many videos.

Hi Greg, can you give me a bit more advice please.
i'm just looking at the tutorial to relock by bootloader. It says "before u relock bootloader u have to be on pure stock kernel (flash only the kernel.sin using flashtool), else the device WILL NOT BOOT after relock"
The problem is i'm already flashed on to an FTF image that was on this site. From so by doing this am i going to brick my phone? i'm confused and i don't want to make things work so your advice would be apprecaited
thanks

So i find on some thread that i should unlock bootloader, and i followed instructions and unlocked it, but without making some backup or anything else. So i have seen that there is official update for sony and i want to get back to lock bootloader. But when i enter flashtool and enter "blu" i click on relock bootloader, and start phone type *#*#service#*#* it say that my bootloader is still unlocked. How should i get back to locked bootloader or make official update to 5.1. Please make it more clear becouse i am pretty noob for android development and rest.
