Dear all,
Just as you might already know, not all Xperia Z are blessed with having an unlocked bootloader .... it apparently is something related to the carrier though and not to Sony themselves. As it happens if your bootloader is locked and is NOT unlockable you can still head to the website and get your unlock code by putting in your IMEI.
Now that's weird ...... Now just wondering if the same procedure could be applied to get the device bootloader unlocked ....

Yes true but then again why does the Sony bootloader unlock site still provide an unlock code for locked bootloader xperia z's? This implies that the unlock code is used by Sony technicians to unlock bootloaders ... it's only a matter of determining what that procedure is .... This is definitely being used by carriers.
Really interested to know this for certain, I just got a Z on o2 UK and am a little disappointed that I can't flash any roms. I don't think I can live with stock for ever! Had previously purchased a (dreadful) bootloader locked xperia play which had the 'bootloader allow unlock' set to 'no' which a helpful guy on here managed to change to a 'yes' for the reasonable sum of £10 but this was using testpoint method which obviously won't work on a Z as it's sealed.
If the answer is definately a no to unlocking the bootloader even 'unofficially' then I think i'll have to send this phone back and try my luck with a different phone (an ugly S4 probably). I really do love this phone but I also love being able to change my roms as often as I like to whatever I like.
In the past a bounty would have attracted some devs to work out a cunning plan but if this is not possible at all then theres no point
Anyone know for sure?
Maybe if you change your customization and download a generic cust. ROM, you could probably unlock the bootloader?
If you backup you data and create an ftf for your current cust, you should be able to restore if it doesn't work.
Use the first guide to get an ftf of your stock ROM.
Second to check what generic customization you'd like to download.
Third to change your customization and download & get the appropriate ftf.
Flash the ftf using flashtool.

The unlock code is generated from the imei number I think, so putting in any imei number will return an unlock code.
Try it.

One guy claimed he done this but never came out with exact step by step instructions so no proof in this.
I previously tried every combination with no avail. as seen in previous threads about unlocking bootloaders we need alot of work done by a dev who knows what he is doing, sony have really tied up the security on these phones.

Well, it was a suggestion, you can try it if you want to.
If it doesn't work, then the only possible way is to somehow flash a bootloader that allows itself to be unlocked and this, I suppose, will require bypassing security.
The bootloader is usually not flashable and flashing an unsigned bootloader is even harder.
Reverse engineering bootloaders requires experience and involves a considerable amount of risk.
And that's only half the struggle. You also need to think about how you're going to flash it onto your phone.

I really would but I haggled a good deal with o2, £12 a month cheaper than what phones4u advertised with a free Z.
I am probably going to send it back though, just a shame as I really like this phone! Could always try phones4u and see if they will offer the same deal. I should have really thought about the possibility of permanently locked bootloader before I ordered it, after all the grief I had with my old xperia play.
So it definately can't be changed ever if it's set to disallow bootloader unlock?

So can no devs lend a hand to this issue. A lot of people with Xperia Z's are affected by this issue.
It's all down to the TA partition. If it contains "bootloader unlock allowed = no" then you are screwed. Trying to modify it or flash someone else's TA results in an unrecoverable, permanent HARDBRICK, regardless of what bootloader or kernel is flashed

I would like to point out something. Now I know these two things aren't the same, but I'd like to use it as an example. The Xperia Z's bootloader is locked, obviously lol, I've been modding xboxs and ps3s for a long time, and from that experience I think it can relate to this. Why? Well, from my experiance,on the xbox you can't put a custom dashboard unless you JTAG it, although you can get free games if you flash the chip on the disc drive but that's all. with saying that, it's like saying, you can put custom funcions in the Z but you can't change the ROM. So with the xbox, before you're allowed to flash a custom dashboard, you have to unlock your NAND software, with a ps3 (made by sony lol) you can flash a custom firmware if your on firmware 3.55 but if you're above that, you need an e3 flasher to flash your NOR or NAND chip to downgrade and mod it, one time with the ps3 there was a thing called a E3 Stick, I believe it was called that, i can't remember, and with the e3 stick it wpuld exploit the system cause it was a certain type of board it was build with... So if we'd be able to maybe, find a way to exploit the bootloader, or possibly JTAG it or flash it then I think we'd be able to achieve our goal of putting a custom ROM. The problem with the JTAG or flash theory is that we'd have to open the Xperia Z, so as another theory now, we find a device that we plug into the phone and exploits it to let us flash any ROM we want. just like samsung devices, if the phone gets hard bricked and it doesn't turn on anymore,fried, or if you want to reset the flash count you'd use a JIG to put it into download mode and flash any ROM you want to save the device.

No. The phone needs to be in fastboot mode to unlock the bootloader. The only way to send commands to the bootloader is via a PC.

I already hijacked another thread with this topic, since I consider it important enough for the wide open public, I created this thread and post the question in a more general way.
Unfortunately I didn't bookmark the page as I visited it yesterday evening, so I cant prove that I found this information, but take my word that I really did find the information as stated in the following lines:
In the process of reserching stuff for my brand new Xperia T I stumbeled upon a tutorial/how-to page which clearly and credibly stated, that unlocking the bootloader irreversibly breaks official updateability.
A little more detailed, what the page said: unlocking the bootloader a) breaks OTA updates, it also b) breaks updating the device via the companion software or c) the seus/sus tool. Once unlocked, one can of course flash official firmwares, has to get them through forums/linkpages/insider portals like xda-devs etc and flash them through the flashtool or fastboot. Relocking the bootloader does not restore the phone to a state where it can receive updates through "official" channels, one is forever bound to flashtool/fastboot.
Is this correct or not? Anybody with enough historical SE/Sony knowledge might even know, if it maybe used to be true for older devices and the mentioned guide possibly just copypasted the once correct but now defunct information for its Xperia T tutorial?
If you unlock via the official method you can not update again via official method. ATM, you can only unlock the xperia T via the official method

Thanks for clarifying. So the information I read was correct, the verdict today, at this time is: Bootloader unlock via Sony results in losing official update eligibility via Sony offered services and channels. Updating is always possible through third party tools of course.
Why this is bugging me is, as pointed out in the other thread: I have to phone for ~20h, I'm still deciding if I like it or not If I would decide to ditch it, it's resale value would be significantly lower, if the new - potentially tech un-saavy - owner won't be able to apply updates onto his phone.
On the note of unlocking: Do you or anyone have any idea, if community unlocking could be possible? And if so, what could be a reasonable ETA, based on earlier Sony/SE devices? Weeks? Months...? I'm asking because Asus tablets for example, won't ever be community unlockable, they hardcore alter stuff on the tablet using private encryption keys which only Asus have. Unless someone steals Asus' keys, which is highly unlikely, unlocking has to be done via Asus. I wonder if Sony is behaving differently on that front.
As far as I know new generation Sony devices can't be community unlocked.
However if you do unlock your bootloader there is a way in one of the other sections a guide to re lock it.
Sent from my Xperia T using Tapatalk 2
Partially correct.
I'm not sure if it still applies to the Xperia T, but with almost all other devices you can get back into the regular update cycle if you relock the bootloader (possible) and then flash a standard firmware with Flashtool. After that you can just use all the Sony tools again.
Yep as far as I know the above is right.
Sent from my Xperia T using Tapatalk 2
Then the verdict today would change into after unlocking one loses official update abilities until relocking the bootloader and reflashing the device to completely stock.
Damn I'm too scared to try myself

Does this mean that I can't root an Xperia T without breaking sony own update?
That's a :silly: bummber if it does.

No,
You can root no problems, Its just unlocking the bootloader that has issues.
Flash 7.0.A.1.303.ftf if you are not on it, then root using bin4ry method.
Did anyone actually unlock, relock and after that sucessfully update using either OTA or the Companion?
I can't try OTA myself. Although I'm on 7.0.A.1.303 I believe my device isn't completely free. It's optically/visually totally unbranded but a google search after my SI 1265-1624 revealed some russian site or so where I could spot the name of my provider in conjunction with the phones name. So I guess it's at least somehow provider tied (yet sim unlocked/sim free) as I also haven't got any update notification yet.
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.

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.

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.

Hi - my daughter was given the SP as a gift - it was SIM locked to a UK carrier because it was an (unwanted) upgrade. She got the unlock code and now is SIM free.
However, I noticed that the bootloader is locked (obviously) but also unlocking the bootloader is not possible (says NO).
I realise that Doomlord's rooting method works for locked bootloaders, but she is used to using CM. Whether CM or AOSP will appear for the SP or not is something only time will tell.
So, should I suggest she sells this and get something else, or will some exploit in the near future allow the bootloader to be "unlockable"?
I seem to remember krabappel2548 was looking in to something along those lines...
In general the only way to unlock bootloader is by using the official Sony ways by getting code from them but if it says bootloader not allowed then there will be no way possible.
On older phones you could unlock bootloader via text point method, this is not possible with the sp because when you take back off you can only see sim slot and SD card slot.
So if she is in a hurry then sell while phone is still new.

Well believe it, and wouldn't expect it to be anytime soon either.
It would be nice.
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%

No, just that Vodafone do not restrict the boot loader

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.

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.
