Well I've searched 9 different times and this has not come up, although surely this hadn't been agreed before so I'm probably using the wing keywords:
I want to take my phone to the '3' site for a warranty repair. I need to unroot my phone, but I've been reading on here things about TA partition, DRM, warranty codes, locking boot loader back to stock, and some 'magic number' that needs to be resest to zero. the 'unroot' guides I have read do not touch on these.
I have no TA backup, magic number or anything else, just a rooted unlocked phone flashed with GPE 4.4
Anyone have a link to the definitive guide please
Thanks

You can lock it with flashtool, but you wont have the DRM keys if they check
@blueether. Thank you for quick reply.
So my phone's bootloader had been unlocked, right? How to check to see if some features of the TA still in the phone? I still see x-Reality for mobile available under Display menu.

In flashtool I see a file X-10_V1_BLRlock. Can I use this file to re-lock my Z Ultra's bootloader?

I would say yes it is unlocked, mine says same and it is unlocked. If yours were still locked it would say "allowed " rather than "yes" for bootloader unlock.

this does not mean ur bootloader is UNLOCKED! it means you can unlock the bootloader of your phone, if it says no, that means
you cant unlock it. to make the story short, u still need to perform the unlocking procedure of your phone.
if you didnt do that, u are safe because ur bootloader is still locked!
i was once a victim of this all i thought my bootloader is unlocked since the configuration showed "yes"
I flash a custom rom and boom my phone is DEAD!!!

This is not correct, if it says "allowed :yes" or "allowed :no" it is locked. If it says "yes" without including allowed it is unlocked.

Restoring the TA backup should relock the bootloader in the process, sorry that is about all I can contribute.

yes you can root with a locked bootloader.
to unlock your bootloader you need to have root access.
You can always backup your TA partition, and then unlock bootloader, and then restore the TA partition and restore bootlock as well.

hey thank you sir for the response. I got my phone with .257 version already on it tho, and from what I'm reading, I can't find a way to root on .257 without unlocking the boot loader. is this correct?
as I see it, the only option I have on .257 is to unlock the bootloader with the Sony method, but no way to root first. am I mistaken? thanks!

What you could do is use flash tool to go back to another firmware, then root, and then update to the newest version. But not flashing the kernel. then you can flash the modified kernel with CWM, and then flash the new kernel afterwards.
I think there is a tutorial on here that tells you how to do it.

ah yes, OK, that's what I was wondering, whether it is possible to downgrade the firmware with a locked boot loader, using Flashtool. perhaps I will try.. thanks
I just remember on some other devices I've had, a locked boot loader wouldn't allow a firmware downgrade.
Hello everyone.
I had posted this in the Z forum, not realizing there was a Z Ultra forum. So I will just quote my previous post and add some info at the end:
Hello guys. New guy here with an Xperia Z Ultra phone.
I'm trying to load the Paranoid Android custom ROM.
Had a couple of questions:
1. I went thru Sony's instructions to unlock the bootloader. When I ran the fastboot -i 0x0fce oem unlock (e-mail code), the first error message I got was "FAILED - Remote - Command did not succeed". So I tried the exact command again, and then I got "FAILED - Remote: The device is already rooted".
I have searched high and low, and cannot seem to find any way to verify that the bootloader is now in fact unlocked.
2. Reading the instruction on how to install CWM/TWRP recovery menus, Every single list of instructions includes the following "This tutorial is only for Sony Xperia Z Ultra with 510 and 493 LTE firmware. Do not use it for any other carriers or variants"
Again, I have searched high and low to find a way to confirm what firmware version I have. All I know is I have the C6806 model, with the build number: 14.2.A.0.290
So can someone please help out a very confused guy here? I don't want to brick my phone by accident
So far it's still working ok

So far, after doing some major searching, I seem to have found that I currently have "290" Firmware, and that this Firmware is currently NOT able to be rooted. Is this correct?
Also, I still have not found a way to verify wether the boot loader actually did unlock or not. From what I have been able to read, it seems that if a proper boot loader was in fact, unlocked, it would have wiped all the data on my phone along with the SD card data.
So far, it seems everything on my phone is intact. So does this mean the boot loader unlock command failed for me? If so, why did I get the reply "this device is already rooted?"
I can't believe how difficult it is to root a damn Android phone! Jailbreaking an Apple device is 10 times easier!
First of all, it's usually pretty easy to root Android devices. In most cases it's only a simple click, but sony has done a good(?) job at fixing exploits, so it does it much harder for us.
Second, you can check if your bootloader is locked or unlocked by opening the dialer and insert *#*#7378423#*#*, go to "Service Info" and then "Configuration". If your bootloader is unlocked, it should say "Rooting status: Bootloader unlocked: Yes". It's easier to use Flashtool to unlock the bootloader if you're having issues using a terminal.
You'll find the rest here (including bootloader unlocking). If you need some help, ask in that thread.
If you aren't boot loader unlocked then "BACKUP TA PARTITION" from My Lord's guide @LordManhattan
Just incase you need to re-lock it for service

First of all it' pretty damn complicated and unrewarding to root a Sony device. Not all android but Sony definately. We checked, bootloader is unlockable. We unlocked and relocked bootloader prevoiusly because there is no robust, easy-to-install ROM for ZU. But time to time we try to root it.
Now, the question is the same: what should we do to re-unlock the bootloader if anything is OK, but flashtool says "Command did not succeed" for the first time and "Device is already rooted" for subsequent times at unlocking?
Please write some advice about the question, not about TA backup and your success. Thx!

Bootloader unlocking is a straight forward process. I've had a couple of strange errors in Flashtool while trying to unlock the bootloader, but just close Flashtool and try again. Also be sure to be on the latest version of Flashtool.

No sir, not at all. I wrote please, no demanding. Well yes, I'm a bit picky because there were no answer and I usually find some on XDA. Besides I used custom roms on Samsung devices for years (SGS2, SGN, SGN2) and I was disapponted when I bought my XZU that there are very few roms and I couldn't use them (I managed with very hard work to go back to stock in 9 hours after unsuccesful flashing).
So there is some basic problem every time. Like trying to root but cannot re-unlock because of some mysterious errors with no solutions.
Enough of my problems, your answer is much appreciated, will try to re-unlock some time. Thx!

Oh, i get that. I came from Samsung myself, and this is my first Sony device ever, so I've had some issues myself. I've gotten the same error message(s) as you before, and i think i restarted Flashtool and rebooted my Ultra and it was back to normal again - i think, but it "fixed itself" after trying a couple of times, so don't give up. It's also important to always be on the latest version of Flashtool.
It would also help us if you could tell us what you're trying to achieve, so you don't end up spending 9 hours on something that takes 5 minutes
@Champdor
From what I can make out you have never managed root your phone or back up the TA. If the latter is true then there is very little point in relocking the bootloader.
Yes the process is a little harder than Samsung, but the last device I rooted was a ZTE, and that was even harder to root and flash from what I can remember (yes this is my first Sony device as well, and I will buy another...)
Take you time and read the stickies that we have written and all should go well. Don't be afraid to ask (intelligent) questions if you get stuck, and read some more

I have not had this error so have not tested this, but what happens if you flash a full FTF and wipe everything then try to unlock the BL?
And remember that you can take a backup of the unlocked BL (re member to name it as such) and just flash that to unlock again. Doing it this way you don't get the format that happens when using the unlock code.
I followed this post to downgrade, root, i use Backup TA v9.10 to backup DRM Keys, use Flashtool 0.9.14.0 to unlock Bootloader, then to flash other Rom's (stock and customs), came back to Stock Rom .681, relock the Bootloader with Flastool 0.9.15.0 flashed the last .757 and unlock the Bootloader again with no kind of problems using Flashtool 0.9.15.0....

Hello , i want to root my phone z ultra 6833 .757 i watch this video youtube . com/watch?v=uFSeSe8gQOY
i unlock bootloader after this install 757.img by flashtool so i can open recovery but after this i didnt find the same file he run i try run supersu.zip but the phone havent rooted plz what the problem
I have a new xperia z ultra c6806
Read a lot but still confused. ( Not everybody is made equal )
I want to root and back up TA
1 - My understanding is for backing up TA, i need to be rooted. But for rooting I need to be unlocked. But unlocking will erase the TA information. Am I wrong.
2- If I unlock boatloader can I flash back to pure stock for either warranty or returning the device.
Thanks
C6806 eh?
- Open the dialer and dial *#*#7378423#*#*
- Go to Service Info -> Configuration and check what is says under "Rooting status". Does it say Yes or No?
If it says yes, go ahead and downgrade to 532 and root it using Bin4ry's root tool, backup your TA partition and then unlock the bootloader, update to 757 again and flash Jackie's kernel and flash SuperSU. You can find links and what not here.

One thing; don't panic when you're noticing that you're not getting any signal at all (cell, WiFi etc.). That's the way it is when you're downgrading the baseband past .290, but you're only going to be on 532 for a short period of time, so it's no big deal. You'll get your signal back once you're back on 757.

So you figured out that you had to use Flashtool? You backed up TA? And you managed to unlock the bootloader and root?
Don't worry, this is a one time thing. The boring stuff is the downgrading and backup of TA, so since you've backed it up, it's done. If you have to relock your bootloader and un-root for whatever reason and you want to root again, you don't have to do this again. You then have to unlock the bootloader and simply flash a kernel.

My issue was downgrading and some driver issues with windows 8. All went well..
However now when I reboot I get this error " System UID's are inconsistent, you need to wipe your data partition or your device will be unstable"
But fixed that using twrp
I cant believe how good quality the phone hardware is.. Was using samsung for the last few years...
I am waiting for the next generation of z ultra and going to get that too.... Wish they introduce qi charging...
I have unlocked the bootloader and now i found that there are ways to root to root phone without unlocking the bootloader is it possible to relock the bootloader without losing any phone capabilities.
If you've already unlocked there's absolutely no point in relocking it, you get more freedom and benefit more from an unlocked bootloader eg custom kernels and roms
i just want to know what is the way and suppose i want to give them for warranty repair so i should be prepared lol

If you used TA backup after rooting and BEFORE unlocking, you can return the phone to a fully LOCKED state as if you had never unlocked it.
If you didn't do a TA backup, you can only relock it and thus the reseller/repair centre know what you did.
i never made any TA backup it wasn't available that time there was no root that time without unlocking it.

when i unlock it again, i get camera working...
is there any way to relock bootloader and make camera work like when device is unlocked?
(sorry for bad english)

Don't know how to fix it but you could just flash this kernel:
http://forum.xda-developers.com/xperia-x/development/root-xperia-x-34-0-2-292-modified-t3449708
All functions like x-reality will work with this kernel
Relock then FLash? hmmm

Thank for Reply,
so you mean i have to relock bootloader then flash that kernel then unroot with super su?
can i get relocked boot loader and everything OK that way?
but for flashing that kernel i have to unlock boot loader
maybe this works? :
i unlock bootloader then flash kernel then unroot and then relock bootloader
but that way android ask me for patttern at srart which i dont know what is it so i have to draw wrong pattern 30 times to get device factory reset.
i dont know after than kernel will stay there or not.
its like 1 week im working on this device day and night

No just keep you bootloader unlocked and flash that kernel, you´ll have all functions(like x-reality) and root

Problably not, you've unlocked your bootloader so your TA-partition is whiped meaning you lost your DRM keys. You can not get them back anymore. So without a kernel with DRM-fix you wont get functions like x-reality back. So just keep your bootloader unlocked and use a custom kernel with DRM-fix and you'll be fine.

Got a question, hope you can help me.
How close is that DRM-fix to the original DRM keys in terms of quality?

same quality
Is it possible to make the "bootloader is unlocked" message when booting up disappear?
No, only by relocking your bootloader.

Isn't Xperia XA came out on Android 6.01 ? if that so then you can use DirtyCow script to extract drm keys / TA.img.

you can block the bootlader now in android 8 and the camera is work
Hello: Someone can tell me if after opening it, the booloader can be blocked again. I have the DRM keys. I tried to do it by Flash Tool, but when I turn on the phone it always asks me for the android key and I do not know what it is.
Thank you.
I answer: Easy with oreo. An ftf of oreo is installed by flashtool and the mobile starts, we accept debug usb and developer mode. The mobile is turned off and reconnected to flashtool, given to the blu and relock option. When finished, disconnect the mobile and turn it on. Ask for Android key, well, it turns off and connects to xperia companion. The repair firmware option is given and the instructions are followed and when finished we have repaired oreo and the bootloader as before unlocking it.
Kisses, applause and thanks to all those who have helped me with the comments.
