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!

Oh, are we demanding help now?
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
HELP!

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....

You just back it up as you would for a locked BL. Just remember to make sure you name them well so you know which is the locked one and the unlocked one.
NEVER use a TA backup from another phone, you WILL HARD BRICK IT

Hy!
I have an easy question. Some people have Branded SK17i, which says: Bootloader Unlock allowed: NO...
So, any chance to flash this without unlock Bootloader? I thinking in a method like Motorola phones (Defy, etc).
Any chance to work this?
Thanks a lot!
I think i fell upon someone who had the same issue. I think you have to debrand it first, then you will be able to unlock the bootloader using the Test Point method. Not entirely sure though.
What you can do is go through this thread http://forum.xda-developers.com/showthread.php?t=1285285
I am quite certain that there was a solution in that thread somewhere.
No way. In service menu i got: "Bootloader unlock allowed: No". I debranded it with Wotan (2.3.4 UK ROM), but i can't unlock bootloader.
I think it's not a problem, because a lot of Motorola has locked bootloader, and they have CFW.
We can root it, with zergRush, we only need a xRecovery or CWM Recovery port, and we got Highway to Hell
Interest thing: after S1tool Method in the i saw "r9xxx", not "R9xxx". In X10 Mini/Mini Pro it means the unlocked bootloader. So what?
If you checked the thread thoroughly you would have got your answer.
http://forum.xda-developers.com/showpost.php?p=18868348&postcount=103
Hope this clears the waters for you
Yep, I know this way, but I want to make an method, which don't need unlocked bootloader, like Motorola Phones.
Umm.... What? Motorola phones are hated because of their locked bootloader, resorting to a software solution to bypass the bootloader lock in order to get it to "fastboot" can only resort to problems.
Plus, ROMs in Motorola phones work way differently, you have to restore a cwm backup and then install the rom blah blah blah.
So its not easier in any way.
guys, here is the solution to unlock bootloader via testpoint method.
clear and easy to follow.
http://forum.xda-developers.com/showpost.php?p=18013064&postcount=44
this will help a lot of people if you succeed...
i do not understand why only some phones of the same model have bootloader unlock allowed:no
good luck

Hi there is it possible to relock the boot loader for xperia mini? I unlocked it because i tried CM7. Now I am thinking of going bag to original firmware. Any help is appreciated!
If relocating is not possible, what should one do to get as close as possible back to the original firmware, is it still possible to get official upgrades?
Best,

First, this is ray forum
Second, try here http://forum.xda-developers.com/showthread.php?t=1126358
Third, remember if you are doing it with official method, you will never able to receive FOTA or SEUS update, you can, but only by flashing from xda.
So since we did the unofficial method, After we update through SEUS the bootloader is still unlocked?
I don't know about that. Since the service info still says bootloader unlocking allowed, I think the phone thinks itself as still locked. Flashing from seus might rely more on drm instead of whether the bootloader as locked or not.

when service info says Bootloader unlock allowed: true, that means that it the bootloader is locked, but can be unlocked at will
as many devs say, unlocking the bootloader voids the warranty and bricks the phone when doing FOTA or SEUS
but there's a flashtool out there for us that will take care of it

You do know this method right? http://androidflip.com/unlock-xperia-phones-bootloader-without-losing-drm-data-track-id-working/ When using that method, it is unlocked but the report still says 'Bootloader unlock allowed: true'. So if you use this method (as what idareyou and me were doing back then) the phone thinks that it is still 'locked', even though it's unlocked.

Yeah. I can confirm that my bootloader is unlocked but it still says 'Bootloader unlock allowed:Yes'
I thought at first I wasn't succesful even though it went smoothly so I tried flashing custom Kernel and it was succesful.
I want to know if in the future if SE release their ICS and we update using SEUS the unlocked bootloader remains because believe me, I don't want to go through the same process again, I got electrecuted several time because I don't have test points, just a clip and copper wire.

Wow, that's a long guide. Is the main/only reason to unlock the bootloader to install custom roms (can't this be done with just root access?).
I have root, but don't really wish to install custom roms. I don't have the bootloader unlocked, but I know it can be unlocked
why to unlock bootloader?
why to unlock bootloader?
1. u can flash custom ROMs/Kernels
2. u dont need to worry if the new firmware can be rooted or not as with unlocked bootloader u can always ROOT ur device
3. Sony gives sneak-peaks/preview builds of latest OS which requires unlocked bootloaders, as they did with Xperia 2011/2012 line, so who knows may be Sony may give early builds of next android OS

I think it would be wise to mention not to forget to backup TA partition with DRM keys before bootloader unlock.
Thank you very much. This tutorial covered all the issues I ran into so I knew what to do.
Btw, the .bat for allowing unsigned drivers doesn't work on Windows 8. A quick google search helped me but maybe you might want to add that to your tutorial for other, less techy users.

if your bootloader can't be unlocked it means that you can root your device, but won't be able to install any custom firmware. But you can install XZDR recovery.
Once you get the bootloader unlocked what is the root method? Also, is there a different process for flashing roms?

to root device you don't have to unlock bootloader. Unlocking is for installing custom ROMs.
That I understand. Thank you. I was asking since i already unlocked the bootloader and am unrooted. What is the process to gain root at this point?

Use Flashtool. It can automatically unlock bootloader. Only unlock code 0xFBCD6A2B26CB8F88 is needed.
Cant figure out which file to replace and where it is. Can get my tab to recognize in adb devices mode but nothing is coming up when i type fastboot devices in adb. It is not recognized. I am stuck. Any help will be appreciated. I have got unlock code and the usb inf file but no light further.
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...
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

Do you happen to have a Nandroid backup that was made before your bootloader was unlocked?

I have the same issue.
I bought a used Z Ultra on line. I have no TA backup. On service menu=>configuration showed: "Rooting Status: Unlocked Bootloader: Yes". Had my phone's bootloader been unlocked? If yes, how do I re-lock it?

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'm not at a pc with flashtool on it at the moment, but if I remember correctly you can just do it with the padlock icon at the top left

On service menu=>configuration showed: "Rooting Status: Unlocked Bootloader: Yes". Does this message confirm my Z Ultra boolloader had been ulocked?

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.
In the interest of not opening another thread - say I had my TA partition. What would be the process of restoring the phone? Flash rom, flash TA, lock bootloader, reboot?

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

While the phone is rooted:
Use TA backup to restore TA, this should relock the bootloader
Flash Regional FTF for your model
