i try this but still same not relocked

Relocking is not yet fully and flawlessly possible.
The current method for relocking worked for some, others posted myriads about how it screwed all up. As the level of technical proficiency of those users is unknown and not really determinable, at this time is probably safe to say, it's a) up to you to try and b) may work with a certain chance or c) it may not.

There is still a possibility that it does not work with your device (right now).
If you access the service menu and look up the "Bootloader unlocked" status it should either read "yes" (unsuccessful) or "unknown" (successful) if you have used the tool.
Also note that DRM keys are not coming back, so BE2 will still be missing after a relock.

[Q] bootloader not allowed xperia z

my phone is showing me that it cant unlock boot loader when i see in service test bt typing *#7378432#*#*
i am from india and using normal xperia z (not any docomo or any)
can any one say what to do for getting permission for unlocking boot loader

Short answer - you can't unlock it ever.
The only exception would be if the status changed to disallowed after rooting. There is a fix for that somewhere in Doomlord's rooting thread.

First time I checked, I was also disappointed, a few days later I realized that I checked the status without having a root phone. After I rooted the phone it said yes for me.

Maybe. Only if the bootloader was actually unlockable to begin with.

Short answer:
If your device says Bootloader Unlock Allowed: No, it means you CAN'T unlock your bootloader.

Unless it was rooted, as this sometimes changes the status to 'No' as stated in the first post of Doomlord's thread. I used bin4ry's tool and the bootloader status was untouched.
Edit:
DooMLoRD said:
if u had an unlockable bootloader device, after using this method the device will be detected as LOCKED or unlock not possible!!! (to fix this use this fix)
...........
Troubleshooting:
if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a repair via SEUS will flash back stock firmware and turn this status to "Bootloader unlock allowed: Yes" (the same might also be achieved by flashing a stock FTF using FlashTool )

Hello, everyone.
I know nothing about rooting, flashing or unlocking bootloader. What I really need is to unlock the network of my phone. It was bought in Portugal locked to the TMN network. I am now back to Brazil and want to use it here. The conventional method of unlocking network is buying a code, but I want to know if there's a way to do it with no expense. What do you guys recommend?

Hello and welcome to the forums.
The only way to network unlock this device is with a code, either from the original network provider or from an online seller. It is not possible to unlock any other way.
Additionally, as you're new here, I will suggest you should start a new thread when you have a question in future instead of bumping a very old thread unrelated to your question.

Hi, welcome to the forums.
This is the Xperia Z section. You should ask questions regarding the Xperia Z3 in the Xperia Z3 Q&A, Help & Troubleshooting forum.
Sent from my C6603

I'm thankful that there are still wanting to address this issue of the bootloader not being unlocked. So my question is as such - Is there anyway (either by contacting T-Mobile, or Sony) that my phone, which is is SIM Unlocked (I know SIM unlock has nothing to do with bootloader unlock), can be bootloader unlocked? I'm just hoping that I can either get with Sony/Tmobile and have them do it, or even if there is a legitimate paid service out there then I will do that too! Any kind of help or anything would be appreciated! All I read is, 'If you're bootloader says no than that means NO', or I will often see people say that their bootloader says no and yet they can still enter fastboot mode.
Currently my device is Sony Xperia Z C6606 Tmobile version. I'm going to try to switch out my microUSB cord and see if fastboot works then. I'm still trying to have some kind of hope that maybe it will somehow work and I can flash a custom rom. Currently, whenever I plug in my phone into any computer, (with drivers installed) it never even shows up in the Device manager so I'm thinking it's an issue with my cord. It charges the device only.
Or should I just sell this phone and get a different android phone where I can unlock the bootloader? lol
Thanks!

You can only flash stock based roms with a stock, unmodified kernel.
Fastboot will connect even with a locked bootloader, but the commands you can use are extremely limited and in your case you cannot do anything with it at all. Your USB cable is not the problem.
If you want to flash CM/PA/AOSP etc, then you'll have to buy a new device. The bootloader is non unlockable. Nobody has cracked the security yet and I don't think anyone is even working on it, to be honest.
Sony or T-Mobile will not unlock it.

Could this work on the T?

I came across this interesting post:
http://talk.sonymobile.com/thread/40526?start=70&tstart=0
So I decided to request an unlock key, sure enough I was sent one! But as this isn't a guide for the T I'm concerned as I heard bad things about the unlock tool on flashtool. Any thoughts?

Yes but my phone says "unlock allowed: no" so a normal guide won't work, however if an unlock key was provided I'm guessing it was unlockable from the factory then they disabled fastboot for three. So to even use the unlock key I need to change it back somehow, maybe I will try this

Fastboot issues,bootloader (un)locked?

So I've unlocked the bootloader on my xperia Z the official way. Entered the unlock key and it was successful.
However, if I try to write a recovery in fastboot I get the error : Remote: not allowed.
I have made sure I have the correct drivers and all but it still doesn't work. Even tried unlocking it again with a second unlock key.
How can I fix this?

bump, still no cure found

Any help would be appreciated

Try to boot in recovery does that work?

not only allowed or not
if you have locked bootloader it says it is allowed
if you have unlocked bootloader it says that your bootloader is unlocked
you can check your bootloader by this way , cause your error determines that u have lockbootloader

Use flashtool, click the blu option and you can properly unlock the bootloader.

Unlock bootloader without losing DRM keys
Hey guys
I have a similar problem. I want to flash DoomLord's custom kernel but the command is not allowed. I found out bootloader unlock allowed does not mean it is unlocked yet, so that is the problem why it is not allowed. However, I do want to backup my DRM keys first. Is this possible? My phone was rooted before I flashed 4.3, so it is not rooted anymore.
Oh I have a Xperia Z 4.3 c6603 flashed with the ftf supplied by doomlord.

u welcome!
just checked the screenshot says that BL unlock allowed: status YES which define that ur BL (bootloader) is not unlocked yet!
make sure u are using the appropriate tool that works for ur device after u get the BL code from Sony, then follow the instructions in Sony where u got the information about unlocking BL
first off... do not proceed with bl unlock until you backup your TA partition cuz u might brick ur phone after the unlock is done if something goes wrong!
is it's not really recommended... u can still root it with a locked bl and enjoy ROOT privileges... FYI, unlocking bl will erase DRM keys and might affect on ur TA partition too.... so keep in mind that Bravia Engine2 along with Track ID will stop working after unlocking ur BL

help me unlock my bootloader

Hey guys last days im started looking how unlock my c6602 and i cant find any way that work for me
I tried doomlord way and didnt worked what i did:
1-Got my bootloader key from sony
2-connected my phone in fastboot mode to my pc
3-opend command window in the place i installed fastboot drivers
4-typed: FASTBOOT.EXE -I 0X0FCE GETVAR VERSION then enter i got VERSION:0.5
5-typed:FASTBOOT.EXE -I 0X0FCE OEM UNLOCK 0X************
6-i got that error :invalit id (0x**************)
I checked the number many times and it was currect SO WHY???
I tried flashtool to unlock and i got that (failed remote: command did not success)
Is sevice menu says bootloader unlock allowed: yes
Is there any solution for that??
Running:4.3 stock %100
EDIT: today tried again in command window AND NOW EVERY TIME I THY THAT SAYS failed remote: command did not success)!!!!!:crying:

I said this to you when you asked in the bootloader unlock thread, but you didn't respond or acknowledge my reply.
The unlock key is case sensitive. Meaning that any letters that are upper case (capital letters) must be entered in upper case. So E must be entered as E, not e.
If you don't enter the unlock key exactly how they sent it to you, it will not work.
If it still won't work, maybe you entered your IMEI incorrectly when requesting the unlock key. Try requesting it again and double check the IMEI when you enter it into the form, as a key generated for the incorrect IMEI also will not work.

Anyway i bored of that unlocking story now im trying to get perooted rom

Well, you're definitely doing something wrong. Both Flashtool and fastboot work for unlocking the bootloader for everyone else.
From your screenshot in the bootloader unlock thread, you were entering the key with all lower case characters, which was probably wrong if you're now entering some upper case characters. Enter it EXACTLY how it is in the email.
Anyway, good luck flashing any rom without root. You'll need root to install a recovery.

Are you deliberately not reading what I'm telling you or something?
You'll need root to install a recovery to flash that rom. If you don't want to unlock your bootloader, you will need to downgrade to a 4.2.2 stock rom.
