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.

How kan i install recovery or cwm with bootloader locked.
My statu for unlocked bootloader is : no
Do You have one way to install this please
Sent from my LT30p using xda app-developers app
I don't think there is currently a way to do that. If you were to flash an unbranded firmware onto the phone would that allow you to unlock the bootloader (allowing installation of CWM)? I can't unlock my bootloader due to my PC being broken.

I'm waiting for a solution as well. it should not be that hard as they have a solution for the xperia s with a locked bootloader.
maybe some very wise and helpful dev can port cwm for us xperia t owners with locked bootloaders.

Flashing unbranded firmware will not allow you to unlock the bootloader if you currently cannot unlock it.
Well, no promises of any kind, but there is that one user which claims that after updating to 3.195 the bootloader status changed from non-unlockable to unlockable.
I have to stress out, I cannot confirm nor explain this and I do not propose that anybody tries this.
But we all know where this is going, right...? Sic...

Its safe to try, as long as you have a .ftf made from your original rom or are prepared to flash one the .303 .ftf's found in the all in one thread
I've flash one week later the 3.195 and my statue dont change.

You can ask, but I bet they say no.
up to date, any method to unlock it?
Seriously?
I also have this problem, the boot loader is locked and I need to install the recovery. Prompt really working bootloader unlock method, none of the methods I did not ride. Through the website Sony have an error occurs, full of requests to install the update file, it weighs 1.5 gigabytes. I do not have as much Internet traffic to download it.
Currenty is possible if you are both rooted and in FW 303. Try this.
hi,all,im trying to unlock BL by flashtool beta6,but its say No loader found for this device
OS;4.2.2 ,423,HK
It says underneath it "cannot be officially unlocked"
So my guess is your bootloader is permanently locked. Type *#*#service#*#* and go to service info then configuration. It should say "bootloader unlock allowed:" yes if you are able to unlock it.

Use Google. A simple query like "how to unlock xperia z bootloader" would probably do it. But since that is such a far-fetched idea I understand how it could have slipped your mind...

Either try the latest flashtool and do it again or search for doomlord's post on how to unlock bootloader.
But before trying, I would highly recommend backing up your TA.img

Why are you using Flashtools Beta 6? That version has been superseded by the latest release on the flashtool site....
Go read Doomlord's post on unlocking the boot loader (which is the official Sony method)- you can do it quick and easy with fastboot......
As has already been said....read the post in Original Development about backing up your TA (DRM & BE) partition BEFORE you unlock your bootloader.

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
TA Partition backup
http://forum.xda-developers.com/showthread.php?t=2234627
so take it on ur own risk as im advising you not going for it!

andriod version is 4.4.4 stock rom --- C6602 ..
i have rooted my device with towel root app...
and also i dont get the pink notification light when i reboot the phone...
i think you need to install recovery
stock firmware don't have recovery
You need to install a recovery first, as this device doesn't have a stock recovery.
XZDualRecovery is currently the best (and only!) choice for locked bootloader devices. You need to download the installer package and run it from your PC to install the recovery the first time.

You're welcome.
If you purchased the device new and didn't unlock the bootloader, then it's definitely locked.
To check the status:
Enter *#*#7378423#*#* in the dialler.
Select "Service info".
Select "Configuration".
Look under "Rooting status".
If your bootloader is unlocked, it will say "Bootloader unlocked: Yes".
If it's locked, it will say either "Bootloader unlock allowed: Yes" or "Bootloader unlock allowed: No", depending on if you have an unlockable bootloader or not.
Hope that helps.

Happy to help.
Before unlocking your bootloader, it's important to backup your TA partition as DRM keys are erased when unlocking. This will permanently disable Bravia Engine 2 and screen mirroring and you won't be able to restore that functionality without a TA backup. More information and the required tool - Backup TA.
Once you've done that, here's a guide on how to unlock your bootloader - How to unlock the bootloader.

Are you using the latest version of the flashtool?
How are you checking that the bootloader is unlocked? Remember that there is a difference between "unlocked" and "unlockable". See here.

You didn't answer all of my questions.
If you re-lock without the TA partition, you will lose some of the Sony features. If you never backed it up, you can never get it back.
