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] How to check if the bootloader is unlocked.

Hi there.
After i unlocked* the bootloader of my phone i got stuck in a bootloop, then i had to flash the TFT all over again...
The problem is that i don't know if the phone is already with bootloader unlocked or not...
how can i check it?
I was thinking on trying to do the unlock steps again, but i'm scared of being trapped on another bootloop...
Is there a way to check if the bootloader is already unlocked?
PS: The bootloader unlock allowed is yes.
thanks you guys.

Flash doom kernel via fastboot with this command:
Fastboot flash boot boot.img
If you get an error than your bootloader is not unlocked.
You can flash back to stock kernel with flashtool,flash the kernel separately.

but if i got that error and confirm that the bootloader is locked, is there any chance to harm the phone? or need to flash the TFT again, etc etc

use flashtool to tell you

Another more easy approach .
When bootloader unlock allowed says yes and be2 is working in Album, then it is still locked and you can start the unlock steps again.

How can i use flashtool to tell me?
@DevShaft
Before i could see in a flash the bravia engine working on pictures. There was a little delay... Now i can't see it.
Probably the bootloader is unlock.
If i try to install Doom's kernel via recovery and the bootloader is LOCKED, can it do any harm? thanks guys

bootloop and u will have to use FTF to fix it.

Thanks man.
I'll wait the new firmware or android 4.2 to see it.

I unlocked my Xperia Z and in Service Mode I can see 'Bootloader unlocked: Yes'.
Now my phone is running on latest C6603 firmware and DooM Kernel.
To my surprise, BE2 still works! Music info download still works! TrackID still works!:victory:

But not picture enhancement in album right? Hope you backed up TA partition before unlocking

im surprised at how this 'check bootloader is unlocked already or not' thread is confusing.
by the previous post, there is two 2 ways
1. try to flash doomlords kernel via fastboot, and if it doesnt flash means its NOT unlocked.
2. flashtool.
however the 2. flashtool method is very vague.. dont think anyone elaborated it.
So my same query is that if some error occurs after trying to unlock bootloader, and have reverted back to the stock FTF rom in original working state.
How do one check to see if my bootloader is unlocked or not?
whats the best easiest method???
Thank you!

just type in *#*#7378423#*#*
Go to Service Info > Configuration
And check the Rooting Status
If its Bootloader unlock allowed:Yes/No, then its not unlocked.
And if its Bootloader unlocked:Yes, then its unlocked.
Thanks

That just tells you weather you can unlock your bootloader via the command / flashtool e.g. If you carrier has locked your phone
On a unlocked bootloader the BE2 engine still works on videos ect just not pictures.
All I would do Is flash doom kernel or advanced stock kernel via flashtool (Click on lightning bolt /fast boot / click on put device in fastboot via adb now phone will enter fastboot then select kernel to flash which is in the middle on the pop up screen and then flash if it will take around 0 . 5 seconds ) if it fails then you bootloader is locked due to it cannot complete the command if is successful then it's unlocked and you can flash custom kernels take about 2 mins to do all in all

A little help about TA backup..

Guys need your help about this matter, I just bought my xperia z1 a week ago and i already rooted it... So my question is can i still back up my TA? I did not tamper my bootloader..how will i know if my bootloader is unlocked?
My process in rooting my xperia z1 is:
1st I downgrade my xperia z1 in 14.1.G.1.534 firmware and rooted it using vroot then upgrade it to the latest firmware which is 14.1.G.2.257... BTW I uninstall the vroot superuser because it's in chinese language and I can't understand it, but I replaced it Superuser in playstore and it works fine!...Thanks~
from Philippines

unless u visited the bootloader unlock website and requested for a key which involved keying in your imei number and then using fastboot to unlock bootloader, it's fine...
u can verify by checking if bravie engine works... or dial *#*#7378423#*#* and going to service info > config > rooting status

No, it means you are allowed to unlock it, but you have not done it yet otherwise it would say
bootloader unlocked: yes

trust me, you cannot accidentally unlock it...

Hahaha chewdaniel says to look at sevices menu if it's unlocked and i saw the word "yes" i thought i accidentally unlock it when performing to root it..i feel nervous when i saw it haha!
sent from future!

1. visit bootloader unlock website
2. key in your imei number
3. receive an email with unlock code
4. FINDING & INSTALLING FASTBOOT DRIVERS, while phone is in Fastboot state
5. entering bootloader unlock command with a very long and complicated unlock code
so yea... like Greg said... there's no way u can "accidentally unlock" it

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?

Yeah that's what I thought, but my bootloader is unlockable and I've done it the official way, twice!
How can I properly unlock it?

dial : *#*#7378423#*#* got to "service info" then to "configuration"
at the last line is it
bootloader unlocked : yes
or
bootloader unlock allowed : yes ( or something like that )

that only means that it's allowed but it won't say if it's locked or unlocked

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

It's not really unlocked.
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

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.

What version of flashtool. "Latest" is only relative. 0.9.19.6 just came out a day or two ago.
Post the entire flashtool log. Maybe something will show why this does not work for you.
