You can unlock it. But you might want to backup your TA partition first before you unlock it. If you backup your TA partition before you unlock then your DRM are not lost forever.

Try to flash dooms custom kernel, if it fails then it's lock and if it's successful then unlock

[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.
thanks everyone.

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

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
TA Partition backup

so take it on ur own risk as im advising you not going for it!
good luck

To get rid of some bloat? Yes. To unlock bootloader? Not if it's locked by carrier.
Type *#*#7378423#*#* and check what saying Bootloader Unlock Allowed: Yes or No. If it's Yes you can unlock it and install Custom Kernels. If it's No you cannot Unlock it, ever. This is not Sim Unlock, and to do that you have to pay for it. Anyway with Locked Bootlader you can Root, Install Recovery and Unbrand your phone just Flashing Generic Unbranded FTF via Flashtool and you are fine.

Long time ago i saw a thread that a user was telling that he wasn't able to unlock the bootloader when he has using certain ftf files. It is pretty strange actually.
Try to downgrade your phone, maybe installing kk and try again mate.
Maybe this will help if you already don't know it. Take a look here. Way old that thread but maybe still guilty.

Congratulations. Glad I could help. You can give me a thank if you don't mind.
What do you mean with fresh kernel? You mean stock kernel, aren't you?

Can I install custom ROMs or recoveries using SP Flash Tool, but without unlocking my phone's bootloader?

Yeah the title says it all. Just wondering if that's possible or not since I'm not sure if I'd have to wait for a week for my phone to be unlocked, while I could get the job done in no time.
If unlocking the bootloader is required, then would force unlocking it using mtkclient work (triggers bootloop, haven't tried to relock it and see if it fixes it)? Or will it only work through official bootloader unlocking?
No, you need to unlock the bootloader in order to flash a recovery over the stock one

You need to unlock first, since locked bootloader will block any flash over system partitions
