Well..i am not sure what kind of locked device is this. We don't have career locked phones in my country. They sell it without any lock...
can anyone explain it what kind of lock is this ? and it's not even allowing to root...

Bootloader locked means u cannot load anything at boot that would tinker with the basic core of the device, like u cannot use custom kernels when ur bootloader is locked that is y ppl unlock their boot loaders Google for further info.
As for the OP's problem :
This is a known issue when u root ur device without unlocking bootloader, the solution to this is to do a full repair using Sony Suite which will result in loss of all data phone ,SD card etc .
check this link out its clearly stated over there
http://forum.xda-developers.com/showthread.php?t=2186368
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 <yet to be confirmed>)
ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC

How so some people can unlock the bootloader and some can't??

[Q] Unlocking 'Bootloader Unlock = NO

Hello,
Currently my Xperia T's 'Bootloader Unlock' is set to No. I was wondering if any attention or development is happening to unlock locked bootloaders?
Is there something in the works, or is it being left alone since there are devices that have bootloaders that are unlockable?
Thanks,
W.

You can flash roms that are for locked bootloaders "hint hint" Xperia T Android Development "hint"
But If you flash a unlocked bootloader rom on to a locked bootloader it wont work and will just vibrate (which leads you into recovering in flash mode)
There is this thing called flashing .TA to try to unlock but you have a 50% your device will be hard bricked, 95% it wont work and 100% will disable radio.
Flashing a .TA is dangerous, and could just hard brick your phone
If you want to take the risks then do it here

Hi AndroidHC,
Thanks for the quick reply. Yeah I'm aware of the ROMs available =). That's what prompted my question because there's a ROM I wanted to flash but it requires an unlocked bootloader and wanted to know what options were available for unlockable bootloaders.
Thanks for the link to the other forum. It's tempting but I think I'll hold off on that workaround.
Regards,
W.
Definitely do NOT try that.
Currently there is no way to unlock your bootloader on this phone if it says no.

Out of curiosity is there anyone working on a bootloader unlock or is that unlikely to happen anytime soon?
I am not sure, but people like blagus and the_laser who are very rarely on xda often pop out of nowhere with something special.
I am sure someone will be working on it...

Thanks for chiming in streather =) That's the point I was initially trying to get across
I remember the_laser and blagus from my X10 days. I'd love to hear from them if there is an initiative going on behind the scenes to unlock bootloaders that are set to 'No'.

If you rooted your Phone with Bin4ry it says that you cant unlock bootloader, get your Phone to stock(factory reset) then its gonna say YES again/

not necessarily, only if it was allowed before rooting by bin4ry method.
This only happens as a by product of bin4rys method make an error in the reporting of the status, it does not actually change the status.
So,
Without the bootloader locked, a new kernel isnt possible?
If thats the case, can an OTA update from Sony update the kernel?
yes, official kernel can be updated ... but without unlock BL you cant flash custom kernels.

[Q] Bravia Engine - Is it worth it?

Hi, my bootloader is suddenly unlockable since the .244 firmware update from Sony. So my question is this: is it worth losing the Bravia Engine by unlocking my bootloader? Is the Bravia Engine really a feature worth having on the XZ and are there any substitutes?

If your Phone came from a carrier then it isn't unlockable regardless of the change in status.

Sad news :crying: thanks. XperienceD what's your take on Bravia anyway? Is it worth keeping a locked bootloader for Bravia Engine?
I unlocked my bootloader as soon as I got my phone. I would rather have an unlocked bootloader so I have the ability to flash custom roms and kernels then seen the colours a little brighter when watching videos and viewing pictures.

Yeah well the biggest downside to locked bootloader is no chance of AOSP roms :crying: luckily most of the Xperia's UI is pretty cool, particularly the Honami email, messaging and contacts. So after XperienceD's news about bootloader being locked if the handset came from a carrier, I can live with it for now... gonna try unlock it anyway

I'd prefer to keep it but would happily sacrifice it for the ability to be able to unlock my BL. You can try for nothing but if it does come from a carrier then I've yet to see anyone who has reported this change in status then go on to unlock it. I'll never have another Phone from a carrier that's for sure.
Is it worth?
Simply. Yes. That's my opinion.
Btw, I unlocked bootloader and I still have BE2, all these DRM keys. Is it normal?
Seems http://unlockbootloader.sonymobile.com/ is intermittently down tonight loaded the web page earlier but can't load it now. Will check it out tomorrow, my phone is from Vodacom so it's a carrier phone.. this will be an interesting test. Is it normal for Sonymobile website to be down? "The website encountered an unexpected error. Please try again later." Poor show if it is..
Can anyone confirm if you're getting an error on this link: http://unlockbootloader.sonymobile.com/

It worked, unlocked my bootloader with a carrier issued handset I bought my phone from a dude when it was three months old. It came from Vodacom. It had the Vodafone logo splash screen when booting from stock and he showed me a photo of the registration screen at Vodacom when he picked it up. So I assume it was a carrier issued handset. Anyway, seems all is well now :highfive:
Bootloop on Sony logo after unlocking bootloader. What am I missing? Do I need to flash new .244 firmware and then flash custom rom?

I flashed .244 stock firmware in Flashtools and now it's fine. But I can't flash custom kernel, so I suppose that means my bootloader is still locked? But when I unlocked it, it said successful

Type *#*#7378423#*#* (service) in dialer.
Then open Service info > Configuration
Check "Rooting status"
if it says "Bootloader unlocked: Yes" guess what
if it says "Bootloader unlock allowed: Yes" or something like this, your bl isn't unlocked

Thanks, this makes sense! Mine says "Bootloader unlock allowed: Yes" so back to the drawing board..
When I unlock my bootloader, I know I'll lose my sdcard content but will I still be able to boot into the rom (I'm using monx for LB/UB) or do I need to re-flash?
Success!!
Success!! :highfive: thanks for the advice here, bootloader is now unlocked yes man :victory::victory:

Hey XperienceD, dunno how this happened. My bootloader changed from a status of unlock not allowed to unlock allowed after I flashed .244. Now I managed to unlock the bootloader, and it's a carrier phone from Vodacom in South Africa. Strange but true :victory:

This have nothing to do with Unlocking Bootloader. Unlock Butloader now and you will be fine, with 4.3 the camera was fixed.

Have you tried unlocking? When this has happened on Xperia T's the devices were still able to be unlocked even though that had changed. There is absolutely no risk in trying to unlock an unlockable bootloader, it will just fail in the process and will still boot no problem.
It has never been reported a NO had turned to YES, but some Yes had been turned to NO, and they were still bale to be unlocked.
And before anyone gets excited this is by no means something that can be used to unlocked bootloaders that are really locked, it is just a false reading of the boot status.

Ok, so it's risky. Is not a big problem even if you don't unlock the bootloader but are you sure was saying yes before? this is wired.
You can flash updates and custom roms anyway. Not custom kernels. Sorry.

[Q] Bootloader not allowed

Hi,
I have a Sony Xperia SP and to perform all the procedures to unlock the Bootloader in the initial part that says if our machine can unlock the bootloader or not , mine says it is not allowed .
My questions are:
Why is this unlock on some devices is allowed and others not?
Even if the information that shows my device , it is not possible to unlock the bootloader , I wonder if there's another way to do it or even impossible to do ?

Your service provider doesn't want you to unlock your bootloader and there is no way of unlocking if it says not allowed.

By the way... do you now if its possible, someday, create the version 4.4 KitKat in *.ftf extension so I can install through the Flashtool?
In simple words no. But you can install cm11 on locked bootloaders. Just search for it in the development sections.

Go to terminal in root mode and do
Code:

Than you can change the value and its not longer greyed out.

If that dosent work you can also follow the below procedure.
Relock your bootloader. Your phone will factory reset and boot. Then head to developer options and you will see oem unlock is not greyed out. Then just enable oem unlocking and unlock the bootloader. When you boot up again you will see that oem is greyed out but it'll be enabled. So you'll have unlocked fastboot and unlocked frp now.

I haven't gone that far. I've unlocked and then relocked.
Everything fine. I believe it's completely safe if you have complete stock firmware installed ie, stock rom, stock recovery, stock Kernal and all that stuff. Otherwise you'll end up in a loop. Guess I forgot that part sorry.
So I know this is someone else's thread but can you tell me if I relocked bootloader will the service center be able to know I'd unlocked before? I don't have the phone unlocked warning at boot. Just curious.

Some if not all bootloaders nowadays are not "locked" by the manufacturer using a code but are usually "locked" by employing a digital signature and/or a CID (carrier Id) hard coded into the OS. When we "unlock" a bootloader with a code we are simply using a routine written into the loader by the manufacturer to now ignore signatures and/or CIDs of the OS and this allows us to flash whatever we wish.
Sometimes upon unlocking using a code the DS/CID is erased/altered and cannot be retrieved, so not a good idea to relock an altered bootloader.
At least, that is my understanding of it.
