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.

After getting my Xperia T unsuccessfully repaired(twice), the replacement phone has Bootloader Unlock Allowed = YES.
Yay! Now... to void my warranty...
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:
So my device says "Bootloader unlock allowed: No" under the "Rooting Status"
Am I just out of luck?
Yep, you and me both
People will try and say it is cause of the carriers, yet HTC, LG and Samsung phones on the same carriers are not all locked up. It is the one thing I don't like about this phone, well, that and the viewing angles (coming from a HTC one which had incredible speakers and screen)

Don't know about LG or Samsung but I know some HTC devices have their phones locked also when bought from a carrier. But we manage to workaround that issue by achieving S-Off so I guess yeah you're partially right.

So, it seems your phone should be Z1S, that's why all Z1S owners are not allowed to unlock their BL
So, here's the link to install CWM, and also it roots your phone with locked BL
http://techglen.com/2014/07/03/how-...xperia-z1-z1c-108-firmware-locked-bootloader/
It helped me a lot, although mine is Z1 C6903, but I locked BL and done step by step as it says
Wish you success

I don't think if C6916 has any Roms
Because its BL is locked, so you can not flash any Roms

so if I read it correct it says unlockable boot loader.
then yes it can be unlocked.

Yes, but I looked past the obvious incorrect grammar and undertood what he meant.
unlockable does mean that it is able to be unlocked
However, the user menat "un" is can not be unlocked.
The best bet is goto to
*#*#7378423#*#*
then goto service info / configuration
If the last line says
Bootloader unlock allowed: NO then it CAN NOT BE UNLOCKED
or
Bootloader unlock allwed: YES then IT CAN BE UNLOCKED
or
Bootloader unlocked: YES Then it has already been unlocked
I hope this clears it up

That's true, but since I have a contract phone from Vodafone (UK) and they do allow it, just saying so makes no difference.
How can I install a custom ROM without an unlocked bootloader?
My phone says its bootloader cannot be unlocked
Mine too , it's must to be a solution to unlock the bootloader...
No, there is no solution
If it says it cannot be unlocked then it cannot be unlocked
Look in the development section for stock based custom roms that can be installed with a locked bootloader
To my experience it needs to be sim unlocked first in order to be bootloader unlocked. In a Xperia Z it said it couldn't unlock bootloader, i purchased unlock code, got it unlocked and then reflashed stock image. After that the status on "bootloader unlock allowed" was changed to yes.

Please provide proof of that, because this has never happened before and would be fantastic news
Also, some sim locked phones can have bootloaders unlocked and some sim free phones have bootloaders that cannot be unlocked. SO your logic is wrong.

Can't provide proof as 1) the bootloader was already unlocked 2) I don't even have the phone anymore.
I don't know if you find my logic right or wrong it was what happened to MY experience with one phone.
I'm pretty sure devs can give you a technical explanation about why it can or can't happen.

I know what the devs will say. They will say it cant happen. This has been talked about ad infinitum across various xperia devices.
Also, if your boot was already unlocked then how did you know the status changed?

When i got the phone (telcel mexico) it said the bootloader was not allowed to be unlocked.
I purchased an unlock code. Entered the code, unlocked the phone.
I flashed an upgraded FW via FTF
typed *#*#SERVICE#*#* and boom bootloader unlock statys changed to yes
That's how i know the status changed. So basically that's my story. I thought it could work with every device.
@gregbradley maybe the sim unlock method really works to change unlock bootloader status YES..bcs it works for some sony device, and we need to test this on Z1.
http://forum.xda-developers.com/showthread.php?t=1896553
There is nothing in that thread that confirms this. Plus the test point method to unofficially unlock the bootloader was stopped by Sony nearly 2 years ago.
But please, delve into this again if you want. But trust me it is a dead end and does not work. If it was easy as sim unlocking and flashing a ftf do you not think that would have been done by now.
Some seriously good devs have been working on this ever since the test point method was closed.
