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.

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.

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

Praise the (Doom)Lord! Will this allow us to unlock the boot then andflash custom roms?
Just to make it clear bootloader is locked this means no custom kernel which might mean custom ROMs are out ie. Cm,akop,PAC etc
You will be able to root using doomlord exploit and in time will get cwm for locked bootloader so we be able to use modded stock ROMs.
As it stands only root is available for locked bootloader hope this helps

Great, thanks. This is exactly what I needed to know. Guess I'll have to be patient then..
There is a way to unlock your bootloader. You must get a SIM unlock code, unlock your SP and send an email to Sony with some data like Imei, unlock code, etc. Then a messenger will be sent to pick your phone and lucky, Sony will unlock your phone.

Few days ago sent an email to Sony asking about this issue. Here in Spain there was a global complaint from Xperia U users asking for open the possibility of unlock their bootloaders: not to unlock it but to change the "unlockable" state of the phone. After the debate, Sony says people could send their phones to Sony attaching the respective unlock code with which they'd unlocked (SIM Unlock). Then Sony would send the telephones with the bootloader unlockable.
PS: Maybe he meant "not unlockable" instead "unlockable". If it's unlockable then he doesn't have any problem!

Yeah, mate. You have to send a message to Sony saying you've (sim) unlocked your phone and you want to unlock your bootloader. They will send you all the information you need to go through with the process.
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?

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

There's one case where your statement isn't true but it doesn't apply to AT&T Xperias, indeed.
Namely, if you use binary's rooting toolkit version 21 (and some other versions too) to obtain root on at least Xperia V (cannot say for the other models), the Service menu will show bootloader status as “unlock allowed: no” regardless of the actual bootloader lock state.

this is the the right point. and i think it should be a known Bug in the XT community
if you have bootloader unlock allow: yes
and then you root your 4.1.2
it will display bootloader unlock allow: no
but it is still unlockable (must be a little bug?!)
so....no, you will not unlock your bootloader easily your way
