Ofcourse not. There is no way to unlock your bootloader when it's locked with allowed = 'no'.

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.

Flashing an older firmware version to a phone with non-unlockable bootloader will not solve the problem, as common retail firmware images from Sony do not alter the bootloader.

If yours are in 4.1.2, downgrade to 4.0.4 and check Boot Loader unlock status again. Good luck.
this actually makes sense. to network unlock my xperia x10 i had to downgrade to frayo and use some kinda unlock software from fastgsm.com i think, unlock it upgrade back to gingerbread now bootloader status went from all caps to common ( rooted) idk how come

Have you ever tried it? My phone is TX, with 4.0.4 stock , bootloader status unlock said "yes", I upgraded to 4.1.2 and status said "no", did rollback to stock 4.0.4, I unlocked my TX bootloader. Do not give advice when you do not know it surely. I did it my own hand.

It wouldn't be that easy don't get your hopes up now I could see maybe if some one found some way to do it like with the test point method with the Xperia arc it would be possible but I've previously looked around and haven't seen any body able to unlock there bootloader on this phone just yet I haven't taken a look lately but as far as I know it's not happening as of yet.

Gasai Yuno knows what he talk about

Maybe you rooted it on 4.1.2, and that's how it ended up like this.
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
