The easier way would be manually downloading 4.4.2 ftf and flash it using flashtool
download ftf from here
download flashtool from here
Make a backup before flashing ftf though as it will wipe the internal memory

You need to buy a unlocked bootloader phone. I'm with a lock bootloader too...

If yours are in 4.1.2, downgrade to 4.0.4 and check Boot Loader unlock status again. Good luck.

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.

Have you tried it?
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.

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

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.

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

I have an issue.
I'm trying to flash my phone. However Emma is saying that the phone is locked. Then when I go through the steps to unlock my phone, it says I need to use Emma. But I can't use Emma because it keeps saying the phone is unlocked.
This makes no sense.

You don't have to unlock bootloader to flash stock sony rom. Use flashtool from flashtool.net
Thank you.
Flashtool thinks I have an X10 ????
How is it supposed to flash my phone if it doesnt know what model i have ?
That flash tool doesnt work. Does anyone know of any others that might help ?

You can root your ROM by using Towelroot and then install this recovery.

As you're still using a stock based rom, open the dialer and type *#*#7378423#*#*
This will open the service menu, check under general service info (if I remember correctly). You'll find there whether or not your bootloader is unlocked.
Download flashtool by androxyde and the rom you want to flash (you'll find it here on the forum) and flash it via flashtool.
If your bootloader is unlocked, lock it with flashtool (though it won't make any difference as I'm pretty sure you didn't back up your DRM keys)

by installing stock rom i meant to say android 5.1.1 firmware..
and in that service menu it says
bootloader unlocked allowed:yes..
so does it means i have alrady unlocked or it is locked and unlocking is allowed?

It means your bootloader is unlockable, but currently locked. You do still have your TA partition and DRM keys. To install stock 5.1.1 you can also use sony pc companion, it should be the easiest way. All your current data might be lost, though
