In general, I would like ask about unlocking my Xperia LT30AT. I've unlocked a phone before but it has been a long time.
I seem to recall that when I unlocked my first phone, I downloaded a developer kit that you use to root and unlock the device. I am interested in doing that to my LT30at, but I don't want to use any custom roms like Cyanogenmod.
What I would like most of all to do: to
(1) root and unlock the phone,
(2) keep the (functionally) authentic Android OS, and
(3) Get all the AT&T apps off the phone for good.
...but I would settle for just the first one, for starters.
Any suggestions? Thanks! MX

it's interesting to me for the same model lt30at.
In addition I wanted to know if you lose your 4G LTE Thanks to all who respond
* P.S. many links to files in the root of the sony t is no longer usable
To root this device you should use the flashtool, you can't unlock bootloader at all. Me I rooted it added a recovery. Then flashed a unbranded firmware via the. Recovery. Kept root that caused everything to work pretty Ok now my att TL is rooted with 4.3 with a few bugs

Since you want the phone to be rooted, you have only 2 options:
1) If you want to stay on 4.1.2: flash any generic 4.1.2 FTF using Flashtool and exclude the baseband in the process, then root the device.
2) If you want to upgrade to 4.3: follow the guide in my signature.
Bootloader cannot be unlocked.

If you update to 4.3 using Flashtool you will lose root access to the device because there is no exploit available yet. Carrier lock is SIM lock and is managed separately from ROMs.

Are you sure it's "bootliader unlock allowed: yes"? LT30at have always come with locked bootloader.
Carrier lock us SIM Lock. As I've said before it's nit affected by any kind of flashing. It's stored in a different location.

Yes , Bootloader unlock allowed in my device is YES . Firmware is 9.1.F.1.120 , android 4.1.2
So can i update my device to 4.3 ?
You're probably the first person I've seen with a TL with at&t firmware (I'm assuming since it's 120 firmware) that has an unlockable bootloader.
Yea I must 2nd that how did that happen

can any one say what to do for getting permission for unlocking boot loader
Short answer - you can't unlock it ever.
The only exception would be if the status changed to disallowed after rooting. There is a fix for that somewhere in Doomlord's rooting thread.

Short answer:
If your device says Bootloader Unlock Allowed: No, it means you CAN'T unlock your bootloader.

Unless it was rooted, as this sometimes changes the status to 'No' as stated in the first post of Doomlord's thread. I used bin4ry's tool and the bootloader status was untouched.
Edit:
DooMLoRD said:
if u had an unlockable bootloader device, after using this method the device will be detected as LOCKED or unlock not possible!!! (to fix this use this fix)
...........
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 )

Hello, everyone.
I know nothing about rooting, flashing or unlocking bootloader. What I really need is to unlock the network of my phone. It was bought in Portugal locked to the TMN network. I am now back to Brazil and want to use it here. The conventional method of unlocking network is buying a code, but I want to know if there's a way to do it with no expense. What do you guys recommend?

Hello and welcome to the forums.
The only way to network unlock this device is with a code, either from the original network provider or from an online seller. It is not possible to unlock any other way.
Additionally, as you're new here, I will suggest you should start a new thread when you have a question in future instead of bumping a very old thread unrelated to your question.

Hi, welcome to the forums.
This is the Xperia Z section. You should ask questions regarding the Xperia Z3 in the Xperia Z3 Q&A, Help & Troubleshooting forum.
Sent from my C6603
I'm thankful that there are still wanting to address this issue of the bootloader not being unlocked. So my question is as such - Is there anyway (either by contacting T-Mobile, or Sony) that my phone, which is is SIM Unlocked (I know SIM unlock has nothing to do with bootloader unlock), can be bootloader unlocked? I'm just hoping that I can either get with Sony/Tmobile and have them do it, or even if there is a legitimate paid service out there then I will do that too! Any kind of help or anything would be appreciated! All I read is, 'If you're bootloader says no than that means NO', or I will often see people say that their bootloader says no and yet they can still enter fastboot mode.
Currently my device is Sony Xperia Z C6606 Tmobile version. I'm going to try to switch out my microUSB cord and see if fastboot works then. I'm still trying to have some kind of hope that maybe it will somehow work and I can flash a custom rom. Currently, whenever I plug in my phone into any computer, (with drivers installed) it never even shows up in the Device manager so I'm thinking it's an issue with my cord. It charges the device only.
Or should I just sell this phone and get a different android phone where I can unlock the bootloader? lol
Thanks!
You can only flash stock based roms with a stock, unmodified kernel.
Fastboot will connect even with a locked bootloader, but the commands you can use are extremely limited and in your case you cannot do anything with it at all. Your USB cable is not the problem.
If you want to flash CM/PA/AOSP etc, then you'll have to buy a new device. The bootloader is non unlockable. Nobody has cracked the security yet and I don't think anyone is even working on it, to be honest.
Sony or T-Mobile will not unlock it.

Rooting does not void warranty, who told you that.. There is a difference between rooting and bootloader unlocking. To change your customization number, you need to root without bootloader unlock. By the way, after flashing the new firmware, every trace of the root will be erased, so nobody will ever know that you rooted your phone temporary.

Many websites say 'rooting' when they actually mean 'bootloader unlocking'. On that website, they're talking about bricking your phone and custom ROMs. That means they mean 'bootloader unlocking', because custom ROMs are not possible with a locked bootloader. While it's possible to root your phone by unlocking the bootloader, that is not always required.
For many Xperia devices, we have software exploits that allow to root your phone without touching the TA partition or bootloader. This means that all traces of the root will be erased if you flash clean stock firmware and Sony will never know.
This is not the case when you unlock your bootloader. If you created a backup of your TA partition before unlocking the bootloader, you could always restore your phone to factory state, but Sony will still know that you requested a bootloader unlock key.
Like I already said, you only have to root your phone temporary to change your customization number, without unlocking your bootloader. After flashing the new firmware, all traces of the root will be gone, so this method is completely safe and will not void your warranty.
By the way, did you edit your original post? I see you're asking firmware version 10.3.A.0.423 now. This is currently only available for the 'Generic TW' customization for C6602. This can be used perfectly in Europe and USA however. It contains all languages. You can find an FTF here: http://forum.xda-developers.com/showthread.php?t=2337838 or change your customization number to 1270-5691 and update with Sony PC Companion.

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.

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

so....no, you will not unlock your bootloader easily your way

That's only to back up TA upgrading with root from 4.2.2 is to 4.3 or 4.4 is not supported.

As for unlocking bootloader there's no hope. But you can still get root by flashing pre-rooted firmware in the link I provided in previous post. Just follow the locked bootloader instructions.
yup owns Z1 and stuff. Also if I've helped you don't forget to hit THANKS - actions speak louder that words.

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
