Spanish users have the choice of unlock their bootloader freely through official Sony support, maybe in other countries this facility is available too. You just need to send an email request like this (change bold inputs):

Sony pickups and returns the device with no cost in less than a week. Take in account that both phone data and DRM keys will be lost.

Stay away skeptics. I can not guarantee that official unlocking is available in all countries, but in Spain it is.

[Sony Xperia T, TL, TX, V] TiMiN8R:
Tried and failed. I followed letama's porting instructions but after the Sony logo it just hangs at a black screen indefinitely. Never see a colored led so it must be either in the pre_hw_config.sh or step2.sh. Might have another go this weekend.
[Sony Xperia T, TL, TX, V] Olivier:
You have to edit LED variables for Xperia T...

Did you use letama's busybox? Stock CyanogenMod one will not work because it's linked dynamically. Just copy it the /system/xbin.

And also, you have to comment all the lines in *.rc files )in cm.tar (ramdisk)) saying exec /system/bin/pre_hw_config.sh, in other words, it must not be executed (we don't want an endless loop).

If you have done all of the above and it still hangs at a black screen, it could be a driver issue. Make sure the kernel of the ROM you are porting uses the same video drivers as the stock kernel.

[Sony Xperia T, TL, TX, V] Blagus:
That loki stuff won't work as-is since Sony has it's own S1Boot bootloader not based on LK.

I didn't investigate what actually happens during S1Boot's verification process to know if S1Boot would be exploitable same way as Loki method, but I can give a tiny something what would help understanding how exactly S1Boot handles the unlock key and how it unlocks the partitions internally, to some serious (recognized?) developer who's working on this. It's not too much and I have no idea if anyone already knows this. I left the scene completely after my Xperia Play was stolen so I lost the track completely.

It would be a big breakthrough if someone found a vulnerability in S1 bootloader since it didn't happen yet in all the years of S1 platform, back from pre-smartphone era.

I was doing someresearch about locked bootloaders and rooting the z1 andcame accross the below link have ot tried yet but wanted to ask how genuine is this.

Please
[Sony Xperia T, TL, TX, V] barry1979:
other option possible?

Excuse me for what maybe a simple or already tried suggestion, but ive been reading about methods to try and unlock this bl and I for one would be interested in trying to help in any way possible as I have the xperia tablet z with bootloader unlock=no scenario.

Would it be possible as we can only flash stock kernels to try and pull a stock kernel with unlock capabilities from a device and write to a locked bootloader device would that possibly give a unlockable scenario? Sorry if this sounds wrong or anything like that but its just a thought I had as there will be a way arojnd this as nothing is secure completely. Unfortunately im not an android developer although I am trying to learn these things and would like to help if I can.
[Sony Xperia T, TL, TX, V] Mad Marty:
The unlock code is on the TA partition of I remember correctly, not in the kernel. The kernel gets its information about locked/unlocked status from the TA partition. Simply replacing the TA partition will also not work.
[Sony Xperia T, TL, TX, V] mirhl:
[MENTION=5852284]barry1979[/MENTION] [MENTION=3529916]Mad Marty[/MENTION]

it's not the kernel merit or fault, it's the bootloader which matters.

When phone starts, it checks TA partition. If this says it's locked then vendor sign is checked and custom kernels aren't executed
[Sony Xperia T, TL, TX, V] king960:
Don't bother, there's no hope. 2 years passed for me.
[Sony Xperia T, TL, TX, V] barry1979:

I know this thread died long ago but has anyone tried to do pork explosion in this device? i think foxcom manufactured some of sony's devices.
[Sony Xperia T, TL, TX, V] KieMarshall:
this sounds good... I'm not really an android developer. but i am a developer by nature ( i work in systems development ) and from what i can tell the issue is unlockable boot loader phones have a different boot loader as they can open into fast boot where as our phones ( not unlockable ) will not boot into fast boot. my assumption is that the boot loader in our phones doesn't initialise the fast boot protocol which makes it VERY difficult to get the phone to accept low level commands.

like i said im not a developer, but thats what i understand.
[Sony Xperia T, TL, TX, V] vinss68:
Maybe we can ask some help from zdzihu, azuzu or ktg team, They participate to crack the bootloader and create custom kernel for locked bootloader in x10 day
[Sony Xperia T, TL, TX, V] gregbradley:
All phones can boot into fastboot. Its just those that can be unlocked can install custom kernels. Those that are locked can only flash stock kernels.

Try turning off your phone, and attaching the usb with power up pressed.

The led will go blue and you are in fastboot mode

Try the following

fastboot devices

It will tell you that you are connected in fastboot

also this

fastboot flash boot kernel.elf

will successfully flash a stock kernel to your phone as long as the kernel.elf has been extracted from a ftf file.

Its a moot point, but just shows that fastboot is available for all phones

From what I know no one has heard from zdzihu in a LONG time...
[Sony Xperia T, TL, TX, V] istux:
My device is unbranded and unlockable.

I haven't unlocked it yet, because I don't want to loose DRM keys and my warranty. :(

Anyway, I observed one strange thing: when I flash the original rom with FTF file, my T is unlockable.

After the root with Bin4ry's method, my T become NOT unlockable.

Then, when I flash a custom rom, my T turns unlockable again.

Maybe this could be a good starting point? :confused:
[Sony Xperia T, TL, TX, V] gregbradley:
its already been discussed, and is not a potential hack as this is just a wrong reporting of the status as opposed to anything actually changing.

In this case when your bootloader unlock says no, you can still actually unlock it, it is just being reported incorrectly
[Sony Xperia T, TL, TX, V] istux:
I got it....what a pity! :rolleyes:

Well, I donate 10 euros if someone find a way to unlock bootloader without loosing DRM keys :fingers-crossed:
[Sony Xperia T, TL, TX, V] lee480:
There's actually a highly successful experiment to backup and restore your TA and DRM after unlocking.

http://xdaforums.com/showthread.php?t=2234627&page=69
[Sony Xperia T, TL, TX, V] gregbradley:
yes. but don't you have to relock to restore that TA? And then your custom kernel goes.

Correct me if I am wrong, but I am under the impression that you cannot be unlocked AND restore the TA. But in this method you can relock then restore then TA.

I personally don't see the benefit if this is the case, but if I am wrong it could be useful for those that want drm keys
[Sony Xperia T, TL, TX, V] lee480:
DRM keys are useful for people who needs to send in their phone for warranty. Sony can reject phones if DRM keys arent present.
[Sony Xperia T, TL, TX, V] istux:
It sounds really really good.... has someone ever tried this method on a device that wouldn't be a xperia Z?

The greatest benefit is that you don't affect your warranty. You could relock and restore the TA, if you need repairing.

The second benefit is that you can resell your phone as an "untouched" device.

The third benefit is that if you discover that custom roms based on stock rom are enough for your needs and you want your BE (TrackID and so on...) back, now you can.

Not bad at all! :D
[Sony Xperia T, TL, TX, V] gregbradley:
yes I know that, but if you have unlocked the phone via the official way they have a record of your IMEI number....

It does not say that you have unlocked, but there are other ways to see if the phone has been unlocked than drm keys.

Been tried and a few hard bricks were the result. And I mean hard bricks, not a soft brick.

Messing with the TA is VERY dangerous

Fair enough, I see your point on returning for repair, but beware of my previous post..., Also track ID works for me and I am on unlocked bootloader, and I have never actually seen any difference when using BE or BE2 or no BE. And my eyes 20|20 vision.

The .TA file I think is the way to go as it controlls all features of the bootloader and such.

ETC when you sim unlock your phone, it goes to the .TA. When a phone gets locked by OEM is controlled by .TA and has been proven many times. Its just gonna be hard to unlock the device using it tho
