Unlock T-Mobile's Bootloader? - Xperia Z Q&A, Help & Troubleshooting

So I wanted to flash a ROM onto my Xperia Z because it wasn't waking from sleep all of a sudden, and after 12 hours of trying to get CWM and eventually forcing the 4.4.2 update instead of waiting for T-Mobile to release it OTA. I assumed my bootloader was unlocked, but then I found out that it wasn't because even Sony's official method wasn't working. (FAILED (Remote: Command not allowed)). I decided to google around to see if others had this issue, and came across a news site that said T-Mobile purposely restricted the bootloader, and it was unable to be unlocked.
The question is: Is there anyway around this issue? Is there any "official" way I can remedy this issue, such as buying the equipment outright from T-Mobile and requesting a SIM unlock or something?

Open the dialer and put *#*#7378423#*#* and go to service info >> configuration and see Rooting states
If its says bootloader unlock allowed: yes
So you can unlock the bootloader and if NO so no was to unlock it...

[Q] Xperia Z Bootloader?

Hey guys,
Just wondering if the Sony Xperia Z will come with a locked or unlocked bootloader?
if it is locked, can it easily be relocked after unlocking it for warranty purposes?
I know there isnt much info out right now, but i have never owned a sony xperia phone so,
someone shed some light for me?
Devices from carriers usually can't be unlocked. If you buy it outright then usually it can be unlocked. The process does not record your full IMEI and can be relocked after so you are pretty safe in that regard. My HTC takes the full IMEI (so it can be identified) and if you lock it then it goes to "re-locked" and not "unlocked" .... so the sony method is actually pretty good.
Before buying you can always check on a live unit if bootloader can be unlocked.

Ah okay thanks mate,
hmm new to Sony here too. So what are the chances of pre-orders from carriers being bootloader locked? Just to clarify, does that mean carrier purchased devices are useless (if they are locked)? I was planning to get my device from Orange Uk as i can get a pretty decent 40% off the monthly tariff which makes it the best deal for me. But if it is locked then I may need to pass on this....bummer

Well, if i recall correctly, the verizon droid DNA had a permanent locked bootloader too, but the guys here on XDA found a way to crack it.
who knows, maybe there will be a loophole discovered after the first few days?
I'm currently using a T-Mobile Xperia T, and the bootloader is not unlockable. So I would guess the same for the Z.
Though I think early units are generally unlocked (but don't quote me on that but this was the case with my Galaxy SIII and another guy mentioned this for UK network 3).

Is this just the way sony handles it's bootloader?
I unlocked several different phones which were ordered from a carrier without problem. Depends on the device itself!
But Sony seems to be very developer-friendly. There's a developer site on sonys website, where details about bootloaders are posted. Don't know the exact url atm, I'm at work...
For me it is essential to get a phone where bootloader can be unlocked. My first phone was a lg, without custom rom I would not use it anymore...
It all depends on the country. In The Netherlands all bootloaders can be unlocked, even if it are branded handsets from a carrier.
again as mentioned this is my first Sony Android device so please bare with me. Can someone explain the reasons to unlock the bootloader as from what i've seen people have said u still can flash ROMS with a locked bootloader?

If you're getting any sort of subsidy discount, it's highly likely your device will not be unlockable.
The general rule for Sonys is: If it is sold SIM-locked, you will not be able to unlock the bootloader. If it is sold SIM-unlocked, you'll be able to unlock the bootloader. If the carrier later gives you a SIM-unlock code for a device that is sold SIM-locked, your bootloader will remain locked (Sony is working on trying to change this with carriers).

Sony's bootloader security is pretty strong. If the Z were likely to have a loophole, the T would've probably been defeated by now.

You can cross-flash firmwares for other devices, but you cannot flash anything that has a modified kernel.
Thanks Entropy for your very helpful reply! I appreicate it
In regards to the discount, it is only because a friend works for them and in return are given a discount for friends and family. Otherwise it will be just the same as purchasing it direct from my carrier. My usual experience with purchasing a phone from a carrier, especially a newer phone which has 'just' (first batch usually) released is that they are usually simfree stock (sim unlocked), but heres hoping!
The Bell (Canada) Xperia ZL I have has an unlockable bootloader.
Only stok based roms... cm, miui, paranoid, etc bootloader must be unlocked so you can flash custom kernel
Sent from my LT26i
So therefore AOSP roms cannot run on a Locked bootloader due to requiring a different kernel. Where as variations/modded versions of Sony's rom can be flashed due to not requiring a custom kernel.
I think I understand now. The Sony rom looks decent to be honest which isn't something I can say about Touchwiz. It is actually skinned nicely and I wouldnt mind a de-bloated version of that.
I'm pretty sure sony will unlock it, judging from Sony's recent actions where they released the kernel source for the T if i'm not mistaken. Why wouldn't they do it for this monster phone right?

It's already listed on Sony's "Unlock Bootloader" site. So i guess they'll all unlock, unless you get it carrier branded/simlocked and they ( carrier ) will interfere with unlocking process.

I believe you need an unlocked bootloader to be able to boot the rom?
For htc devices, you need an unlocked bootloader, but it does not have to be S OFF.
If it was S ON, you just had to do an extra process of manual flashing the boot.img through fastboot
This is pretty simple if it's sim locked then it's also bootloader locked. The issue is not if you bought it on your carrier or on a retailer store. It's about locks

Depending on what you mean by "boot the rom" i am assuming you are referring to AOSP roms which use a different kernel to stock roms usually. Thus if you cannot flash a custom rom on the phone with a "locked" bootloader, you are stuck with stock Sony type roms. Don't mind it personally just sucks i cannot experience the great kernels that the XDA devs release. Fingers cross the first batch of pre orders will be unlocked though as they are usually sim unlocked in my experience.

50% true. As Entropy said the simlock can be "unlocked" by the carrier. This will therefore then be a sim unlocked device, but the bootloader remains locked. This needs to be clarified to Sony noobies like myself who may think sim unlocking will result in a unlocked bootloader, or by buying a sim unlocked device from say Ebay they have definately gotten a unlocked BL.

It's different again. With a locked bootloader you can't flash a custom kernel *at all*. I'm on a HOX now so I know all about the stupid htc bootloader unlock It basically means the device is useless for custom roms etc..
Still waiting to see if my local carrier will lock it or not, they have a mixed history with simlocking devices so could go either way. If it is locked I'll just pick get an iphone instead (should be roughly same price on contract) to sell on ebay and buy my sony outright I'll make it work one way or another.

[Q] bootloader not allowed xperia z

my phone is showing me that it cant unlock boot loader when i see in service test bt typing *#7378432#*#*
i am from india and using normal xperia z (not any docomo or any)
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.

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.

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.

Just received the XSP as an upgrade on T-Mobile UK and was disappointed to discover via the service menu that the bootloader is unlockable.

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 well the biggest downside to locked bootloader is no chance of AOSP roms :crying: luckily most of the Xperia's UI is pretty cool, particularly the Honami email, messaging and contacts.

I'd prefer to keep it but would happily sacrifice it for the ability to be able to unlock my BL. You can try for nothing but if it does come from a carrier then I've yet to see anyone who has reported this change in status then go on to unlock it. I'll never have another Phone from a carrier that's for sure.
Is it worth?
Simply. Yes. That's my opinion.
Btw, I unlocked bootloader and I still have BE2, all these DRM keys. Is it normal?
Seems http://unlockbootloader.sonymobile.com/ is intermittently down tonight loaded the web page earlier but can't load it now. Will check it out tomorrow, my phone is from Vodacom so it's a carrier phone.. this will be an interesting test. Is it normal for Sonymobile website to be down?

It worked, unlocked my bootloader with a carrier issued handset I bought my phone from a dude when it was three months old. It came from Vodacom. It had the Vodafone logo splash screen when booting from stock and he showed me a photo of the registration screen at Vodacom when he picked it up. So I assume it was a carrier issued handset. Anyway, seems all is well now :highfive:

I flashed .244 stock firmware in Flashtools and now it's fine. But I can't flash custom kernel, so I suppose that means my bootloader is still locked? But when I unlocked it, it said successful

Type *#*#7378423#*#* (service) in dialer.
Then open Service info > Configuration
Check "Rooting status"
if it says "Bootloader unlocked: Yes" guess what

Thanks, this makes sense! Mine says "Bootloader unlock allowed: Yes" so back to the drawing board..
When I unlock my bootloader, I know I'll lose my sdcard content but will I still be able to boot into the rom (I'm using monx for LB/UB) or do I need to re-flash?
Success!!
Success!! :highfive: thanks for the advice here, bootloader is now unlocked yes man :victory::victory:

I'd prefer to keep it but would happily sacrifice it for the ability to be able to unlock my BL. You can try for nothing but if it does come from a carrier then I've yet to see anyone who has reported this change in status then go on to unlock it. I'll never have another Phone from a carrier that's for sure.

Hey XperienceD, dunno how this happened. My bootloader changed from a status of unlock not allowed to unlock allowed after I flashed .244. Now I managed to unlock the bootloader, and it's a carrier phone from Vodacom in South Africa. Strange but true :victory:

[Q] Help: Sony Xperia Z1 says cannot unlock bootloader

How can I install a custom ROM without an unlocked bootloader?
My phone says its bootloader cannot be unlocked
Mine too , it's must to be a solution to unlock the bootloader...
No, there is no solution
If it says it cannot be unlocked then it cannot be unlocked
Look in the development section for stock based custom roms that can be installed with a locked bootloader
To my experience it needs to be sim unlocked first in order to be bootloader unlocked. In a Xperia Z it said it couldn't unlock bootloader, i purchased unlock code, got it unlocked and then reflashed stock image. After that the status on "bootloader unlock allowed" was changed to yes.

Please provide proof of that, because this has never happened before and would be fantastic news
Also, some sim locked phones can have bootloaders unlocked and some sim free phones have bootloaders that cannot be unlocked. SO your logic is wrong.

Can't provide proof as 1) the bootloader was already unlocked 2) I don't even have the phone anymore.
I don't know if you find my logic right or wrong it was what happened to MY experience with one phone.
I'm pretty sure devs can give you a technical explanation about why it can or can't happen.

OK thanks.
I know what the devs will say. They will say it cant happen. This has been talked about ad infinitum across various xperia devices.
Also, if your boot was already unlocked then how did you know the status changed?
Thanks anyway.

When i got the phone (telcel mexico) it said the bootloader was not allowed to be unlocked.
I purchased an unlock code. Entered the code, unlocked the phone.
I flashed an upgraded FW via FTF
typed *#*#SERVICE#*#* and boom bootloader unlock statys changed to yes
That's how i know the status changed. So basically that's my story. I thought it could work with every device.
@gregbradley maybe the sim unlock method really works to change unlock bootloader status YES..bcs it works for some sony device, and we need to test this on Z1.

There is nothing in that thread that confirms this. Plus the test point method to unofficially unlock the bootloader was stopped by Sony nearly 2 years ago.
But please, delve into this again if you want. But trust me it is a dead end and does not work. If it was easy as sim unlocking and flashing a ftf do you not think that would have been done by now.
Some seriously good devs have been working on this ever since the test point method was closed.
