good afternoon, I have a problem with my xperia z1 c6903 when unlocking the bootloader I get a message that says your phone can not be officially unlocked that I should thank.
Apparently Sony has blocked the ability to unlock the bootloader on certain devices.
This is most likely the case if you got your phone from your carrier. Do you have a branded Z1?
You can also look up if this is the case by doing the following:
1. Open dialler and enter *#*#7378423#*#*
2. Go to Service info > Configuration > Rooting Status.
3. "Bootloader unlock allowed" should say Yes
If it doesn't, then at least the official way of unlocking your device won't work.
Any "not official" way to unlock the bootloader? Mine is locked too and i want to install something new in that old one. Thanks in advance.
Mine says not posible but i read somewere that can be done
That's the thing, is an old smartphone today, i don't understand why only certains models can be unlocked. Now im on last oficial os (5.1.1). I get it root but i cant unlock the bootloader in any way.

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. Forgive me for asking but does this mean that there is absolutely no chance that at any point in the future I will be able to unlock it? I would like to use custom roms and want to know if I kight as well look for a new phone. This was never a problem on my old Optimus Black.
Thanks in advance.

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.

this may be true but it only works with bootloader that is allowed, he states in op that his bootloader is unlockable.
service menu shows if you can or not open bootloader, i am on 3 and my bootloader is locked have tried with sony code but get message not available.

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!

Yes, I meant *not* unlockable. I actually live in Spain so this service from Sony would be very useful, could you tell me how I can do this?

Yeah, mate. You have to send a message to Sony saying you've (sim) unlocked your phone and you want to unlock your bootloader. They will send you all the information you need to go through with the process.
I've recently bought a used xperia z but I'm not sure if the bootloader is locked or unlocked.
So my questions are:
1)How do I check this?
2)If the bootloader is locked does this guarantee me that the (stock) rom has not been "modified" previously?
My concerns at security related.

type *#*#7378423#*#* in the phone dialer
then service info>configuration>rooting status
we will have locked bootloader when we bought it
and no bootloader can be unlocked & relocked so don't know,or you can check if the BRAVIA Engine works on Sony Album app or not

According to this link you can but not entirely sure since I've never done it before..
If this if not the case, could you explain to me a little bit more?
It's possible to unlock and relock the bootloader without leaving any trace that it was done. You can check if it's currently unlocked by looking in the service menu. Enter *#*#7378423#*#* in the dialler, then look in Service info - Configuration.
If you're worried just repair the phone with SUS or the PC Companion. This will completely wipe the phone and reinstall the software from scratch, therefore ensuring that nothing is tampered with.

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.
http://forum.xda-developers.com/showthread.php?t=1896553
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.

Hi,
I have a Sony Xperia SP and to perform all the procedures to unlock the Bootloader in the initial part that says if our machine can unlock the bootloader or not , mine says it is not allowed .
My questions are:
Why is this unlock on some devices is allowed and others not?
Even if the information that shows my device , it is not possible to unlock the bootloader , I wonder if there's another way to do it or even impossible to do ?

Your service provider doesn't want you to unlock your bootloader and there is no way of unlocking if it says not allowed.

Thank you!
By the way... do you now if its possible, someday, create the version 4.4 KitKat in *.ftf extension so I can install through the Flashtool?
In simple words no. But you can install cm11 on locked bootloaders. Just search for it in the development sections.
Hit thanks if helped.

I also have the bootloader status set to NO.At the moment,there is no way to make it say YES,unless you SIM unlock it(It must work,as in most cases it is the SIM lock which changes the status to NO).
hey i cannot unlockbootloader in service info bootloader not allowed which frimeware i can unlock bootloader?
hi there,
if the phone says in the service menu bootloader unlock allowed no means it cant be unlocked but that means you can still install a custom rom which should say LBL rom. Follow this guide: http://forum.xda-developers.com/xperia-sp/general/guide-flashing-custom-roms-ultimate-xsp-t2888579

Go to Xperia website, and search Unlock Bootloader, there you can select Xperia SP and see the number code type it on your cell phone to see if your cell can unlock the bootloader ( My English is more less bad, sorry for this I am Brazilian )

If it says "no." you can't unlock it. You can install custom ROMs as long they are stated that are for Locked Bootloders. Do not attempt to flash a ULB ROM onto a Xperia SP with a LBL because it will soft brick your phone. Attempting to unlock the bootloader when the the status says "no" it's not recommendable and could hard brick your phone.

As mentioned above, if the phone says "no" or doesn't say anything at "bootloader unlock allowed:" thing, then there's no way around that. You can still get custom roms though. There are some roms that will work with locked bootloaders.
Pro tip: Always buy generic phones if you want the best from xda. Always check what you're going to buy.
