[Q] Bootloader not allowed - Xperia SP Q&A, Help & Troubleshooting

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).

Bootloader locked means u cannot load anything at boot that would tinker with the basic core of the device, like u cannot use custom kernels when ur bootloader is locked that is y ppl unlock their boot loaders Google for further info.
As for the OP's problem :
This is a known issue when u root ur device without unlocking bootloader, the solution to this is to do a full repair using Sony Suite which will result in loss of all data phone ,SD card etc .
check this link out its clearly stated over there
http://forum.xda-developers.com/showthread.php?t=2186368
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 <yet to be confirmed>)
ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC
How so some people can unlock the bootloader and some can't??

[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.

First time I checked, I was also disappointed, a few days later I realized that I checked the status without having a root phone. After I rooted the phone it said yes for me.

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.

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.

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.

[Q] Factory locked bootloader

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.

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!

[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.

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.

Could it be that you have got a sim locked phone? I a not sure but most sim locked phones have got a unlockable bootloader.
There are Z1s with:
Bootloader Unlock Allowed: Yes, and
Bootloader Unlock Allowed: No
It doesn't matter if you are SIM locked or not. SIM locked means you are tied to one specific Carrier and cannot use other Carrier's SIM. If you insert another Carrier's SIM it will not be recognized by the phone. You can have the phone "unlocked" meaning it will allow you so use any Carrier SIM you want to use but that doesn't you you have unlocked your bootloader.
If your phone says [Bootloader Unlock Allowed: Yes], you can unlock it using Flashtool or go to Sony's website.
If your phone says [Bootloader Unlock Allowed: No], sorry mate - you don't have any way of unlocking your bootloader.

That's the reality.
As already said only phones with 'bootloader unlock Allowed: yes' can be unlocked.
If this is my phone I would be interested in knowing why my bootloader isn't unlockable and I would write to Sony.

None that I know of personally. I did a Google search - I found a youtube video but I doubt it's credibility. But I am not an Advanced Developer or anything like that. I'm just another guy with an Android phone. And from what I've read so far, if your phone says [Bootloader Unlock Allowed: No] that means:
"No.",
"Sorry but No!",
"Nooooo-Waaaayyy",
"uh-uh!", "Sorry, nope!",
"No can do.", "Nada!",
"Let me thing about it.... I say... No!"
"Hmmm.... nah!"
If your phone was purchased as a 2nd hand phone, the original owner must have purchased it as a SIM-locked phone and have later had it Open-lined so he/she can use any Carrier SIM he/she wants. But as I have mentioned before; which almost everybody gets confused about; if you have had your phone Open-lined it doesn't mean you have unlocked the bootloader as well.
