Bootloader unlock allowed: no - Sony Xperia XZ1 Compact Questions & Answers

Hey,
I wanted to root my XZ1 compact, unfortunaly I realized that my bootloader is unable to be unlocked.
I am a bit confused, as I thought the unlocking is not allowed if your phone is blocked by your carrier, but this phone doesn't have a branding and has no simlock.
Are there other reasons why a bootloader unlocking isn't allowed?
I got this phone as a display model from I think it was UK, perhaps this could be why.
If someone has an idea if there could be a way to unlock, I would be very grateful, even though I know that it doesn't seem possible.
Edit: Ok I think the bootloader is still blocked by the carrier MyEE, their app is on the phone. So it's probably because of them that the phone is blocked, even though I can use other SIM cards...
If somebody knows what I could do to unblock the bootloader, please tell me.
Thank you!

If the phone came from EE or any other carrier the BL will be locked, getting a code to unlock the sim won't unlock the BL, so unfortunately you're stuck with a BL locked phone.

[Q] unlock bootloader in SIM locked phone

I couldn't find anything by searching the older threads so here is my question:
Is it possible (and reasonably save) to try and unlock the bootloader in a SIM locked x8? Just to clarify: I don't want to remove the SIM lock from my phone - I'm happy with my current provider. I'm just wondering if I can unlock the bootloader while I still have a SIM lock on my phone.
All the threads about unlocking seemed to be concerned about how the phone was SIM unlocked rather than whether it was actually necessary...
Thanks a lot in advance..!
anyone please?
I just want to know if I can unlock my bootloader while I still have a SIM lock in place. Or will I brick my phone then? I don't want to remove the SIM lock. Just flash a custom kernel so I can get proper wifi tether...
same question... now,why is necessary have unlocked by operator the phone ???
is very maddening D:
so so please developers unlock bootloader with phone locked by operator, many peoples will thank you

Am I dumb? Re: Unlocking

Hi. The day I got the HTC One (from Bell) I went through the "unlock bootloader" and rooting process. Everything went fine and I've been using various ROMs and Kernels.
My question is: Is my phone "unlocked" as in able to be used with other carriers? I thought that's what unlocking the bootloader is.
I'm asking this because I got a SIM card for cheap roaming in the US, which I tried to test yesterday. When I booted the phone after putting in the Roam sim card, it prompted me to enter an 8 digit access (or pin) code. I had no idea what that was. And when I called support they said I would get that prompt if my phone wasn't unlocked.
So... is unlocking bootloader the same as unlocking from a specific carrier?
Yes, you can use all carrer if your phone isn't SIMLocked by the carrier.
So, seems that your sim is blocked, 8 digit for pin is the puk for unlock your sim.
How can I know 100% if my phone is unlocked? (other than inserting a SIM from another carriers). Is there something in settings that indicates unlocked?

I'm not sure what you mean. The phone was originally branded with Bell Canada. Then I unlocked the bootloader and rooted.

Unlocking the bootloader has nothing to do with unlocking the phone to use on other carriers. Your device is still SIM locked If you want to be able to use your phone with another carrier's SIM card, you will have to find a website that provides such service, like cellunlocker.netcellunlocker.net

I think the lt30a is the AT&T phone. You may be able to get an unlock code from them. I had no problem getting an unlock code from AT&T when I sold my S3 to buy this phone.
EDIT: I read this wrong. the AT&T version is lt30at. Sorry.
yes.
from what i undestand it was bought in uk.
some people are confusing the 2 unlock types
Just in case, the sim unlock process is a simple one, just insert another sim from the other provider and enter the code provided.
Unlocking the bootloader is not possible with some versions including the lt30a - at least a method does not yet exist - unless you are working with the models that have unlocking enabled. Check other posts which cover this topic extensively.
yes i know it asks for the SIM network unlock PIN, i do not have one.
and also i know that the bootloader isn't unlockable, i've checked in service info. i don't need unlocked bootloader for now as i have rooted the latest stock 4.1.2, only problem i have it with the sim lock..
got the sim network unlock pin from network operator, thread can be closed
Or put [solved] in the title

[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.
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.

[Q] Q: Simlock & Bootloader Lock

I'm looking into buying a used SP and I got somewhat confused about sim- and bootloaderlocks.
If I get a (cheaper) simlocked phone - is there a chance the bootloader is unlockable? (Guess not since it would help in removing the simlock...)
Given a simlocked phone with 'bootloader unlock allowed:no' - will having a phoneshop remove the simlock result in an unlockable state?
Do I have to get a factory unlocked non-carrier-branded phone to get unlockability?
If not - how do I recognize unlockable ones prior to the sim-unlock?
Edit:
Shops in my country charge about 45 dollars for unlocking sony phones. Is there any detriment in using a web-based service instead?
Can someone recommend a trustworthy one they've used themselves? How much was it and how long did it take?
Thanks for your insights

You're basically flying blind unless you buy a factory sim unlocked phone which should have the bootloader unlockable. If the carrier has simlocked it then they usually bootloader lock it too.
