Bootloader not allowed - Sony Xperia XZ1 Questions & Answers

Okay, so I'm guessing this is a question that gets asked a lot, but honestly I couldn't really find a definite answer, so i figured I'd just ask.
I recently got an XZ1. The Model number in the service menu is G8341, if that matters. And in the configuration tab, it says "Bootloader unlock allowed: No". I'm guessing this is a block that Sony put on there for whatever reason. Is there any way at all to circumvent/fix this and unlock the bootloader anyway so I can root my device and install a different ROM? Cause if not, I'm gonna send it back.
Thanks in advance.

I think it's not worth rummaging in the phone system. The consequences can be deplorable and the benefit is small. That's why I advise you not to change anything. Not worth it.

If it says 'unlock allowed: no' its not possible to unlock the bootloader. Is it a carrier branded phone?

Bootlock allowed=No phones are contract phones from providers. They don't want the hassle of "waa, I unlocked my phone and now it's broke" so they just disable it.
There is no way round it.

[Q] Sim unlock question

My question is why there is no software that can sim unlock xperia x10, i mean access has been obtained to the bootloader and everything inside, i dont understand why there is no method to sim unlock this cellphone, other android cellphones that are succesfully rooted and hacked their bootloader are super easy to sim unlock just one button press like samsung galaxy so my question is why cant they acess the area where the lock is stored and erase it or replace it with an unlocked register, im really interested in this info, if someone answers me or points me in the right direction it would be really appreciated, im pretty sure there is no method and i want to create one, probably imposibly difficult but i want to try.

I dont have a technical answer to why its not possible but yes the answe is no. Theres no possible way to sim unlock your phone.
Galaxy phone capable of being unlocked already have the unlock code hidden in some file which we dont have.

[Q] How to unlock bootloader? Allowed: NO 12w23

Hi people, after searching a lot, i just wanna make sure there is no way to get this done,
My phone has the bootloader locked, the manufacturation date is 12w23 , and the bootloader unlock status allowed: NO
Is there anyway to unlock my bootloader?
Thanks a lot!

Maybe a guy with medusa box can do it, there is NO online service that can do it, so don't look. You could take out the sim lock on your official provider (might be cheap or expensive) and then unlock by Sony's official method since it'll say "allowed: yes", but even if you do, you probably don't even have fastboot enabled, so you also need to contact Sony and see if they can enable fastboot after you are done with the simlock

[Question]Unlocking Bootloader & TurboSIM

Hey folks, I've been nugging around the bootloader unlocking problem, since I own a Neo V which is locked, and the service menu in the phone says that the Bootloader cannot be unlocked. So I've read through some threads about this, and I wondered upon the idea, if I unlock my SIM lock(probably with TurboSIM, since thats the cheapest solution), would that enable me to unlock my bootloader, and start the real modifying of my phone?
What do you guys think? Worth's a try?

Both are unrelated but often confused. Unlocking for a different cellular network and unlocking bootloader are completely different sadly.

Sony Xperia Z1 Compact - Locked Bootloader ???

Hi XDA
I recently acquired a Sony Xperia Z1 Compact, but it seems that the bootloader cannot be unlocked (even after grabbing the code from Sony)
it says that the command isn't allowed, then I saw a post on a forum saying that not every bootloader can be unlocked.
I was wondering, since I have a unlockable* bootloader (which I assume there are ways to unlock it, because lets face it.. is there anything out there thats "locked" and hasn't been cracked into?
Anywho.
I have been to EVERY single "Phone repair / unlock" shop in my town, and none of them know what a bootloader is. So I decided to see if anyone here has managed to unlock their locked* bootloader.
If anyone can shed any light on this, it would be great.
Thank you.

It keeps saying I need to unlock the bootloader but it says when I try
"FAILED (remote: Command not allowed)"
This is what I mean.. I can't unlock my bootloader.
Unless I'm missing something?
Anyone?
Have you tried with SONY?
Perhaps the easier solution is to start from SONY itself....

Guys.. it says "Bootloader unlock allowed: No"
Which means I can't use an official way to unlock the bootloader, what I need to know is if theres a different way I can unlock the bootloader. By flashing firmware, a different bootloader or any special utility to unlock the bootloader. Thanks

Anyone able to shed light on this? I really don't wanna have to sell the phone due to the bootloader being locked..
Especially not after scoring 43,000 in Antutu
are there such thing as a custom FTF file I could flash with a locked bootloader?

Unlockable Bootloader - options?

After rooting my Z2 and backing up the TA partition, I've discovered that the bootloader is not unlockable (it's a Vodafone branded device).
Is there a nefarious way in which to bypass this? I understand that the whole point is to keep it locked, but it's an old enough device so I may have missed where it's possible.
Otherwise what are my options for an up-to-date custom rom? As indicated, I've already achieved root and have TWRP installed. I tried flashing Lineage via recovery but got an E: unknown command [log] error.
I'm in the same boat unfortunately. I bought a used phone that had Vodafone UK. It was marked as SIM-unlocked, and that seems to be true; the service info doesn't show any filled checkmarks nor counters in SIM lock information. However, bootloader seems to be locked forever - flashtool reports "Bootloader status : NOT_ROOTABLE" and phone's service menus also say that rooting status is "bootloader unlock allowed: no".
I wasn't even aware there are Sony phones that are not SIM-locked but are still boot-locked without any way to unlock.
I would really want to upgrade from Android 6 to at least 7 because there are some specific apps that work only from A7. Wondering if there is any custom ROM that would run on stock A6 kernel but with everything else from A7? It should be possible to install such a ROM even on a bootlocked device, right?
Since posting I've discovered some answers. The bad news is that, no, custom ROMs are limited without an unlocked bootloader.
The potentially good news is that you can pay for an aftermarket SIM unlock, which has the side effect of also allowing the bootloader to be unlocked.
I've not tried it myself, but do a search for "Sony cable unlock credits" for some leads.
Yea I also am stumbling upon this same news, in my city there are some shady areas so I will ask around and see if anyone is capable of doing it and will let you know.
So far my phone has bootloader locked, sim locked with 3 attempts left so I will work on unlocking those and then rooting the phone and digging deep after
Lets cross our fingers that somethings comes up
So far online , I find only old videos and outdated information, websites down and nothing else.
One thing is for sure, if your bootloader can be unlocked, you just go to sony official website and follow their instructions and its free and easy,
But if it says ""bootloader unlock allowed: no" then...lets see what can we do.
Hey I am willing to pay, why not if its going to unlock the bootloader 100%
