[Q] Unlock Bootloader even if it's now allowed

My name is Dante, and i have the xperia M2 d2305, and it says Unlock Bootloader allowed: NO ,
And i have read that i change it by free or anything, my questions are :
1) What happens if i try it anyways ? does anyone know ? will it brick or bootloop or will it work ? i dont want to and i would prefer to dont take such a big risk.
And...
2) Is everyone totaly sure that i cant change it and unlock it ? i would really like to unlock it so i can install cm in the future (not so far future...).
Anyway, thanks to everyone and sorry for my english.
Greetings from Argentina.

You can ask your carrier to make your bootloader unlockable I guess

No, you can't, AFAIK only in Spain you can change Unlock Allowed: No to Yes if you don't have SIM lock.

but what if i try to unlock it anyway ? did anyone tried ? would i get a bootloop or something worse ?

It wont proceed. In most cases it is not allowed when the phone is carrier-locked. If your phone is sim free then you should ask you carrier to unlock it for you

Unlocking bootloader imposible

Well, hello to everyone. I bought Sony Xperia Z3 and bought code to unlock it for all sim cards and it works. When i visited Sony's site for unlocking bootloader i came across this post:
In your device, open the dialler and enter *#*#7378423#*#* to access the service menu.
Tap Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Well, my device cannot be unlocked because it says No..
so what can i do to unlock it?

What? Do you know what you are taking about..
Anyway, if the service menu says you cannot do it then it is impossible to unlock it.

Why unlock it? You will lose your DRM keys if you do..

For your device it is not allowed, so you can't unlock the bootloader.
/I've read some threads about trying to unlock the bl although service says "no" on other Devices like z Ultra:
It's not impossible to unlock the bl with official method if you know your device earlier had status allowed "yes".

its necessity if you want an aosp rom .....

Stock basted Roms on most Sony devices are pretty fast and solid in my opinion no need to really unlock unless your desperate for cm

So that's it? If the bootloader can't be unlocked officially, I'm stuck on Sony roms forever?
Wouldn't bother me so much but my Z3 has a horrible bug where it doesn't work with the bluetooth in my car without rebooting first every time. Was hoping to install CM12.

Could be a hardware fault the Bluetooth

Why did you get a Sony phone then

It's not that I have any major issues with Sony roms, I'd just like to be able to flash other stuff in the future, should I want to.
I'm still going to keep the Z3, such a nice phone, nothing else really comes close to it for me yet. Maybe the M9, but I just got the Z3 for £260 from o2 and had it network unlocked, probably have been looking at least double that for the HTC.

You can still root the device and customize it. Tools like the XPosed framework are great at modifying specific parts of the ROM.
But to confirm: you're stuck. You can't unlock Sony's unlockable bootloader. I've heard of people trying to unlock it, I've never heard of a successful case.
Enjoy the phone, it's among the best available right now (imho).

Hi,
-First you can't change it to yes
-Second You can't root your device for the time being cause you need an unlocked bootloader
-Third there's no way to unlock a bootloader unless you have "Unlocked allow yes"
-Fourth be polite next time and say at minimum "Hello" please

Assalam o alaikum!
I've found a software on YouTube to change bootloader status no to yes

I don't think so, we're talking about bootloader so it can f*cked up anytime I think it would be better to don't play with it if we're not sure.
This is just an advice, do what you want to do after that, I'm just giving my thought no need to follow it if you don't want to

What is the logic behind this?
I mean some devices are unlockable and some are not!
What this actually mean?

Well! Can i install custom recovery on locked bootloader?

Nope, you need to unlock the bootloader in order to flash anything.

So it simply means i can't flash any recovery,rom or root my device

That pretty much mean you can't do anything right now sorry bro

It means I've to sale out my device
And buy other brand like LG or HTC

Or exchange it against another unlockable one ?
I don't know, do as you like, sorry for you, just bad luck

http://bootloaderunlock.com/
I've found a video tutorial on YouTube with a link to download software to unlock the bootloader of devices those shows the status "Bootloader unlock allow:No"
Here is the video link

Beware a lot of fake videos are running through the Internet, I warn you, but as I said before do as you like.
If I were you I would not play with bootloader, either I change phone, or I wait for a locked bootloader tuto.

Did you try this? I found this video a while ago, decided not to try it

Why not to try it?

Okay now i decided to not to play with my z5 and change my device

Wise choice, still sorry for you mate

Thanks but this is definitely my last device from sony

This ain't Sony who's responsible, this is your provider.
I'm French I have a Z5 (no prenium no compact)
From Bouygues Télécom, and it ain't locked I'm actually rooted running a custom Rom everything is fine.
This is between you and your luck, you and your provider

Can't unlock bootloader Xperia Z3

I want to install a custom ROM and recovery on my Z3 but I can't find a way to unlock the bootloader. Even with the FlashTool it doesn't seems to work. I tried downgrading to an earlier version but everytime my phone gets bricked unless I use the last version available.
Thanks

Go to dialer. Type *#*#7378423#*#*
In service menu navigate to service info, configuration, and you will see a line that says "bootloader unlock available: yes" or "no"
If it says no then you will not be able to unlock the bootloader as it is factory locked to this state.
If it says yes then follow the Sony guide to bootloader unlocking Z3. They will email you the unlock code and details of how to proceed.

It says "no"... There's no way I can unlock it if it's written no ?

That's correct.
Unfortunately not all devices can be unlocked and there's no way to change that status.

Hi,
as reported in the official Sony page "If Bootloader unlock allowed says Yes, then you can continue with the next step (to unlock bootloader). If it says No, or if the status is missing, your device cannot be unlocked.".
It seems to be a problem of the carrier but if your carrier is Movistar you can give a look on this thread:
search on Google "Bootloader unlock allowed: No... SONY solve it, please!" (sorry but i can't post link)
