[Q] Bootloader unlock problem - Xperia Z3 Q&A, Help & Troubleshooting

Hello guys!
I'm trying to unlock bootloader of my Z3 the official way but i have a problem.
First my phone says "bootloader unlock allowed : no" and then when i try to unlock it it says "failed".
Here are pictures that will explain my problem.
Is there any way that i can unlock it?
Thank you in advance!

The bootloader unlock on your device is sadly not possible as far as I know. As long as it states "bootloader unlock allowed: no" it will always fail to unlock it.

No, if it says no, it cannot be unlocked. There is no way for it to be done. Endex

[Q] Would a Sim-unlock set the "Bootloader unlock allowed" to Yes??

Hello!
I have a question about unlocking!
If i unlock the Sim-lock on a smartphone (by a code), does this also set the bootloader settings from:
"Bootloader unlock allowed: No" => to: "Bootloader unlock allowed: Yes" ??
Thanks, regards,
Stefan
Try and see
You have nothing to lose from trying, if it works you have phone without Simlock nor bootloader lock and if it doesn't work you'd still have a Simlock-free phone. I don't even know why you haven't tried yet...
Bootloader and SIM locks have nothing to do with each other.
Thanks for the expressive one answer !?
I cannot try it, becaus the phone is not my phone, i want to buy the phone! So, if i could unlock the bootloader with a Sim-unlock,
then i buy the phone & buy the sim-unlock(code). If i could not unlock the bootloader, i am not interesting to buy this locked-phone!!
My consideration is: Buy a cheap locked-phone & unlock it by my self (+pay the unlock-code) OR buy a expensive unlocked-phone!!
... or don't pay for the damn unlock-code an hack the damn bootloader, so that i could change the "bootloader unlock allowed" to YES!

Stefan
"Bootloader and SIM locks have nothing to do with each other. "
... OK, i understand - Thanks!
If you sim unlock your phone you will be able to use any sim card, but unlocking your phone in that way does nothing to allow unsigned or non-officially signed bootloaders, recoveries, or roms to be loaded on the device in the same way that unlocking the bootloader does not sim unlock the phone.
OK, Thanks!! - this is a very important information for me!!

Unlock bootloader

Hi guys, I have this problem with my M2: A week ago I looked on the web for several methods of how to unlock the bootloader. The first step of all those methods was to check on the phone if it was possible to unlock it by introducing a code on the call dialer to get into some kind of "Secret menu". The result was always the same "Unlock bootloader: No". Instead of this I have tried with two or three different methods, however any of this worked. Do you know how to unlock the bootloader in this situation?
Please tell me if I wasn't clear enough.
You can't unlock it if it says No.
Sent from my D2303
Ok, I hope that somebody find a solution soon. Thanks for answering.
Wait, does it say "Bootloader unlock allowed: No" or "Bootloader unlocked: No"?
If it says "Bootloader unlocked: No" you can unlock it, if it says "Bootloader unlock allowed: No" you can unlock it only in Spain
Look what it says :/

It's impossible to unlock...
Is it simlocked? If it's simlocked to some network you are unable to unlock the bootloader. If you unlock the phone, you will be able to unlock the bootloader

I had several phones that were sim locked and I was unable to unlock the bootloader. After sim unlocking them I was able to unlock the bootloader. The same goes for the Xperia M2, it was locked on T-Mobile MK, after unlocking the phone I was able to unlock the bootloader.

So, I assume that if I flash a debranded firmware from Xperia M2 (My cellphone can't unlock Bootloader about the "[x]Newtork 10" is locked in SimLock) may unlock the bootloader without any troubles? Is that so? Or I'm mistaken?
If I'm correct, that'd be amazing, I'd like use other ways to personalize my phone but I can't 'cause of the stupid Bootloader xDD.
Thanks!

Unfornately yes it's true how DavidMKD sayd before you need to unlock you device before unlocking the bootloader i asked few friends and XDA members and they confirmed too so , unlock the phone than you can unlock the bootloader

Debranding basically removes all the bloatware that slow your phone down. You can't sim unlock with debranding, only with special code provided by some other sim unlock sites/ebay

Using the IMEI to get a code?

Exactly that. Try to enter it correctly because there is a limit on how many times you can enter to network unlock code. If it doesn't work on KitKat, downgrade it to 4.3 and enter the code. I had similar problem where I was unable to unlock on KK but on 4.3 worked fine.

Well, about that, I have a "plan", or, better said, a contract between the carrier and the cellphone, so, I must wait for two days to complete the "legal" contract. So, after that, I guess that I can unlock the device and then, unlock bootloader.
Thanks for everything!

[Q]Bootloader unlock allowed: no. how to unlock?

My XZ device can not unlock the bootloader:crying:
But no SIMLOCK!
please help me!
F8331 Device:crying:
Screenshots:crying:
(;_please help me:crying:
Enter developer option
Turn on Oem Unlocking
Then unlock your Bootloader
It's not Important Yes or No
Just Do It
You can't unlock the bootloader. Sim unlock and bootloader unlock are 2 different things. If you see Bootloader unlock allowed No... That means you can't unlock it. Quite simple really.

I opened the OEM lock in the developer settings! However, it shows that the boot loader can not be unlocked:crying: And I tried to unlock it ~ but failed
If it says no then it is impossible to unlock the bootloader.
SIM unlock is different, for that you need to speak to your network provider.

this is just incorrect. If it says 'bootloader unlock allowed: No' then you cannot unlock the bootloader. Nothing can change this setting
