For people like me who can't unlock their bootloader on the Sony Xperia S because the bootloader unlock option is set to no i.e. the official method below shows no:-
Open the dialer from your device and dial “*#*#7378423#*#*”.
Then, go to “Service info -> Configuration -> Rooting Status”. If the “Bootloader unlock allowed” option is there is perfect and you can complete the operation. If not, or if the status is missing, your device cannot be unlocked.
Is there another way to unlock the bootloader at all?
I realise this will invalidate any warranty but would really like to flash cyanogenmod 9.1 onto it as its so much faster and usable than the stock rom.
Many thanks in advance
Also looking for a way around this... Although my nozomi is unlockable, it fails to unlock with every tool out there...

Same as that.. I thought I'd seen a paid unlocking service somewhere...
+1
I think
S2tool works but sure it's a paid service or try wotanclient
As for those who get a No in status, that's the only option!
For those whose status says Yes,you can unlock officially from Sony website

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

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!
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?

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

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 everyone. Does anyone know how to unlock the bootloader for D2206? I am running Kitkat 4.4.4. I tried using the Sony method but it says bootloader unlock allowed: no. Does that mean it's impossible to unlock the bootloader for this variant?
Thanks in advance.
Unfortunately nobody has figured out how to do it yet.
I have a D2206 from Wind Mobile (Canada) and I have been unsuccessful in unlocking the boot loader or rooting it. All the guides on this forum are for other models of the E3 because apparently very few people have the D2206 so nobody has spent any effort on it.
With only 4 gb storage and only 1.7gb free after all the bloatware, this thing is a useless paper weight unless I can figure out how to install marshmallow in order to use my sd card as internal storage.
If anyone figures out how to install marshmallow on the D2206 please let me know!
To this day, did someone figured it out how to unlock?
D2206 with bootloader unlock allowed: no
Really want to give this phone a life again

I never had to face this situation, but I have checked around and I found that there is a tool which let's you unlock your phone (SIM and unlock booloader status) which you can check here:
https://forum.xda-developers.com/t/bootloader-unlock-allowed-no-to-yes-is-possible.4044091/
The only pitchfall is that you have to pay for using it.
Otherwise you may contact Sony to get a solution. I guess that they allow you to send it to them and they can unlock it for you if SIM is unlocked, according to this page (it is written in Spanish).
I hope this can be helpful to you.
Regards.
Bootloader Unlock Allowed No to Yes is now finally possible
Discovered by MrCooper95
QUICK STORY OF HOW IT HAPPENED
For years, members of Xperia users thought that if you had a SIM locked Xperia phone, you would never able to unlock the bootloader even after you get it SIM unlocked, the Bootloader Unlocked Allowed will still remain "No".
You would have to buy a factory SIM unlocked phone instead.
For a good price, I've bought a used SIM locked Xperia 1 that has been hardlocked ( 0 unlock attempts left )
The previous owner tried to get it SIM unlocked, but the codes he used were incorrect and went over the unlock attempt limit, causing a SIM hard lock. He did not mention this when he put it up for sale.
Anyway, I looked around the internet and the found a program called QUnlock. ( S1 Network Unlock Tool )
The S1 Network Unlock Tool is free to download but you have to pay credit in order to work. About £20 ( you pay via mobile phone repair shop websites ) and then they will email you a username and password for you to connect to the S1 server in the unlock tool.
So I connected the Xperia 1 via flash mode in S1 Network Unlock Tool and it worked. My phone is now SIM unlocked after being hardlocked.
After booting up the phone. I went into service menu to ensure that it is free from SIM hardlock, the tool worked successfully.
but I also checked the bootloader status and it changed to "Yes".
I was suprised and amazed at the same time after all these years, we were told that changing the bootloader status No to Yes is impossible, even people told us that a permanent hard locked Xperia phone can never be reset.

QUESTIONS AND ANSWERS
Q. What is the S1 Unlock Tool and what does it exactly do?
The S1 Network Unlock Tool is used by professional mobile phone repair shops and it has been around for a long time. This tool is created and only works for Xperia phones.
It is also available to be downloaded for anyone who can do it themselves at home with just a USB Cable.
This tool is used primarily to reverse a Xperia phone with a permanent SIM hard lock ( 0 unlock attempts left ) and changes it SIM unlocked.
It can be used as a normal SIM unlocking service.
However nobody really knew, that this tool can also change your bootloader status from "No" to "Yes".

IMPORTANT INFORMATION
You should always back up your Trim Area Partition (TA.img) if your Sony phone has a backup exploit.
After you have unlocked the phone using the tool, a sign file ( backup ) is created in the tool folder.
Don't delete it, keep it incase anything goes wrong. ( See warning below )
WARNINGThere are reports from some users encountering a no SIM card service / detection after they have used the tool. It is evidently related ( so far ) with some of the Japanese Xperia models.
Japanese SO Xperia model ( Docomo / SoftBank )
Japanese SOV Xperia model ( KDDI )
If this happens, restore the backup and get your refund or try flashing a custom ROM or another firmware ( only if it's safe to do so for Japanese Xperia models )

DISCLAIMER
I will not be responsible for any actions that you make. I am informing you that the S1 Network Unlock Tool can have consequences as it is not fully documented yet.
Please reply back with your Xperia and its model number if you have successfully unlocked your bootloader.
I will keep the thread updated, best of luck.

Great news and glad to help you out, I wasn't so sure if this tool will only work on a SIM locked phone to unlock the bootloader. But you confirmed that it works in SIM unlocked state, so that's some good news.

hi, any idea this will work on Docomo Xperia XZ / AU Xperia X Performance ? And did you paid 23 pounds to unlock a device ?
I did pay. You can download the software anytime, however you need a valid username and password to start the process. That's what you buy from the website. Got the the information within 24 hours. Windows thinks it's virus. It's not. Just temporarily disable defender for the download folder
As for whether or not it will work for your device:.I think it would. At least that's the impression I got when I emailed customer support. No guarantees from me, however :laugh:

I've got the Japanese model of the Xperia X Compact, with bootloader set to "No" in the service menu. Your method totally worked, after buying the item you linked I was able to unlock the phone using the S1 tool. Bootloader unlocked now shows "Yes". Thanks!
Okay so after bootloader unlock says yes is it still unlockable though someone tried? I have been out of game though I have unlocked a few Xperia Z devices in past and as I recall the method was to enter your IMEI on official bootloader unlock page and they were to send you a code or smth for adb might be mixing up because I think my LG's had same method so my question is after entering imei on sony site they allow it automatically?
