So, i thought my xperia z3 has a locked bootloader, since it was locked in OrangeRO. I upgraded my firmware through flashtool to get rid of Orange's bloatware. A couple of days after, i entered in configuration and saw that the bootloader was unlocked. I was surprised, then i wanted to root it and flash CM eventually. But I hard reseted the phone accidentally.
Now I can't unlock the bootloader anymore.
-not with sony's official way
-not with flashtool
What happened, and how can I unlock the BL again?
You mean at the begining it was saying: Bootloader unlocked: Yes
And after the reset now it is saying; Bootloader unlock allowed: No
?
At least this I unrstand from what you've wrote.

Hi,
I am a beginner. I reag this http://forum.xda-developers.com/showthread.php?t=2743694
I just bought an Xperia phone M2. It is block in the Vodafone network.
"Bootloader unlock not allowed"
What to do, what are the steps to use it on another network?
Thank you,
There is no way around it I am afraid. Your bootloader cannot be unlocked and that's it. I am in the same boat as you, except mine is from T-mobile. The only thing that we can hope for is that someone will find a way to root the Xperia's M2 stock 4.3.2 rom without flashing a custom kernel or recovery. Hopefully there will be custom roms based on stock in future, but we can forget about roms like CM, Paranoid etc.
Oh and btw, simlock is not the same thing as perma locked bootloader. You can remove the simlock, but that won't change the "Bootloader unlock allowed:" to "Yes". This was already confirmed in the Xperia SP forums. There were rumors that custom mobile shops can change the bootloader status, but we are yet to see any confirmation about this. Also, even if they can do it, it is still questionable if the fastboot mode will be there at all.
Thancs!
Here is a way to unlock your M2 http://www.xperiacodes.com/shop/unlock-sony-xperia/unlock-sony-xperia-m2/

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!
I did unlocked bootloader for my xzs by offical way. First time it failed but successful on second time.
My device now can do anything same a device Unlock already, flash anything bla bla.
But i really confuse when i'm check on Service Menu. My device still show on Rooting status: Bootloader Unlock Allowed: Yes (i read from some forum this mean Bootloader still LOCK)
And on Service test: FIDO_KEYS: provision failed (i known drm keys already gone)
Anyone can tell me actually my device completely unlock or not? Because i want to relock before sale it for someone else but don't wanna loses the camera anymore after relock.
Thank you so much
Hello. I have a Softbank 601SO Xperia XZ (which I sim unlocked as recently I changed to Y Mobile) and am wondering what I am able to do with this device. I can't change the status from "Bootloader unlock allowed: No" and when trying to downgrade Android from 7.0 to 6.0 by flashing it, it seemed to be softbricked so I had to factory reset it using Xperia Companion (and it reset it back to 7.0). Does anyone have any experience rooting this phone with the bootloader locked or was anyone able to change the unlockable status to Yes?
Thanks!

### There is no way, because Bootloader unlock allowed is no. ###

I see, I thought that some people have rooted their phones successfully without unlocking the bootloader. I've also seen some people saying they successfully changed the unlockable bootloader status from no to yes by sim unlocking or downgrading their OS. Maybe these are rare cases...

Ya may be, after Marshmallow update you need to root by flashing zip Su/magisk and for that recovery is required.
Yeah, if it can't be brought back to a previous version it's probably not going to work...it's sort of annoying having a phone that belongs to you and is carrier locked even though you no longer have any connection with that carrier!
So i received a american pixel 4 xl with a locked bootloader. imei starting with 35
i was able to unlock the bootloader here is the steps i took, note im in Australia.
Full OTA Images for Nexus and Pixel Devices | Google Play services | Google for Developers
developers.google.com
the firmware on the device was american,
i flashed my countrys firmware (australian) optus/telstra/vodaphone etc
use adb side load *firmware.zip*
factory reset , booted device on with australian sim,
and boom oem was available ,
(last step is to adb reboot bootloader,
and ./fastboot flashing unlock and you will see a message on pixel.
intially with the Original firmware on the device it would not unlock.. i tried factory reset
/ fastboot flashing unlock etc and it would not work...
anyhoo i have not seen anything on here suggested flashing another firmware origin so i thought this might help those with locked at&t / verison carriers, intially it was GREYED OUT AND SAID contact carrier or connect to the internet.
Hope this helps someone ! as all the forums ive swiped thru have said this is not do-able, lol turns out it is.

The firmware does not determine whether the bootloader is unlockable.
When the device connects to the Internet, it checks its IMEI against a whitelist on Google's servers. If it has been authorized for bootloader unlock, OEM Unlocking will become available.
If it doesn't, it's likely that you have a locked variant.

What if it is already unlocked and I want to relock it? I flashed stock firmware, the bootloader is still unlocked but now I can't lock it again because the option is greyed out.

The OEM Unlocking toggle does not lock or unlock the bootloader itself. It simply allows you to unlock the bootloader when enabled.
If you want to relock your bootloader, you do this via ADB while in bootloader mode: fastboot flashing lock

For some reason I couldn't get into fastboot mode, "adb reboot bootloader" would just restart my device. If I booted into recovery, the "reboot into bootloader" option would just start up the phone. But I eventually found out I can lock the bootloader in download mode
