Nubia z11 Bootloader locked?

Hi,
is anybody here able to confirm whether the bootloader of the nubia z11 is locked or unlocked or at least unlockable?
I saw an ROM with a custom kernel so I assume it is unlockable?
Greetings and thanks

Hi
My phone arrived with the bootloader blocked, this can be seen running:
(reboot in bootloader mode, install android adb drivers then
fastboot oem device-info
DEVICE-UNLOCKED: false
To unlock my bootloader update to the Chinese ROM STOCK that has Android 7.1.1, enable the debugging options and in the same options appears PERMIT OEM UNLOCK, after enabling this option I was able to unlock the bootloader using:
Fastboot oem unlock
Now my bootloader is unlocked, since Android 6 I did not find a method

can you give me the link to the cinese rom? i'm unable to find it...

my android version is 7.1.1 and i would to install custom rom (for sure a rom with no google services ...)
i know for sure that i have to flash twrp , but before this i have to unlock the bootloader, and this is MY PROBLEM
it is 3 hours i'm looking for answers but can't find anything good

U dont need to downgrade, adb fastboot works with Nubia Z11. Make sure you download latest zte driver for your windows/mac os, only after that you'll be able to unlock it.

thx for your reading
but .. i found how to unlock the bootloader ..
the key point is that when you click on "allow oem unlock", the toggle becomes green but don't stay green if you're going out and re-enter dev options !
you have to click on the line and not on the toggle itself, and then you have to enter your pin !
then go back to bootloader and i have to type "fastboot oem unlock-go "
and voila !

In my case allow oem unlock 'toggle' worked normally, it asked for the pin as soon as i tap it and it stayed green after re-enterring in dev option.

Change from Chinese rom to global rom.

Hi there I have the chance to get two of these good smartphones in China for a good price. The problem is that they have the Chinese rom on it and my parents need the italian language. Will it be possible to flash the global rom or just add the italian language?
Thanks.

Based on my experience b4 unlocking 5A, the only way you can switch from China to Global is to flash it via test point. Unless you've unlocked the phone, you could flash it via fastboot. Is your 5A unlocked yet?

Yep, that's all you need to do. After an unlock, you do have the option to relock your bootloader (which maybe you're already familiar with). The guide is on the miui forums. Good luck!

Update options not listed in config, and no OEM unlock listed in Dev Options

The title pretty much describe the whole issue: I get a persistent notification that there's an OTA update to install, but touching the notification does nothing.
There seem to be no way of manually installing it either, because there is no update option listed in the configuration.
Can't unlock the bootloader either, because there is no OEM unlock listed in the dev tools.
I've never seen anything like this. Spent days researching, but found nothing. So here I'm hoping someone might have a clue about how to enable updates and OEM unlock in a situation like this.
Any help is appreciated.
This phone is a Xiaomi Mi A2 Lite model M1805D1SG, running Android 8.1 (OPM 1.171019.019.V9.6.6.0ODLMIFF)

for unlocking the bootloader you have to use ADB tools. you can't just unlock it in developer setting.
for your problem i would recommend you too check the forums on how to unlock the bootloader with adb and then grab the latest official A2 lite rom (10.0.40. or something i guess) and flash it with the MiFlashTool.
this procedure will upgrade your device without any loss of data.
I'm telling you this because that's how i update my device (which is rooted and kernel modified) with no problems.

True. We usually need to run 'fastboot oem unlock' to actually unlock the bootloader. Problem is, the command needs one to enable OEM unlocking in the developer options beforehand, otherwise it fails. And I dont have any means to enable OEM unlocking in the dev options, because it is not listed at all!
And without that I'm unable of doing any flashing.
The only report I found regarding a missing an OEM unlock option in the dev tools concern Samsung S9. Apparently one needs to wait 7 days for it to appear. But such a thing is unheard of concerning a Xiaomi phone.

I'm on 9.6.11.0 version and it's there. You're on 9.6.6.0 version. Maybe there's someone who had experience with 9.6.6.0 and OEM unlocking but if not there's always the option to do an OTA update to a newer firmware version.
Just don't update to a 10.x.x.x version (Pie) if you want to keep Oreo

Can't do an OTA update either. Check closely: along with OEM unlock, there is no system update option.

Maybe global ver and CN ver X80 PRO is not unlockable

When you said the method that worked for your x70 doesn't work for your x80, what do you mean by doesn't work?
Did the unlock command return OKAY and then it was still locked?
Or did it fail with some error message? If so, what's the error you're getting?

no but in KR carrier , we can not use VoLTE becasue there are no toggle.
so we have to unlock bootlader, root, and make VoLTE toggle with prop
that is why we have to unlock BL

mobile network setting has no option of VoLTE,

The device is VoLTE capable, but the VoLTE and WiFi Calling features only appear in the Mobile Networks/SIM settings if provisioned by your carrier's SIM card. Not all carriers will provision VoLTE for Vivo phones. In the United States T-Mobile does, but not some of the other carriers. In Canada, none of the carriers will provision VoLTE for Vivo phones, so you have to force VoLTE by unlocking, rooting, and editing to make the toggles appear in settings.

At least I could unlock global X80 Pro.
You can use this Android 12 rollback ZIP to downgrade fw to "2022-04-01" patch level.
For global X80 Pro, I had to update to 13 Beta first, then reboot to recovery to install rollback zip.
