If you don't know what how to lock it on Nord 2, it is better not to write disinformation here.

<Moderator Edit>: Removed quoted post due to being deleted at poster's request.
No you right if you use your device, but he wrote in OnePlus Nord 2 theme, that's why I told you that you way to lock bootloader isn't applicable to rooted Nord 2 device.

There's a similar thread in general forum

Thanks for your advice. I think re-locking the device means, one must be familiar with all the tools and all so i think there is no need of screenshot and also it is very simple steps.
Hello... There's already a thread of this topic . http://forum.xda-developers.com/showthread.php?p=30731936

thanks for the DL link and info.
one more silly question, i have found that once the DRM keys are lost it is not possible to get back it again, so still is there any solution for it or not?
I really don't know, i think you can't get it back. When you requests unlock code from sony, you do it with your imei, so they have info for every phone that have unlocked bootloader and this is final. No getting back. I heard that bootloader unlocked with test point method can save your drm, but i'm not sure, better you search in general section and find more information. When i was searching to unlock my bootloader, i found out that is test point method bit aggressive and i didn't want to break my phone, so i done it with official method which is very safe.

UNLOCKING THE BOOTLOADER:
This may wipe your phone, so backup your stuff
• Go to Sony's dev site
• Request the unlock key and check your mail straight away. Email is quick these days.
• Open Flashtool on your computer (yes, the one you installed earlier)
• Click the "BLU" icon
• Follow the steps and enter your unlock key

Can't get Bootloader Unlock permission!!!

Hello everyone,
I applied for permission to unlock my RN3(kenzo) bootloader around 3 weeks back, and still haven't got any message from Xiaomi. I tried going on without it, but the MiFlash unlock tool can't verify my device (after 50% progress it displays this message). Now I can't even seem to apply again for this permission. This is what happens :
I click the 'Unlock Now' button on this page:
http://en.miui.com/unlock/
And instead of applying for unlock permission page it takes me to this page :
http://en.miui.com/unlock/download_en.html
Where I can only download the MiFlash tool.
I have been trying this for days now but it can't seem to work.
Utterly frustrated, I have came to seek help on this forum. Hope you guys can help me get over this hurdle.
Regards.

Yeah it is. I previously used a MOTO X 2014 (MOTO G 2013 before that) and unlocking bootloader was a breeze there. Took a maximum of 5 mins, and I thought it'd be same for this device. But, oh boy!!! Xiaomi really test your patience.
Anyways thanks a lot for this. Will give it a go too.

easiest, fastest and safest method (works for kenzo/kate):
prerequisite:
MIUI 8 Global Developer ROM 6.9.29
ZCX TWRP
Mi Flash 6.8.30
1) Download 6.9.29 fastboot MIUI ROM
2) Extract and replace recovery.img (in images folder) with ZCX TWRP.
3) Flash using Mi Flash (in EDL mode)
4) After finished flashing process unplug and press [volume up]+[power] until Mi logo shows up then release buttons and it boots to TWRP
5) Backup, reboot to system and accept that TWRP disable/overwrite standard recovery
6) Boot to MIUI. (important step)
7) Finished!!
Now you have access to TWRP and can flash custom roms and kernels with locked bootloader.
No need to unlock bootloader anymore!

Maybe this will help you. I was having a lot of trouble too unlocking the bootloader as mi flas tool would never go past 50%. What I did was :
1) Apllied for unlock permission (that you've already done).
2) Downloaded mi flash tool and tried unlocking with it(that failed obviously)
3) Logged into Mi Cloud at i.mi.com
4) Checked connected devices, there were two there. You gotta Delete the one that's not Redmi Note 3, and make sure redmi note 3 is online.
5) Now you go to Settings>Additional Settings >Developer Options >Mi unlock status, and bind the account there for unlocking.
6) Goto i.mi.com and click on someting like 'Find my phone'. It'll be there.
7) Now if it can find your phone and tell its location, then you're good to go. (This step is important I guess)
8) Go ahead and try unlocking your phone with Mi flashtool.
I hope this works for you(worked for me though).
If you can't unlock via this method there are a few unofficial unlocking methods or you could contact Xiaomi and they will correct your data on their server side and you should be good to go.

For me (and a lot of others) it was impossible to bind it, server always returned an error and asked to try again later...I unlocked unofficially and I'm a happy user of RR 5.7.4

Well you're right doing it. All this bootloader unlock charade is getting ridiculous now. I mean Xiaomi should learn from Motorola, their phones too come with locked bootloaders and unlocking them is a breeze(unless you use a carrier branded one).
Maybe it was just a good day for me that my BL got unlocked
Same here unlock always redirect to download page mi unlock tools or what ever ****!? Cant apply permission... Try another account, not help.

If you only want to relocked your bootloader just use the HWOTA8_Mate 10 tool from the link bellow.
download the tool > go to lock directory > use relock.bat
you'll need to provide your bootloader unlock code to re-locked it.

I think you are not having proper mate 10 pro windows drivers. Try following the HWOTA_mate10 guide about preparation, there is a registry fix and you should uninstall HiCare for proper device recognition

Hi, i just started thinking about that, just to be sure since i did not get mtp folder in my computer anymore(win 10)
i switched to my laptop win 8.1,
installed the adb driver manually as adb composite interface in normal mtp\debug phone on.
in fastboot the driver said adb sooner single interface
and then when i am supposed to switch inn to the stock recovery modded with adb support,
i get 3 devies with yellow ! in device manager:
1. huawei- device properties and details then choose bus reported device description: huawei
2. unknown device: - device properties and details then choose bus reported device description: adb interface
3. unknown device: - device properties and details then choose bus reported device description: hdb interface
what should i set these to manually?
i am trying to use "flash update" in HWOTA_mate10 guide and i am on step D run ota.
supposed to switch from fastboot to recovery then the script waits for adb connection
Did you disable oem unlocking in developer options?

Bootloader Unlock not possible - but eRecovery working
@ante0
I have Mate 10 BLA-L09c432 and installed latest Firmware 8.0.0.157 since two days. I updated with official OTA.
Before I had 8.0.0.137 → on that Firmware I read the Bootloader Unlock Code with DC Unlocker → and I got a new Unlock Code.
The originial Unlock Code did not work anymore (Phone was from a friend of mine and bricked and I restored it by FunkyHuawei - and bought it).
I unlocked the Bootloader with the new Code (read by DC) and it worked.
Two days ago I decided to update with OTA. I reflashed the original recovery_ramdisk and ramdisk.img. Update was succesful.
→ I tried to relock the Bootloader (because I am thinking about to sell the phone) → and it does not work! Not with the originial Code, not with the new Code (read on b137)
I did nothing wrong, because this year I unlocked about 40 devices (because I am helping to repair bricked phones from Users of Android Hilfe de) and I know very well how to do. (OEM Unlock enabled, ADB Debugging and USB Debugging enabled, HiSuite HDB disabled, HiSuite on PC closed, ADB and Fastboot working....)
Code:
fastboot oem relock UNLOCKCODE
does not work
But I have no idea yet how to relock the Loader I will try once more - but perhaps you or someone has an idea?
So perhaps I should just be happy to have a unlocked Phone and keep it instead of selling it....
Everything else is working.
And I found out some interesting point → seems Huawei started to bring the Feature of eRecovery even to European Versions of his Phones (from a certain firmware version)
I booted to Huawei eRecovery and "Download latest version and Recovery" is running without FunkyHuawei

I have Mate 10 BLA-L09c432 and installed latest Firmware 8.0.0.157 since two days. I updated with official OTA.
Before I had 8.0.0.137 → on that Firmware I read the Bootloader Unlock Code with DC Unlocker → and I got a new Unlock Code.
The originial Unlock Code did not work anymore (Phone was from a friend of mine and bricked and I restored it by FunkyHuawei - and bought it).
I unlocked the Bootloader with the new Code (read by DC) and it worked.
Two days ago I decided to update with OTA. I reflashed the original recovery_ramdisk and ramdisk.img. Update was succesful.
→ I tried to relock the Bootloader (because I am thinking about to sell the phone) → and it does not work! Not with the originial Code, not with the new Code (read on b137)
I did nothing wrong, because this year I unlocked about 40 devices (because I am helping to repair bricked phones from Users of Android Hilfe de) and I know very well how to do. (OEM Unlock enabled, ADB Debugging and USB Debugging enabled, HiSuite HDB disabled, HiSuite on PC closed, ADB and Fastboot working....)
does not work
But I have no idea yet how to relock the Loader I will try once more - but perhaps you or someone has an idea?
So perhaps I should just be happy to have a unlocked Phone and keep it instead of selling it....
Everything else is working.
And I found out some interesting point → seems Huawei started to bring the Feature of eRecovery even to European Versions of his Phones (from a certain firmware version)
I booted to Huawei eRecovery and "Download latest version and Recovery" is running without FunkyHuawei

Use the DLOAD method with the B150 firmware from androidhost.ru, that should lock (not relock) it.

Then you can use B150 to downgrade with DLOAD method. That should reset the phone and lock the bootloader, to fabric condition.

Will this work on Mi 8 Lite ?
Yes this method works on all xiaomi devices
Hello!
Some people claim that locking up the bootloader on newer Xiaomi devices could brick the phone.
Does this information proceed?
Has anyone tested?

This video don´t show how to lock bootloader so the essential part is missed, maybe the guy is talking about but most of users won´t understand what he says and is not reflected on the options that he is using.
If you want to lock bootloader using MiFlashTool then at time to flash a stock rom you have to check on "Clean All and Lock" option down at the right in the tool.
Locking bootloader can´t never brick device by itself, the problem is that some users tried to do it using a custom rom, a custom recovery, rooted or with a cross-firmware that was not released originally in the device and happened that after device was locked again then refuses to boot to android system so bootloader detects that some partition/s was/were altered.
If you only unlocked bootloader and you are using all stock and non rooted you can relock it without need of use mi flash but using only the typical fastboot command
Code:
fastboot oem lock
then check if it was correct with
Code:
fastboot oem device-info
BUT never try to lock it of this way if some non-stock file was flashed and currently using on your device be custom rom, custom recovery, root, logo, custom kernel, etc.

Thank you, bro!
All my doubts are clear now!
you cant lock bootloader if you firmware was originally chinese and you have changed to global..
if your firmware was global and you unlocked , yes you can lock it again using flashtool and oficial GLOBAL fastboot rom,developer or stable..:good:
Hello, I've been trying to unlock my Mi8 Lite for a while (bootloader) but it is always stuck at 50% on MiUnlock, I've tried multiple drivers and disabling driver signature in Windows 10. It never gets beyond that point and always shows a '-1' error. Did anyone encounter this or better yet solved it? I've searched many times on Google and Youtube but with no success.
I had requested an unlock from Xiaomi and disabled all my other devices from my account.
Any help would be appreciated as this has become unnecessarily complicated, Thanks!

Check again if it´s correctly binded your MiAccount on Developer Options and try with other MiUnlock version.

Yes, I had the same issue and got it solved by using Mi Unlock on another PC. My main PC is using AMD Ryzen 2700 CPU, my laptop Intel Core i7-4712HQ. Wasted like 2 hours on my PC, while it worked first try on my laptop. Please note, the software told me to now wait 360 hours - it didn't unlock right away (this looks like expected behavior).

You can flash fastboot ROM and set to clean all and lock, then the bootloader will be locked by a script from fastboot ROM

Once i unlocked the bootloader, after i set a new password and fp it just kept saying that i need to enter my password every 0 hours. Tbh it did warn me when i accepted the oem unlocking that security features like fp, face recognision and find device will be disabled. So here is the question, is there any way at all to lock the bootloader without factory resetting?
P.S. : I have flashed twrp and miui 12, because i destroyed the miui 11 [:
