Relock bootloader for account bound

Hi guys. I would like to know a thing:
I have bought a Mi 8 already unlocked from a shop. If I want to relock the bootloader again and bound my account to it, for future unlocks in case of wrong flash with Mi Flash (default flash mode is: "clean all and relock", that I can also omit to see for error), can I flash China without incurring in a brick? Because the phone will be delivered to me with Global Rom (that I know generate a brick with relocked bootloader).
Thanks to who will answer me.

I have the same question... It's possible change the account used for the bootloader unlock?

Without any other method to do this, we can only relock bootloader and follow the common way to unlock it with own account.

I purchased a Xiaomi mi 8 with unlocked bootloader without notice from the reseller. The outcome when I updated with miflash was a bricked phone. When I tried to use miunlock I saw a message that my phone is not bound to this account.

Mhh... Seems you have used the third option of Mi Flash (clean all and relock).
Have you tried to relock bootloader with China ROM or Global ROM?

Nothing seems to work. I can change Roms using adb sideload but the problem is that always is a bootloop.

I am using xiaomiadb.exe . You boot in recovery mode and then you drag and drop the rom over xiaomiadb. Pc suit sees the version. I have managed this way to change many roms, but the main problem is the boot loop.

Yes, I have tried everything I could think of. I am afraid that the only solution is to use Mi unlock, but I can't to that because the reseller send me the phone with unlocked bootloader. The program checks at the begging if I have permissions, then checks if the phone is a Mi 8, it passes that test too, but the message I get then is that this phone is not bound to this account.

I have asked Xiaomi Global service about that. They don't offer support. They don't recognize the Chinese e-shops as authorized resellers. And I suppose that a phone can't be bound to two accounts. The only thing I can say for sure is that the global version has a red label on the box and the manual is in English. Watch the video. https://www.youtube.com/watch?v=4Nx-jjTVh_8&t=107s

So it can't be possible to flash anything (also China, that was the born ROM of this phone) with option "Clean all and relock" of Mi Flash, without incurring in a bootloop?

The fact is that you can bound the phone to every account, if you can boot it with locked bootloader.
But if this can't be done, developer options menu will show you that bootloader is already unlocked, without possibility of bound your own account.

Oh wait, you can't use mi flash because your account it's not authorized for EDL.
Now I have understand because you can't relock bootloader. ?

When miunlock starts it checks if I have permission for EDL. It passes the test. But then it says that my phone is not bound to my account. The bootloader was unlocked so I suppose someone has bound my phone with his account.

Ok, so you can't use Mi Flash.
Now it's all clear.
Thanks for your explanation. ?

I'm having an idea ... My device is about to arrive. It will be a Chinese variant with bootloader unlocked by the store for installation of a global ROM. So if I flashed a Chinese ROM again, I could re-block the bootloader, correct? So I will boot the phone with the blocked bootloader in the Chinese ROM and I can associate my account and unlock the bootloader again, only this time with my own account. Would it work?
Sorry for my english, I'm using the Google Tradutor.

The problem is that you need to bound your account to your Mi 8, otherwise you can't use Mi Flash to relock your phone.
And you also can't lock it by fastboot, because this operation delete recovery and system partitions, generating a total brick.
Unfortunately my current Mi Max 2 was one of these unlucky phones, and I have learn lesson myself.

The best thing that you can do is:
Use last version of Mi PC Suite 3 to flash global and twrp to flash custom, and if you need to return on global from twrp, just flash original Xiaomi recovery and reuse Mi PC Suite 3.

Υοu're welcome. It's my first ever Xiaomi but I think that for a while because it's a new phone of the market we must leave it untouched for a while. I mean rooting, custom roms, e.t.c.

I couldn't say for definite, but you probably could unlock it by entering EDL mode via the test point method. But it will need an authorised account to do it. There's a Russian guy, whose contact details you'll find in these forums, that will do it remotely, or you can try s-unlock, either option will cost about the same.
Sounds like the only other option would be a service centre.

i will give it a try.btw who is that guy.i cant find him.Pm pls

Strange MI Unlock error | BL locked and system destroyed

Hi Guys,
Everything went wrong today. At the end i went to the point where i myself locked bootloader with fastboot. Want to unlock it again but this strange error appeared:
https://imgur.com/qBNM4ah
Does anyone know what this means? Phone is locked, can only go into fastboot.

Same here. My dumbass thought it would be a good idea to lock the bootloader (don't ask why because I don't even know the answer). System is destroyed and can only boot to fastboot. No Mi ID associated with it.

system destroyed happens when you lock bootloader on Chines device with global ROM. You get it when you trying to boot in system?

For EDL flash you need xiaomi authorized account, there is rumors that some Indians make EDL flash with remote connection and their authorized account for 12$. Try to search in google or if you have a xiaomi seller or official repair in your home town, check there how much it will cost you.
You sure you have a global version? Were you bought the phone? Was it with locked or unlocked bootloader and what ROM was on it? Because some sellers, mostly on aliexpress and similar, just unlock bootloader on Chines devices, flash a global ROM and call it global version.

From the image attached, it looks like someone used the Find Device feature and activated Lost Mode. Is the Mi account number shown yours?

K20 PRO the system has been destroyed, help-me

I have one K20 PRO, when i turn on show "the system has been destroyed", this message show after flashed one global rom with box "flash all and lock" checked.
The bootloader is locked, and i tried flash stock rom on EDL Mode with MI Flash but i dont have one authorized account.
Help me please.

I guess you should try unlocking the Bootloader again...It takes couple of days though. With the Corona virus being a thing in China it might take you a century to get a response, that is, if you ever receive one.

If the phone is bound to your own Mi account and you had already unlocked the bootloader yourself before, then you should be able to unlock the bootloader again, then flash an official ROM WITHOUT locking the bootloader.
If you bought the phone with the bootloader unlocked and you've never bound it to your own Mi account, then EDL flashing with an authorised account is the only way. The problem lately is that people are now finding it hard to find someone with an authorised account to do the EDL flash. If you live somewhere near an authorised Xiaomi service centre, then you could plead with them to flash it.

Xiaomi Mi 9T Pro Bootlooder locked

Hi Guys,
I purchsed Xiaomi Mi 9T Pro from Aliexpress with a Global Rom version but the device is a Chinese version.
The seller had to install global firmware and assosiate my device to other Mi account.
The current situation is my bootloader is locked and I can not use the Mi officially to unlock my device.
I tried to contact to the seller, but he can not assist me (they don't know the Mi account access details to release my device).
Duo to that, I tried looking the internet and found this forum. I have a good technic skill so I start tested all the suggestion the forum has to offer.
First I tried ADB and Fastboot, both are failed with the error - FAILED (remote: Token Verify Failed, Reboot the device)
I also tried miflash but he's requesting Mi account that I dont have the device their. I tried to flash a new fastboot but no success.
I really dont know what else to try, I hope someone here can spred some light on my issue from stoping my device to use as doorstops.
Thank you,
Noy

The bootloader cannot be locked to a Chinese device with a Global rom.
There is no Chinese Mi 9 t pro, the Chinese version is the K20 pro.
What is the phone model (my phone/characteristics/model)?

The device stuck on "Main Menu" MIUI Recovery 5.0 so I can not verified the phone model, but according to the seller page the model is: M1903F11A
https://www.aliexpress.com/item/33016509936.html?spm=a2g0o.order_list.order_list_main.61.21ef180253I770
I also tried to use MTK to unlocked the bootloader but I had no success to get the device into a brom mode. I can not trun the phone off, Vol+ & Vol- not works.
Is there any difference between the Mi 9 t pro and the K20 pro?

According to the model number, it is a K20 pro.
Chinese device so the bootloader is locked but with a Chinese rom since this is not possible with a global rom.
Same device except less 4G bands for the K20.

If the device is linked to an account that is not yours, nothing to do.
Is it a new or used device?
Check with the seller or send the phone back to him.

The device was new when I purchased it, the seller said there is no warranty on the device and he can not do anything about it. they used outsource company to do the installation of the Global ROM.
Surely there is a way to bypass Xiaomi locked on the bootloader. the Kernel can be overwrite somehow. just need to find the right way.

And you still don't understand that there can't be a Global rom on this model with the bootloader locked.

What you are saying now is inconsistent with your original post.
A long story to get to 'lock with fastboot'.

I'm sorry if there was a misunderstanding, here is the long story:
In 2019 I got this device from Aliexpress with a Global Rom version but the device is a Chinese version.
The phone was in English, working well with Google Play, and there was no issues with it.
In few months ago I wanted to start using Google Pay and my credit card was not approved for some reason, I contact google suppport and one of thier questions was "Have you unlocked your bootloader, rooted your device, or installed a custom ROM?"
So I started to google it, I find that my bootloader is unlocked, so I thought that I will need to lock it to be able using the Google pay service. what was found a terrible mistake.
First I understand that the only legal way to unlock it was using the Xiaomi official Mi program to unlock it. what I was found that I need Mi account with a registered device on it. my device is registered on some Chinese guy that I dont know so basically he's the legal owner of my device. so I start to look for an alternative solutions.
In my knolage with programs, I can handle with complex solutions to bypass this issue. but none of my trying wasn't succeeded. as I mentions I tried many was to bypass Xiaomi servers, now I found Miracle Box that promising to do the trick but its for only registered members. also there are some guys that said they can unlock the bootloader for money, but I dont know how trust they are....
I hope some of you guys can lead me to any idea/solution or something....
Thank you all for your time, much appriciated.

So, since 2019 you have used your device without a Xiaomi account, which severely limits Xiaomi services?

never used Xiaomi services...

Try to erase the data with the recovery or safe mode, if the option exists, but anyway if the phone is linked to an account you will be asked for the password.
Accounts are linked with a phone and email number and when you change the number a message is displayed.

Thank you, already tried it...
Is anyone know somthing about this? https://github.com/Canny1913/miunlock
Is the token is the key to success?

To sum up:
You have bricked your phone by locking the bootloader with a Global rom.
The reboot is possible but paying but when the phone reboots Xiaomi will ask you for your account and password.
Never ending Story.

Users who want to flash their phones need to study how to use tools, which ROMs to flash, etc
Eg, when flashing a ROM by Mi Flash, always uncheck relocking of the Bootloader. Then, if anything goes wrong, Bootloader will remain unlocked and one can still flash another ROM to easily unbrick the phone
