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.

Xiaomi has arrived to Europe, but Chinese version still continue to be less expensive (and interesting), but unfortunately not excluded from this type of inconveniences.

Mi8 Change ROMS

Hello
I bought the Mi8 from China this summer and I decided to unlock it so I can try a few roms ( Xiaomi eu , Pixel 2 Port , Lineage etc. ).
The phone came with Global ROM and unlocked via the unofficial method . My friends advised me to install China Developer MIUI 10 8.8.31 then lock the bootloader and unlock it via the official method and I am waiting 720 hours . In about 10 days the unlock procedure will be finished .
So can you explain which roms can I install ? I will install for now the Global Stable 10.0.2 but I am not the biggest fan of MIUI so I will want to install the Pixel ROM for example in the near future but it's on Android 9.0 . Will I be able to return to MIUI 10 Global Stable with Android 8.1 from any Android Pie ROM or Xiaomi eu ROM ?
Thanks a lot !

Hi, what procedure did you follow to relock the bootloader?

I downloaded China Developer 8.8.31 Fastboot ROM and I flashed it via MiFlash and chose "Clean all and lock" .

If you have unlocked Mi8 it means the seller unlock it unofficial by using EDL method . So that means you can brick your device very easily . If you bought it from China you need to install China Stable/Developer and lock it . Then unlock officially with your account then the phone will be less likely to brick if you know what you are doing .

I was on MIUI Global 10.0.2.0. I rebooted into fastboot and flashed 8.8.31 fastboot china developer rom with MiFlash and "clean all and lock". The phone booted into chinese Mi Recovery without MiFlash finishing procedure. I couldn't use MiFlash again because the bootloader was locked. I tried Mi PC Suite in chinese and tried to recover my phone but it didn't work. I think maybe ARB bricked my phone. I don't know for sure. I had checked arb before with getvar and the result was "FAILED" so I was confident ARB was not present on my phone. When the phone booted in Mi Recovery in chinese... there was no text saying "This MIUI version can not be installed on this device". So I had not installed a global rom by mistake on my Mi8 china device. I don't know for sure what went wrong. Anyway, I unbricked my phone with an edl authorised account I bought at S-unlock and now I'm on china stable rom 10.0.5.0 and I am waiting 15 days to unlock my bootloader. If anybody might have an idea what might have gone wrong please share your opinion. Could it be the USB drivers on Windows 10??? I don't know.

damn, i really have no idea what went wrong. you pretty much did everything by the book and this shouldnt happen. do you remember if you ran getvar anti before or after flashing global?
im asking because as far as i know, official xiomi software should return anti 1 from day to present day. variable unknown suggest reseller tempered with bootloader (to unlock?). but when you fastboot flashed official global it should rewrite everything including bootloader so after it should return 1. i could be wrong on this because im still looking for any real info on this topic. but if you open any fastboot rom tgz and look into flash_all.bat, there is a line thar sets anti to 1. so it should be there from day 1. thanks again for you feedback, lots of people are flashing back to china and locking because other people say it is a good thing to do. your case proves it might not be such a good idea.

I ran getvar when I was on the global rom 10.0.2.0. I never got the chance to install TWRP or any rom on my Mi8 because I wanted to link my account to the bootloader first. When I opened the phone from the box It was on MIUI 9.6 and I updated to MIUI 10.0.2.0 via OTA and while I was using this version I ran getvar and then continued the flashing

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:

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.

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?

I just had a similar situation. Only fix is to open up phone and use EDL test points, then find a service offering Xiaomi authorized account to login and flash correct region ROM. You can then bind account and unlock after 7 days.

What you mean with Xiaomi authorized account service?

Normal users can't use EDL flash on this phone, there is an additional authorization process that cannot by bypassed (phone sends a token and expects a signed response from Xiaomi servers). So you have to login to a Xiaomi account which is authorized to use EDL flash. These are generally service center accounts, but you can find some shady looking services online that will log in with their authorized Xiaomi account for a fee.

please, is there any other way to just boot up my k20 pro? it still has fastboot and redmi recovery. please somebody help me !

Never lock the bootloader when flashing a non original ROM. You may now need to find someone who can perform an edl level flash. Just look at other posts, they do mention who to contact but it will cost a few dollars.

Your case is more easy than was mine. Just reflash the original ROM, unlock, and flash the global.

Cant flash original ? how did you flash it ?
I just found a guy fixed it in EDL mode remotely (Paid service )

I wont send this post if i have unlocked one

EDL flash then I'm afraid

Same problem here.
Anyone have a contact who can help me, $$.
Thank you

Edl flashing is easy (if we are talking about the same thing), you just need an original rom and the software. But yeah, not sure if that exists for the Ultra out there..
Software is MiFlash or something like that IIRC.
