Xiaomi Mi 9T Pro Bootlooder locked - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

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.

ok this is a start, any advice how to unlock the bootloader?

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.

This model is from 2019, seems strange that Ali sells new ones.
And you still don't understand that there can't be a Global rom on this model with the bootloader locked.

The bootloader was not locked when I purchsed the device...

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

Re-lock Mi 8 Bootloader after moving from China Stable to Global Stable

Appreciate if someone can help.
I purchased a Mi 8 Chinese version with China Stable ROM, unlocked Bootloader after waiting 372 long hours and yesterday installed recently released Global Stable ROM. Everything went well and phone worked perfectly. However, when I tried to re-lock the Bootloader, (using both XiaoMiTool and Fastboot methods) the Bootloader gets locked but the phone goes into Recovery bootloop every time with a message at the bottom that "this Miui version cannot be installed on this device....." When I unlock the bootloader again (by booting into fastboot and using Xiaomi Unlock tool) the phone boots normally.
So can I conclude that the bootloader cannot be locked unless I move back to China Stable ROM which originally came with the phone? I read somewhere that Xiaomi has disable the re-locking of bootloader just to curb selling of Chinese versions as Global, as some sellers were selling Chinese versions of Xiaomi phones as Global after installing Global ROMs.
I'm having the same issue as you just did. Not sure why the bootloader can't be relocked. I thought the model # between HK and China versions were supposed to be the same..
Recently xiaomi makes some ugly rules about local and global variant device to prevent Chinese device selling globally and global device selling into china. For that user can flash global rom to china variant device and global variant device to china rom, but we have to unlocked bootloader. Device will perform normally just find device will not worked. Also antirollback terrible disgusting too. I have some xiaomi mobile device and selling them one by one. Only keeping Mi8. If I need more secure device, I can buy iphone. I no need then xiaomi device.
People loving Xiaomi because of its hardware and software with up-gradation facilities. But their operating system optimization is really bad. Every update makes device performance different.

Actually I was reading some things on the MIUI official forum and * apparently* if you have a chinese MI 8 and want to switch to Global rom, your bootloader must remain unlobcked.... I'm not seeing much confirmation on that, but I would be catious...

Yeah, switching to a global rom on a Chinese variant and then locking the bootloader will result in a brick. But I don't understand why anyone would relock the bootloader since most repair shops find out if you unlocked it in the past.
Relock not for warranty reasons, but to get android pay / NFC payment or other banking apps working. Many of them won't work with BL unlocked.
i read that we need an authorized edl account to relock the bootloader, but now it is impossible to get this account..
so this time i'm very dissappointed with xiaomi.

Netflix app and Google Pay needs locked bootloader.
The Mi Mix 2S has the same problem, it seems this person solved it by using recovery version of global ROM with Mi PC Suite: http://en.miui.com/forum.php?mod=viewthread&tid=2943351&page=2#pid27478883
I don't have the device to test it yet, but you should at least be able to keep an unlocked bootloader and use apps that require it to be locked by using Magisk and enabling Magisk Hide on those apps.

I do not know if I can post the link here, but there is a topic in the MIUI forum that gives EDL authorization for just an unbrick. And you must wait for your position in the list.
Magisk...
I think you can use Netflix and/or banks' apps through Magisk hide functions and so be it

:good::good:congratulations my friend. I was already sad that I did not understand.
Its solution is simple but of enormous importance for mi8users.
I also did everything ok, but at mi8 it was different. I also received "this Miui version can not be installed on this device ....."
I downloaded miflash unlock .... romGlobal was already installed on mi8 but with blockloaded bootloader it did not work ok.
Now I'm happy and with GlobalRom stable very fast.:good:
Hi,
I try to relock the bootloader with Global ROM install but the phone haven't sign-in with Xiaomi account and it get the same message as your guy "this miui version cannot..." . Now I can't unlock my bootloader to revert it and my phone stay at recovery or fastboot, can anyone know how to flash it back?

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.

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.

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.

Thank you very much for help. I have read both but unfortunately i can not UNLOCK my bootloader… when i was trying to unlock the bootloader through MI UNLOCK, it says "Current account is not bound to this device". Otherwise if this was succesful and i could unlock it, then it would be easy i believe.

Since you locked the boot loader, you'd have to flash (with fastboot) using the same flavor of miui which was installed. (example: chinese or eu variation), otherwise you won't be able to boot.

Yes, that i understood… There was EU variation with unlocked bootloader, which i do not know why, but okay…

First of all you need chinese mi assistant
Second you need try three versions of roms(eeu , china , global) but im pretty sure that your phone is chinese version that bought from gray market and they unlock bootloader to install global rom
After you download these tell me, i guide you
Be sure download recovery rom (not fastboot)
It has .zip extension not tgz

If you know how to sideload the rom then everything is become okay dont worry
After successful debrick you must bound you mi account to your phone and wait for bl unlock then reflash with mi flash tool and global rom
AND DONT LOCK YOUR BOOTLOADER AGAIN
Yes, unfortunately i do not know how to sidload the rom... But when i have Chinese rom downloaded then what do i do with that? I connect the phone through mi assistant and there it can be flashed?
I had the same thing happen. You need to force a firmware flash ?
I had someone on xda recommend an excellent recovery tool.
It's called 'miflashpro'. It can be hard to find the English version. I did eventually but actually unbricked my Mi9 with the Italian version.
99% chance your cell can be fixed this way
bricked too
I'm having the same problem here, after wipe in twrp mode my phone restart and i'm blocked on bootloader screen.

I did the same thing with a Mi CC9 relocked the bootloader by mistake thinking it was like any other android phone. Did you have a Xiaomi account associated with the phone and signed into after enabling oem unlock in developer options.
If tha'ts the case you can use https://en.miui.com/unlock/ tool from where but it checks your phone number to see whether its associated with mi unlock.
Otherwise you will have to use EDL method which involves disassembling back of phone and shorting out two pins to initialize EDL data transfer but you need a EDL associated account this (belief xiaomi has revoked everyone access to these)
Hello all members.I had same problem and I open this phone with suport from youtube .I try clean some connector and worming cpu and motherboard. After change the battery with new. When close the phone they suprised me and working good.After 10 hours again close and bricked. I try sake and again open .So....the real problem its not CPU and motherboard but some connector dont touch good. Sory for my English. I hope some other find which connector have problem in this phone and pm me. Now my MI 9 working good but I keep bickerful ...

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?

Bought it from Amazon. It was global. I had to wait for about 7 days to unlock the bootloader

Unlocked bootloader from China, unsupported apps

Hello,
I've been sold the Mi 9 t Pro 256 GB (or k20 pro) by what I thought was a trustworthy store, Phone House.
It turns out the device was sent from China and comes with the bootloader unlocked and Global Rom:
MiUi Global 11.0.5
Stable
11.0.5.0 QFKEUXM
I've realised some apps don't work from Google Play Store (Netflix, Disney Plus and probably more) and apparently it's because the bootloader is unlocked.
What I want is an official ROM with locked bootloader, so I don't have to download official apps from third party websites which I don't necesarily trust.
However I've been told I will brick the phone, because I don't have access to the account they used to unlock the bootloader and install the Global ROM; at least if they forgot to unlink the phone from that account, which I'm told is really common. I just want to own the phone I paid for, which seems quite reasonable to me.
Is there any way I can check if my phone is still linked to the chinese account they used to unlock the bootloader? Has anybody gotten out of this situation and if they did, can they tell me what steps should i take?
Regards.

Can you link your phone with your Xiaomi account and number?
Most of us here wish unlocked bootloader , install twrp and magisk and most of your app problems go away.

If your phone is originally a Chinese K20 Pro then you can only lock the bootloader with the Chinese ROM. If you try and lock the bootloader with any other ROM you will brick the phone
It doesn't matter who unlocked the bootloader. You will be able to flash the Chinese fastboot ROM and lock the bootloader, without any problems. After which you can use the phone completely as normal.
If you decide you want to unlock the bootloader again, you will have issues if the phone is still linked to another Mi account. Some sellers have been good at removing phones from their Mi account, some have not.
If you flash a different region ROM and lock the bootloader and you haven't properly linked the phone to your Mi account before (which is done during the bootloader unlock process), then your bricked phone will be hard bricked and can only be recovered by flashing with an authorised Mi service account.
First job is to determine exactly which region model you have. This can be done with an online IMEI checker. Then download the correct fastboot ROM for the phone and flash it with the Mi Flash Tool, using the flash and lock option.
