Global to Chinese ROM to lock Bootloader

Hello XDA users!
I've bough this wonderful MI8 from AliExpress.
It's a Chinese Market device, It arrived with global ROM and unlocked bootloader.
Since i want to use Google pay and other prohibited apps with the bootloader unlocked i am trying to clearly understand if flashing the Chinese official ROM and locking the bootloader again is a feasible thing or there are some risks? Will the phone be bricked? Will it not? Wich one is the best tool to do it? Where can i find the official Chinese rom?
Thank you!

you need to think twice. if you succeeded locking bootloader. xiaomi maybe not allowing you to unlock it again and ask for binded account
can't you try a safer way by xposed or magisk to hide root, unlocking and trick your apps?
I don't own this device so I can't help you alot

I'm now waiting to my Mi 8 arrives from China and I have the same question. Looking for the answer I found this:
h***s://w**igeekphone.com/xiaomi-mi-8-what-to-do-if-you-receive-it-with-unlocked-bootloader-and-global-miui/
If someone try, please say if works, thanks in advance

if you read the link: h***s://w**igeekphone.com/xiaomi-mi-8-what-to-do-if-you-receive-it-with-unlocked-bootloader-and-global-miui/
say: "ATTENSION !!! You must NOT lock your bootloader with stable version or it will brick your mobile! ONLY Chinese Developers Fastboot ROM."
and the seller tell me this:
"If you lock the bootloader, then must lock it with china rom.
If you lock it when there is global rom , it will brick .
If you need android pay , then better install rom from xiaomi.eu"
maybe with china dev fastboot rom don't brick the phone???

I install the china dev rom (IMPORTANT NOT the china stable rom) and lock the bootloader. The seller give me the password of the account vinculated to the phone and put it when I start the phone then I desvinculated the phone from the seller's account and put my account. Now I'm waiting 720h to unlock and install the last global rom (only "clean" not "clean and lock".
IT'S AT YOUR OWN RISK I AM NOT RESPONSIBLE FOR WHAT HAPPENS BECAUSE YOU CAN BRICK YOUR PHONE!!!! IF YOU DON'T KNOW WHAT YOU'RE DOING DON'T DO IT!!!

Hey Alematbrun.
Did you manage to flash back to Chinese rom and relock the bootloader then unlock again with your account.

Hi. I have a Mi 9 Se from China with global rom and unlocked bootloader. I’m pretending to flash Oeiginal Chinese Rom and lock bootloader. My phone came wit no mi account bind on it. Do I still need seller’s login and password? Or I can flash chines Rom with no worries?

chinese rom with locked bootloader to global rom possible?

Hello all,
Yesterday I received a k20 pro from china with an unlocked bootloader.
I wanted to get rid of the spy/bloatware so i went and tried to install twrp to install another ROM, but for some reason TWRP flipped when i installed it (i think i forgot to turn off encryption) and just decided to stop working altogether. Recovery did not work anymore and so i was stuck in fastboot (bootlooping). After some stressfull googling i found out, the only way to get the phone working again is by flashing the (only) fastboot ROM, which was the chinese variant.
I was so stressed out, i forgot to change the flash option in xiaomi flash tool to "clean all" instead of "clean all and lock"(which is the default, fu Xiaomi).
So now my phone has a chinese ROM and the bootloader is locked.
So my question is:
Once i get the bootloader unlocked again (which will take 1 week hopefully), will i be able to install the global ROM (once it is released) or a better, a non-spying ROM?
Also, i tried debloating the chinese rom, but everytime i apparently debloat too much and the phone just stops working and i need to do a reset.
Does anyone have a proper list of xiaomi applications that are safe to remove (trough adb)? the ones i found remove too much.
Thanks in advance.

Yes, once you unlock your bootloader again, you can flash indian global firmware, which has less bloats, google apps and services included, and poco launcher.
For debloating cn rom, there is a tool here, I'll find and link.

May use this for debloating- https://github.com/Saki-EU/XiaomiADBFastbootTools

Hi, this is the program that i've been using for removing the xiaomi apps, however when some of the listed apps are removed the phone won't be able to restart anymore and i have to do a reset.
For now, i manually removed all the removable spyware by hand and installed blokkada to deny communication to xiaomi servers. I don't dare to remove a lot of system apps trough adb anymore since i had to reset my phone 5 times already... i just want to use it now...

Just endure the pain until bootloader is unlocked again then move over to the Indian rom, its much more tolerable.

This is the safest option. Whilst waiting for bootloader unlocking I just uninstalled anything that could be and disabled anything else that could be disabled. There were still many things I wanted to remove that could not be uninstalled or disabled, but decided I could live with them for a week.
After your week is up, you've got many options. If you like MIUI but not the bloat and spyware, then there are MIUI custom ROMs that remove the junk, xiaomi.eu ROMs being one of the biggest. Otherwise there are AOSP based custom ROMs that are stable enough to use.

Hello, I have a cruel doubt. I was really wondering if after I unlock the bootloader (I have a Chinese rom) doing Global installation I can lock the bootloader? Because you have this possibility and I believe we received normally correct updates, can anyone help me?

NO.
If you try and lock the bootloader with anything that is not the original region you will hard brick the phone.
If you have a Chinese phone, then you can only lock the bootloader when installing an official Chinese ROM.

I think only the account used to unlock the blootloader can relock and re-reunlock it.
If you lock the phone, you won't be able to unlock it again with another account.
It is just a safety mechanism from xiaomi.

You don't need an account to lock the bootloader.
Provided that there is not a Mi account linked to a phone, then anyone who has the phone in their possession can unlock it.
When people have bought a phone already unlock, then accidentally locked it, they have been able to unlock it themselves if the seller has already unlinked the phone from the sellers Mi account

So basically it is possible, if one gets a k20 pro flashed with global rom, that if the seller forgets to remove his account from the phone, you're stuck using ONLY other roms? In other words, in order to relock the bootloader and install official chinese rom, you need to contact the seller and ask him to go on his mi account to remove your phone?

Yes there has been a few cases on these forums where this had happened.
However, you can still use official MIUI ROMs, you can still flash the Chinese ROM and lock the bootloader. The problem then is that you cannot unlock the bootloader again if the phone it's still linked to another account.
If you buy a Chinese phone with a global ROM, why would you then want to flash a Chinese ROM and lock the bootloader? You would be better off just buying the phone still with the Chinese ROM and locked, if that's what you wanted.
People have had problems because they've been flashing an official ROM with the Mi Flash Tool and accidentally left the flash option to flash and lock. When flashing with the Mi Flash Tool you just need to remember to change the default flash option every time you use it.
If you never relock the bootloader, then you will never have this problem and can still use official MIUI.

I actually have another one. Can I install bootloader-unlocked update pscotes in the global rom on k20 pro without losing files, or everytime I have to install full rom?

I'm not sure what you're asking. I'm guessing pscotes is a typing error.

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.

Question How to prepare to sell a CN version Mi 11 Ultra

I unlocked the bootloader and currently have the EU firmware on my phone. How do I ensure my Mi account is not associated with the phone anymore or the unlocked bootloader? Is it best to reinstall the CN version and lock the bootloader again before I sell it? TIA!

Going to settings/MiAccount and signing out. After this, perform factory reset. That should suffice.

Thanks. Wasn't sure if somehow it would remain attached to the account used to unlock it.

Might be tricky if the next guy wants to unlock it with a new mi account but I wouldn't worry about it, just put it on eBay or something!

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.

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
