Is it possible to flash Global rom on locked bootloader?

Hi,
Today I recieved my Mi 8, but it has the china ROM on it.
So my question is:
Is it possible to flash the Global ROM without unlocking bootloader?
Because unlocking of the bootloader will delete the userdata.

Bricked Mi8

Hello,
I have a mi8 bought at GeekBuying. It had a open bootloader and a "Global Rom". I tried to update to the eu Rom. Now I have a bootloader locked and the phone only goes into safe mode and fastboot mode. I tried to go back to the official Chinese firmware which did not work as the phone is bootlocked. Also can not do the unlock process using the Xiaomi homepage as I can not access the dev settings...
Any suggestions? Send back to China?

How is it possible to lock the bootloader? Did u use fastboot lock bootloader? Or using Mi flash?
Normal u can flash Xiaomi.eu rom without a problem with a unlocked bootloader it isn't possible to lock a bootloader by flash the eu rom in Twrp.
By the way, I never and I mean never seen so much ppl with bricked phones.

I used fastboot flash. With the official unzipped Rom from the official site. There was also no option to lock or unlock. Old rom had unlocked written on the bootscreen, now shows nothing about it anymore?
Maybe has to to do with a modified firmware by the shop I bought? I myself did not unlock the phone... Came like this.

I bought it also from Geekbuying. I told them that I want to sent it back, cause the box was not a new one, the box was not sealed and the boot loader was unlocked. I have also a bricked phone and I can't use Mi unlock since my account is not bound to this phone.

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 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?

Fake global

Hi.
Unfortunately, I bought a k20 pro in the global version (aliexpress).
What do I have to do to not have brick? log in to mi account on the phone and Install the original china rom in mi flash and tick Clean all "option (not lock). Then wait again for the unlock bootloader?
having a global rom from aliexpress I can flash twrp right away and change rom ? Non Brick?

Basically the trick is to make sure you never accidentally relock the bootloader.
This normally happens if you've stuffed something up and need to flash a fastboot ROM. When this happens ALWAYS remember to change to 'clean All' when flashing with the Mi Flash Tool.
I assume the bootloader is already unlocked. If so, then you're 7 days ahead of the game and can go ahead and install TWRP and any other ROM of your choice. As long as you do everything correctly then you should have no problems.

I have a fake global and unlocked bootloader. So I can easily install twrp and change rom?
The only one I have to remember is that if I wanted to block bootloader again, I have to do it on china rom?

Yes you can install TWRP and change the ROM.
The normal reason to flash a Chinese fastboot ROM is when you have done something wrong and soft bricked the phone. But yes you would also do this if you wanted to lock the bootloader again.

Okay thanks, I wanted to make sure. Nobody would want to Brick a new phone

I was in the same boat. Just flashed the official China ROM via mi flash including bootloader relock. After I applied for an unlock the official way, waited a week to unlock the phone again and finally flashed twrp, magisk and mi-globe Rom.

I think I will also choose this way and block bootloader again. It will be safer

Wait, so you had the 'Global rom' model? Did they leave the phone associated with the Mi account originally? And where did you buy from?
Just curious because my 'Global rom' model K20 Pro arrives tomorrow. Unfortunately ordered the day before all this stuff came out :/

Sorry if this is a bit newby, but I ordered the same (K20 pro) from ali express, there is no way the global rom is official?
If it's not and the bootloader is unlocked, why is this a problem? Because the find my device won't be working? or is the security compromised if it is?
Is the global rom worse than the Chinese? And if the phone isn't disconnected form the Mi account they used to unlock the bootloader with, arn't I screwed?
Sorry for the salvo of questions..

At the moment there is no global version of the phone. So there is no official global ROM. The global ROM versions currently for sale are using a hacked/modified versions of MIUI. These versions are made by people unknown and could possibly contain malware, etc. which could compromise your security. Probably, the ROM will be OK, but you just never know.
Having the bootloader active unlocked isn't a problem normally and gives you the benefit of not having to wait 7 days. You can flash TWRP and install other ROMs with no problem.
But there are a couple of cases on these forums where people have had things go wrong whilst flashing a fastboot ROM using the Mi Flash Tool. They have ended up accidentally relocking the bootloader whilst also corrupting the system partition. Because they haven't unlocked the bootloader themselves originally, they are unable to unlock the phone again and can't install TWRP to install another ROM.
Some people are now choosing to flash an official ROM and relock the bootloader, to allow them to unlock the phone themselves with their own Mi account. So if they end up in the same position as above, they should be able to unlock the bootloader and easily restore the phone.
However some people, when restoring the phone to stock after messing up, have accidentally relocked the phone. When they've tried to go through the unlock process they have found that the phone is still linked to the sellers Mi account and they are unable to link it to their own account and so are unable to unlock it again.
If you never relock the bootloader, either accidentally or deliberately, then you will not have any problems. But if you end up needing to flash a fastboot ROM, then the Mi Flash Tool default option is to flash and relock, so it only takes a brief lapse in concentration to find that you've got a locked bootloader again. If this happens, I would guess that it's far more likely that you won't have any problems and you are able to unlock it again.

Just be aware that this option also comes with risks. Occasionally some people have found that the phone is still linked to the sellers Mi account, they are then unable to ink it to their own account and so cannot unlock the bootloader again.

[Question] re-lock boot loader

Mi 9t Pro global Rom Miui 10, android 9.
will flash K20 Pro india ROM miui 11, Android 10 fastboot.
why all recommend keeping bootloader unlocked?
i don't want the hassle of banking apps and use Magisk. so what's the problem here of re-lock bootloader after flashing the new ROM?
technical details are most welcome.

Locking bootloader with a different ROM region installed will brick your device. Unbricking will require further wait for bootloader unlock time or you'll need EDL method which I'm not very aware of how it's done.

why locking bootloader with another region rom installed will brick my phone?
and what you mean by brick that it'll never boot?
i got below reply from reddit, what do you think about it??
You are flashing a different version of MIUI. It's not what a lot of people call a ROM (although you are technically correct) . It's not like if you flashed a third party ROM like Lineage or xiaomi.eu... You can relock the bootloader if you have an original xiaomi system and recovery and did not modify your bootloader through a rooting tool (such as having Magisk installed as they get installed and run through a procedure called k-exec that patches the bootloader instead of the system so the hack is unknown to the OS).
Bootloaders are locked to prevent tampering with such exploits. Magisk is not malware but malware and spying tools can be implemented in the same way.
When the bootloader is locked only a ROM and a recovery made by the company that makes the phone can run.

I am not sure about that now. But it bricks because that's how Xiaomi have put. I may be wrong but if many people are saying the same then there should be a reason.

With official ROM either Global MI, Global EEA or China, with Xiaomi MI Flahs tool you can block the bootloader without any problem.
If you do not usually change the rom, or to custom rom or recoverys custom, it is advisable to block it since you cannot download netflix from the play store and some bank applications mark errors. Otherwise you can unlock the bootloader.
The most important thing about keeping it unlocked is that you lose the equipment warranty.
And the benefit of having it unlocked is that you can change from rom or custom rom, and you don't have to wait for xiaomi time to unlock it again; but lose the warranty.
But you open custom possibilities.

thank you guys, but i really need to know what is exactly meant by hard brick?
is it not to boot again or what??

Hy!Are you sure that if I own an Chinese variant of k20 pro and if I relockmy bl I won´t brick my device by relocking it?I just unlocked it today and I plan to instal the EU rom and relock my bl.

Just to make it clear...
Chinese K20 Pro needs to have Stock Chinese rom if you want to relock the phone! Without Mods or anything. Just clean Chinese firmware!
The same for indian variant. Only indian firmware without mods.
Also for Mi 9T Pro! Stock rom without mods!
Even TWRP isn't allowed If you wanna relock the bootloader!
If you cross flash roms and relock the bootloader you will brick your device! Your phone won't boot! You will need to open the backcover and boot it into EDL mode and blablabla. There is a thread about that.
Can be found HERE!
