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.

No don't do it. Check my thread or some others on this forum if you do it'll brick your device.

[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!

replace russian rom official with global rom official

i bought a mi 9 lite and it came with the russian rom.
I wanted to unlock the bootloader and install the official globlal ROM with mi flash. can i lock the bootloader again with me flash when i install an official global rom?
or
is there a guide to install a global rom without unlocking the bootloader? and without using tools?

You need to first unlock your bootloader in order to fastboot flash the global rom (using MiFlash). After that in the MiFlash tool there is an option to "Flash all and lock" which will lock your bootloader again. Unfortunately there is not a way of doing it to my knowledge without unlocking your bootloader.
Here's the official guide here: https://c.mi.com/oc/miuidownload/detail?guide=2

Never, ever re-lock your bootloader as this will result in a hard brick that can only be resolved with EDL/authorized account!

Not to my knowledge. I have done it before with my device. Sure if you want to use custom roms/recoveries you will need to unlock your bootloader again which you can do if you are using an authorised account. However, if you are really worried about this happening, you might as well just keep your bootloader unlocked.

I bought a mi cc9 lite that came with a russian rom.
Before i could unlock my device, i was able to flash a global rom with a non official tool which name i can't remember.
Global rom was the only one i was able to flash. So yes it's possible.

ok

On which ROM and Device you CAN and CAN'T Lock Bootloader!

Question Flashed Indonesian Rom in Sweetin and relocked Bootloader😥😫

My friend flashed Indonesian fastboot Rom in indian RN10 Pro Max and locked the Bootloader, now he is trying to add acount and device to unlock it again but if fails everytime.
An error shows "Couldn't add. Device basic data verification failed"
Please see the attached screenshot.
Do you have any clue how to solve the issue?

you were should use only format data not all & relock.
There is three .bat orders:
one with erasing user data.
one with keep user data.
one with format and relock.
In your case you have to unlock it again.

Can't unlock, can't add account and device. Always shows the error mentioned in the post.

I had to abandon my previous xiaomi phone just for this reason. Accidentally locked the bootloader and couldn't unlock it ever. "The find device storage corrupted, your device is unsafe now".
Couldn't add miui account.

You did the same? I mean flashed another region's rom and locked bootloader?
My friend told me that he did the same in his Redmi Note 8 and then re-unlocked and flashed stock regions's rom, it was fine for redmi 8 so he did this in RN10 Pro too.

I actually did worse. I was on non-miui Rom then flashed the Fastboot without unticking the lock option. Guess what though the sensors of my MI5 is all okay nothing works due to wrong persist file.

Could you please share how to flash? since bootloader is locked cant flash anything.

Maybe you did not get my point, we are stuck in another region's ROM with locked bootloader.

Try find Xiaomi repair support center and tell them to help you flash official Indian ROM for you.
You can boot into the system, and the device said it's locked and secure, so it's not hard brick. Should be fine for them to help out, if the warranty is covered under the policy.
Be prepared for data loss, so you need to backup what you want to keep.
Don't tell them you flash a wrong region ROM. Just say the phone seems a bit strange, so want them to help clean flash and update official latest ROM.

You can try flashing stock with mi flash tool by rebooting to bootloader. Recovery ROM might work even with locked bootloader

Question Lock bootloader after flashing Indonesia ROM?

I am using Redmi 9 Power. Global version.
I was wondering if I unlock it's bootloader, flash Indonesian ROM so I can use Mi Dialer, could I then relock the bootloader so Google Pay and other banking app work?
I understand that you can't relock the bootloader after flashing a custom ROM. So I guess my question is,
If I flash official Indonesian ROM, will it be considered stock ROM or custom? And could I relock the bootloader?
Can I do that using Mi Flash tool?

I don't know if it can be original or custom ROM if you flash it with official Indonesian ROM, but if you flash with Mi Flash, select "flash and lock", the bootloader will be locked

Stock Recovery will never allow custom ROMs to be flashed. Only Stock ROMs can be flashed using Stock Recovery.
