Change ROM Xiaomi Mi 9 without unlocking bootloader - Xiaomi Mi 9 Questions & Answers

Good afternoon everyone, I recently acquired this terminal through a telephone company (Vodafone) and I came with a rom that they put something coated. My question is: if I want to install the stable global rom, do I need to unlock bootloader or can I do it through fastboot?

Unlock bootloader, or try to use MiFlash Pro Tool

What to do first when I receive the phone?

Hey everyone,
I was just wondering what I need to do when i receive the device. I am in Australia and the phone might be the Chinese model.
So is there anything I have to do with the phone to make it usable as I've heard you need to flash on the global ROM.
How do I properly set up my device for use?
Thanks

Not easy.To flash the global version miui,you need to unblock your boolloader, then download the global package,and flash it with the miflash.But to unlock the bootloader,you need a mi account and make a Application.

If you bought from a chinese-based online store, most likely your device has a fake ROM. To get rid of that ROM, you need to unlock bootloader. No matter if you want to flash an official ROM or unofficial xiaomi.eu. You can try to change ROM with MIUI Updater app, but most probably it will not work from a fake ROM.
To unlock bootloader you need at least a couple of things: a xiaomi account you can create here Mi Account -> account.xiaomi.com
After you create your MI account you need to request unlock here MI Unlock en.miui.com/unlock and wait several days to be approved for unlocking. In my case it took 4 or 5 days before I received an SMS of approval.
Then download MI Unlock app (Windows) and search a manual for unlocking device (you need to activate developer options).
In order to unlock bootloader you need a Chinese ROM (stable or dev) but If I'm not wrong all 'fake' devices come with a chinese-based ROM, otherwise wouldn't be a fake ROM?
After you achieve unlocking you can flash any ROM, Global or China, unofficial like xiaomi.eu, etc..
Flash global rom without unlocking bootloader
There is a way to flash global rom without unlocking bootloader using special USB cable that you can make yourself if you still want to do so i'll gladly show you how I did with my phone.
If you are tired and irked by MIUI, I would strongly recommend you to quickly apply for Bootloader unlocking permission on the official Miui site. Afterwards, unlock your bootloader and install official TWRP recovery and a ROM of your choice such as CM14.1. That way, you will be able to experience the true "openess" and magic of Android!
You can install CyanogenMod ROM, but unfortunately you will get no updates, since project has been discontinued on Dec 31 . Their successor is http://lineageos.org/ but there's nothing on their web yet.
Do create a MiAccount.. and do remember your security pattern... what ever you intend to do next do those two things
no need to unlock bootloader.
Xiaomi flash ROM came with 2 method.
you can flash not only from fastboot mode ( bootloader mode ) but also from edl mode ( QDloader 9008 mode ).
- fastboot method need to unlock bootloader.
- EDL method not need to unlock bootloader .
EDL method even can unlock bootloader with unofficial method

flashing official rom with locked bootloader

hey.
i want to purchase the chinese version of mi 8 and i wanted to know if it is possible by now to flash the global rom (official of couse) without unlocking the bootloader?
Sorry It´s not possible:
With locked bootloader it´s just: chinese phone -> chinese ROM
if you unlock and install global, you must keep it unlocked or it won´t boot (soft brick).

[Q & A] help Xiaomi Mi 8 won't boot

Firstly I want to thank every one here
I want to clarify for the first that the phone was already unlocked when I bought it. All go well until the day of doing this stupidity
I put the version 8.9.20 it got stuck (this miui version can't be installed on this device __1st attachment) but when I wanted to return to 10.0.20 with fastboot it tells me locked phone I managed to update to 8.10.25 with another tool but I was still stuck with this screen (1st attachment)
So I thought I need to unlock it I launch the unlocking tool he announces this message (current account is not bound to this device __2nd attachment)
Conclusion phone that has not done yet a month with totally unusable I was so happy with this phone that I could not return to iPhone.
Please find me a solution dear friends
My mi account id is 144253908
My Device is Xiaomi Mi 8 Global version bought from Gearbest
Do you have an unlocked bootloader? Flashing different rom, like you had installed on your phone (global, xiaomi.eu) need unlocked bootloader and twrp recovery. Or, if you had opened bootloader, and you flashed with Mitool, then you should unmark befor flashing the flash and lock option, cos ist closing your bootloader and bricking your device. Also have the last time xiaomi devices antirollback. For more info have a look in forum!Its already thread about this!
Can i resolve this problem with edl xiaomi cable ?

Global ROM with locked Bootloader on Chinese Varient k20 pro

Hi Android Enthusiastic's
I was totally impressed by Redmi k20 pro specs and price and I had brought it from China next day it was released in Chinese market, I had to deal with slot of Chinese bloatware and I was finally waiting for official global ROM to released and I unlocked bootloader and flashed global ROM and when I try to relock the bootloader it gets stuck in recovery mode
And works fine with unlocked bootloader
And later I came to know that Xiaomi had actually did this on purpose that no should do like this
I ask all you is there any workaround for this that I can have official global rom and locked Bootloader
Because unlocked bootloader can lead to hacking and loss of sensitive information and potential for virus attack
Since you have the chinese variant if the phone locking it's bootloader will limit the phone to ONLY being able to boot the Chinese ROM or one of these fake global ShopROMs which nobody should use (in my opinion).
I don't think it possible to flash the official global ROM and lock the bootloader. Maybe some day the Pro's will be able to convert a Redmi K20pro to a Mi 9T Pro with baseband and bootlock support but at the time of writing this is not possible.
Until then you have to choose between Chinese ROM with locked bootloader or any other ROM with unlocked one. I use Xiaomi.eu ROM with unlocked Bootloader and deem the data encryption safe enough.
A thief could boot TWRP, format data and have my phone but that is a risk I can take. In that case I might even still be able to lock the phone with my mi account if the thief used MIUI
