Received new MI 9 with unlocked bootloader

Hi all.
Just got the transparent edition and it arrived with unlocked bootloader. Already done a ota from 10.2.15 to 10.2.17.
What concerns do I have with this? Obviously I cant relock bootloader and don't really want it locked anyway. Will it be tied to someone else's account because the bootloader was unlocked? What can I flash what can't I flash? Should I return it?
Just want to make sure before I brick a thousand dollar phone.
Cheers

When unlocked, a phone is usually linked to a Miui account.
- If you're in Europe, we got DRM Widevine L1. Unlocking + Flashing could give you WIdevine L3. Remember : Unless you're in Europe, Widevine IS L3 !!
If you're outside Europe, check the LTE/4G bands. They're usually the same, but like the DRM, you can't really "flash" 4G/LTE from a chinese phone to an african, russian phone for example...
When done, try wiping the phone and getting it locked to your phone number in Miui.

That's what i'm saying. Someone else has unlocked it and I just received it yesterday.. That is one of my concerns if I flash it with mi tool will it need someone else's password or mine even though it was set up with my mi account.
The device is tied to my mi account done that on setup . So that's what I'm asking because i never unlocked the bootloader though and someone else did what will happen if I reflash with mi tool. I think it would want my password but I'm just making sure before I do anything.
Cheers

Said that in my post. About relocking

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.

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.

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.

[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!

Question Change MIUI region version and lock bootloader

Hi,
I have a Chinese Mi 11 Ultra. I have used the Mi flash tool to flash the EU based version of the ROM but I did not lock the bootloader. This has brought in some problems, such as GPay not working, which I dont really mind but the Mcdonalds app with the coupons also wont start up.
I am wondering, if I get the EU miui13 fastboot rom (original from Xiaomi), and use the mi flash tool to flash it, can I also lock the bootloader? Will it be fine or will it brick the device?

I believe this answers your question: https://c.mi.com/thread-2584760-1-1.html
The TLDR is you can only lock bootloader in China devices if you flash the China ROM. Some people claim to have successfully flashed China ROMs on Glogal phones and locked the bootloader without any issues but you'd be taking a risk.
