Re-lock Mi 8 Bootloader after moving from China Stable to Global Stable

Appreciate if someone can help.
I purchased a Mi 8 Chinese version with China Stable ROM, unlocked Bootloader after waiting 372 long hours and yesterday installed recently released Global Stable ROM. Everything went well and phone worked perfectly. However, when I tried to re-lock the Bootloader, (using both XiaoMiTool and Fastboot methods) the Bootloader gets locked but the phone goes into Recovery bootloop every time with a message at the bottom that "this Miui version cannot be installed on this device....." When I unlock the bootloader again (by booting into fastboot and using Xiaomi Unlock tool) the phone boots normally.
So can I conclude that the bootloader cannot be locked unless I move back to China Stable ROM which originally came with the phone? I read somewhere that Xiaomi has disable the re-locking of bootloader just to curb selling of Chinese versions as Global, as some sellers were selling Chinese versions of Xiaomi phones as Global after installing Global ROMs.

I'm having the same issue as you just did. Not sure why the bootloader can't be relocked. I thought the model # between HK and China versions were supposed to be the same..

Recently xiaomi makes some ugly rules about local and global variant device to prevent Chinese device selling globally and global device selling into china. For that user can flash global rom to china variant device and global variant device to china rom, but we have to unlocked bootloader. Device will perform normally just find device will not worked. Also antirollback terrible disgusting too. I have some xiaomi mobile device and selling them one by one. Only keeping Mi8. If I need more secure device, I can buy iphone. I no need then xiaomi device.
People loving Xiaomi because of its hardware and software with up-gradation facilities. But their operating system optimization is really bad. Every update makes device performance different.

XiaoMiTool is crap...
Use official MiFlashTool => http://download.appmifile.com/images/2018/06/13/f267b936-45cd-4b3d-b15a-947fb4b674b1.zip

Use the option "Clean all and lock" when installing via fastboot

Actually I was reading some things on the MIUI official forum and * apparently* if you have a chinese MI 8 and want to switch to Global rom, your bootloader must remain unlobcked.... I'm not seeing much confirmation on that, but I would be catious...

Yeah, switching to a global rom on a Chinese variant and then locking the bootloader will result in a brick. But I don't understand why anyone would relock the bootloader since most repair shops find out if you unlocked it in the past.

Relock not for warranty reasons, but to get android pay / NFC payment or other banking apps working. Many of them won't work with BL unlocked.

i read that we need an authorized edl account to relock the bootloader, but now it is impossible to get this account..
so this time i'm very dissappointed with xiaomi.

Netflix app and Google Pay needs locked bootloader.

The Mi Mix 2S has the same problem, it seems this person solved it by using recovery version of global ROM with Mi PC Suite: http://en.miui.com/forum.php?mod=viewthread&tid=2943351&page=2#pid27478883
I don't have the device to test it yet, but you should at least be able to keep an unlocked bootloader and use apps that require it to be locked by using Magisk and enabling Magisk Hide on those apps.

I do not know if I can post the link here, but there is a topic in the MIUI forum that gives EDL authorization for just an unbrick. And you must wait for your position in the list.

Magisk...
I think you can use Netflix and/or banks' apps through Magisk hide functions and so be it

:good::good:congratulations my friend. I was already sad that I did not understand.
Its solution is simple but of enormous importance for mi8users.
I also did everything ok, but at mi8 it was different. I also received "this Miui version can not be installed on this device ....."
I downloaded miflash unlock .... romGlobal was already installed on mi8 but with blockloaded bootloader it did not work ok.
Now I'm happy and with GlobalRom stable very fast.:good:

Hi,
I try to relock the bootloader with Global ROM install but the phone haven't sign-in with Xiaomi account and it get the same message as your guy "this miui version cannot..." . Now I can't unlock my bootloader to revert it and my phone stay at recovery or fastboot, can anyone know how to flash it back?

Mi8 CN unlocked bootloader questions.

Because of many threads for bricked devices, I`m opening this thread with all questions about risk and solutions (if there is any).
Q1: Is CN version with unlocked bootloader and Global Rom installed will recieve OTA update without problems like re-locking bootloader?
Q2: If everything from Q1 works, what problems we should expect because of unlocked bootloader?
Q3: Is it possible to disconnect device from seller account, flash CN ROM, re-lock bootloader and bound your Xiaomi account in device to be able to unlock it again?
Q4: Can we expect in future solution for re-lock CN version with official global rom or it is impossible at all?
This is what I`m concerned mostly. For sure there is other questions I missed, but this is basically

Q1: Yes (well I read it in the Mi 8 forums)
Q1: Google pay, netflix...don't work, no ubication in the Mi account....
Q3: Yes I did it. First you need the sellers account their password and their help!!!!, then you flash CHINA DEV ROM (not the stable rom) (same version if you are in android 8.1 take care about the version you flash because now china dev is in androd 9) and lock bootloader. When you start the phone it ask for the password of the seller account you have to put it on the phone and have to tell him to erase the device in their account. 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!!!
You can read this: h***s://w**.igeekphone.com/xiaomi-mi-8-what-to-do-if-you-receive-it-with-unlocked-bootloader-and-global-miui/ (Maybe he was lucky and his cell phone was not linked to the seller's account???)
I talk with my seller and now I have the china dev installed with my Mi account and waiting 720h to unlock the bootloader to install the global rom.
Q4: I hope so

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.

Yeah i guess ill have to endure being tracked 24/7 for a week ... thanks for all your responses. I am happy to know i can just go back to custom rom after the bootloader is unlocked.
I just hope i don't **** it up like last time.

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 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
