Unlocking then relocking then unlocking again? - Xiaomi Mi Max 2 Questions & Answers

I'm considering buying a Mi Max 2 from china. It is a Chinese version, but with the global ROM preinstalled (the retailer explains that the box will have been opened to allow this). My questions then:
1) Would the retailer have had to unlock the phone via http://en.miui.com/unlock/ etc?
2) If so, I read that "fastboot oem lock" would relock it.
3) Does 3) put it back in the state before step 1) above but with the global rom (ie with find mi working, high security back)?
4) Would I need to go back to http://en.miui.com/unlock/ to unlock it again?
5) If the retailer had already unlocked the phone, does that mean the device is registered to their account? How can I get it associated to mine?
6) What does the "OEM unlocking" switch do in Developer options?

no need to unlock bootloader as long as you stay on official miui stock roms. so u can switch between china stable, china developer, global stable and global developer roms without the need for unlock

That's good to know!
Generally is unlocking irreversible, or does the fastboot command put it back to its initial state?

u can relock the bootloader. however, since u need permission for unlocking the BL, it might be difficult to get repeated unlcoking permission from xiaomi for the same device. so if u decide to unlock it, just leave it so until u sell it...

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

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.

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.

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?

How do I unblock the bootloader on the Xiaomi Mi 8?

I'm thinking about buying a Xiaomi Mi 8 today, but I'm really struggling to find out how to unlock the bootloader so I can flash TWRP etc.
Can somebody point me in the right direction please?
I'm relatively experienced and was running lineageos on my old One Plus One.
Thanks

1. Developer options -> enable oem unlocking and usb debugging -> mi unlock status then tap add account and device(you need mobile data for this)
2. Apply for unlocking here and follow the steps written there. Your mi account when logging in for unlocking should be the same mi account on your mi 8.
Note: when you try to unlock for the first time you will get an error. This is because you need to wait for 7(or is it 15?) days before you can proceed on unlocking your device. So, be sure to apply for unlocking as soon as you get your device.
P.S. welcome to the mi 8 community!

Yes, unfortunately it is 15 days
Make sure to go ahead and complete the steps. Because if you wait a month or 6 months, you still have to wait 15 days before they will allow the unlock. Highly annoying!
Make sure about the version you buy. The are China version and international version. There were sellers selling Chinese version with global ROM installed, this means the bootloader is already unlocked but you could have serious problems if you relocked it. So if you're not Chinese make sure to buy a global version with locked bootloader.

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.

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.

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.

Question Re-lock bootloader

I have a Mi11 with a preliminary Global official ROM but it's rooted and of course bootloader in unlocked: unfortunately Google Pay and some bank apps do not work.
I first removed root, by deleting /system/xbin/su but Google Pay still complains so I think I need to unlock bootloader.
I think I have two options:
- 1 - put phone in fastboot and run "fastboot oem lock" from adb
- 2 - use Mi Flash tool to flash an official ROM and choose "clean all and lock"
What would be the best?
Do I loose data with both or either methods?
I've read that method 2 may put the phone in an unusable state...
Thanks

Where can I get this official global ROM for the Mi 11? Or do you mean xiaomi.eu? What I know is if you flash a different ROM than the original one with the bootloader open and close the bootloader again, you have a brick.

You cannot it's a test device and got it sorted out with Xiaomi engineer: being a test rom, locking bootloader will make phone unusable. Now O have to unlock it and keep it like it is till official build arrives. In the meantime I could try with magisk hide

Is there a official global Rom for MI 11? Shure?
There are 2 ways:
1. Use Magisk and Hide Root and Unlock from apps you need, worked for me at MI 10 Ultra with xiaomi.eu-Rom
2. Relock Bootloader, but keep an eye on the fact, that relock is only possible with original delivered ROM, otherwise your phone will be bricked...
and after relock you will not be able to flash any rom, so, please flash first and do relock after flashing rom
Regards
