Stuck in fastboot, Bootloader is locked! Need help!

I have flashed my device without enabling debug mode. I have used Mi Flash to flash my device. After a reboot, I got stuck on fastboot, but bootloader is locked. Also, I can't enter on twrp...
If I do: fastboot devices, my device is recognized by PC.
If I do: fastboot oem device-info, all information is false except device tempered...On "device unlocked" it shows false too... It means that bootloader is locked.
if I do: adb devices: under List of devices attached, there is no device.
What should I do? Please help me out.

Bro it'd be highly appreciated if you could guide me what that is and what will it do ? i opened the website and it says you must have officially bootloader unlocked.

If your bootloader is locked, you need to unock it first before you can do anything. If you had registered your device with your Mi account, you can still do that following this description:
https://www.stechguide.com/mi-flash-unlock-tool-to-unlock-bootloader-of-xiaomi-devices/
If you did not register your device before, there is no way to get it repaired but by an official verndor or Xiaomi customer support.
Sorry if that is bad news for you.

The issue is, my mobile isnt bound with my MI account. cant unlock. my mi account is unlock supported but my mobile isnt connected to my account. thats fuked up.
I bought the mobile from china, but i'm not in china. i cant claim warranty. i dont know what would be the procedure now.

Yeah, same for me. Also bought mine from a vendor in China.
Good phone, but without support within your country, there is nothing you can do now.
Sorry for the bad news, mate.

The only way its go to EDL mode by forcing its by hacking the hardware to force EDL mode and do test point to reach edl it will detected as qloader9008 hub in the device manger and you can flash rom using this method
Reference
Its in indonesian language but atleast the video explain how to go to EDL mode
Goodluck

Cool thing! Does it also work for hard bricked devices?

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.

: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?

Relock bootloader for account bound

Hi guys. I would like to know a thing:
I have bought a Mi 8 already unlocked from a shop. If I want to relock the bootloader again and bound my account to it, for future unlocks in case of wrong flash with Mi Flash (default flash mode is: "clean all and relock", that I can also omit to see for error), can I flash China without incurring in a brick? Because the phone will be delivered to me with Global Rom (that I know generate a brick with relocked bootloader).
Thanks to who will answer me.

I have the same question... It's possible change the account used for the bootloader unlock?

Without any other method to do this, we can only relock bootloader and follow the common way to unlock it with own account.

I purchased a Xiaomi mi 8 with unlocked bootloader without notice from the reseller. The outcome when I updated with miflash was a bricked phone. When I tried to use miunlock I saw a message that my phone is not bound to this account.

I am using xiaomiadb.exe . You boot in recovery mode and then you drag and drop the rom over xiaomiadb. Pc suit sees the version. I have managed this way to change many roms, but the main problem is the boot loop.

Yes, I have tried everything I could think of. I am afraid that the only solution is to use Mi unlock, but I can't to that because the reseller send me the phone with unlocked bootloader. The program checks at the begging if I have permissions, then checks if the phone is a Mi 8, it passes that test too, but the message I get then is that this phone is not bound to this account.

I have asked Xiaomi Global service about that. They don't offer support. They don't recognize the Chinese e-shops as authorized resellers. And I suppose that a phone can't be bound to two accounts. The only thing I can say for sure is that the global version has a red label on the box and the manual is in English. Watch the video. https://www.youtube.com/watch?v=4Nx-jjTVh_8&t=107s

So it can't be possible to flash anything (also China, that was the born ROM of this phone) with option "Clean all and relock" of Mi Flash, without incurring in a bootloop?

The fact is that you can bound the phone to every account, if you can boot it with locked bootloader.
But if this can't be done, developer options menu will show you that bootloader is already unlocked, without possibility of bound your own account.

Oh wait, you can't use mi flash because your account it's not authorized for EDL.
Now I have understand because you can't relock bootloader. ?

When miunlock starts it checks if I have permission for EDL. It passes the test. But then it says that my phone is not bound to my account. The bootloader was unlocked so I suppose someone has bound my phone with his account.

Ok, so you can't use Mi Flash.
Now it's all clear.

I'm having an idea ... My device is about to arrive. It will be a Chinese variant with bootloader unlocked by the store for installation of a global ROM. So if I flashed a Chinese ROM again, I could re-block the bootloader, correct? So I will boot the phone with the blocked bootloader in the Chinese ROM and I can associate my account and unlock the bootloader again, only this time with my own account. Would it work?
Sorry for my english, I'm using the Google Tradutor.

The problem is that you need to bound your account to your Mi 8, otherwise you can't use Mi Flash to relock your phone.
And you also can't lock it by fastboot, because this operation delete recovery and system partitions, generating a total brick.
Unfortunately my current Mi Max 2 was one of these unlucky phones, and I have learn lesson myself.

The best thing that you can do is:
Use last version of Mi PC Suite 3 to flash global and twrp to flash custom, and if you need to return on global from twrp, just flash original Xiaomi recovery and reuse Mi PC Suite 3.

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.

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.

Never lock the bootloader when flashing a non original ROM. You may now need to find someone who can perform an edl level flash. Just look at other posts, they do mention who to contact but it will cost a few dollars.

Your case is more easy than was mine. Just reflash the original ROM, unlock, and flash the global.

Cant flash original ? how did you flash it ?

You said your phone can't boot, get into fastboot, download the oficial fastbook rom to your smart, and just re-flash using the cable

I wont send this post if i have unlocked one

EDL flash then I'm afraid

Same problem here.
Anyone have a contact who can help me, $$.
Thank you

Edl flashing is easy (if we are talking about the same thing), you just need an original rom and the software. But yeah, not sure if that exists for the Ultra out there..
Software is MiFlash or something like that IIRC.
