Unlocked the bootloader - no waiting time - Xiaomi Mi 8 Questions & Answers

I bought a new Mi 8 / dipper and went to unlock the bootloader. Needed a bit of fiddling, but I managed to do it with some helpful posts here on XDA.
To my surprise, there was no waiting time to unlock it – even though everyone else seemed to have to wait for 160 or 360 hours. Even very recent reddit posts (just 2-7 days old when I tried to unlock my phone) mentioned that they had to wait.
It's my first Xiaomi phone and I created a Mi account with the phone to unlock it.
Does anyone know what could've caused this? I certainly won't complain, just wondering if I possibly have a refurbished phone or something like that.

I too bought a Mi8 and when I unlocked it was expecting a waiting period as I have read but instead it unlocked instantly. What I think is the stores bought a Chinese model cause they're cheaper, unlocked the bootloader, flashed Global ROM, re-locked and sold.

It is not possible to install global ROM on Chinese version and relock bootloader. You will hard brick your phone in that case. The same with Chinese rom on global version. Bootloader must be unlock to do that.

Need help, bought phone, it's on Global ROM but bootloader was relocked

So this is my second Mi Mix. I know my way around it a bit. Anyway I was trying to flash TWRP and it won't work. It appears the bootloader is locked. Apparently the original retailer who sold the phone flashed the global MIUI rom and then relocked the bootloader and reflashed the original recovery.
I have already requested to unlock through Xiaomi but I'm not sure if it will work being on this rom... once I get the text back from them that is.
I'm unable to flash the Chinese stock rom in MiFlash because the bootloader is locked. I've tried just about everything but it appears I'm stuck waiting on Xiaomi to send me the unlock text but my concern is that I won't be able to do it because I'm not on the stock rom.
Any input would be greatly appreciated.

You dont need to request for another unlock code. The unlock code is associated with your Mi Account, meaning you can unlock any Xiaomi device once you sign in with your Mi Account on the device. Once signed in, you just need to use the Unlocking app.
Considering this is your 2nd Mix, I'm assuming you had received an unlock code for the first one. If so, you're good to go. You just need to do as I mentioned above.
If you dont have an unlock code yet, once you've received it, the procedure is fairly simple. Just follow one of the guides here and you'll get to wherever you want,be it Official, EU or a custom ROM.
Hope this helps!
Cheers!
The first one I bought already had the bootloader u locked so I don't have a code. Once I receive a reply from Xiaomi with a code will I be able to unlock even though it's on the global ROM and not stock?

Yes. once you have the code, you can unlock regardless of whatever ROM is installed on the device. FYI, my phone came with a Vendor ROM but locked bootloader just like yours. I don'"t think the Vendor relocked it. I'm assuming that Vendors receive signed Custom ROMs from Xiaomi which is then flashed by Vendors using stock recovery. If they have a signed ROM file, the bootloader doesnt have to be unlocked. It just installs like an update.

Didn't know you had to unlock bootloader for Chinese ROM with miflash, you sure it's not the way you unpacked the file.
Yeah I'm pretty sure it requires bootloader unlock. The first Mix I had was the 128gb version and I sold it last week. Before I sold it the guy wanted me to flash the chinese rom back and I did it using mi flash and it worked just fine. Used the exact same file this time and it won't work, it fails right off the bat. Also in the guide that's posted here for flashing the Chinese rom it says you need the bootloader unlocked.
I guess it's one of those things that people assume the bootloader is already unlocked if you're flashing the Chinese rom since you'd have to have unlocked it already to get off of that rom in the first place.
I'll just sit back and wait for my unlock code I guess. Hopefully they don't take the full 10 days to get back to me.

Vendor ROMS aren't signed or sanctioned by Xiaomi.
Given Xiaomi doesn't even produce a general Global ROM for some models of it's handsets (such as the Mix) because they only sell them in China, it would make little sense for them to then sign Vendor ROMs for such handsets given they're all but exclusively used by international sellers.

China box china rom

Hello guys im really interested with this phone. Bang for the buck. But many people are making a fuzz about global roms and china boxes.
Will it matter if i buy a china box with china rom? cant i just select english language on the china rom and flash a global rom myself? Im going to be flashing stuffs anyways
Could really get a good price with just china everything
There are 3 things you should be aware before buying:
1. You'll need to wait some time to unlock the bootloader and change rom (time may vary, it was 10-15 days, then 2 months, I don't know how much right now)
2. If you flash a global rom you cannot lock the bootloader again, unless you want to brick your device
3. There is an announcement by Xiaomi in which they say we will no longer be able to use global rom on china device: I believe nothing really changed and you just have to unlock bootloader to be able to flash anything you want.
Anyway, I have the china version on which I installed the globa rom without trouble, it's working perfectly. Just avoid fake global version, since you need to own the MI account used to unlock the bootloader in case you have troubles with your device.
How many days did you wait to unlock bootloader? So to be safe i need to have a locked bootloader device which is the china version? Because some seller are flashing the global ROM on their own.
I waited 10 days because I installed China beta (otherwise it was 15 days, you don't need to unlock the bootloader to flash same region beta), now it may be different. The answer to the second question is yes, go for China and unlock it yourself. It's gonna be longer but it's safer.

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.

Lock and then unlock "Global" Variant

Hi all,
I had some doubt regarding the so called "Global" variant sold on AliExpress. Is it possible for me to flash the stock Chinese ROM and then lock the bootloader and then later unlock the bootloader and then flash a custom ROM? If yes, my doubt is this, if I wanted to unlock the bootloader after locking it, won't I require the sellers account or whatever he used to unlock the bootloader in the first since that account is linked to the phone?? If so, is there any possible way of removing that associated account and link your own so that it actually becomes your "OWN". Also, does banking apps, say GPay work on an unlocked bootloader???!
Thanks in advance.
Hi, look here Redmi K20 Pro
Read, understand and be careful what you do. I'd NOT recommend locking the bootloader again.

On AliExpress if a listing says global variant, then it's going to be a global model, if it says global ROM, then it's going to be a Chinese model with a global ROM installed by the seller.
You need to make sure you have the Chinese model before flashing the Chinese ROM and locking the bootloader.
It looks like the reputable sellers on AliExpress remove the phones from their Mi accounts, so there is a good chance you'll be able to link the phone to your own account and go through the unlock process yourself.
There's a couple of guides on these K20 Pro subforums to getting GPay to work on an unlocked phone. I'll leave to search them out.

Xiaomi Mi 9T Pro Bootlooder locked

Hi Guys,
I purchsed Xiaomi Mi 9T Pro from Aliexpress with a Global Rom version but the device is a Chinese version.
The seller had to install global firmware and assosiate my device to other Mi account.
The current situation is my bootloader is locked and I can not use the Mi officially to unlock my device.
I tried to contact to the seller, but he can not assist me (they don't know the Mi account access details to release my device).
Duo to that, I tried looking the internet and found this forum. I have a good technic skill so I start tested all the suggestion the forum has to offer.
First I tried ADB and Fastboot, both are failed with the error - FAILED (remote: Token Verify Failed, Reboot the device)
I also tried miflash but he's requesting Mi account that I dont have the device their. I tried to flash a new fastboot but no success.
I really dont know what else to try, I hope someone here can spred some light on my issue from stoping my device to use as doorstops.
Thank you,
Noy
The bootloader cannot be locked to a Chinese device with a Global rom.
There is no Chinese Mi 9 t pro, the Chinese version is the K20 pro.
What is the phone model (my phone/characteristics/model)?

The device stuck on "Main Menu" MIUI Recovery 5.0 so I can not verified the phone model, but according to the seller page the model is: M1903F11A
https://www.aliexpress.com/item/33016509936.html?spm=a2g0o.order_list.order_list_main.61.21ef180253I770
I also tried to use MTK to unlocked the bootloader but I had no success to get the device into a brom mode. I can not trun the phone off, Vol+ & Vol- not works.
Is there any difference between the Mi 9 t pro and the K20 pro?
According to the model number, it is a K20 pro.
Chinese device so the bootloader is locked but with a Chinese rom since this is not possible with a global rom.
Same device except less 4G bands for the K20.
ok this is a start, any advice how to unlock the bootloader?

If the device is linked to an account that is not yours, nothing to do.
Is it a new or used device?
Check with the seller or send the phone back to him.
The device was new when I purchased it, the seller said there is no warranty on the device and he can not do anything about it. they used outsource company to do the installation of the Global ROM.
Surely there is a way to bypass Xiaomi locked on the bootloader. the Kernel can be overwrite somehow. just need to find the right way.

This model is from 2019, seems strange that Ali sells new ones.
And you still don't understand that there can't be a Global rom on this model with the bootloader locked.
The bootloader was not locked when I purchsed the device...

What you are saying now is inconsistent with your original post.
A long story to get to 'lock with fastboot'.
I'm sorry if there was a misunderstanding, here is the long story:
In 2019 I got this device from Aliexpress with a Global Rom version but the device is a Chinese version.
The phone was in English, working well with Google Play, and there was no issues with it.
In few months ago I wanted to start using Google Pay and my credit card was not approved for some reason, I contact google suppport and one of thier questions was "Have you unlocked your bootloader, rooted your device, or installed a custom ROM?"
So I started to google it, I find that my bootloader is unlocked, so I thought that I will need to lock it to be able using the Google pay service. what was found a terrible mistake.
First I understand that the only legal way to unlock it was using the Xiaomi official Mi program to unlock it. what I was found that I need Mi account with a registered device on it. my device is registered on some Chinese guy that I dont know so basically he's the legal owner of my device. so I start to look for an alternative solutions.
In my knolage with programs, I can handle with complex solutions to bypass this issue. but none of my trying wasn't succeeded. as I mentions I tried many was to bypass Xiaomi servers, now I found Miracle Box that promising to do the trick but its for only registered members. also there are some guys that said they can unlock the bootloader for money, but I dont know how trust they are....
I hope some of you guys can lead me to any idea/solution or something....
Thank you all for your time, much appriciated.

So, since 2019 you have used your device without a Xiaomi account, which severely limits Xiaomi services?
never used Xiaomi services...
Try to erase the data with the recovery or safe mode, if the option exists, but anyway if the phone is linked to an account you will be asked for the password.
Accounts are linked with a phone and email number and when you change the number a message is displayed.
Thank you, already tried it...
Is anyone know somthing about this? https://github.com/Canny1913/miunlock
Is the token is the key to success?
To sum up:
You have bricked your phone by locking the bootloader with a Global rom.
The reboot is possible but paying but when the phone reboots Xiaomi will ask you for your account and password.
Never ending Story.

Users who want to flash their phones need to study how to use tools, which ROMs to flash, etc
Eg, when flashing a ROM by Mi Flash, always uncheck relocking of the Bootloader. Then, if anything goes wrong, Bootloader will remain unlocked and one can still flash another ROM to easily unbrick the phone
