Mi 8 se unlocked bootloader help - Xiaomi Mi 8 SE Questions & Answers

Hello there,
A very bad thing happened to me unintentionally. I request your help in this matter.
I think I made two mistakes while flashing the rom on my Mi 8 SE phone. My 1st mistake was throwing chinese rom. My second mistake is that the phone locked the bootloader while flashing.
Now the phone turns on but there is no network. I cannot unlock the Bootloader because there is no mobile network. Because when I say unlock bootloader from developer options, it asks me to turn off wifi and connect with mobile. But I can't use mobile data because there is no network. I thought I'd assign a modem file, because the bootloader is unlocked, I can't install twrp with fastboot either. I look forward to your immediate opinion on this matter. Thank you.

I am sorry to hear that,you can buy a Chinese phone card

[HELP] Unlock Bootloader without Mi Account

Hey guys
this is my first time using MUIU
I brought a MI MAX 2 from a guy that i met during an event.
He told me that he doent remember the password and brought another phone
as i know about twrp and blabla
i brought it with a low price, but i'm able to bypass the mi account but since i get online it locks. (Now i'm thinking its stole)
i was able to go to dev options and enable OEM Unlock and USB DEBUG.
with this can i flash twrp? or something to get rid off the miui account?
The whole purpose of bootloader and the Mi Account is to keep your phone safe. So, without Mi Account, you can't unlock the bootloader and vice versa. EDIT: Also, he doesn't remember the password is completely stupid, becuase when you create a Mi account you need a mobile phone number and E-mail, so you can approve your account, and also in case of somehow magicaly loosing the password, you can recover it by using the data you provide while creating an account.
but since i have OEM UNLOCK option means that my bootloader is unlocked?

to be sure if the phone is unlocked, check the phone while it is rebooting. if you see the word "unlocked" at the center/bottom part of the phone, then you're in luck, but otherwise, then no go for twrp.

No, it doesn't. As already a member wrote to you, you would have "Unlocked" word, under the logo when you turn on your phone. IF that is a case, than your phone is unlocked already, if there is nothing, then sorry.
You can bypass account using MiracleBox, you can watch it on youtube.

Thank you very much for help. I have read both but unfortunately i can not UNLOCK my bootloader… when i was trying to unlock the bootloader through MI UNLOCK, it says "Current account is not bound to this device". Otherwise if this was succesful and i could unlock it, then it would be easy i believe.

Since you locked the boot loader, you'd have to flash (with fastboot) using the same flavor of miui which was installed. (example: chinese or eu variation), otherwise you won't be able to boot.

Yes, that i understood… There was EU variation with unlocked bootloader, which i do not know why, but okay…
But now i can not unlock it, it says, when i try to unlock it though fastboot with mi unlock, it says "Current acount is not bound to this device, ADD your acount and device in MIUI"s setting > developer options> mi unlock status.. but obviously i can not do it since i can not turn on my phone, its stuck on recovery mode.

I can help you
First of all you need chinese mi assistant
Second you need try three versions of roms(eeu , china , global) but im pretty sure that your phone is chinese version that bought from gray market and they unlock bootloader to install global rom
After you download these tell me, i guide you
Be sure download recovery rom (not fastboot)
It has .zip extension not tgz

If you know how to sideload the rom then everything is become okay dont worry
After successful debrick you must bound you mi account to your phone and wait for bl unlock then reflash with mi flash tool and global rom
AND DONT LOCK YOUR BOOTLOADER AGAIN
Yes, unfortunately i do not know how to sidload the rom... But when i have Chinese rom downloaded then what do i do with that? I connect the phone through mi assistant and there it can be flashed?
I had the same thing happen. You need to force a firmware flash ?
I had someone on xda recommend an excellent recovery tool.
It's called 'miflashpro'. It can be hard to find the English version. I did eventually but actually unbricked my Mi9 with the Italian version.
99% chance your cell can be fixed this way
bricked too
I'm having the same problem here, after wipe in twrp mode my phone restart and i'm blocked on bootloader screen.

I did the same thing with a Mi CC9 relocked the bootloader by mistake thinking it was like any other android phone. Did you have a Xiaomi account associated with the phone and signed into after enabling oem unlock in developer options.
If tha'ts the case you can use https://en.miui.com/unlock/ tool from where but it checks your phone number to see whether its associated with mi unlock.
Otherwise you will have to use EDL method which involves disassembling back of phone and shorting out two pins to initialize EDL data transfer but you need a EDL associated account this (belief xiaomi has revoked everyone access to these)

If you are still stuck, try to install the fastboot EU ROM or install TWRP and flash the EU stable or weekly. With the Chinese version it requires you to connect with your sim to compare imea number and account phone number. The EU version doesn't ask. It might get you out of a fix.
Just be warned that if your phone was affected by the radio going off during any official proceedure, you may have corrupted your persist.img file. I'm not sure if there is any way back if you have other than may be an EDL reflash or a trip to a service center. If you are really stuck, go down the EU ROM first, then EDL before sending it off unless you can claim on its warranty.

Maibe if U put another sim. Even so, imei remains the same. I think phone data will be recognised by XI if U try to make another account.

Since you locked bootloader and phone is not bootable, you need to look for someone with EDL account (they will charge).
I don't know anybody but search through similar threads for various Xiaomi phones

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,

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.

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
