So the condition is this:
1. Phone was in bootloop with locked bootloader
2. I used Test Point method to go back to MIUI 9
3. But now I have no IMEI
4. Cannot add the phone to Xiaomi account without IMEI
5. So there is no way to unlock bootloader
Any ideas ?
Same case here
But the phone is operational with stock rom

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
Hi
I have a BIG problem with my P10 (L29C432) on Oreo 365.
Tried downgrade to nougat through Firmware Finder but update failed. Now i have this warning at every reboot.
I have LOCKED bootloader (never rooted phone). And i cant get bootloader unlock code (website not working).
Also cant enter fastboot mode because of that error.
Is there anyway to RESTORE phone with locked bootloader? I have tried to flash previous firmware with sdcard method (hold power,+,- keys) but update fails everytime.
Is there other way to flash new firmware?
I can use phone but at every reboot i get this message?
If there is no other way to flash new firmware than with unlocked bootloader... Where to get code for unlocking bootloader?
Thanks.
Edit:
I can enter fastboot mode but my bootloader is locked.
you have to unlock bootloader by sending all the needed info per email.
you need to send them IMEI, model version, S/N number, and product id and request for bootloader unlocking code this email: [email protected]
next time read about how to rollback to nougat...
Thank you. So I need to unlock bootloader.
Will try to get code.

If you don't have your "product id", you can't have the code for unlock the bootloader :/
The "Product ID" is a code into the system info on android :s
I am waiting for code from Huawei. They will send me code in next days...
you can get product id on imei24. com by typing your imei.
Now i have another problem. I think phone is "dead" now. Unuseable.
Tried to root phone and now nothing works.
Phone does not recognize SIM card at all.
If I go into settings and system information there is no IMEI number?
Can i restore this?
Or need to take it to service center? Or dead phone?
send the device against wall. Buy another one and forget averything about rooting and unlocking bootloader. Its for your safety, trust me.
I have experience with rooting and flashing phones (Sony). Never had problem.
So there is no way to restore phone?
maybe in repair store. Never heard about bricked device without imei. You can still try to flash original firmware.
Hi all,
I've purchased a used P20 Pro from a friend which has an unlocked bootloader and has been previously rooted. I normally keep my phones stock so I want to lock relock the bootloader (I have the code) but despite trying to follow various guides I have been unsuccessful.
Would anyone be able to guide me through the process of relocking the bootloader please?
The main reason I like to keep stock is manufacture updates etc and I don't have the knowledge to maintain a rooted phone.

I don't believe that an unlocked bootloader will prevent you from getting updates. As far as I know the only difference is the warning you get when you boot that "you can't trust the phone."
IF YOU BRICK YOUR PHONE IT'S YOUR RESPONSIBILITY
Don't know if there is another way but of you have fastboot and adb you can do it:
1. Make sure developer options are enabled
2. Connect your phone to the computer using USB cable.
3. Open a command window and type 'adb boot bootloader'
4. Once the device has booted into the bootloader mode type 'fastboot oem lock'
This WILL ERASE all your user data and you will have to configure everything from scratch. You will need the unlock code if you ever want to unlock it again so make sure you don't loose it.
Hello, I have a few questions about flashing rom just to make sure I wouldn't end up in EDL mode again. First, let me tell something. I have bought my K20 pro on Aliexpress which come with a firmware that mark as MI 9T pro with bootloader unlocked but without TWRP install. I have tried to flash Android Q beta though fastboot without using the option Flash & Lock but i was end up in locked bootloader and then i got it fixed through EDL mode by paying someone from Russia who i don't know the name. Later on, I got another bad luck again by upgrading my official Chinese firmware through OTA and then the phone suddenly shutdown in the middle of the process which break both my recovery and fastboot so i have to go through EDL again. So, my questions are:
1. If i flash anything such as magisk, viper, or upgrade my xiaomi.eu firmware through TWRP, will something like my second story occur again? Or, does flashing through TWRP will brick both recovery and fastboot in the same or similar case?
2. After EDL mode, bootloader was unlocked by default so, what can I do to bind my MI account with the device? Because in case it locked again, then I can use xiaomi bootloader unlock tools to unlock it. In the first story, the device come with bootloader unlocked, and after flashed Android Q beta, the bootloader was triggered and locked so then I tried to unlocked it but Xiaomi bootloader unlock tools told me that my account is not bind to this device.
3. If i flash magisk, then do i need to always re-flash it on every system upgrade(xiaomi eu firmware)?

1. In theory flashing with TWRP shouldn't touch the fastboot or recovery partitions, unless you choose to. If you know what you're doing, then flashing with TWRP is reasonably safe.
2. You could try flashing an official Chinese fastboot ROM and locking the bootloader, then link it to your account. Don't try and install anything else, live with the official Chinese ROM and go through the normal unlock process. Once you've waited and got unlock permission for the phone against your Mi account, then unlock and install the ROM of your choice along with anything else.
But this does come with a small risk that the phone is still linked to the sellers account.
3. I went straight from stock to a GSI, so not sure about eu ROMs. If they have an OTA process that downloads then installs via TWRP (similar to official LOS), then it's possible Magisk will re-install at the same time. Someone who uses eu ROMs will need to confirm what happens.
For anything else, you'll needed to re-install Magisk.

I believe it is a risky method because if the bootloader is locked the phone might brick again and I have to do EDL again too. I wish if there is a safer method, because I experienced EDL mode twice already and it is terrible and need to pay lot of money just to fix it. :crying:

Flashing an official fastboot ROM in the Mi Flash Tool and selecting 'clean all and lock' "shouldn't" brick the phone. If you're on an official Chinese ROM, then going through the standard unlock process "shouldn't" brick the phone.
The biggest risk in doing this would be finding that the phone is still linked to the sellers account.
If you want to be able to unlock the bootloader with your own Mi account, should it get locked again, then this is your only option.
However, you could leave it as it is and just make sure you never lock it again.

I see. It's too bad to get an unlocked phone. I will need to be more careful next time buying a new phone.
hey guys can someone please help me? I already unlocked my phone once but it soft bricked, when after flashing the firmware and the phone booted back to system it didn't have the IMEIS anymore, so I looked for weys to restore my imei but I need the bootloader to be unlocked again, but when I enter to mi unlock status the account won't stay as shown on screenshots.
