Flash Official Full ROM without unlocking bootloader

How can I flash MIUI 9 Official Full ROM without unlocking the bootloader?
I pressed the ”OEM Unlocking” without unlocking the bootloader. I didn't even enter the approved account in "Mi unlock status". Now the status is unlocked. The bootloader is actually still locked. When I use PC to unlock bootloader, it goes until 99% and gives me the error "Current account is not bound to this device". I tried resetting the phone from settings (wipe data partition) but the status is still unlocked.
The question is how can I undo the status to locked so that I can continue unlocking this device and enter the approved account to "Mi unlock status"?

Apply for permission, wait to receive confirmation, sign into account on phone and on Mi unlock tool. Bit too Fastboot mode, on Mi-unlock tool it gets to 99% and then should give you a message to wait 360 hours. This is correct, it will work after the amount of time (about 2 weeks).

Thanks,
But this problem got even worse. I updated to MIUI 9.5 from MIUI 9.1. The update failed. It is not possible to boot into Android either. I even tried formating data. The bootloader is locked. I applied permission and already received it.
I bought the phone via China Mobile.
I suspect that my ROM may be a fake one. But it looks totaly original.
1. 4 digit version code
2. NCKMIEI --> Official and correct MIUI 9.1 version
3. Gapps preinstalled
4. No bloatware
5. Everything looks the same like the original ROM
6. Even Mi Remote is working
What I'm thinking about now is how is the Mi status "Unlocked" even I didn't even enter the approved Mi account used to unlock the bootloader.
I know the bootloader is really "locked" because

I'm currently trying to flash CN MIUI ROM through EDL mode (test point) because Global ROM failed. Then try to unlock bootloader from CN MIUI ROM and re-flash Global ROM through MiFlash

Okay, so the phone runs fine now. The phone now runs CN MIUI 9 9.5.3.0 stable version. I am still waiting for the 360 hours (15 days) man!!! for the bootloader unlocking. I applied for the unlocking. Will update when I successfully return to Global Stable ROM.
I flashed CN MIUI 9 ROM via test point. When it reboots, it will show you the error you've encountered before. Relax! Just reboot and wait for about 15 minutes and your phone is alive again.
Thanks Xiaomi for the INCREDIBLY TIGHT SECURITY ???

There is some risk you have to take in order to flash via EDL (test point) mode.
1. You have to backup all of your data. When you flash via EDL mode, your phone will return to "stock" like when you first buy the phone.
2. Flashing via EDL mode will involve removing the phone's back cover. You have to do this if you really want to flash via EDL mode.

Yes. You can unlock bootloader after flashing with EDL mode.

Only use China ROM if you bought your phone from China. If your phone is International phone / not bought from China, I advice you to flash Global ROM first. If it doesn't work, then try China ROM.

Have you tried a different account? Try registering a new account and don't change anything. Then apply unlock bootloader permission at https://en.miui.com/unlock/. After applying for permission, enter your account details in Mi Unlock Status.
If you have a PC, download Mi Unlock Tool here: http://miuirom.xiaomi.com/rom/u265827351/2.3.803.10/miflash_unlock-en-2.3.803.10.zip
Open Mi Unlock Tool by clicking miflash_unlock.exe.
Enter your login details and reboot your phone to fastboot mode.
Plug in your phone.
Press unlock.
If successful, you will see a message with "After 360 hours of trying to unlock device"
This is normal.
You need to wait for 15 days to try to unlock the bootloader.
There is no quicker way to overcome this. I also waited for 15 days. Also please don't keep pressing unlock in your PC when the 15 days is not over. It will block your device and you can't unlock again.
If you need some personal assistance, private message me and I will give you my Facebook / Messenger ID.

Mi Max 3 Bootloader Unlocked... next steps please.

My bootloader was unlocked via official methods.
My Mi Max 3 is the China version with latest 10.0.0.6.0 rom installed
I want to go over to the Global rom for now, can I install 10.0.0.1.0 (miui_MIMAX3Global_V10.0.1.0.OEDMIFH_220b8e8eab_8.1.zip) without causing any ARB triggers or problems?

You need to download the fastboot IMG not the recovery one. Go here for instructions https://en.miui.com/a-234.html

And it's really important that you don't relock your bootloader, because that bricks your phone. In MiFlash you must select the 'Clean all' option in the bottom right corner.

If you don't want any ARB issues, I recommend following my buggy vendor rom thread in the guides section. Unless you're bootloader locked, I don't see any reason for choosing global over xiaomi.eu roms.

Hello,
I have a global version of Mi Max 3 and MIUI 9.6.7 is installed. I unlocked bootloader with official method. I haven't done anything but temporarily booting TWRP with fastboot method. I haven't flashed TWRP or rooted phone yet.
I noticed Mi Max 3 started to boot very slow after unlocking bootloader. It started to stuck nearly 2 minutes on screen that writes "unlocked". It takes 3 minutes to reboot the phone. And I experienced several hangs, crashes and resets itself after bootloader unlocked. Are there any other people experience similar problems with this phone after unlocking bootloader?
If I re-lock the bootloader without touching anything (without installing TWRP, root, or upgrade current MIUI), is there any possibility to brick Mi Max 3?
Thanks for help

Locked bootloader, stuck in recovery mode.

Hello guys.
I recently bought this phone and wanted to use netflix, but didn't allow me because it outdated and said it was not compatible with my phone. So I did a bit of research and found a post in "mi community" that said it was because phone had bootloader unlocked. The phone was new and I didn't change anything of it, but I found the bootloader was unlocked.
Installed fastboot and adb drivers, locked bootloader and got myself into a... Brick?
-I can still load into fastboot.
-If I turn on the phone, It tries to load android but loads Mi-Recovery 3.0 instead. Recovery also says "This MIUI version can't be installed on this device"
I'm so lost from this point, I need to know if there is a way to flash any rom, and which one do I need.
Thanks in advice

stuck on recovery
Most likely a chinese phone that came with global rom. If it came with global rom try flashing chinese rom and then unlocking bootloader and reflash global. Do not lock bootloader after flashing global.

Thanks for your answer, that is exactly what I've.
The problem is I tried to flash a Chinese from but it always denie it. Tried to flash the last global rom and allows me to do it with the same program.
Not sure where I can get the official chinese rom or how to bypass the xiaomi protection.
Thanks for helping! Hope I can somehow do it

Try searching for tools below which might help.
Saki / XiaomiADBFastbootTools

I had hard bricked mine and had to take back off and use EDL to revive.

I don't find the way to reboot (via software) to EDL from fastboot, is still possible to access it by opening the phone?

If you can flash global ROM. I think you just need to unlock bootloader and then flash China ROM once you have unlocked bootloader.

It lets me flash de global one, but when I try to do the same with chinese rom, it says the version is lower, so I can't "downgrade".
It's weird because according to version number, the global one was a few versions lower

Solved the issue
The same issue , i was also encountered , After Flashing with "Xiaomi_Mi_Max_3_V10.2.1.0.PEDMIXM_20190226.0000.00_Global_9.0" Mi Max 3 with the MiFlash20191206 tool , by default the tool used "Clear data and Lock".
The tool saying "Flashing" and my phone got rebooted and went to MI Recovery 3.0 and also i got the message as
"This MIUI version can't be installed on this device".
I am not clueless how to proceed. So downloaded the Chinese version and again i tried to flash with above tool. Now tool said that "Can't Erase Locked" phone.
So Now i connected to Miflash_unlock with fastboot and connected to mi account and again i unlocked the phone.
Now my phone automatically booted to the Global version.
So i hope the issue is selecting the option as "Clear data and lock" . We need to select only "Clear data" in the flash tool.

Hi there,
I encountered the same issue. I tried to flash some CN Rom without enough research, without knowing that you can't just flash an Android 10 rom from 9 directly by recovery (even TWRP). So I ended up Fastboot or TWRP but never able to boot into system. Fortunately I didn't flash my Max3 by fastboot rushly, so my phone was still unlocked.
This is how I solved it:
1. Download an official CN ROM (the below I used is MIUI 11 with Android 9.9.x);
I can't post link here but search "miui通过线刷升级" - you shall see a miui.com link ending with shuaji-393.html. That's the page I download the Mi Max3 ROM from.
2. Use MiFlash to flash the official ROM with the flash option "clean all", NOT "clean All and lock";
3. The phone shall reboot into system, give it 5-10 minutes;
4. Flash the miui.eu ROM you like (DO make sure it is Android 9 tho) by recovery (tutorial given under every official xiaomi.eu ROM download).
Again it's easy to search
It took me less than an hour to do it (I don't have much experience with new XiaoMi phone). So don't worry about bricking your phone forever.
Hope it helps to destress

Hi guys. I need some help too because I'm not totally sure what I have to do here so if anyone can give me some tips I would appreciate it.
I just ordered the 128gb 6gb ram version of Mi Max 3 and it might come with the global rom and already unlocked. Should I use the Mi flash tool to install the file MIUI 11 V11.0.3.0.PEDCNXM android 9 fastboot file? then after that installs I should lock the bootloader and then unlock it again myself with my mi own account? I just want to make sure that this is the correct way to do it.
Also after it I unlock it should I flash the newest xiaomi.eu rom with android 10 or do i have to do something else first? Thank you

Firstly, you shouldn't re-lock your device while you are running something "custom" on it.
And in case you switched from Chinese to Global, no matter that it is a stock one, neither.
You should completely return to stock and re-lock device either through fastboot commands or using the option "Flash all and lock" through Mi Flash tool.

technically it is possible to relock the bl on some phones and some roms (graphene os for example)
the process is ... let's say complicated. and risky.
as subway said, no do not try to relock if you want to run a custom rom.

Thanx Dear,
i found the problem, its in Magisk, i disable it and every thing goes normal

Can I flash a global version ROM to a Redmi Note 8 Pro CN version?

Hello all,
As a consequence of a recent OTA update to MIUI 12.5.2, Google Play and Google apps ceased to work on my Redmi Note 8 Pro (begonia) CN version. In order to have them back again, I am considering switching to a stock ROM for the global version of the RN8Pro.
Does this sound like a reasonable plan?
Are there hardware differences between the CN version and the global version of the RN8Pro?
Can I go ahead and flash a global version ROM over a CN version ROM?
Would this allow me to install Google Play and Google apps on the RN8Pro?
Thanks!

You can. You are not asking for impossible. But it will cost you your data as your phone will be wiped in the process.
The procedure is Unlock bootloader -> Flash Global/EEA/Indonesia/Xiaomi.eu ROM (but the guys at xiaomi.eu stopped the development of the ROM long ago, so only ancient version of MIUI is available) OR even a custom ROM (wichever you like). You will find the corresponding tutorial in this device's forum.

@kekesed97: Thanks!

After a one-week wait (Xiaomi imposes this waiting period for bootloader unlocking), I was able to unlock the bootloader and flash a stock global ROM to my RN8Pro. Everything went fine. The phone was working perfectly, with its bootloader still unlocked.
Then I fell into a trap.
After reading about things that would not work on a phone with unlocked bootloader (Google Pay, banking apps, etc.), I decided to relock the bootloader of my RN8Pro. Did that by running "fastboot oem lock" on a PC connected to the phone.
Relocking the bootloader kind of bricked the phone. The RN8Pro is now stuck in the menu for "MIUI Recovery 5.0", with the following message at the bottom of the screen:
"This MIUI version can't be installed on this device"
Is there a way out of this trap?

Some GooglePay and banking apps can be used after pass safetynet by doing something with Magisk. And you should read something about lock bootloader before doing that. China phone only can be locked with China Miui roms, by chose clean and lock on Miflashtool (best way to prevent brick). So if you want to do that, better downgrade to Miui 12.0.x to use Google apps and no more updates. And if anything else you want to be helped, join group on Telegram and get help.

Thanks, @Kirasu2080. Now I see that I should have flashed a MIUI 12.0.x China version ROM, rather than a global ROM.
But I still don't see how to fix things... Since phone is stuck in recovery with its bootloader locked, it appears as there is no way for me to downgrade now.

Use free unbrick hardbrick method for this. You can search Youtube videos, some solve problems, some not work, some make you lose Imei. That's why i told you join Telegram group for direct chat.

I have the global vesrsion of the Redmi note 8 pro. I want to flash the Euro version on it without unlocking the bootloader. Is this possible with the MiFlash tool?

You need to do the "EDL mode or Test point".
Lock xiaomi devices can be unbricked using that method.
Flash firmware using EDL or Test point mode. Please search in youtube.
