If it's not a Chinese handset then yes.
There's 5 hardware regions; EUXM, INXM, RUXM, CNXM and MIXM (Global) - each must be on their corresponding ROM before a relock. Otherwise it's a brick.

I got some doubts.

Hi, i couldn't find a thread like this so if there is any sorry. I'm going to get k20 pro in couple of days, so i got some questions.
Can i install mi 9t pro global rom on k20 pro(i see that xiaomi eu rom is for both k20 pro and 9t pro).
And custom roms(like aosp, pixel) are they compatible with both versions of phones or they are made individually.
I hope you understood what i wanted to ask.

The two phones are essentially the same hardware, and SoC, yes you could potentially flash the mi 9t pro's Rom on the redmi k20 pro.
The Mi 9T Pro is meant for European markets and comes with band 20 that is required for those regions, specifically.
To install ROMs like Pixel Experience or AOSP, they're based on Chinese or Indian firmware, so you'll need to install their respective fastboot ROMs to use them, not at all complicated just look around on the forums, and you'll find guides to install the custom ROMs.

So when i unlock bootloader, can i install trough the twrp global rom that was made for 9t pro? Will there be any problem?
I have mi 5s and im not a total nobby at this but still it looks confusing sometimes.

No idea what a twrp global Rom is, if you want to install twrp, get the unofficial image from here on the forums 3.3.1-15 or whichever is the latest one

Yes, that would be done using mi flash tool and selecting the option clean all and lock, should work if I'm not wrong, would need someone to clarify but it should work

No I would suggest you to use the mi flash tool and download the fastboot rom to get to the global version of miui 10 for k20 pro. You can get it from mifirm (google it), and use the rom in mi flash tool much easier, but you have to have an unlocked bootloader first

Only if you have a global phone. You will hard brick the phone if you try and lock the bootloader after flashing a ROM that is for a different region to the phone. You can only successfully lock the bootloader when the phone has the stock ROM that is for the same region as the phone.

I don't know if we'll get one soon, but TWRP from this thread is by an official TWRP developer.

BIG FAT NO, Your K20 pro bootloader cannot be locked with a Global ROM in it, you'll brick it.

I think the lesson here is,
don't get this phone if you want to re-lock the bootloader after flashing Global ROM.
xiaomi is s-h-i-t at updates.
Just go with OnePlus7/pro/T/T-pro whatever if you value your money, phone and security updates.

The lessons here are.
Don't listen to people who clearly don't know what there talking about.
If you want a locked bootloader and save between $100 - $300 over an new OnePlus phone, then buy the phone for the region your in. European phone in the EU, Indian in India and a global phone for anywhere else.
If you want to save between $200 - $400 over a OnePlus phone and can live with an unlocked bootloader, then buy a Chinese K20 Pro.

Xiaomi isn't actually **** in updates, Indian K20 pro already had Android 10 and MIUI 22 is in the pipeline.

Why would someone re-lock bootloader? I dont see point. I unlocked my mi 5s bootloader 2 years ago and had no problems with it.

The name whether it's k20 pro or mi 9t pro is irrelevant, all depends on the software you want running on it

So there is no need to pay 50$ more for global version while u can put it on chinese one right. Expect for people that dont know much about roms right?

Again as has been mentioned many times, you want to make sure the phone you get is compatible radio, and bandwise to the region you live in.
For example in Canada, the Chinese or Indian Redmi k20 pro, has some of the bands required to run, but msot importantly misses band 20, and a few others that would make it much more well suited.
So for this reason the only version that will work is the Mi 9T Pro, either the global version or the EEA version meant for European markets.
To check for compatibility region wise go to kimovil (google it) and make sure it works in your region. Otherwise it's not really a phone of any use if it doesn't function as one in whatever niche area of the world you may happen to live in.
Do your research, and avoid expensive regrets, good luck :good:

Thank you so much, i couldn't find a site to check 4g compatibility. It says that 4g is 2/3 available (missing B 20) but b3 and b7 are available so i guess i can use 4g.

Miui 11 & android 10

Hi respectful developers,
I bought Redmi K20 Pro from Australia, on the back of the device it is labelled as Redmi K20 pro but in the about phone section it is Mi 9T pro as prior to exporting it to Australia, exporters unlocked the bootloader and installed the global MIUI 10 (see snapshots).
Now the question, will this device in my hand get MIUI11 and Android 10? If yes, when? Will this update revert the device to the Chinese MIUI 11 ROM? If yes, how to get the official global MIUI 11 for the Redmi K20 pro?
I am currently residing in Egypt and would very much appreciate your good technical assistance.
Regards,
Mohamed Atteya
Basically they flashed 9T global ROM in your K20 pro. Which further means the bootloader is unlocked, if yes, you will still get OTAs when they arrive and you will be able to install them, OTA will come of same ROM and not of a different region so rest assured you won't go back to chinese.
HOWEVER. If you will use miflash tool to flash any other region's ROM, MAKE SURE you DON'T check on CLEAN ALL AND LOCK option in bottom right corner. Only check CLEAN ALL. This is because locking a bootloader with different region ROM installed bricks your phone.

Try to change your region to other country like Spain or Germany, reboot your phone and check your system update (updater).

Regarding when you'll get OTA, it will eventually come as per their dates

I'm not sure, you should be in stock recovery if your bootloader is locked, but if you want stock recovery just flash full ROM

Just remember to UNCHECK "clean all and lock" when using flashtool. Check on CLEAN ALL alone.

No, you can not change to a different region with stock recovery. You need to unlock the bootloader and flash the Chinese fastboot ROM with the Mi Flash Tool.

China or global version over Europian one

Hi all,
I have à mi 9t pro europian version, I'm always with miui11
So I want to flash the global version into it via twrp
Is that safe ??
Thanks all
I'd recommend the xiaomi.eu stable/beta roms.
The flashing guide is pretty self explanatory in their site.

for me no different between european and global. i ave global mi9t pro and i have try global european and global and it is all same
So I can flash it without problem
Thanks, that's what I was looking for

Question Is there a way to flash from MIUI China to MIUI Global without unlocking the bootloader

Hi, so i recently got the new Mi 11 and stupid me, i didn't check what version it was and when i booted the phone up, i realized that i got the Chinese version. Due to me having no patience waiting the 7 days to unlock it i cant really use anything. Can someone help me
You have to wait
It is possible - but I do not recommend - you can in EDL mode bypassing xiaomi authorization, you may brick the phone
But to do it hi has to have athorized acout or someone who has It.

The guy on Telegram group who fixed my bricked mi 11 buy flashing through edl told me that he cannot flash a Global rom to my mi 10 with locked bootloader and CN rom. If he cannot do it for mi 10 it is unlikely that he can do it for mi 11.
