Downgrade (ARB) - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello. Is Antirollback present in Mi 9T Pro? I am on MIUI Global 11.0.2.0 and I would like to flash MIUI EEA 10.3.4.0 (so downgrade from MIUI 11 Android 10 to MIUI 10 Android 9) will it brick the phone when I downgrade and RE-LOCK THE BOOTLOADER?

No, there's no ARB on this phone. However you can only re-lock the bootloader when flashing a ROM that's the same region as the phone. So, if the phone is an EEA phone that came originally with EEA MIUI, then you should be good to flash and re-lock.

Going back to EEA Rom with locked bootloader ?

Hey everyone
I ordered my Mi 9 on Amazon and received it two days ago. When I used it for the first time, I noticed it was running on MIUI Global 10.2.28.0 (which is the EEA version).
After messing a bit with ROM flashing I ended up flashing a Global ROM over the EEA one with XiaoMi Tool V2, all that with locked bootloader (I can't unlock it yet).
The problem is that right now I can't flash the EEA ROM over the Global one, it says that my version is illegal or that I can only flash new firmwares.
Is there a way to get back to the EEA ROM without unlocking the bootloader?
EDIT : I've found my answer, I can't. I'll wait to unlock my bootloader and install the Xiaomi.eu ROM since I'm living in an EEA country

Yes, should be possible. Just download the Firmware package for your Device and flash it through the Mi Flash tool.
Before you flash though, make sure to download the Firmware according to your Device / Region. Also if you don't wanna lock the Bootloader, uncheck the "FLASH ALL AND LOCK" Option first.
IN is for Indian Devices
CN for Chinese
EEA for Europe
GLOBAL is basically "for the rest of the world"
Hope that helps

Question Problem with choosing fastboot rom

I want to install magisk using adb.
My miui build is V14.0.2.0.TKFEUXM GLOBAL but the only available rom from miui updater with this number is Redmi Note 10 Pro EEA.
It is the same rom? And what does it mean EEA.
Also is it possible to get boot.img from my rom using adb command?
global and EEA are basicly the same thing, you will not notice any changes. EEA is for europe.
