Global ROM Version for Mi 9 SE

Hello,
I have an question. I recently bought Mi 9 SE Global version from a local store. I received an update (Stable) which is 485 MB sized.
My ROM version is: 10.2.2.0 (PFBMIXM)
why is it different than global ROM version which found in this forum: PFBEUXM ? I heard that PFBEUXM is EU/Spanish variant.
So How can I ensure my phone has real global version ROM? what type of global ROM is it?
Any information Guys?
My Region is: Bangladesh
hi , 10.2.2.0 PFBMIXM is global internationnal rom , PFBEUXM is for europe , same rom but some differents for privacy tracking, no chinese apps, and some others things, now stable version is v10.2.9.0, the 10.3.3.1 have issue , brick phone after ota update and update is suspended
all last updated rom => https://mirom.ezbox.idv.tw/en/phone/grus/
it's clear now, but where is that 10.2.9 update? why i didn't get it yet? is it for region?
even your given link don't have that ROM download link..
The 10.2.9.0 update is for EU version, your model is stuck at 10.2.2.0 until Xiaomi rolls out the 10.3.1.0 again, which has caused a lot of problems.

Question EEA TO GLOBAL

Hi. I recently purchased a POCO F3 on amazon version EEA RKHEUXM (NOT THE CHINESE VERSION). However, the seller had assured me that it was the Global MI version (RKHMIXM). WHICH IS NOT THE CASE.
However I would like to know if it is possible to change EEA to Version (GLOBAL MI) without unlocking the bootloader. I saw that some people did it with XiaoMiTool V2. Since I live in Brazil, it is more advantageous for me to have the Global version and not the EU global version.
I know it's impossible without unlocking the bootloader if it's Chinese version (again, not my case).
So does anyone know if it is possible to switch from eea to global without unlocking bootloader? And if I need to unlock, can I lock after putting the GLOBAL ROM (MI) WITHOUT HARDBRICK?
Sorry for the bad English.

This is so weird... I saw it right here on XDA. Some people can do it with XiaoMi Tool V2, while others don't, I'm confused... In that case then, when unlocking and flashing the global rom, can I lock the bootloader normally?
You cannot relock the bootloader on a region which was not originally installed on the device. Consequently, you have to unlock to flash any other version than your original.
Anyone who has tested from EAA rom to GLOBAL?

You can unlock bootloader, flash global rom and then relock bootloader.

Would you have a step by step please?
Unlocking bootloader by exiting the EEA rom and installing the GLOBAL ROM and lock the bootloader again.
If possible. And why did the other user above say I can't lock the bootloader if it's not the original rom? as far as I know it's only when it's from the Chinese version to the global one, right?
I changed from EEA to ID (Indonesia) and locked the bootloader without issues. using MiFlash tool. To unlock, use Mi unlock tool....it will take aprox 7 days if u unlock it for the first time. But it's ur decision if u take the risk or not after all.

Its possible without unlocking the bootloader I just did it yesterday on my Poco X3 Pro, from 12.5.2.0 EEA to 12.5.5.0 Global. In the XiaomiToolV2 selecting official rom didnt work for me (told me that unlocking is requirement) but the option to use Local Miui Rom file in the tool worked and it flashed

Question Query regarding OS Downgrade on Poco F4

True to my knowledge, if the Rollback Index of the Fastboot ROM is less than the current device rollback index, then we cannot flash that ROM as it will trigger Anti Rollback Mechanism, which might end up hard-bricking the device.
In my case as well, my Poco F4 running Android 13 has an ARB of 1 whereas the Android 12 Fastboot ROM that I have has an ARB value of 0, so this means downgrading should not be possible.
However, I have seen across other Xiaomi device forums on XDA wherein users did manage to perform a downgrade simply by flashing the downgrade firmware via Mi Flash Tool.
So is there something specific going on with Poco F4 or I'm missing a point there? Any insights on the same will be highly appreciated.
Don't worry about downgrading OS version from 13 to 12, you just need UBL... and you can flash ROM from anywhere, global, EU, Thailand and more.
Jangan khawatir tentang menurunkan versi OS dari 13 ke 12, Anda hanya perlu UBL ... dan Anda dapat mem-flash ROM dari mana saja, global, UE, Thailand, dan lainnya.

Well, this is what I knew in theory as well. But in practice that doesn't seem to be the case. Aa far as I know, you could only flash a ROM if its Anti Rollback [ARB] Index is equal to or greater than your device's ARB.
And after updating my Poco F4 to Android 13, its ARB is now 1. On the other hand, all the Fastboot ROMs that I have tried to date [Android 12, Android 13, Global, India, etc] have the ARB 0 and hence they all refuse to flash due to the rollback index. Just to be double sure, I took the risk and proceeded ahead to flash them, but the Mi Flash Tool straightaway refused it due to ARB.
So is there any other way out of getting this job done? Because as of now, I could only go from one custom ROM to another, but cannot flash the stock Fastboot ROM. [And yes, my bootloader is unlocked throughout the process].
let me know your failure image I will tell you the lines you have to remove so that it doesn't fail on flash.
beri tahu saya gambar kegagalan Anda Saya akan memberi tahu Anda garis yang harus Anda hapus agar tidak gagal saat flash
