Can I change rom region, from AA to BA? - OnePlus 8T Questions & Answers

I have 8t chinese version KB2000 with 11.0.4.5 KB05AA rom on it. I got phone with this rom version, so somebody changed rom from HydrogenOS to OxygenOS...
My question is, can I download EU rom, KB05BA version and just upgrade to new rom with stock updater, option local update? So can I that way change rom region?
Do I need to do that? Is there any diference with those two roms?
I live in EU, that is reason of my question...

Yes, you can via local upgrade. Not much difference in the ROMs. You might have a hard time going back to AA in the future if no full OTA is released. You don't get additional LTE/5G bands by flashing a different region ROM.

I know, additional LTE/5G bands are bound to hardware... I'm OK with that...
So I can change region to EU, that is good to know... I ask specifically because AA full rom zip is not available, but BA rom is, if accidentally needed...
Thank you!

Dont do that ! Coz you cant go back from AA to BA at now. My 8T was on AA and worked wery well and rom was completly with all of OP apps and function when i changed to BA i lost many widgets, apps and functions.
Can you make backup of your AA rom ? Maby can you download your AA rom with Oxygen Updater at now before changing to BA.

You can use the MSM tool in the forum to go back from BA to AA, just did it the other day.

There is no AA full rom zip in Oxygen Updater... I am still on AA...
Which apps you lose, which functions?

I am using BA (Euro) rom on my KB2000 phone (purchased in China). I transferred all apps and data from my 7t and no any issue was found so far. However, I am unable to test the 5G connectivity as it is not available yet in my city.
When AA full rom is available, I will change to it as I think AA rom works best for KB2000 phone.

GM1900 comes officially with HydrogenOS. And no, the updates aren't the same.
To convert to global you just need to install OxygenOS with official updater app. And you are good to go. You also won't have limitations than.
To install OxygenOS download the update zip HERE!
2. copy it to the root of internal storage
3. Go to settings, system and system updates.
4. Press the settings icon
5. Local update and choose the OxygenOS update.zip
6. Let it install and reboot after that.

If you wanna stay on stock ROM, just use MiFlash (check the "clean all" option on the bottom) and fastboot ROM for Global version you wanna use. You don't need custom recovery.

Please note MIUI.EU and EU region firmware is difference. MIUI.EU based in global firmware code MI. EU region is EEA with EU firmware code. don't get it wrong.
1. Miui.eu is better for me with less bloatware and still keep miui feature. Use since mi 6x and old poco f1.
2. Indonesian language include in miui.eu
If you want try it UBL and flash global first with MI code firmware last version. Step in Miui.eu rom thread.

sure :good:
You can but it's not recommended. Different rom regions use different persist.img (use a hex editor to read it). A different persist.img has different data offsets and it can mess with things like Mi account, compass and different sensors, activation data etc.
Le:fastboot won't flash persist.img even if it's present in the ROM folder. You can flash persist.img from twrp but again, not recommended to flash another version of it.

So, you will try to flash global ROM after getting bootloader unlocked?
My main issue now in 12.0.1 is the dynamic refresh rate or something like that makes gaming experience like a crap as hell even if i stay in fixed 60Hz refresh rate

Just saw an update for ID ROM to 12.0.3 from 12.0.2 (https://t.me/s/miui12_official). So, I guess it was a 12.0.2 update too

I don't believe the global rom is out yet we've been the EU version
Received my 8T from ali with Global 11.0.3.4KB05AA and so fast to fast downloaded Oxygen Updater and downloaded 11.0.4.5KB05BA without doing backup or download 11.0.3.4.KB05AA​ with OUpdater
I need 11.0.4.5KB05AA but could be any other version but AA - Global/International
What is Your version ?
There is no 11.0.4.5 KB05AA full rom in Oxygen Updater yet... only incremental package 107mb....
I am using the 11.0.4.5.KB05BA on my KB2000 and so far everything works fine. Awaiting for International Rom.
I am using 11.04.5.KB05AA on my KB2000, but I after first boot I upgraded my phone from system menu, not from Oxygen Updater...
Is AA version internacional version? What is diference betwen those version, AA, BA etc and KB2000 vs KB2001 etc?

His is probably a hacked aliexpress phone. I seen a few ppl posting that they have issues updating it and factory restore reinstall hydrogen instead of oxygen
My phone was bought in Hungary, so I relly do not know which rom was on phone before I got the phone, does someone installed AA rom or something else.... When I got phone, AA rom was on phone, and I updated to 0.4.5 with stock updater...
Now I'm waiting for new rom and I will see is there any problem....

Yea, that's one of those hacked aliexpress type phones. Your phone is a china model and originally came with hydrogenos, before the seller hack the global AA rom onto it.

For now, there is no problem with phone, everything works as expected , so yes, you can use global rom on KB2000...
OxygenUpdater see my phone like "oneplus 8t", no EU, NA or any other variant, and everything is OK...

That's good that it's working. it's hacked because the full global rom that you can install does not exist.
They installed older rom, which maybe exists, than I updated to 0.4.5.... I know there is no full AA rom to download yet...

AliExpress sellers always get the global rom zips, even before its released to public. I have seen with Xiaomi phones and OnePlus phones. No idea how they do it.
Alright fellas who is a trusted and reputable seller in Allixpress to buy the oneplus 8t global version or global rom..? Fast delivery if possible ?

I have KB2000 and the installed OS is Indian Release

Question Is it possible to change the "software build" of my phone?

I bought a OP9 chinese model LE2110, my software is oxygen OS 11.2.3.3 LE25DA (indian)
I want global version because this one has some bloatware and indian company cloud notifications that i dont want.
Is it possible to change it to international version? i downloaded the global one but i cant install it (local) because its a downgrade or equal to my current one. i updated to the latest version when setting up my phone.
The chinese version/model doesnt have wireless charging, so if there is a problem with compatability, can I change back to the indian variant?
note: I dont care about my data i can format everything, my old phone can transfer things for me later
sorry i am kinda new to this

My bad.
Well the answer I got is that I can wait for the next update, and manually download the european/international version(build) from Oneplus website. It will install and replace the indian version, and supposedly I will be able to remove all the bloatware that I can't install. I can't install the current international build because it is the same number as my current one and its considered downgrading, which is not allowed.
So I will wait for the next update and download it manually. Hopefully this works.

Pro tip: disable auto downloading the software update over wifi, just so that you don't accidentally download it.

Stock ROM from a different region

Hello all,
I own a Poco X3 NFC, I bought it in Italy, but discovered later (after I installed MIUI Downloader) that my phone falls under the Turkey barnch (RJGTRXM).
No problem, but I would prefer to move it under the Global (RJGMIXM) or EEA RJGEUXM) branch, since they seems to be more advanced.
This is because last OTA ROM version has few bug and draws battery really fast.
My question is: can I download the latest ROM from a different region and update the phone with it?
I don't want to factory reset my phone, I would like to keep all my installed apps: is it feasible with a different ROM?
In other words, would a dirty update work with different region ROM?
I would prefer to use the internal MIUI updater, but if I need to use the recovery, no problem at all.
The onlt request is to do not reset the phone.
Thank you in advance.
Ciao,
Giovanni

To change rom version, you must unlock the bootloader, this action will erase your data.
https://c.mi.com/thread-2262302-1-0.html
You can restore some of your data using: Micloud, MiPhone assistant, google, third-party apps.
After the 168 hours of waiting use this tool:
