Question Lost 5G service on CN Model after I flashed EEA ROM

Hello guys,
Can someone please help me out? I have a CN version MI 11. I live in Greece. 5G was working fine on both my sims while on CN ROM.
I then unlocked my bootloader and flashed the EEA ROM from here : https://c.mi.com/thread-3603220-1-0.html . Unfortunately this broke 5G service on my phone, I can now only connect as 4G+ maximum even though 5G is selected.
Then I flashed Xiaomi.eu ROM ( from here : https://forum.xda-developers.com/t/rom-miui-venus-xiaomi-eu-rom-for-xiaomi-mi-11.4219357/ )thinking that would fix the issue. Unfortunately the problem persists, nothing really changed.
I suspect this is because my Phone Model Name changed on the 1st flash and my service provider no longer recognises my device as a 5G one. My current model number is M2011K2C, however my last google backup was under MI 11.
This is just speculation though, I am not what is causing this.
Can anybody help me please? What do your guys phones list as model name?
PS : both versions of MI 11 support 5G in Greece, see here : https://www.kimovil.com/en/frequency-checker/GR/xiaomi-mi-11?deviceForPrices=xiaomi-mi-11-cn
I don't think you lost 5G, there is a possibility you never had it.
The CN version with the CN rom shows 5G icon even when you don't have 5G, if there is some 5G coverage. It showed 5G for me even when I didn't have 5G access on my sim. The CN Mi 11 isn't compatible with 5G on some carriers, where the global Mi 11 is. Did you do a speed test? Did you actually have 5G speeds? There are other ways to check if you actually have 5G, but I don't remember the apps, you can look into them. As I've said, I had the 5G icon, but the connection was 4G in fact. When I changed the rom, it showed correctly, as in 4G only.

Thanks for the reply. I actually did a speed test while on CN rom, I hit 400mbps so I definitely had 5G service. On my first post I provided a link that shows both CN and Global version of MI 11 support all 5G bands used in my country (Greece).
This is a software issue for sure, I am just not sure what causes it.
Update :
Flashing V12.0.22.0.RKBCNXM CN ROM restores 5G connectivity. It works fine on CN ROM
5G is not working under any other ROM.
Any help would be very much appreciated
I've just purchased Xiaomi mi 11 cn version was looking to flash global ROM but came across your thread.
Is it relatively easy to flash global and back to cn need be?
Thanks

Yes indeed, I did try. Unfortunately it only works under the CN ROM.
This is really frustrating as I dont like the chinese ROM and on top of that I can no longer pass the safetynet test because I unlocked my bootloader.

it is really easy to do. Just remember to NOT, i repeat NOT, use "clean all and lock" option in MiFlash

Have you managed to sort out the 5G issue? No one else mentioned this.
How did you get global version onto CN device? When i tried it says this MIUI version can't be installed on this device
you have to unlock bootloader first, and wait 7 days

Miflash locked the bootloader after flashing EU ROM for some reason. Once I unlocked bootloader again it worked.

I have not solved the problem, I am currently using the CN Rom to get around it but I hate the experience and safetynet fails so I cant use Netflix.
I have seen a few others report this on MI Forums but not many as you say. i doubt any developer will help me.

You wanna say that 5g doesn't work on xiaomi.eu rom despite it derives from CN? Or you didn't try it?

That is correct, I tried both the stable verson and the 12.5 beta version. 5G is not working for me on either one

Another question: Is there anyone who happen to get Google Pay (passed safetynet) on CN rom with unlocked bootloader and magisk? I tried all 3 methods and failed (never get even over basic integrity).

Generaly problem with Message apps is because bad APN (SIM) settings.
What is your Carrier ? Before your Mi 11 / Poco F3 have you VoLTE/VoWiFi activated on your old device ?
What is your Rom, MIUI official or a custom MIUI like Xiaomi.eu / OneOS / MiuiMix ?
Hello again
Ofcause i pay my bills
I've got this problem on my Poco F3 as well.. I live in Denmark, and my mobile company is called Hallo.
I believe that my APN is setup corectly.. when i type this number: * # * # 86583 # * # *
i can manually overwrite the standard settings.. My phone company do support Volte.. But i cant sent any sms with volte enabled??
So i've factory reset the Poco F3, and can recieve but not send messages
Regards
Hello again I've checked all my settings, and they are all correct.. Just for info
regards

Question Network issues in some Carriers Converted OP10 Pro chinese N2210 > N2211/N2213

I bought a oneplus 10 pro chinese version yesterday, and flashed Global Rom and Indian Rom.
My carrier dont work well, the SIM card disappears as if just being taken away, my carrier is CLARO from Brazil, i tested with another 3 SIM cards from the Claro and have same problem. With the VIVO carrier works well, no problems.
I found the same issue in the oneplus forum with the ALTAN carrier from Mexico.
I reversed to Chinese ROM and works well with CLARO.
Has anyone noticed this problem with any carrier?
I flashed android 13 preview n2215 and downgrade to android 12 with rom n2215. Finally solve my problem, works well, 5g in both sim and not sudden deaths more
