I live in Europe, and a friend from China bought me a Xiaomi 14 Ultra. However, due to system restrictions, I cannot use Google services. Could you please tell me where I can find services for unlocking and flashing the device? Can the EEA system be used normally in Europe? What are the differences between the EEA system and the Chinese system on my device?
 
Don't confuse EEA ROM with xiaomi.eu custom ROM.

- If you install the EEA ROM on a CN device, for example GPay (NFC payments) and the like will not work. The reason will be an unlocked bootloader.
- If you install the xiaomi.eu ROM you will bypass this limitation. I recommend installing the xiaomi.eu ROM.
The first thing you need to do is unlock the bootloader (search for a paid service, for example NCUNLOCK).

Once you have the bootloader unlocked, you can follow this guide from point 3:

"If you install the EEA ROM on a CN device, for example GPay (NFC payments) and the like will not work. The reason will be an unlocked bootloader."

1. What if I install the EEA ROM and lock the bootloader again than the GPay (NFC payments) would work.
2. After some time when I decide to unlock the bootloader again, would the unlocking go over the Mi Global Community or China Mi Community (Level 5)

The device is CN device.

Do you know or can you address me to someone who knows, thx in advance.
 
1. If you install EEA, Global, IN, TU, RU, TW on a Chinese device you cannot/must not try to lock the bootloader. The result would be cihla.png
2. If you lock the bootloader, you will again need a paid service or Chinese Mi account level 5 to unlock it again.

If you have a CN version of the device, the best choice for you is to install the xiaomi.eu ROM.

Hello Friend, im new here, i use an external service to unlock and install an eu rom updated via fastboot to the latest version, my question is, is it possible to go back to the original chinese rom?
 
- Installing in Miflash is a different process than installing xiaomi.eu ROM.
- Installation requires the use of the script clean all - flash_all.bat (Reset the entire phone including the storage!) or clean all and lock - flash_all_lock.bat (Reset the entire phone including the storage and lock the Bootloader).

Thank you, and yes i use that same tool but i have only updated the rom that an external supplier installed and unlocked my bootloader, but i wasnt sure that it was the same procedure.

I really love hyperos themes (chinese market), and some chinese apps, so it has been hard for me to pick the good one.
 
OK, you have the xiaomi.eu ROM. In that case you couldn't use Miflash to update as you claim.
Or I didn't understand what you wrote.

Two times have appear the updated window, and downloaded the two files in the picture, when they put the eu rom it was 09 version, and now I'm on 12 using mi flash, this is what you said is not possible? Or it's not possible to go back to Chinese version?

I say:
- It is not possible to install xiaomi.eu ROM using Miflash.
- You can install stock ROM using Miflash

Then i don't really know what happen, I was seeing the process that ncunlock did on my phone, and he uses mi flash, and I have been using miflash to update my phone.
