Yes, you received a notification. You can update using the fastboot method via PC.

This only applies to CN accounts and unlocking CN devices.
If you get unlock permission in Mi Community with a Global account, you can only unlock Global devices. Not CN devices.
If you are not a citizen/resident of mainland China with a CN account level 5, you cannot unlock a CN device.
If you get permission to unlock the bootloader (it doesn't matter what device was used for permission) you can unlock 3 Global devices within one year.
If you have a CN device you will not install network_fix.
CN devices do not support some bands, for example B20 (800MHz). This may be the cause of your problems.
Repeat the ROM installation/update and then install the fix for Android 15.

- xiaomi.eu does not contain/use root.
- installing xiaomi.eu ROM only requires an unlocked bootloader
- on xiaomi.eu ROM there may be a problem with specific applications that require strong integrity (they will not work). The reason is the unlocked bootloader.
1, the forum rule says "use English"
2, you're trolling me (TWRP doesn't see the device's storage, so you have to put the file you want to install via TWRP on some media and connect it to the device via OTG).
