Try to flash the miui rom again.
And then, flash twrp and patched vbmeta again too.
Just avoid the file "misc.bin" and everything will be okay.

I think the most important acronym in the firmware. EU. Flashing the RKBEUXM should therefore not be a problem. Even without the bootloader unlock. OR only means that provider-specific functions are built in. If you don't know them or are unimportant, the XM works just as well.

If you had to unlock the bootloader to flash the XM, I wouldn't relock again. That would surely lead to a brick.

Hello! Can you tell me what method you used to do it? I have a Mi 11 lite 5G, the ROM that came from the factory was a Vodafone EU and I changed it for a Global EU ROM, specifically this one: renoir_eea_global_images_V12.0.8.0.RKIEUXM, but in the process with My Flash Tool the bootloader had to be open, now I have this ROM working perfectly, but I want to close the bootloader to use Google Pay etc. So I am very interested in your method to achieve it.

Don't relock your bootloader with EU rom. Your chinese phone will be bricked.

Need help for downgrading

I am on MIUI 12.5.1.0.RJOINXM. My bootloader is locked. I don't have prior experience in flashing roms. Please help me to downgrade to MIUI 12.0.8. Thank you
No way. You must unlock bootloader then flash the older version with official Mi flash tool.
You can downgrade to any version using spflashtool easily, securely and safely.

Oh, okay.
If you flash in DOWNLOAD MODE, bootloader will keeps SAME, locked or unlocked.
If you flash in FIRMWARE UPGRADE MODE, bootloader will be LOCKED again.
If you flash in FORMAT ALL MODE, bootloader will be LOCKED again and you will lose all identications of the device like IMEI, BLUETOOTH MAC, WIFI MAC.
You can downgrade MIUI safely and securely using download mode.
Thank you, but what is DOWNLOAD MODE?

Dear VD171, i've just downgraded using MiFlashToolV2. The process was simple and the bootloader is still unlocked, so far so good.
But now it refuses to boot to system. It keeps restarting and shows the initial "Redmi", with the unlocked icon in the top.
I tried to Wipe data in xiamoi recovery, but the result is the same.
Please advice

Could you express your problem in a little more detail? Like what recovery mode? And why do you need to wipe data? What errors do you get?
- Kenora
first important things: your phone is full stock? i suppose you have installed magisk with some modules. try entering in fastboot mode and ser your current active slot. switch to other slot and try reboot. but if u have a data backup, best solution is a full clean flash of full stock firmware via miflash or other tools
edit:u can also try reflash stock boot.img and vbeta.img with dmverity check disabled. seems a boot.img problem
Hello, friend, I have the same problem as you, and it is completely compatible with your mobile phone hardware model, the same is M2103K19C Maybe the Global version model is different, so it cannot be updated, but not necessarily, the solution, do not update, Wait for the next version and try again, MIUI will launch MIUI13 update

Normally yes, anyway the bootloader is unlocked and in case of problem you can use Miflash to recover the phone.
EEA have restrictions, notably maximum sound volume.
