[GUIDE] How to install Xiaomi.eu ROM for Xiaomi 12/12S series


I did everything,

meanwhile I found all the settings required:

1. Developer Mode ON
2. OEM unlocking
3. USB Debugging
4. Mi Unlock Status
5. Login, logoff - in MI account dozens of times

All good, but still can´t connect to the phone.
a. Fastboot ON
b. MI Unlock Tool started
c. Signing in MI acoount

Still no connection to phone possible "Not connected to the phone".

I give up. A sad waste of time and money.
 
Do you have the necessary drivers installed on your PC?
- install USB drivers & adb and fastboot tools
- install xiaomi drivers (sometimes necessary)
-> a small [howto] if you have driver issues

Did you sign in to the MI account via Data (not WiFi) on your phone?

Did you restart your phone?
It is not a problem for you. It is nothing that would prevent the normal use of the phone.

Best regards
 
Hello. I got the same problem yesterday with my new 12s.
I had to flash the original Chinese ROM again in order to make the phone get to live again.

Is there any guide on how to install new recovery ROM for mi 12s ultra?

I've tried to follow this https://xiaomi.eu/community/threads/howto-install-recovery-image.66211/

But it fails, it says
Code: 
Sending 'boot.img' (102400 KB)                     OKAY [  2.180s]
Booting                                            FAILED (remote: 'Failed to load/authenticate boot image: Bad Buffer Size')

I got stuck on fastboot mode and had to install the previous fastboot image back 13.0.8

Which twrp did you downloaded? It seems your twrp file is broken…

Info from @NODO-GT
Do not download form this link, this twrp is not working (https://androidfilehost.com/?w=files&flid=329796)
get it from here: https://dl.akr-developers.com/?dir=skkk/TWRP/A12/v6.2_A12

# FAILED (remote: 'Failed to load/authenticate boot image: Bad Buffer Size')

Hello,

I am seeing this error when trying to run mac_fastboot_first_install_with_data_format.sh (same error when running with windows script on PC) on my Mi 12S Ultra:

This package is for "thor" devices; this is a "unknown".

Device is unlocked and in fastboot.
 
Hi how are things?. Yesterday I installed TWRP for my Xiaomi 12 (Cupid) and everything is ok, it works perfect. But when I wanted to install the new stable rom xiaomi.eu_multi_XM12_V13.0.39.0.SLCCNXM_v13-12.zip I couldn't, everything was fine, but in the end it gave an error. I have the xiaomi.eu_multi_XM12_V13.0.36.0.SLCCNXM_v13-12-fastboot.zip. I tried it by OTA and normal from the TWRP and nothing, from 36 it does not happen.... Is it possible that I have to install 37 first and then move on to the new one?, I can't think of anything else. Does it happen to anyone else?, Thanks to all
 
I installed TWRP and everyhing ok but when i tried to install last xiaomi.eu it doesn't boot the rom and boots again to the twrp. Where is my mistake ?

I had the same problem. We need to Format Data first, not Factory Reset then install the ROM.
 
Hello, I have a Xiaomi 12 and in the phone settings it tells me that I must update it. So when I download the update from the computer and unzip the file, the .bat files do not appear anywhere, instead, everything appears completely different. I attach a screenshot of the unzipped folder to see if you can help me, thanks.
