Redmi Note 12S (codename: Sea) - how to install firmware from different region

[lukecz]

I have Redmi Note 12S from EU distribution
I would like to install a ROM from another region to be able to record calls.
Probably a Taiwanese rom offers this (there is no Indonesian rom for this phone).

I know that I have to use the fastboot method if I want to flash a ROM from another region.
I already have the bootloader unlocked and the MIUI 14.0.5.0.THZTWXM ROM (fastboot) downloaded

Can I find instructions somewhere on how to safely flash (fastboot) a ROM from another region to my phone?

Current MIUI version:
MIUI Global 14.0.4
14.0.4.0(THZEUXM)
Android 13 TP1A.220624.014

In attachment there is a screenshoot with extracted files - should I connect my phone in Fasboot mode and start flash_all.bat?

I guess after all this time, you already figured out by yourself.

In case you didn't: yes, just connect the phone in fastboot mode, install fastboot driver and execute "flash_all.bat".

Some people like to use MI flash tool, which is essentially a graphical interface that also executes the batch files in background.

PS: Never execute "flash_all_lock.bat"!! This would brick your device in most cases.
