Unlocked Bootloader is not really the root.no root?
without root i can´t install stable rom, or not?
i have installed magisk, twrp. can i install the EUModule.apk also?
For switching ROMs (like Xiaomi.eu to stock or vice versa) you need the unlocked Bootloader
But once you successfully flash stock ROM, re-lock your BL (otherwise, although on stock ROM, Play Integrity will fail) and after that you no more need Xiaomi.eu injector - and once you return to stock, this Forum is no more for you
