Hello, I just bought a MI6 with a chinese ROM. I'd like to install a XIAOMI.EU ROM on it that suports French. Could someone explain me the detailed procedure to follow? Presently it's running MIUI 220.127.116.11 beta, and an update is available (MIUI 18.104.22.168 weekly) but I didn't launch it. Should I downgrade to an older MIUI version? For the moment I just created a MI account... And which stable ROM would you recommend to maximize battery autonomy? Thank you for helping me!
