    Hi guys, I recently replaced the battery of my phone and I also want to upgrade my firware since I have been having problems with internet connection lately.
    My current version is:

    Android 5.1.1 LMY47V
    MIUI: 7.1 by xiaomi.eu stable 7.1.4.0
    Twrp 2.8.7.0

    Can you please suggest a stable rom without bugs? I was pretty happy with the one I have now, but I still want to upgrade it.
    I have read that with the upgrade to Android 7+ the camera has lost sharpness, did they fix that with new versions? Can you please help me with the upgrade, providing a detailed guide? Last time I have played (installing custom roms I mean) with android was 2016 when I bought the xiaomi. Thank you for your help.

    Your BOOTLOADER will be relocked after upgrade from Android 5.1 to Android 7.0 MI4C, Mi4S, MINote PRO so unlock it by en.miui.com/unlock after ROM installation again!!!

    How to upgrade to Andoid 7.0:
    Install MIUI 6.12.22 before updating to Android 7.0..
    Select zip in Updater - menu - select zip
    Unlock your bootloader again on Mi4C, Mi4S, MiNotePRO
    (check your bootloader status by command "fastboot oem device-info")
    Install TWRP for 7.0 via fastboot "fastboot flash recovery twrp.img" "fastboot boot twrp.img"
    In case of issues, wipe /data in TWRP
    For ROOT use latest SuperSU
    Please read this thread completely...many options...problems and solutions ..

    Hi!!!

    Is there a possibility to upgrade the system?
    I'm currently on last China dev rom.
    I can not unlock bootloader, same meesage every time "Current account cannot unlock this device" for last two month.
    I tried with another Mi acount and got the same message.

    If someone knows how to solve this, i would be grateful.

    instala la versiĆ³n 6.1.7 que viene con el gestor de arranque desbloqueado, le haces rott , despues le metes twrp, y ya puedes instalar la rom eu que quieras y el gestor de arranque se quedara abierto, saludos ,
