    The only issue with the stable was updater crash when check for updates.

    Yes, im on miui 9.
    Miui 8 is known for its high battery consumption. My sot is 3 - 4h. I do not play games. Only surf via chrome, instagram, calls, messages, few pictures and about 30 min gps.
    Try miui 9, you will not make a mistake.

    I've got MIUI 8. Bootloader is locked (as table says about my version of MIUI). But I can enter in TWRP Recovery. Is it mean I can refresh my version of MIUI up to MIUI 9 without unlock bootloader again?

    @Inc-Arti: Bootloader gets locked by changing Android base from 5.x to 7.x, because there is a new bootloader file included in the ROM (emmc_appsboot.mbn). This happened with weekly 7.2.9 (see the instructions in this thread). So if you are on a version before - yes, your BL will be locked again. But you can easily unlock it again with official Mi Unlock Tool.

    No, you can't. You need to unlock your BL and a new TWRP compatible with Android 7. Look in thread 7.2.9.

    I already had twrp-3.1.1-1-libra with ROM 8. I didn't expect your reply soon and reflashed ROM 9 without unlock BL. I got a boot loop.
    Then I rebooted my cell phone into fastboot and unlock it via Mi Unlock. I rebooted my cell phone to system again. It's OK.
    I've got ROM 9 now!

    Hey guys, I would like to try this ROM. At the moment, my settings are:
    - Xiaomi MI4C rooted / bootloader unlock
    - recovery: TWRP 3.0.2.0
    - ROM MIUI-France 6.12.22 / Android version 5.1.1 LMY47V


    Do I need to update twrp to twrp-3.1.1-1-libra before I flash the ROM?

    Flash the ROM...then fastboot the recovery ...

    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

    I was on V8.5.1.0 Stable EU ROM. Bootloader was locked so i had to unlock it from http://en.miui.com/unlock/

    Next I used these guides below to install adb on my computer and install TWRP:
    http://www.stechguide.com/how-to-install-adb-and-fastboot-on-windows/
    http://www.stechguide.com/root-and-install-twrp-recovery-on-xiaomi-mi4c/
    https://www.youtube.com/watch?v=mgU9o4VN_GE

    TWRP:
    https://dl.twrp.me/libra/twrp-3.1.1-1-libra.img.html

    ROM (V9.1.2.0):
    https://androidfilehost.com/?fid=673791459329062515

    I uploaded the latest EU ROM into the phone before installing the TWRP.

    Once I installed TWRP, i installed the ROM, clear cache&dalvik, reboot phone.

    Hope this helps! :)

    Thanks for your reply. Before I start anything, I would like more details because I'm a newbie :)
    Just to be sure, I understand what I am doing.

    - Why do I need to install "MIUI 6.12.22"? I already have this version (not xiaomi.eu) and I could not find it on androidfilehost.com
    - Ignore the first point and let's assume that my mi4c is running with the 6.12.22 (xiaomi.eu ROM)
    Once I have downloaded TWRP 3.1.1.1 - Do I just need to reboot the device into fastboot mode and flash the .img to install the new TWRP?
    - Once TWRP is installed, do I install the ROM via TWRP or via another way?

    Thank your for your time.

    Hello,
    I have currently Miui 8.5.1.0 NXKCNED.

    To move to this 9.1 version, do I just have to put the zip on the phone and update,
    or do I have first to wipe something, and what ?

    1st you need to copy the ROM to your device
    ROM (V9.1.2.0):
    https://androidfilehost.com/?fid=673791459329062515
    Then you need to fastboot TWRP ...
    TWRP:
    https://dl.twrp.me/libra/twrp-3.1.1-1-libra.img.html...
    When fastboot of TWRP is complete use..... the command ...fastboot boot twrp.img. ...to boot to TWRP...Then while in TWRP install the ROM...wipe dalvik and cache ...boot to System
