    Is the above guide correct? I read nothing for Mi-unlock tool or for how to apply for the unlock (and get permissions then try unlock with the official tool for this, etc).
    Flashing a multi-language rom with Mi Flash does not unlock the bootloader, it just flashes a rom over the one on the phone. TWRP will need the unlocked bootloader however and will not boot with a locked one.
    Please clarify and correct the post soon (as someone may try it and get boot-loops).

    PS: I have Xiaomi redmi note 3 PRO with unlocked bootloader so i know how to do it!

      How did you unlock the 3 Pro?

        The phone when I received it had the official Chinese Rom. To unlock I “upgraded” (using the updater system app) to developer Rom (to unlock you must be on dev Rom) then used the mi unlock tool (need a pc and a mi account that has applied for the unlock and has received the approval sms) and tried the unlock (success at first try) After that I used a simple bat file (along with recovery file) from a miui.com admin to pass twrp recovery (through adm) and from there on everything was “piece of cake”.Actually i am writing this post from my redmi note 3 pro with a custom Greek community Rom (the ones from Xiaomi do not have Greek).

    After running successfully the abovementioned manual I wanted to install Cyanogenmod. Howevern, when trying to install the latest Cyanogenmod (snapshot) through TWRP is encounter the error message the version could not be installed as the device is a H815… The build.prop the device name is ‘aqua’ and not ‘h815’ so I do not understand. Someone?

    UPDATE: removing the device check [1] does not solve issue as other error messages about the file system occur. I’ll check with Cyanogen whether the Mi4s is actually supported…

    Hi guys and girls,

    Today I bought New MI4S,

    And since i got it with Chinese ROM i tried to unlock bootloader and did
    every step correctly via this tutorial (
    https://www.gizchina.com/2016/03/28/unlock-xiaomi-mi4s-bootloader-install-multiple-languages/
    ) after the
    The operation completed successfully!

    in MI flash message i disconected my phone and tried to power it up. And
    got nothing. I scrolled down to see that if u get bricked device try
    the steps again.

    Again, the process has been done with no errors, but the phone is not responding.

    After that i tried to flash fastboot rom, also with The operation completed successfully! message and still, the phone is dead.

    I have read this topic > http://en.miui.com/thread-277775-1-1.html.

    But i have few Q if i have the same situation and solution as our colleague.

    Simptoms:

    Screen : Black

    MI logo : No

    Vibration : No

    LED/indicator light : No

    Fastboot : No

    Mi flash : Yes, PC sees MI4S and i can flash but without resault.

    Charging indicator : No

    MI PC Suit : does not detect him.

    I have seen that i need to let him discarge and then try to restart him?

    None of key kombination works.

    But how do i do it, since i do not know how much battery is there left ?

    Any advice before my wife kills me?

    How dead am I?

    Thx guys / girls for any support.
