    Please help! I am trying to flash the latest global stable or developer ROM to Mi4 with MIUI Global 7.2.4.0 (KXGCNCK) that I suspect is a modified ROM because of al the popup comercials and such.

    I tried using Mi Flash, downloaded the latest Global ROM (tried both Global and Developer). When I press Flash I get to 1s and it says succesful.

    Bootloader is locked, I don't know if that's the problem. It was bought that way.

    This device comes with an unlocked bootloader. Download a fastboot rom Miui V8 android 6.0. And he also tested with various versions of Miflash tools.

    I know Mi4 comes with unlocked bootloader. Had the same problem with diferent Mi4: after flashing fasboot global stable rom I was offered OTA update which locked the bootloader. Trust me, this one is locked. My question is: could the locked bootloader be the reason why I can't get past 1s flash successful when flashing eather official global stable or developer?

    There is no way to lock it. Are you sure you have Mi4? I replayed a screenshot from Settings - About the phone - Miui version.

    It's something they do with new ROM-s. Like I said, had the same problem before, someone instructed me to unlock it unofficialy via comand that went something like: fastboot oem device unlock. So I did and was able to flash twrp and xiaomi.eu weekly.

    I checked by: fastboot oem device-info. Bootloader is locked.

    But I had redmi 2 with locked bootloader recently that I succesfully flashed both global stable and developer ROM.

    But with this Mi4 it's done in 1 sec and says successful but no change is made to phone.

    I honestly do not believe the bootloader has locked you up. Download the recovery rom and through updater upgrade. You should call it update.

    "fastboot oem unlock" should unlock cancro bootloader.

    That is how I unlocked mine when I ended up with locked bootloder while trying out Global stable and wanted to revert to xiaomi.eu.

    But is locked bootloader the problem? Is locked bootloader relevant if flashing Official ROM-s?

    I will have to give trying different versions of Mi Flash a chance. I only used the latest available and that got me no where.

    Or is there a specific ROM I have to flash given that I'm upgradeing from android 4.4 to 6?

    Yes, you can't write on most partitions (except with MiFlash in download mode).

    Any official factory image from en.miui.com should work, i always flash latest china developer version if going to xiaomi.eu weekly.

    I am giving it another try, this time taking screenshots. Did the fastboot oem unlock command, bootloader now says unlocked, still no luck flashing global stable via fastboot method. What am I doing wrong?

    I think twrp and xiaomi.eu will work just fine on Mi4 LTE-CT. It`s a cancro device
    Minimal to no risk at all flashing twrp, if successful you can flash any cancro rom
