Unable to unlock bootloader

[Marcb]

Hi everyone

Before creating this thread, I have searched a lot both in XDA and the Xiaomi official forum and I wasn't able to find an answer for my issue...
The thing is, I've purchased a Mi Note 3, China version and it came with the GLOBAL ROM and a Locked bootloader so the chinese store that I've bought from must have installed that in some unofficial way.
Now I want to unlock the bootloader... I already bounded my Mi account to the device, enabled OEM unlock in Developer area, but in Mi Unlock Tool I keep receaving the message at 50% that the device is already unlocked, which is not the case.
I'm not sure what to do... I already updated to the latest GLOBAL ROM 9.5.3.0 but still I can't seem to unlock it....
Also, when I enter FASTBOOT mode and try to "fastboot device-info" to check the status, the CMD Prompt doesn't respond... it seems the command is not received to the phone, only "fastboot devices" work...
Fastboot drivers seem to be ok... I'm using Windows 10 x64 1803 update.

I have no idea what the chinese did to this phone... but the ROM is original, as it updated itself to the latest version...

I was able to pin point the problem... apparently Xiaomi drivers and apps don't like Ryzen and AMD chipset very much... I've tried the same thing in my laptop (Intel) and it worked... same Windows 10 x64....
That's very weird... I'm not sure if it's something related to drivers.... anyways, now it's unlocked!

Thanks!
