Ok, so I basiclly tried everything. I find the phone as Qualcomm blablabla in Device Manager.
I can flash the phone using MiFlashBeta.
The phone is not recognized by MiSuitChina or English. Yes I am booted in the signature driver thing mode on my computer
I cannot discover the phone in ADB session.
So I can flash it, but it seems to be stuck in EDL mode for some reason. (Phone totally black, nothing work.)
Im about to give up on Xiaomi
