Mi 8 Bricked from nowhere

Hi,
I have a big problem and i don't really know where to ask help so i'm trying here.

So , my Mi 8 is stucked in EDL mode, I don't know how, I just woke up with my mi 8 on EDL
I tried some thing like boot in fastboot and recovery ( both didn't worked ) so I tried to re-flash by EDL and there's my problem.

When I try to flash using Miflash , the flash seem to start and then I have the message "ping target via firehose"and than "write time out, maybe device was disconnected"

I was on xiaomi.eu rom, my BL is unlocked, I tried different USB ports, USB cables, computers, multiple ROM and multiple Miflash versions, I even tried the pinpoint method.

I'm starting to think that the problem is the emmc who seems to be damaged :/

Can someone help me please ?
