The system has been destroyed

[reptkeu]

I was trying to flash a new ROM onto my Redmi K50 Pro. I couldn't see the device in ADB when in Fastboot.
I stumbled upon some ADB command: ADB OEM UNLOCK, and it bricked it.
It now shows the message "The system has been destroyed".

Still not able to see the device in ADB, so I can't flash a ROM.
I was able to see the device in ADB when I was in the OS.
I think it may have to do with MTP not setting the propper USB protcol, which prevents me from seeing the device and flashing it.

Any tips?

And when I try to flash, I get the following:
"ERROR: could not clear input pipe; result e0005000, ignoring...
ERROR: could not clear output pipe; result e0005000, ignoring...."

I assume it's because the phone is simply no detected.

Any suggestion on how to address the issue above?
