Why did you tried to unlock bootloader on damaged phone? 

 

 

n.. the pc doesn't recognize it.. keeps telling me that drivers needs to be installed..

What device shows up in device manager?

so I can flash a stock rom (

unkown device

You don't need to unlock bootloader to flash the phone. That was a stupide move. Try to hard reset your device, read user guide how to do that.

tried everything from this site: hardreset info

I cant do method 1 'cause I cant even turn on the phone

method 2 just keeps loading and

for method 3 I cant enter flashmode

Any tips?

Xperia C4 is not supported and probably will never be. Describe your problem in a new thread in Sony Xperia C4 forum.
