My Cloud Home hard drive replacement

Hey guys,

I’ve recently bought previously used 2TB My Cloud Home but without hard drive. Bought myself WD Red 3TB (absolutely compatible) to put it in and I tried to make a factory reset but it seems like it’s totally bricked and it doesn’t respond to me pressing reset button. What are my options from here? Do I need any kind of virgin image to mount? I’ve searched for answers for so long and basically found nothing useful here and there.
