How to unBrick Linksys E8450

My Linksys E8450 is bricked. I'm not sure what I need to do and any help will be greatly appreciated.

I was loading OpenWRT and flashed the wrong package. Now there are no lights on or flashing and no ethernet connection.

I connected a serial cable with screen and tried to load files, but I'm not sure what it needs next. I'll attach a picture of the screen output.
