You should be able to do it all via USB cable and ADB, *if* you have USB debugging enabled *and* the PC has been approved on the phone. All that will require a functioning screen. But once those 3 things are set, the stock OS will flash from the PC using the script included with it. So download the factory OS from Google, extract it. Ensure ADB is available on the PC. Once the screen is working, enable USB debugging, connect to PC, approve PC, then use ADB on PC to send a reboot to recovery command (I think it's: adb reboot recovery). Once in recovery the flash script can be run on the PC. Edit: I've done this dozens of times - the flashing script simply overwrites the partitions with the factory software.
