What image do I need?

I messed up my Opnsense install and need to re-do it. The problem is the location the system is in does not have a display nearby. I brought up my spare TV and found out that it is broken. 

The system I am using has four Ethernet Ports labeled 0 through 3

Port 0 is going to Internet Connection 1
Port 1 is going to Internet Connection 2
Port 2 is intentionally unused right now
Port 3 is going to my network

I temporarily replaced my Opnsense system wigth an RT-AC68U so I could get the internet back up because my wife needs it to work tomorrow

Only way I can think without a physical screen is to use a network connection i.e. ssh
Then you could try after seeing if you can figure out what the problem is, to save a config file from it to a safe location and then proceed to re-bootsratp it.
