Need Help with the Fathom One ROV SD card

I desperately need the .img for my Fathom One ROV’s SD card. I either corrupted it, or physically damaged it. I have been struggling to fix this guy. I had a failed topside AP caused by poor assembly/manufacturing of the tether. Like some wires not even soldered…

So I had been powering it up and down multiple times as I tested it, not realizing that’s how you cook a Pi. And not a tasty baked pi either.

There are two Github repositories for files. Fathom Drone Archive and Fathom Drone App Looking through them I don’t see anything useful for this, but then I don’t know enough about Raspbian to know what would be useful…
