I assume you have seen this documentation on his website? - https://www.leviathanautomation.com/manual
This manual looks like was updated in Feb and looks like it covers everything, he even has software image -
Yes, as I said I've read through all of their documentation many times, very thoroughly. It only provides instructions for using their pre-built image, which is non-functional. I've tried with half a dozen Pi boards, SD cards and power supplies (all known working) and it always fails at the same spot.
