Thanks—that was a helpful answer.
I am still stuck on what artifact the “vanilla” OpenWRT compile should be deploying to the device without bricking it. I’m afraid if I install the wrong thing, it will brick my device again. So I’ve compiled according to the instructions, but what is the name of the binary artifact I pull out of the build directories and upload AFTER uploading s1300-factory-to-opemwrt.img ?
This is related to Bricked S1300 - #2 by alzhao where I haven’t gotten an answer there either.
