Support for Nexxt Nebula AC1200 | Model: ARN04904U2

Hi guys. So I bought a Serial-to-USB-TTL cable, hooked it up to this router's 4 pin serial, successfully got a serial boot log here: -- I also successfully extracted the firmware for this router and have access to the filesystem. I have a telnet connection to the router where I can run all sorts of commands.

I ultimately want to install OpenWrt. What other info can I gather that the boot log doesn't provide? It seems very similar to a Tenda AC9

old thread, although same boat for an nyx1200-ac. how far did you get?
