The boot log includes the phrase DRAM initialization failed!
- which sounds pretty terminal
There's other failures as well, however they seem to match "fails" in the OEM Bootlog
Note: this was running OpenWRT 19.07.8
Also, no lights (brief flicker on power up)
here is the boot log

It's served me well for a few years - I'd hate to have to throw it out (despite the bad rap it gets for its wi-fi issues)
