I’m in the exact same boat. OEM software was running, then installed ROOTer/GoldenOrb. Was having issues and tried to revert back to OEM. Router seems to go into U-Boot mode (globe led is lit after five flashes of WiFi led when holding reset button during start up). But can’t connect through the browser (http://192.168.1.1)
Haven’t tried updating U-boot but it sounds like doing that didn’t work for you either.

Any progress?
