Net config fail after update

I’ve got a somewhat odd problem with my SA30. I just updated it to the latest build (host v1.72, net v2057, ARC v1.7, ARC Rx 1.0.0) via USB, and now when I try to configure it to the wireless network, Google Home connects to the device without trouble, but when it tries to connect to the network, it fails.

What’s interesting is that I’ve tried all the usual drills.

  • Ensure device has been removed from Google Home
  • FAT32 USB stick, freshly formatted, containing only the new image.swu
  • Power off, disconnected all speaker wires, inserted USB stick
  • Held down service reset button, power on, waited 60s before releasing
  • Update flow went through normally, ending in “Update Completed”
  • Net reset
  • System reset
  • Power off, reconnect speakers, power on, go into NET input
  • Open Google Home, attempt to add new device
  • Connects to device and tones play through the speakers
  • Attempt to connect to wifi network (and verified SSID and password)… and nothing happens until it times out.

My WiFi router shows no attempt to connect to it, and the SA30 itself persistently shows no SSID, IP 0.0.0.0.

I’ve tried a few extra net resets, and repeating the procedure from scratch (down to reformatting the USB stick and downloading a fresh image.swu) a few times, and the same thing happens each time.

What’s frustrating is that before this upgrade, it was basically working – except that it kept trying to download and install the latest firmware every time I powered on, and would end with “Update Failed.”

Does anyone know what this might be?
