Orbi RBS50v2 Satellite Pulsing White Continuously

Just an update in case it helps...

When powering on the satellite, the LED on the back by the power button is constant green (not flashing green) for a few seconds, then flashes red continuously.

Have tried a different power supply, just in case that was causing the issue - no luck.

Also, when trying the nmrpflash utility to try to update the firmware, have tried it on two Windows computers, so two different LAN connections. The utility just isn't communicating with the RBS50v2 satellite, making me think it is dead.
