Rachio Gen 3 - 1st LED flashing white then red - bootup error

I have a Gen 3 Rachio 16 zone that suddenly dropped off my network. When I went to troubleshoot it, it rebooted and now I’m stuck on a 1st quadrant flashing white LED with a periodic red LED.

This is a replacement unit. We did have a power outage yesterday, but it seemed to have no issues.
