Orbi RBR50 Pulsing White and no Network Appearing

A week ago my Orbi mesh network completely went down (an RBR50 with 2 RBS50 satellites). The RBR50 was pulsing white and the network could not be found in any of my devices. I believe the satellietes...

Can you access the RBRs web page with a wire connected PC pointed to 192.168.1.1 after the reset button press of 15 seconds then release? 

 

If TFTP didn't work, then try the other recovery you linked. If that fails, then your RBR needs to be replaced.

    No, I've tried accessing the the web page at 192.168.1.1 via ethernet many times throughout the process and never been able to reach it. Will try connecting to the serial port and see what I can do.

        Connecting to the serial ports at least gave me a bit more information about the problem. It looks like there's something corrupted about the OpenWrt image because it runs into an error verifying the checksum:

        Is there a way to reinstall OpenWrt? I'm assuming the standard TFTP firware updates don't update OpenWrt but correct me if I'm wrong. Using TFTP to upload a new firmware version doesn't change this error message.
