Corrupt firmware

[Trickyricky]

Orbi Srs 60 wired backhaul  firmware V.7.2.0.122

when i turn the satellite on I get a flashing red light at the switch, which means i have corrupt firmware. I have tried the set to factory settings to no avail.

the unit is out of warranty.

What do I do??

thanking you in advance

Flashing red light at the switch? Not at the orbi? 

Did you try it with it disconnected from switch/router? 

You can try recovering it with tftp or nmrpflash.
are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.

and if that doesn't work, you can try using nmrpflash

I think "switch" means the power button on the back of the unit, right next to the LED.
