After firmware update the NVR Resets continuously

This afternoon after continued harassment about updating the firmware to the latest version, I did just that. IT WAS A REALLY BAD IDEA!!!

The system was working well and I was really liking it, now I have a useless piece of tech.

Can the system be reverted to an earlier firmware or do I have to return it and get another…

WD, you have mostly good tech but this really disappoints me.
