[atlas] Failing probe, all lights blink

This is a new one for me. A V3 probe, when powered on, lights the power light, and then blinks all other lights for about a second every few seconds. Forever. I opened a case on it and was referred to the USB stick recovery process. Sigh. This is not that problem, I know how to deal with the USB stick issue. Has anyone seen this? Is there a deeper recovery trick we can use? I'm perfectly happy to attach a console to the TP-Link device. I was planning on doing it anyway to see what errors I am getting.
