No wifi in mox A with MIMO module

It for sure doesn’t work. But to know if it’s totally broken, can somebody tell what it means when all LEDs blink once a second (including LEDs in ethernet socket) right after I have plugged in the power. Is it hardware fault? I tried to plug out all the modules I could, but this didn’t change. Couldn’t find any documentation to tell what this means. “Rapid blinking” means hardware fault, but not sure if 1 blink/s is fast enough.

So now it is totally dead, why, I don’t know, as there is no documentation to help. And not sure if I even want to send email to support to ask about it, as I most likely just get ignored months by them. But maybe I have to try it anyway. This has become so massive waste of money and my time already.

EDIT: Made new a thread for this, as my issue is now totally silent Mox, and not just failed SDIO WiFi. All LEDs blink once a second right after connecting the power
