I have an HA running on Yellow with a CM4… but could never get the Silicon Labs MGM210P Mighty Gecko Module to function for Zigbee nor Matter Over Thread (and could never successfully switch firmwares).
I figured I would just factory reset, but I’m ready to ram my head into a brick wall.
I’ve watched videos and tried these steps:
Created USB key using the Pi Imager
Confirmed my yellow jumper was on USB and not UART
Tried to factory hard reset (unplug PoE, replug PoE and press/hold red button for 10 seconds.
These steps never get be a functioning yellow HA status light and never get me to a place where i can factory reset. (come to think of it, I’ve NEVER seen the yellow LED work.)
The unit just loops and reboots and fires straight into HA.
What do I do? I just want to start over fresh. I got this unit from Seeed Studio exactly a year ago. I’ve had it running, but since I could never get the ZigBee nor the Matter Over Thread to function properly, it’s just been sitting. I want to love it, but if the basic step-by-steps of factory resetting doesn’t get things going, I’m going to go bonkers.
I’ve heard that you cannot run the reset using a USB 2.0 flash drive. Is that real?
Thanks for the guidance.
