Dimmer is completely unresponsive

I have a red series dimmer. I tried updating the firmware with Hubitat’s Device Firmware Updater. The switch is now completely unresponsive, both through Hubitat and at the physical switch. When I pull the air gap then push it back in the LED turns red, then green, then blue. After that I can’t get it to do anything. I tried holding the config button for 20 seconds to reset it but the light LED never comes on. I tried 3x the config button to exclude and that doesn’t work either.
Any thoughts?
