I think I bricked my SkyConnect. Many months ago I believe I flashed Yellow firmware to my SkyConnect perhaps at the wrong baud rate and it has been non-responsive since then.
Is there any hope of getting it up and running again?
I’ve tried flashing from the web, Home Assistant, and universal-silabs-flasher. It seems like no connection to the device can be established, but it does show up in my serial devices.
