Is there a way to either (1) install v8.82 on the watch to downgrade (to a version before my watch started completely failing to connect to a phone), or (2) to completely flash the firmware on the watch to a known good state?
I see from https://www8.garmin.com/support/download_details.jsp?id=14933 that 9.56 is available, and that also includes a way to downgrade to 9.00 after upgrading to the beta. I went ahead and upgraded to 9.56, but I'm getting the same error when trying to pair the watch to any phone (I've tried pairing with 3 devices). I suspect that downgrading to v8.82 might fix my issues, but I don't know where to get the 8.82 .GCD file.
Alternatively, is there a way to completely re-install the firmware on a watch from a computer?
