All good suggestions, Parker, and that is the current FW for the device.
My light ring was spinning as I walked by it last week, I "panicked" and pulled the plug. I realized afterward that was not the thing to do right away, because I also knew the evening before it still did not have the latest firmware, so I plugged the thing back in. Lights spun for a minute or less, and then Echo said hello. I realized it was previously rebooting from the FW update, and when the light ring settled down I checked the FW and it had changed to be the current. I was relieved that I had only unplugged it during the reboot, and not the actual FW updating.
Perhaps the OP turned his Echo off during the actual updating, so it could take longer than "a while" for the Echo to get back to checking for the update again . . . maybe.
