Hi, in this case, the firmware upgrade did not complete successfully. Please try moving the hub closer to your Wi-Fi router, and then retry the firmware upgrade.
If you have not already done so, we also recommend separating your 2.4 GHz and 5 GHz Wi-Fi networks and connecting your smart home devices to the 2.4 GHz network. This may help provide a more stable connection.
Thank you for your time!
