FYI - Had a lot of difficulty getting the firmware upgrade installed. Once I selected a Wi-Fi network that did not have special characters in the name (as per this YouTube video - https://m.youtube.com/watch?v=Amq4x2UuR_o) I was finally successful. Seems ridiculous that any Wi-Fi network name will not work. Don’t most of them have special characters? I was just lucky to have one without.
