Well, after some more tries, the Arduino Create Agent finally software bricked my Arduino Uno R4 WiFi device. I am disappointed that by just using the software provided by Arduino I could lose my device that was working perfectly well before I thought to try the Arduino Cloud IOT. And then when I researched the matter, I find that it has happened to others. I am trying to recover the Uno R4 following steps in the below link, but I have failed so far.
I am disappointed.
