Yesterday, I successfully flashed the firmware using the official tool and was able to connect to the internet as well.
However, when I booted it up today, the surrounding LED lights no longer had a breathing effect and instead, the power LED and the LED lights alternated blinking. I also couldn’t connect to the internet.
I tried reflashing the firmware but it did not improve the issue.
Are there any experts who know the reason for this? If I can’t find the cause soon, I may have to replace the board.
