Wio field tester does not work

I live in Japan.
When I bought Wio field tester, I made a mistake in the setup procedure and set up this program after I set it up with AS923.

Work performed (STEP1~5)

As a result, only the blue LED blinked and no screen was displayed.
I then followed this procedure, and while the screen is displayed, I am not sure if the software is properly installed.

(Install Firmware on the WioTerminal)

I am taking measurements near the Helium Gateway, but it is not detecting LoRaWAN. (GPS is displayed).
I seek resolution of the problem.
