Sonoff Bridge Direct Hack not displaying AP for configuration

Please give any hint why I don’t have the AP after flashing with ready-to-go-binaries. I tried (erasing before) with Option 1 and 2 and the result is the same: the gateway doesn’t present the WiFi AP for configuration.
I checked and it is not connected to any existing WiFi networks.
Must be mentioned that it was working in the past but for a period of time I didn’t use this gateway.
Thank you
