ESP32 BLE after booting no Wifi available

Hi,

I flashed with the Arduino IDE my ESP32 with the V0.9.5. The first time I see the ESP Wifi and try to add the Configuration with my smartphone. But it failed (I think wrong Wifi Password).
Then I flashed it again with compiled Wifi credentials. This doesn’t work.

And when I try to flash the orginal Code now I don’t see the ESP32 Wifi and in my Route the Gateway also not connected.

At last I try to flash the ESP with the flash_download_tool_v3.8.5. But at Erase I get the Error “5-chip efuse check fail”.

One more Information: I need to presse the boot button the whole flash time is this correct? Otherwise I get an Error.

What’s going wrong? If you need more Information for help please ask.

Sorry for my English it is not so well.
