ESP32C3-M1 binary upload, no hotspot is showing up

Hi,
try to setup an ESP32C3-M1 with the following setup:
esp flash download tool V3.9.6
boot_app0.bin
bootloader_dio_80m.bin (also tried esp32c3-dev-m1-ble-bootloader.bin)
esp32c3-dev-m1-ble-firmware.bin
esp32c3-dev-m1-ble-partitions.bin

(erase… SYNC…press Boot-Buttom…FINISH)

cmd output:

Uploading stub…
Running stub…
Stub running…
Changing baud rate to 115200
Changed.
SPI_BOOT_CRYPT_CNT 0
SECURE_BOOT_EN False

after unplugging and plugging in the usb-plug, no new wifi shows up…

Did I miss something?
every kind of help appreciated…

thx
Manfred

update: not sure if i have to use USB or UART mode, but tested both…
