Uploading firmware to ESP8266

Describe the bug
I’m trying to flash the nodemcuv2-ir onto the ESP8266, but it stop after initializing. The LED flashes (erase flash), but after that nothing happens.

To Reproduce

The COM port driver is installed. I uploaded some code with the Arduino IDE to the ESP8266 and that works without any problem.
So I think it’s not the device or some driver.

Expected behavior
Upload firmware

I now managed to do it with NodeMCU-PyFlasher . But I had to change the flash mode to DOUT . On the website you can’t choose the flash mode, so maybe the site uses DIO ? I couldn’t find the scirpt that’s running.
