after flashing NodeMCU is not recognize by Windows anymore

[Mrivilla]

Hi Dears,
I flashed my NodeMCU with the tool. I connected my NodeMCU to Windows and COM6 was recognized.
After flash the NodeMCU to appli the new firmware (by default), the NodeMCU is not working anymore, so Windows does not recognize the USB devise, so cannot be linked to COM6.

Any suggestion to flash or recover the NodeMCU?

Thanks.
Marcos.

I flashed an bin file and it works perfectly but my nodemcu is no longer detected by any computer(Even in flash mode).
