EG915U problem burning QuecPython fw

I have EG915 revision EG915UEUABR02A04M08 (EG915U-TE-A_V1.2 mounted on a on UMTS&LTE EVB_2.2 and I want to flash it with a QuecPython firmware QPY_OCPU_V0001_EG915U_EUAB_FW
So, from QuecPython i downloaded: driver, tools (for Window10) and the firmware: QPY_OCPU_V0001_EG915U_EUAB_FW.

Following the video “Download firmware” “ 烧录固件_QPYcom_0317.mp4” I tried to flash this firmware, on the module, but it doesn’t seem to work.

I opened QPYcom V2.9 selected download tab, then project QuecPython, and selected the firmware, then click on Download FW ….

After that I pressed “Dowlonad FW”, windows lost the modem com port, and seems that the modem is turned off.

What can I check?

Thank you and best regards,
