EC200A-EU firmware update error


I need to use qmi mode so the command AT+QCFG=“usbnet”,2 returns ERROR.
So I tried to update the firmware of EC200A-EU modem but received an error message "User Customized ErrorCode"on QFlash v6.5.

Model of the module: EC200AEUAB-D10-UNASA
Current firmware : EC200AEUABR02A04M2G_OCPU_01.200.01.200
Target firmware:

Can someone help me?

I don’t think QMI is supported by this module.
You can check what is available with AT+QCFG=?

Yes you are right.

+QCFG: “usbnet”,(1,3,4)
