Hello,
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: QPY_OCPU_V0006_EC200A_EUHA_FW-1.zip
Can someone help me?
