I tried Windows upgrade FW with no problem. May I ask why the linux firmware application might get stuck in the download process?  
MBPL is the latest version of R25 on Sierra source

@jyijyi

The EM7565 has been specified with tty and cdc devices (-d and -p flags) and download mode set to 1 (-t 1 flags). But still stuck there

how about using the same command as this one?

> Thank you, that worked! For anyone that stumbles into this, the solution to load a firmware into the EM7411 is to make sure you specify BOTH the tty and cdc devices (the -d and -p flags), AND the download mode is set to 1 (the -t 1 flag). The final command is: fwdwl-litearm -d /dev/ttyUSB0 -p /dev/cdc-wdm0 -t 1 --modelfamily 4 --fwpath "./" --cwe SWI9X50C\_01.14.03.00.cwe --nvu SWI9X50C\_01.14.03.00\_TMO\_002.005\_000.nvu

I saw in the readme file of USB driver:

```auto
Enable zero length packet in usb_wwan
=====================================
To support FW download on 9x50 based products, driver must support USB
zero length packets (ZLP). This feature is not enabled in the open source usb_wwan driver
(for some kernel version). 
The attached usb_wwan.c shows how to enable ZLP.

In usb_wwan_setup_urb function, the following two lines of code:

	if (intfdata->use_zlp && dir == USB_DIR_OUT)
		urb->transfer_flags |= URB_ZERO_PACKET;

This indicates the ZLP feature is enabled.

```

You can double check your USB driver.

Confirm that in the usb\_wwan\_setup\_urb function, the following two lines of code:

if (intfdata-\>use\_zlp && dir == USB\_DIR\_OUT)  
urb-\>transfer\_flags |= URB\_ZERO\_PACKET;

@jyijyi  
I tried it and the result is the same as on the virtual machine.  
Can’t find where is the problem.

how about shutting down MBIM mode in AT!USBCOMP?  
Just leave the RMNET mode there and retry.

Tried just leaving the RMNET mode there, same result.
