LTE qmi crashes the squirrel with OWRT 19.07(latest update)

[triviad0r]

Hi,
 

I have been extensively exploring the PS for the last month. During that time I managed to make the PS work with a LTE usb dongle , providing a serial 3g/umts connection successfully.
Everything worked like a charm until I got into situation where I needed stronger signal and decided to move from "serial" to "qmi" protocol (the dongle is DWM-222 A2 and supports it). However, when I try to add the the WWAN VID&PID to the qmi_wwan file it crashes the PS. 

I am placing the usbmode command and json that I initiate to change the mode of the DWM-222 as well as adding the VID&PID to the qmi_wwan file, after which the squirrel crashes.
Will appreciate if anybody has any suggestion on possible ways to overcome this problem.
