I tried following this tutorial to change mode of my Huwaei E3372 modem https://blog.unixweb.de/usb-stick-lte-telekom-magenta-eins-huawei-e398-modem-raspberry-pi/
System Raspberry 3B+ OS: Raspbian Stretch
But when i run:
usb_modeswitch -v 12d1 -p 14fe -M '5553424312345678000000000000001106200000010000000000000000000000'
