Thanks! So for my raspberry pi, I had to run the lite-qmi-nasarm binary for it to work (not nasrpi). Also, for it to connect to internet again (and LED to flash properly), I have to re-plug the usb adapter for the modem.
BTW, when I try to clear the cell locking list by pressing enter key in option “41”, It says SetCellConfig errorCode: 1090 - Incompatible State. How can I clear the list?
