Modem Manager unable to initialize Sierra 7455
Hello!
I have a Lenovo X1 with a preinstalled Sierra 7455 chipset, running Fedora 31. Gnome and ModemManager have done a great job detecting the hardware, and I get to unlock the Modem by entering the PIN and it registers with the network just fine.
However, whenever I try to connect with my carrier, I get a timeout.
I tried using qmi-firmware-update
to update the firmware on the card, but the software would wait for a few seconds before failing with an error that said that the device cannot be initialized.
Can somebody tell me what I'm missing?
I'm attaching journalctl
and mmcli
output
