MC7455 mmcli modem status Disable

I’m using the MC7455 in Canada (already tried different telcos).
The Linux Modem Manager shows the device status as “Disabled”, and Power as “Low”.
AT CREG and CGREG both returning 1,6.
Does anyone have a clue why this is happening?

Further investigation, it seems that there is a mismatch on firmware:

 preferred fw version:
 preferred carrier name:  GENERIC
 preferred config name:   GENERIC_002.017_000
 preferred subpri index:  000
 current fw version:
 current carrier name:    GENERIC
 current config name:     GENERIC_002.017_000
 current subpri index:    000

 fw version mismatch


you need to upgrade the FW:

Thanks for the info.
Do you know any tutorial I can use to flash the module with the new firmware?
The module is connected to a Linux embedded system with Ubuntu on it.

You need to use fwdwl in MBPL SDK and driver

You can download the MBPL here:
