Firmware for LTE-M IoT Kit

Hi there. I am trying to get started with using the LTE-M IoT Communications kit with a Raspberry Pi. I followed the tutorial for setting up, but the dashboard still reads “Cellular Connection Unavailable.” I also noticed that the firmware version is listed as “Unknown.” Is it necessary for me to install new firmware on the modem before I can use the kit? If so, I have seen in previous posts that attempting to had resulted in the kit no longer being operational. Is there a warranty or other actions I can take if this occurs?

Vendor: Telit
Name: ME910C1-WW
Firmware: Unknown

I have exactly the same problem. Only with the WLAN the connection works.
