Question

The unit including modem was working.

I did a firmware upgrade which failed.

I recovered using Fastboot.

I have tried multiple firmware versions since with no luck getting the modem to work.

There is no firmware version for the modem in system.

I'll be connecting to an Australian carrier.

Is there firmware or a process to get the modem working?

Hello,

Thank you for contacting.

Can you specify how are you diagnosing that if the modem is not working ?

Could you share some more information about the issue you are facing ?

Have you already tried the following recovery options ?

Could you try re-flashing the firmware on the device without keeping settings?
