Have you tried to revert the firmware to see if those settings start working again?

    Hi DarranM,

    Thank you for feedback and info.

    I test it with the old firmware downgrade to V1.0.0.52 and same Error message while downgrade:

    LTE MODEM UPGRADE FAILED

    After reboot same situation: Adjusting for "Mobile Broadnad Settings" are grey and connot adusted.
