I’ve a TRB140 4G modem for which I didn’t update FW for a while because for some reason the FOTA is disabled and when I try to enable it from the web interface it says: Failed to edit configuration.
So I’ve downloaded the latest FW, which is TRB1_R_00.07.19.4_WEBUI.bin at this time. I want to keep configuration settings (keep settings ticked), but is this safe for an upgrade from version 07.07.1 to 07.19.4 ?
