for 4.4.5 i modified here, then initially the router couldnt detect the modem even after one reboot
i switched to another usb modem that uses tethering then switch back to the external modem it then able to establish data connection (and set ttl works)
how long it can stay online, will monitor
update modem not so stable in this firmware, it goes offline randomly and becomes undetected by mt3000, maybe theres more configuration required but its out of my capability
