Mobile Broadband cannot connect Ubuntu 16.04 with EM7455 Qualcomm Snapdragon X7 LTE-A Lenovo Thinkpad X260 notebook [duplicate]

У меня небольшая проблема с установкой модема в мой новый ноутбук Lenovo Thinkpad X260. Модель модема - Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A, а ОС - Ubuntu 16.04.

На экране входа в Ubuntu у меня появилось всплывающее окно для ввода PIN-кода, поэтому я отключил PIN-код для SIM-карты в мобильном телефоне. Это абсолютно свежая установка Ubuntu, загруженная и установленная в мае 2017 года с абсолютно ничего больше не установлено, только пытался запустить модем. На выходе получается

Mobile Broadband - не включен в Network Manager.

Я попробовал создать новое подключение в Настройки > Сеть > Мобильный широкополосный, но после создания его больше невозможно нажать на него, оно нигде не отображается. Когда я нажимаю диспетчер сетей, я могу создать новую сеть через Edit Connections, но опять же, это вновь созданное соединение нигде не отображается. Я также попробовал программу под названием Sakis3G, но безуспешно. Я не хочу переходить на Windows только из-за этого.

То, что я где-то нашел и попробовал:

1. Первое, что я сделал, это вставил sim-карту в мобильный телефон. Интернет там работает, и я отключил PIN-код на карте. Более того, я протестировал модем в Windows 7 и 10, и в обоих случаях он работает.

2. Я создал файл /etc/udev/rules.d/99-sierra.rules со следующим содержанием:

   ACTION!="add|change", GOTO="mbim_to_qmi_rules_end" 
   SUBSYSTEM!="usb|drivers", GOTO="mbim_to_qmi_rules_end" 
   
   # загрузить модуль qmi_wwan
   SUBSYSTEM=="usb", \
   ATTR{idVendor}=="1199", ATTR{idProduct}=="9079", \
   RUN+="/sbin/modprobe -b qmi_wwan"
   
   SUBSYSTEM=="usb", \
   ATTR{idVendor}=="1199", ATTR{idProduct}=="9079", \
   ATTR{bConfigurationValue}="1"
   
   # добавляем новый идентификатор в драйвер qmi_wwan
   SUBSYSTEM=="drivers", \
   ENV{DEVPATH}=="/bus/usb/drivers/qmi_wwan", \
   ATTR{new_id}="1199 9079"
   
   # загрузить модуль qcserial
   SUBSYSTEM=="usb", \
   ATTR{idVendor}=="1199", ATTR{idProduct}=="9079", \
   RUN+="/sbin/modprobe -b qcserial"
   
   # добавляем новый идентификатор в драйвер qcserial
   SUBSYSTEM=="drivers", \
   ENV{DEVPATH}=="/bus/usb-serial/drivers/qcserial", \
   ATTR{new_id}="1199 9079"
   
   LABEL="mbim_to_qmi_rules_end"
   

3. Я добавил внизу файла /etc/modules

   usbserial vendor=0x1199 product=0x9079
   

4. Я создал /etc/usb_modeswitch.d/1199:9079 с содержимым:

   DefaultVendor= 0x1199
   DefaultProduct=0x9079
   TargetVendor= 0x1199 
   TargetProduct= 0x9079
   CheckSuccess=20 
   MessageContent="55534243123456780000000000000606f5
   0402527000000000000000000000"
   

Вывод некоторых команд:
