Bluetooth: где получить intel/ibt-12-16.sfi встроенное микропрограммное обеспечение для Ubuntu 14.04? (Йога Thinkpad X1 Gen2)

Признак (переключатель Bluetooth может только быть установлен на прочь) и сообщение об ошибке, которое я получил, являются почти тем же как в этом вопросе, но я работаю 14.04, 64 бита. Действительно ли возможно, что я получаю это встроенное микропрограммное обеспечение для 14,04?Спасибо!

Править: Как предложено в ответе, я попробовал

cd /lib/firmware/intel
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/intel/ibt-12-16.sfi

и перезагрузка. Bluetooth теперь обнаруживается, но он все еще не может обнаружить мою гарнитуру. Вот то, что я получаю:
