BCM70015 Firmware Download Failure

Hi, I’ve just re-installed OSMC on my ATV1 (2016.01-1-HDD). Install went smoothly but upon playing some h.264 videos, I’ve noticed they are not being decoded by my CHD card (dc:ff-h264 upon pressing o during playback). dmesg over ssh yields:

osmc@osmc:~$ dmesg | grep crystal

Any help or suggestions would be appreciated!
