If you download the driver package to your PC host it creates directory “Linux_for_Tegra/nv_tegra/”. Within that is file “nvidia_drivers.tbz2”. You can extract just the one file and copy it over to the Jetson, or you can just place the whole “nvidia_drivers.tbz2” in the “/” directory of the Jetson and unpack it:
# On the Jetson...assumes nvidia_drivers.tbz2 is there...
cd /
sudo tar xvfj ./nvidia_drivers.tbz2
Perhaps verify both before and after with this (if the file shows as correct before then there is no need to do this…if the file was incorrect before unpacking then it should be correct once again after unpacking):
sha1sum -c /etc/nv_tegra_release
