How do I update kernel 3.3.7 to 4.7.9?

[winger9]

Thanks philo (#2). Could you tell me why I can't update to kernel 4.7.9?

Also, is there a kernel version that I can update to, which doesn't have the
bug which prevents the operation of my usb drive?

I've thought of another possibility, but I don't really know what I'm talking
about. Is it possible to do either of the following, in order to get the Seagate
drive to work:

a) Patch my present kernel (3.3.7).

b) Load a module that DOES correctly operate usb hard disc drives. I understand
that the "uas" module contains bugs that prevent correct operation of such
drives.
