NVidia Driver issues after SystemVersion swap.

[uiane]

I'm using El Capitan latest build of 10.11.6.
As usual when i'm about to install Pro Tools (last oficial supported version is 10.9.0) I change the SystemVersion file during the installation procedure and change it back Before restarting.

This time, after restart, the nVidia Drivers are now displaying that (Not Compatible) message in the system preferences.
And I'm stuck with Graphics acceleration and lower definition.

I've tried, uninstalling, rebooting, re-installing, rebooting, to no avail...
nvram -c (terminal)
rebuilding caches.

Anyone can help me ?
Thx!

Same situation here have you found a solution?

Also in the same situation, now with 10.13.2.

EDIT: Solution - reinstall latest OS update from apple. Redownload latest driver from Nvidia.
