Need help installing 12864 lcd on Cr-10s PRO. (no replies)

Hi trying to post a post here.

I have a Cr-10s PRO. Fantastic machine but lousy firmware and display at the moment.

Seeing more have switched to Marlin 1.1.9 and using 12864 display similar to Cr-10s.

Want it to behave like TH3D's firmware.
Which firmware should I use and how do I proceed?

This thing i have control over:
Stock abl sensor.
Solder together r64
Solder together r66
The right layout for exp1 and exp2
