Here are some info:
LCD 12864 is from Anet A6 <--- might be the problem.
Marlin firmware - tried different version.
and yes, define motherboard to BOARD_MKS_13
and LCD to define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
flipped cables to lcd 180 - did not work, blue flash on board (D4) when i did this.
Now, if it is because of the Anet LCD, ill wait on another LCD 12864
