Have you tried reverting to "as delivered" software!

I’ve tried everything. I found a bin on creality’s website but it makes the extruder motor run backwards. The filament moves away from extruder head!!

Your printer cannot finish homing procedure.

This procedure require correct orientation of stepper motors and endstop logic.


Stepper motor direction per axis you can check from LCD.
If the stepper (/s) direction is reversed you need to either recompile Marlin firmware with changes or simply change motor cable pins order in the connector ( 1-2-3-4 -> 4-3-2-1 ).

If the endstop logic is wrong easiest way is to connect printer to a computer and access terminal (from software such as pronterface or Cura's monitor).

Then write into terminal command "M119" and it will show their current status:
- if not engaged endstop status should be "OPEN",
- when engaged status should be "TRIGGERED".

If you encounter problems with endstops check any faulty wires to be sure.
