RF100 Settings after reinstalling firmware I have an RF100 v.1 printer with stock software (again) onboard.

After my attempt of changing firmware, the X-axis motor decided to stray printhead away out of the borders of the printer and somehow motor wires broke out of the adapter. 
I fixed the wires and reverted to stock firmware, though now whenever I auto-home or press "Home" button on Ultimaker Cura, printhead goes wild top and left reaching borders and starts buzzing like crazy.

current condition:


Head is TOP LEFT with X=100 and Y=100 on the table being under head Z=0;

Even with these beautiful tiny settings, I cannot print anything because printhead goes too far TOP RIGHT by itself.
Ideas?
Everything was fixed by thorough googling and flipping the whole wire-set of the motor. It started to twirl in a right direction.
Sorry for the time
