Zoom Ring Calibration - Distance and locked

[Eirikstrand1996]

Hello, I just bought a 5D mark II and a Sigma 24-70 F2.8 and i had an issue with the autofocus switching on and off manual/auto. I opened up the lens and was able to fix the connection issue, but I managed to mess up the focus for distance. Does anyone know how to calibrate it or a guide / article / YT / name?

Am not sure that will work since the ring is stuck and if i loosen the screws it will only go from 1m - infinite. So no focus under 1m
