GT-I9000 2.3.6 XXJW4
Windows 8 64
Was unable until today to get it working, by any means (18.104.22.168 , 22.214.171.124...).
Just realized that using Kies 230.12035-16 and Windows (default) drivers (126.96.36.199.-16384) works ok !!
Installing Kies update version 252.13021-10 breaks it again... ("device model not supported")
Unable to load any other drivers than original Windows.
Will keep the old Kies version !
