Use Odin to reflash a firmware of your country... after this your boot screen should change, and you may root again.
But you don't need to worry, because Win is the same model as Grand Quattro (it depends of country, in my homeland it's Galaxy Win) and your phone will work properly
I downloaded all type of drivers and also got original samsung usb but odin does not detects my phone can anyone help on this it is important drivers get installed proprely i tried all versions of odin too plz help gyuz
