need to update my phone to new os kitkat coz it giving problems. plz help me with the link. let me knw the downloads required to be done and their links.
There is no such thing as a Kitkat installer that we can link you to. You need to know the exact model of your phone and the exact region your phone is allocated to and you need to get the Kitkat firmware for that exact model.
If the update for that model was not built, then there's no way to update that phone.
