Best thing to do is flash stock rom via odin and start again - this will wipe the phone and restore stock firmware

You will need
odin
your phones firmware
usb cable
samsung usb drivers
a windows pc

Best search your device specific xda forum for firmware and how to's or you can get firmware via the sammobile website

Can't I flash a zip file...
How to flash firmware ... Through Odin can you elaborate
Which file is needed for that... I know how to flash recovery but not firmware

like I said - look at your phone device specific forum for how to's

you can google how to use odin but the instructions are on the first link given with odin itself in the post attachment

Hey buddy I am not able to flash through Odin can you please help..
every time I get struck on initialising or setup connection..: messgage

Either

1 - you have not put your phone into download mode and pressed vol up to start connection
2 - you have not installed the samsung usb drivers

if everything in odin is working you will see com:number in a coloured box under com:id on the left hand side of odin when your device is connected
