Ok thats good you can enter download mode thats mean your phone is still alive

Now try this steps 1 hold down power key ,menu key and volume up key all together at same time until you enter recovery , in recovery do factory reset if it is stock recovery if it is custom press advanced wipe and check all boxes so you do full wipe with sistem ,chache, data ,dalvik chache and internal .

When you done factory reset pull battery out , put back in and flash again stock firmware + pit file in (ODIN 3.10 ) <-----USE ODIN VERSION ...and check repartition when using pit file for your device.
