You can't just flash kitkat roms directly from stock recovery,, you need a custom recovery to do that,,, here is the work around :
1 first reflash stock rom again
2 secondly flash a custom recovery from odin ,,, use luigi way of one step recovery and root
3 after that when you are able to boot into custom recovery,make sure you have cwm recovery >6.0.4.5 installed otherwise you will not be able to flash kitkat roms. For the record, you can flash phillz recovery 6.19.6 from custom recovery.
When you are done,please come here again
