I was having an issue with tagging system here in blogger. So I decided to have just separate the firmware for different phone. And it is much easier to to search my blog for the firmware.
You can use this firmware in Odin to flash or unbrick your phone. Use HJsplit to join the file.
For drivers you can download it here
Samsung Driver Pack
When flashing your phone make sure that you have enough battery juice when flashing your phone. This will make sure that you are safely flashing your phone. And also check your USB cable.
