Download the 4 Odin files in this thread http://forum.xda-developers.com/show....php?t=2703006
(ignore the home file) and the PIT file. In this case you do want repartition checked in Odin...it will check it automatically when you load the PIT file just make sure to leave it checked.
This will wipe everything so backup what you want to save first.
Hope this works for you bro and it's not a hardware issue
