Have you done a nandroid backup? And also can you access to CWM? If yes try to erase everything.
And for odin do you used download mode? Try to unzip the stock rom and put it correctly in program then use download mode, connect your phone and let's start till it finish.
If everything don't work, go to S.A.V and say you don't know what happen'd to your if your warranty is safe.
