I've been trying to root my Gs4 the past few days. I have tried 3 different versions of Odin. and I get the same error on all of them. I have also tried 3 different types of the root file you use with Odin.
I have verizon
The error in odin is:
<ID:0/004> Initialzation..
<ID:0/004> Get PIT for mapping..
<ID:0/004> Firmware update start..
<ID:0/004> boot.img
<ID:0/004> NAND Write Start!!
<ID:0/004> FAIL! (Auth)

And the phone says:
