A week ago I rooted my phone and changed the firmware to an Android Google Play Edition 4.4 Kitkat. Now, I would like to return to the official stock version. I downloaded the firmware from sammobile and other sources. When I try to flash using Odin, always get a FAIL. This is the ODIN messages history.

I tried changing the USB port, uninstalling and instaling Kies, I used different root files, even I used a PIT file, following the steps in this thread (http://forum.xda-developers.com/show....php?t=1727443). I already check kies is not running on background. I tried with different Odin version (1.85, 3.04, 3.07 & 3.09)
I dont know how to fix this problem. Please if anyone can help me I really appreciate.
Thank you so much for all your replies.
