When I visit About --> Software Information --> Baseband version

it says, G960WVLS3ARJ6 and I also noticed it says R16NW.G960WVLS3ARJ6 for the Build Number.

I'm following this tutorial posted at, [ Login above or register to see download links. ]

I am not sure why, but I chose to download the file named, G960WVLU1ARBG_G960WOYV1ARBG_BWA.zip from sammobile and that is the file that I'm using right now to attempt to downgrade. Today I've decided to download the earliest available firmware out of all of them to see if that one will work as well but my internet speed is slow so I won't be able to test it until tonight when it finishes downloading. So, using the firmware that I downloaded, I specified all of the proper files in Odin, the BL file with the file that starts with BL in the filename and so on. The only thing that I'm not sure about is that there are two files with CSC in the name, I chose to specify the first file which is the one without the word HOME in the filename because I did not want to retain any user data(got this idea from a forum post).

When I first started with this tutorial my Odin would always fail at the "connecting.." part but now that I've switched USB ports, It goes a little farther but still fails with an error message. I am using Odin version 3.13.1 and I followed the tutorial to the end. The only thing I'm not specifying in Odin is the one called USERDATA. My Odin Fails and gets stuck with the following FAIL message.

"<ID:0/003> FAIL! (Auth)"
