As for the Knox problem, just flash the DE-SAMSUNGNIZER_KNOX_REMOVAL_SCRIPT_V1.0.zip I posted earlier to remove Knox

Good Luck!

The inability to downgrade didn't become an issue until 4.3. So if you were on anything older when you last did so, it would've worked fine.

That makes so much sense. Cause when I was in 4.1.2 I downgraded to 4.0.1 easily with no trouble. Thanks for the tips. I'm waiting on the new download as we speak!

Okay. Downloaded the correct firmware this time. And Odin recognized my phone. All good so far. But now its just been here for the last 10 minutes. Should I be worried or is this normal?

You should be able to restart odin at this point as it appears it hasn't started the flash. But if you want to be safe, just wait and after a while it'll fail and you can retry. Check your battery though!
If it shows any partition name in the top left box, don't touch it, but I think your safe as it hasn't said nand write start yet.

Make sure kies is uninstalled from your computer btw. It interferes with odin. Also, you can try both odin 3.07 and 3.09.

Wow, I am an idiot. I didn't press start! xD Such a noob. Sorry for bothering you. But so far it seems to be going well. Theres a green loading bar at the top where a word "SYSTEM" is. Almost done I think. I'll update you when its done. And lucky me, I am using Odin 3.09 xD

Wohoo! Doc! I think it worked! I stepped out of the room for a second and when I come back the phone is reset and turning back on. I then downloaded root checker and it verified that my phone does not have root! Thank you for all the help! You are a God send I may even attempt to root again now that I know not to try to flash older versions, cause its seems that was the big issue. Thanks again to all!

Any time! Glad I could help and happy to hear it seems to be back to normal!
If you do decide to root again, check out Towelroot. It doesnt get any easier than that!

I have tried on my own by following some instructions from some websites but so far nothing seems to work. I downloaded the correct firmware from SamMobile and downloaded Odin. When I plug the phone in and start the Odin process everything seems to be going well until a big red "FAIL!" pops up. I'm hoping I don't damage my phone in the process, but so far it hasnt been bricked yet. Please, any help is appreciated.
As far as i know when you root the device SuperSU should of disabled knox security.
