Exclamation [Help] Unrooting Samsung Galaxy S3 urgent!

About a month ago I rooted my Galaxy S3 and tried to install CM11. Long story short it did not all work out well because Knox security would not let me install any root apps. And the rumor is that the Galaxy S3 is about to receive the new KitKat update and I would like to unroot the phone before the update arrives so that I can have a chance to install it. 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.

Download the stock firmware, flash it with Odin, reboot to stock recovery and factory reset

I guess u can update your device when the update comes u don't need to unroot.... The update will automatically unroot your phone....
If I am mistaken pls correct me thanks.....

DONATE TO ME
The best bet is to get that firmware to flash. You can try using an unroot option if all else fails (in the supersu app, just choose Full Unroot).

But if you want to try to get the firmware flashed, we need more info about what's happening. In particular, what model device, your current firmware version, the version you are trying to flash, where you got it from, and most importantly, what does Odin say when it fails? (Copy the text in your post)

Okay, I'll get the text off Odin as soon as my phone charges to 80% or so. Should be about an hour or so.

Okay so now for some reason Odin won't add the phone when its plugged in and in download mode. Maybe its because my battery charge wasn't at 80% or higher? Or could it be because I deleted the SuperSU file? And was it a bad idea to delet the file? Kinda frustrated cause I have no idea what's going on and why it won't unroot, I just want my phone back to normal...

Did you open Odin after you plugged it in?

Of course I did. I'm going to try again later today. Hopefully it works.
