[Q] Rerooting Samsung I337
I apologize if my situation is here somewhere. I have read through so many forums and can't find what I need, plus I am sort of new at this. So here goes.
I rooted my Samsung I337 about 8 months ago for the first time. I can't remember exactly how, but I followed a thread here to do it. It worked perfectly! I then flashed the Golden Eye rom to it through TWRP. I have loved it since then. I did a back up of my original rom on my phone from the start. Well, I decided yesterday to unroot it. I followed the directions from a thread here and it seems to have worked except that when I turn it on, the custom screen is first. However, I have no supersu and when I try to get rooting apps it tells me I need to root my phone. So I assume it worked.
Well, I have used it for a day and now remember why I rooted it in the first place. I want to put it back but can't seem to do that. I downloaded Odin, connected my phone, and when I try and download the file to it, it fails. This is what I get.

The only thing I can see is that I am told the COM port should be yellow and mine is blue. Does that make a difference? What could the issue be? Any help would be awesome!
