First, how'd you get to this point. Was this associated with rooting / flashing / something else? When you get into download mode, are you trying to Odin something in? It shouldn't say "Firmware upgrade encountered..." unless you're trying to push something. What happens when you get into recovery mode?
Second, do you know which factory image you started with? That's important, because if you started with an earlier image and flash an newer one, you can't go back. and the earlier the image, the easier the root.
This thread has no-wipe factory images. They're large files, so heads up.
You need Odin working. Good luck.

And if I don't hit any buttons, it just said "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again".
I just want to be able to use my phone again, I'm totally alright with having to wipe every bit of data off of it and have it absolutely factory new. How can I do this? I could use Odin or Kies. However, Kies can't recognize my phone and just says "Device not responding. To resolve the issue, reboot the device." I'm tried dozens of times, it just can't find my device.
Please help.. I am phoneless and I could care less about losing data at this point.

If you don't know what build it has, I'd start with flashing a no-wipe MK2 image.
I'd start with a MDK, earlier doesn't hurt, and I believe that's the first factory image released officially
and here's a full wipe image for MDK (erroneously called MKD in the title)
I'd try the No-Wipe images first
