Don't fret. One disabled vet to another, but my hat is off to you, sir. You were there before me, you crawled the trenches before I sailed the seas. Nonetheless, we're all here to help.
Firstly, if you followed the steps from the first post, you placed update.zip on the root of your sd card before you started the whole process of using Odin. Even if you didn't, no worries, because we don't use it with what's being done with Odin. It's only used when doing that CWM thing that I don't even do unless I have to.
That said, if you can get your phone to the big yellow triangle, hope is not lost.
Before getting back to there, I'd reboot your PC, get Odin back up and running, and reflash starting with this version
MEGAUPLOAD - The leading online storage and file delivery service, which will wipe the data from your phone. If that doesn't work, several of us have a few other things up our collective sleeves.
When you're done flashing, you should be up and running. I expect to be awake for a couple few hours tonight, so keep this thread running with your progress. I'd even consider calling you if you have a lot of issues and as long as my 1 year old is still sound asleep.
There can be many reasons as to why the flash doesn't work, like anti malware and anti virus scanners not being disabled when they should be, bad driver installation, my ex wife being the proximity of anything electronic, etc.
