I take absolutely no credit for this.
After jacking up my vibrant... I needed to flash back to "out of the box" status. After hunting around a bit I came across this and SUCCESSFULLY flashed my phone back.
I'm passing this on for the people who are new to flashing with this particular phone and don't know where to start etc.

A couple of things I noticed while flashing mine.
First... getting to download mode was giving me crap at first. Then i found this tip on page 21 @ post 206:
This worked for me.
Also, after getting everything setup right and working.... I noticed that Odin didn't seem to be doing anything... to which I found this reply on page 20 @ post 198:
This also worked for me. My phone didn't flash until the second time around. I also restarted my pc and made sure to be using the files provided in the first post for good measure. (Odin, the .tar & pit)
As for the "NAN" backup.... I'm not that advanced yet and don't pretend to know anything about it. Hopefully this will help other people who have messed up get back on track.
Mods, not sure if this is the correct or best section for this... but I figured if the phone is that messed up... it's probably due to actually messing around with the root files etc and deserves to be here in this sub forum.
