[Q] Samsung SGH-1317 stuck on Odin Logo after unroot or Odin Mode

view story

http://forum.xda-developers.com – I probably didn't have any business doing what I did, but I rooted my SGH-1317 successfully and now want to sell it and bring it back to factory fully wiped. I loaded the ODIN Mobile Pro app and followed the instructions that were the same on 3 sites to unroot and flash the stock ROM I loaded on the phone. It did everything properly but then the blue ODIN logo came on and nothing happened after that. I was plugged into the computer during this , so wasn't certain if this did something. NOW when I do the volume down button+ home+button and power button I get the Odin Mode that says downloading (HowTos)
