Think I screwed up big time...

I'm trying to send my Galaxy Note 2 in for warranty. It had accepted 4.3 OTA but I had rooted it afterward. So I went to restore to stock and unroot so I could send it in. I had just recently done another Note 2 (My dads) back to stock without a hitch so I figured it would be no big deal. Except I forgot one minor detail that his phone didn't take 4.3 OTA and still had unlocked bootloader. So I opened up Odin 3.07 and put PIT file in PIT and VRAMC3 firmware in PDA and hit start and the flash failed. Took me a few seconds to realize that I flashed the wrong firmware and should've been VRUEMJ9. I was panicing and downloaded VRUEMJ9 and attempted to flash that and it wouldn't even start the flash just failed right away. Now ODIN isn't even recognizing the phone anymore. Am I totally screwed here? I've been googling furiously and it sounds like maybe cause I selected a .PIT file it may have hard bricked my device? I just instinctively did that because it was required to make it work correctly on the last phone I did just a few weeks ago.

I can still access download mode but ODIN doesn't show anything in COM window. Trying to boot phone normally shows "Firmware upgrade encountered an issue. Please use Software Repair Assistant & try again" I've tried repeatedly restarting phone and rebooting PC and reinstalling USB drivers.

Any help GREATLY appreciated. I really really really don't have the money to pay full price for this bricked phone :(
