Are you trying to flash back to stock? As in like you got the phone out of the box? Or are you trying just trying to flash a stock ROM? There's a big difference between the two.
Flashing a ROM is done via a custom recovery, not Odin ....
Yes Yank is correct if you have a custom recovery DON'T use odin any longer unless to revert back to stock....now before we had a custom rom beasntown did have a rom(kinda) that we could odin on our Verizon phones but since Adam(xda) cracked the bootloader we have custom recoveries
I, like the previous responders, question whether using Odin is the best solution for your problem. My questions are: 1) What variant of the Galaxy Note 2 do you have? 2) Is your phone unlocked? 3) Is your phone rooted? 4) Do you have a custom recovery? 5) If you have a custom recovery, did you make a backup prior to changing your phone? 6) Exactly how did you modify your phone?
