Stock TouchWiz ROM PLEASE HELP!

[AlfBriggs]

I flashed CM12 on my Note 4 and I've tried to flash a stock rom back but I keep getting a fail on Odin.

Save your effort just go to best buy and have Samsung rep flash it back to life... Did the same with a Note 3 and after several hrs did just that.... Was in and out in 30mins.

I am in the same boat as the OP.
The reps will really do that ? And not be mad about it?
This may be a stupid question but - The note 4 I have is Tmobile but was unlocked. Reverting back to the Touchwiz ROM won't undo the unlock, will it?
