wiped os with twrp! please help!

[AC Question]

After rooting my note 4 i installed TWRP. after a few weeks my phones battery overheated and needed a day or two before it started to charge. until one day it went in a boot loop. Not knowing what to do next wanted to do a factory reset but deleted the OS. i tried reinstalling the stock software with ODIN 3, but when the file is installing, it fails. I also noticed that on my phones download screen it says reactivation lock: off. I'm at a loss, if any one can guide me in the right direction it would be greatly appritiated.
