[FIX] Samsung J7 Custom Binary blocked by FRP Lock

Hi guys, since I tend to do a lot of rooting stuff this was the first time it EVER happened to me. Same thing happened to Samsung S6 Users as far as googled, here's a link: http://forum.xda-developers.com/tmob...-help-t3146069
So basically if u get locked out of ur phone then don't panic (I did lol) :fingers-crossed: and Just flash the Stock Firmware using Odin. :) Peace out
P.S. I don't know how but my customized stock ROM's still standing lol no wipe or factory reset. I'm just happy to turn on my home screen again :D

supersu binary update failed on 5.0 device.

I've seen one or two threads that were in the same vein as this, but no clear resolution. Every time I open SuperSU, I get the message, "The SU binary needs to be updated. Continue?" I select "Continue," and am given the message to install it normally or through TWRP/CWM. If I try through TWRP, the phone restarts into TWRP, but does nothing. If I select "Normal," I get the "Installation failed!" message. I tried uninstalling/reinstalling SuperSU, but that didn't do anything.
I'm using 5.0 walton device.
