Can anyone help me do the DLC weapon glitch and i have the tutorial right here

Add AK_Scorpion_75

Pretty simple. for the one helping, they need to
1.)Host a public match party lobby (where it says create a class and not arena or custom game)
2.)kick the one doing the glitch when they join.

For the one getting the DLC weapon(s)
1.)Turn off internet on ps4
2.)go into Black Ops 3
3.)go to multiplayer
4.) load 2nd controller
5.)start game
6.) while counting down before the match loads, turn on internet
7.)when match starts, dont spawn in, go to the friend that is helping and join them with 1st controller
8.) while loading spam x until back in multiplayer on local
9.)load 2nd controller again
10.)with 2nd controller go to create a class and then hover over kn-44
11.)join friend with 1st controller (you should get a ui error i think)
12.)have friend kick when you when you join
13.) go back into public match with 1st controller
14.)2nd controller press left dpad
15.)go into create a class with 1st controller and hover over any weapon that hasent been bought with unlock token and hover over unlock(works best with equipment, but secondaries work better)
16.)press o with 2nd controller and hover over dlc weapon
17.)press unlock with 1st controller then hit x and unlock and equip and when it asks to confirm it should be a white picture for the weapon.
DONE!
