1. Sign into the ps4 with the higher level account you want to dupe.
2. Go to multiplayer then click public match.
3. Now I sit there for about 30 seconds.
4. Press Circle to get back to where the guy with the two guns is at (Main Menu)
5. Hold down the ps button then go down to switch users, Switch to the low level account or the one you want to dupe over.
6. As soon as you're logged into the lower level account tap (X) once then wait a second then tap (X) again.
7. From here you should be on local, head to play online.
8. Find game and join. Get a kill or death then leave.

The glitch should now have worked and you duped an account with one controller.
*If the level doesnt stick lag your connection. I use hulu or netflix seems how my internet is already crappy. These are the steps I have been using, occasionally my black ops 3 will force close then you will have to retry it. I found this completely by accident. I just decided to post it today because everyone else is. I was going to initially release it when the 2 controller method got patched. Thanks guys have a great day / night. Im willing to help anyone out that needs help with this.

Nice tutorial.. Now the big question is..... Does the leaderboards work with this glitch?

I know it's an idiotic question, but anyone been perma-banned by this or 3Arc have only been resetting levels???

ok cool, and also just as a follow up question; would you think I would fly under the radar of the 3Arc reset wave if I do a prestige 7 account going from a prestige 3 legit? I don't really want level 1000, just to go through a couple of prestiges. also, what level did you copy from if I may ask? Thanks in advance
