The essence of the method is simple! The method worked only on firmware 4.70-4.72
Activate the account in the game, then go to the Deactivate section, but do not click "Yes". We disconnect the LAN cable, we get the dns error. At the moment, ps4 is on defense, because the connection is disabled when deactivated.
On the account control panel, ps4 remains suspended on the account, but in games we get locks. Then again go to the deactivation section, click again to disable (yes, do not click).
We turn on the LAN cable, wait 5 seconds to connect to the Internet and click "Yes". As a result, the activation signal can be received in a couple of seconds - than PS4 sends a deactivation request when the "Yes" button is pressed.
In the control panel we receive a free account - we sent a deactivation signal. And games without locks - since we received a signal from the server that our account was activated on this subject.
What did MTX-key do? Nothing! They just burned the light bulb when we got a connection to the server, and only after that it was necessary to click the "Yes" button. This is an indicator that reacts to interference.
