For people who have the same problem, our target today is to fix “this iPhone is in security lockout null” so that we can get back to using our iPhone normally once again.

Part 1: What Does You Can Try Your Passcode Again in Null Mean

The first thing we are going to do is to explain to you what “You can try passcode again in null” means. When you enter the wrong screen lock passcode enough times, the iPhone becomes unavailable or goes into security lockout.

Usually, your iPhone will let you have the chance to try again after a period of time, and there will also be the Erase iPhone option. But if you enter the wrong password too many times, even a dozen times, when you tap on the Erase iPhone, the next screen will prompt you with the iPhone security lockout null message.

In this case, you can no longer try entering the lock screen passcode and the iPhone is permanently disabled. The only way to use it again is to reset it, which means losing all your data.

  • Tap on the Erase iPhone option located at the bottom right corner of the screen to continue.
  • On the next screen, enter the password of your Apple ID. And it will start the erasing process automatically. Wait for it to finish.
