how do you view passcode history for iPhone 4s?

If you could find out a passcode that easily it wouldn't be worth much. If you've forgotten yours:

IPhone, iPad, iPod touch: Wrong passcode results in red disabled screen

Please Get the iPhone User Manual for iOS 5

However, iPad Mini 2 IOS9.2 that is my device, I have a question close to yours.

I have tried several way how to check log for un-passcode or power on.

But I can`t find out nice solution so far.

I did below.

1) Install IOS CONSOLE for MAC.

2) Connect Device to Mac.

3) Turn on IOS CONSOLE.

4) You can see your any log but it is current one not for older.

5) Another way to check log is you can click clash log on IOS CONSOLE.

6) Now you can see inside your Device. Maybe there is such a log on here.

7) I am searching....... If someone know it, please tell me!

8) XCODE seems helpful. But it is close to 5GB. I will try it on this weekend.

Thanks!
