iPhone SE locked and unable to unlock I forgot the pass code of my iPhone SE.
I have switched it off now.
Yesterday, I reset my pass code but now I can't remember it.
For iOS 8 and later, the only way to unlock the code is restoring from iTunes. Hope you already backed up your phone.

One more trick, ask your family member to see whether they knew the code. I once luckily got it back from my wife.
