Apple Court Ordered To Help FBI Unlock an iPhone Passcode. Is It Even Possible? Unlimited Passcode Attempts Bug on new version for iOS 9.2.1.
This will only works for passcode not for touch id screen lock.
This happen because of screen glitch let you hold the display and trick the many bugs ios have. only works when the iphone is one minute disable. but after that you will have more 28 minuts until the ios remove all data until this time you can do all combination you want unlimited times.
