iPhone 6 iOS 8.0 stuck on certain passcode And not running more coses


I have an iPhone 6 iOS 8.0 and I ran the v7 test point and it will cycle through the numbers but then it gets stuck on a Certain passcode eg. 0715 and won’t go past this. The unit keeps rebooting and showing its trying the same passcode over and over again and the code is still code 2 showing everything is running properly

Anyone have this issue?
