Downloaed iOS 9 update, updated the phone, when it finished, it rebooted, and is now stuck at the lock screen, cant swipe up for option menu (wifi, brightness etc) or notification pull down. Also now when I try to unlock it to open the phone it shows I need to enter a 6 digit passcode... I have never set a passcode for this phone ever. Wont connect to itunes and shows that I have to unlock it with a pass code (that I never set to begin with) to use itunes. Wont boot into DFU mode either since itunes wont connect with it to restore from a backup. Any insight of what this thing is doing? I use my phone for work and business and CANNOT go without my phone for a day. Thanks!
