phone crash after ios8.4 upgrade, frozen with connect to itunes logo
How to restart phone after IOS8.4 upgrade without losing media stored on the phone if I restore? Phone is frozen with connect to itunes logo on screen and I received error -39. I did not do backup before I installed the upgrade and I do not want to lose the photos stored on my phone. Everything I have researched online points to restore is my only option??
iPhone 6, iOS 8.4
