Upgrade issue from iOS 8.4 Beta Update to iOS 8.4 GA
For those having issues with upgrading from the iOS 8.4 Beta to iOS 8.4 GA. Below resolved my upgrade issues.
Updater was stuck on requesting update, and did nothing for about 2-3 hours. Was having a tough time with the beta profile installed on iPhone and iPad removed it from both. And attempted update again and it worked like a champ.
Goto "Settings -> General -> Profiles"
Delete "iOS Beat Software Profile"
Reboot "Home & Power"
Attempt iOS update after device is done rebooting.
If you want to re-enroll into the beta program for iPhone or/and iPad. Navigate to "beta.apple.com/profile" this will reinstall the beta profile.
iPhone 6, iOS 8.4, 128GB
