There is no going back. Devices that have been installed with iOS 8 can no longer downgrade to iOS 7.1.2 since Apple already removed the option. The only way to solve issues with the new operating system, particularly the iOS 8.0.1 version, is to go where the tech firm leads, and that is to update to iOS 8.0.2.
The company says, "iOS 8.0.2 is available now. It fixes the loss of cellular service and use of Touch ID that may have affected you if you have an iPhone 6 or iPhone 6 Plus and you downloaded iOS 8.0.1. It includes improvements and bug fixes originally in iOS 8.0.1."
According to MacWorld, other issues that the update addresses include not being able to access photos in the Photo Library, not being able to use HealthKit apps, data usage when using receiving SMS, among others.
The easiest method is to solve the problem is to update wirelessly. Users, of course, need to remember to back up their data. If they want to be sure that they have enough storage space, they can tap Settings, General, and Usage. If there's enough space, then they have to plug in to a power source to prevent losing power while the update is taking place. They can then select Settings, General, Software Update, Download and Install, then Install. They have to type their passcode when asked.
Some individuals may find that the update is taking too long to download or install. Users must remember that download time depends on the connection speed, so Apple suggests being patient and simply allowing the device to update in the background. If, on the other hand, there is no progress after an extended period of time, then the user may have to restart their device.
If the handheld does not have enough storage space, then the user will have to connect to their computer and do the update via iTunes. To do this, they first need to have the latest version of iTunes installed in the machine. Then, they need to plug in the device via USB cord, select the device name in iTunes, click Check for Update, then Download and Update.
Surely, Apple is now working double time to fix any other issue that may still be present. It's just that many device owners got overexcited about the new operating system that they went ahead and installed it without giving it time to become stable (the first few weeks are always crucial, for it's when a lot of software bugs are discovered). It has been reported that about 40,000 iPhone 6 and iPhone 6 Plus units were affected, but there are no estimates as to how many users of older Apple devices downloaded the iOS 8 as soon as it was released. Unfortunately, the operating system is deeply flawed, as everyone concerned soon realized.
Apple has offered an apology, saying, "We apologize for inconveniencing you if you were affected by the bug in iOS 8.0.1."
