International Business Times UK

Apple has stopped signing iOS 6.1.3 and iOS 6.1.4 for devices capable of running iOS 7 and users will no longer be able to downgrade their devices running on iOS 7. Besides, Apple has killed the ability to restore custom IPSW for iOS 7 with iTunes 11.1.

However, there is an exception for iPhone 4 users. Those who have saved SHSH blobs for iOS 6.1.3 will be able to downgrade their devices from iOS 7 to iOS 6.1.3 or earlier firmware version using iFaith.

4) As the process involves restoring the device with custom iOS firmware file, restoring it from backup will take some time.

6) Although the iOS 7 backup may not be useful once the iPhone is downgraded, it is always recommended that you create a backup using iTunes or iCloud so that users can recover data if something is lost during the downgrade process.

7) The iPhone 4 should have battery charge above 80%.
