How to Downgrade from iOS 7 to iOS 6 on iPhone 4

Just as it is with each new release of an iOS version, iPhone users are always looking for ways to go back to the previous version they’re much used to. Despite the UI overhaul that came with iOS 7, several people wish they could go back to iOS 6.x just because there’s no jailbreak available for iOS 7 yet. Though Planetbeing announced about a week ago all the pieces needed to jailbreak iOS 7 is available, pod2g later announced that a release date is still not in sight. Anyway, if you’re using an iPhone 4, you can still downgrade to iOS 6.1.3 or 6.1.2 using iFaith.

Please note that this tutorial will not work for iPhone 4s, iPhone 4, iPhone 5s, iPhone 5c or any iPad or iPod Touch running iOS 7. This is strictly for iPhone 4 and iPhone 4 only.

Before proceeding, please take note of the following :

• You need to save SHSH blobs already on your PC. There’s a post on how to do that here with TinyUmbrella
• This procedure won’t work without saved SHSH blobs
• iFaith is available for Windows only
• This is strictly for iPhone 4 only, it won’t work for any other iOS 7 supported device
• You may be unable to restore from an iOS 7 backup once you downgrade to 6.1.3 or 6.1.2
• You may have to restore from a previous iOS 6.x backup if this happens
• Nothing should go wrong but you’re doing this at your own risk

Follow the steps below carefully to downgrade from iOS 7 to iOS 6 using iFaith :

1. Download iFaith and unzip the file.

2. Download iOS 6.1.3 for iPhone 4 here.

3. If you have the latest iTunes version already, uninstall and install this :
