Many iPhone 4 users with saved SHSH blobs designed for iOS 6.1.3 can downgrade iOS 7, 7.1 and 7.0.4 to 6.1.3 via an application known as iFaith. The tool is created and developed by iH8sn0w. Through the iFaith Tool, you can be able to downgrade your iOS 7 to iOS 6.1.3 on iPhone 4 platforms.
The compatibility of your device will depend on the type of SHSH blobs files previously installed. However, the iFaith tool designed by iH8sn0w does not work on such platforms which do not have SHSH blobs files including the iPhone 5 platforms and other iOS 4S devices.
Before downgrading using the app, it is important to remember toback up all your device data, ensure that your phone is fully charged and that you are connected to a working Wi-Fi network. Another key thing to remember is that iFaith app can only be accessed by users running on windows for computers. Users on Mac may not be able to install and use the app on their computers.
Before you begin using the iFaith tool, you need to search for the latest version of the app which is iFaith v1.5.9. This version of the app works well with iOS 6.1.3 firmwares which can be downloaded from Google. You can now go to your computer and launch the downloaded iFaith application. Upon installation, windows will give you four options including an option with the SHSH Caches available on the Server which you have to choose. You will then proceed to allow the iFaith app to configure your device by choosing the option displaying the SHSH blobs present on TSS servers on your PC running Windows. It is important to choose the right 6.1.3 SHSH blobs after which iFaith will be able to install the appropriate downgrade tools for your iDevice on Cydia.
The iREB r7 Jailbreak for iPhone is another important mostly used app designed by iH8sn0w. This is a Graphic User Interface application which helps in putting iOS platform tools into a jailbreakable form to allow users to install cracked apps which are outside the Apple store.

The iREB program is usually compatible with computers running on windows operating systems. In order to make the restoration of your device possible, you may need to create a custom firmware through many of the available programs like Sn0wbreeze and Redsn0w.
The iREBr7 tool works by making use of the iTunnel in order to upload three different jailbreak files enabling iTunes to accept the IPSW firmware of your iDevice. The jailbreaking tools uploaded usually correspond to a specific iOS device platform.
