You all know the importance of SHSH blobs. However, for those of you who still do not know, I will tell you several details. SHSH blobs stands for signature blobs sent by Apple whenever an iOS user wants to downgrade to a previous iOS firmware. In order to do this thing, you need to receive confirmation from the Apple server and this confirmation is available only for a short time. Because of this, users have the possibility to save SHSH blobs in order to have access to a future downgrade. There are several cases when users upgrade accidentally their firmwares and they encounter hard times because it takes some time until jailbreak is available. In order to help them, developers released the iFaith tweak that gives you the possibility to save SHSH blobs. Basically, iFaith creates a separated file into your computer, which contains SHSH blobs from your iDevice. This file will help you to downgrade your firmware to a previous version each time you want when Apple no longer signs for confirmation. Users are also able to view all previous saved SHSH blobs on their devices.
Here is the list of supported devices for iFaith 1.4.2:
-iPod Touch 4G/3G/2G
-Apple TV 2
Here is how you can save your SHSH blobs by using iFaith for Windows only.
-After you download and install iFaith 1.4.2. On your computer, launch the application.
-Next, you need to follow all steps suggested by the program whenever a new window appears.
- Put your device in a DFU mode by using the iTunes support and retrieve the SHSH blobs.
- When you are asked to, you need to find a location to save your currently SHSH blobs on the main screen of your computer. Preferably, you may choose the old destination that used to contain saved SHSH blobs.
-Finally, after the process is done, disconnect your device.
Now, you have saved SHSH blobs for your device and you can downgrade anytime you want. Therefore, if you use iFaith 1.4.2 you need to know that it offers support only for Windows, which means that Mac users will need to find something else to save SHSH blobs.
