The iFaith was recently upgraded to the 1.5.6 version in order to support iOS 6.1.3. The new update allows users to save blobs on iOS 6.1.3 for their A4-based devices such as iPhone 4, iPhone 3GS and iPod Touch 4G.
As you know, iFaith helps you to save SHSH blobs on iPhone, iPod Touch and iPad running a firmware that is no longer signed by Apple. SHSH blobs offer you the possibility to downgrade or restore an iOS version that is no longer available within Apple. When users try to download to a previous version after upgrading to the latest iOS 6.1.3, they will receive an iTunes error where Apple notifies that downgrade to a previous version is not possible. However, if you use your SHSH blobs previously saved, you will be able to trick iTunes to allow you to downgrade.
I am sure that some of you might wonder why you should do this. Most people save their SHSH blobs in order to perform untethered jailbreak on their devices when a genuine tool is not available for the current iOS. It is suitable also in the case you have bricked your device in a way or another.
The new iFaith 1.5.6 includes an apticket validation in order to fix the soft DFU mode loops. You can use when you want to check to see if you have created a signed IPSW, or when you want to download existing blobs saved by Cydia. In case you do not know, iFaith automatically saves SHSH blobs within Cydia and you can find them in the “Show available SHSH blobs on server” option.
With the previous version, Cydia failed to automatically save the iFaith SHSH blobs, which caused them serious problem when trying to downgrade their devices. Now, with iFaith 1.5.6, you have the possibility to dump your SHSH blobs and use iFaith in order to create a custom firmware on Windows.
If you want to protect your device by maintaining a copy of your saved SHSH blobs, then you should definitely download iFaith 1.5.6. This is the only way in which you will be able to downgrade your iOS 6.1.3 device to a previous version. Head over to our Download iFaith page in order to download tool.
