Save files its SHSHs

  

This is part of Apple's policy, if you wish to restore iOS on your iDevice, you can restore only the latest iOS version. This is the firmware signature system.
If you attempt to restore an older version of iOS, iTunes will display an error.

 Since iOS 4.x, signing SHSHs files appeared to allow restoration to a version of iOS not signed by Apple, which is impossible in normal times. Be aware that a SHSH file is specific to an iDevice as a unique code.
By intelligently using the saved files SHSHs, thus circumventing the protections put in place by Apple and thus restore to former firmware using iTunes.
There are ways to save your fourth SHSHs. Next if your device is jailbroken or not, you can choose to use one method over the other. And if you want to play the safety card, you can perform the backup using several of these techniques.

1. With TinyUmbrella directly from their computer and do not necessarily need to be jailbroken. (IOS 6 and iOS 8)
2. With Redsn0w, since his computer, if the iDevice is jailbroken. (IOS 6)
3. Cydia, if your device is jailbroken (iOS 6)
4. With iSHSHit, usable application if your iDevice is jailbroken. (IOS 6)
5. With iFaith (iOS 6)

We will focus only on backup solution using TinyUmbrella for iOS 8.
