Apple 5s/5c backup iOS7 shsh Tutorial (Iphone\ipad\itouch)

(1) What is SHSH?

SHSH's full name is signature HaSH blobs, Chinese: Signing certificate. SHSH is a certificate that verifies the validity of the itunes restore firmware operation. When we use itunes for the upgrade/restore firmware operation, itunes submits the ecid to the Apple Authentication server to upgrade/restore the firmware device and requests the SHSH to upgrade/restore this version of the firmware. Apple will be able to continue to upgrade/restore the corresponding version of the firmware with the SHSH by sending a SHSH certificate to the ecid for Itunes,itunes.

Simple example: SHSH is a numbered key, you need to open the number iOS7 the gate needs a key that is also numbered iOS7.

　　(2) What is the role of SHSH?

The Apple base system is the release of the new firmware, the old version of the firmware will be in a short period of time to stop validation. For example: Apple release ios7,ios6.1.3 (iOS6.1.4) will stop validation. The certificate is no longer available to obtain an upgrade/restore iOS6.1.3 (iOS6.1.4) firmware SHSH, no longer can be obtained iOS6.1.3 (iOS6.1.4) SHSH instructions can no longer upgrade/restore to iOS6.1.3 (iOS6.1.4).

　　(3) Why should the SHSH be prepared?

Need to restore Apple has turned off verified firmware, must be recovered by SHSH Backup and downgrade tool visa to cheat Apple service verification to restore the firmware that has been turned off for verification, which is the downgrade. Currently, the Downgrade tool only supports iOS devices that are processed A4: IPhone4, IPHONE3GS, iphone3g, ITouch4, ITouch3, IPad1.

　　(4) Why backup SHSH failed?

SHSH Backup requires the SHSH Backup utility to extract the MAC server's SHSH backup computer before Apple closes the firmware, but Cydia automatically backs up shsh after the jailbreak. The SHSH Backup utility will also attempt to extract the Cydia server native SHSH backup to the computer local.

Note: ios6.0~ios6.1.2 SHSH because the Cydia server for user backup SHSH algorithm problems resulting in the use of demotion, so use SHSH backup tools such as: PP Assistant, etc., extract Cyida backup out ios6.0~ The iOS6.1.2 Shsh file for the following size belongs to the extraction Cydia server for not being available.

　　(5) is the SHSH related to the jailbreak?

Shsh had nothing to do with the escape.

For example: Apple has turned off iOS6.1.2 verification, the IPhone 5 6.1.2 (not jailbreak) whether it is necessary to escape SHSH?
Answer: Can escape, do not need SHSH.
