Sometimes when you try to save SHSH blobs on iPhone using Cydia server, you get problems during restore process. This issue can be resolved if you choose another program for the same task. For example, you might like to save SHSH blobs using iFaith 1.5.5 and I will show you how to do this.
This guide is good not only for iOS 6.1.2 / 6.0 users but soon (with updated iFaith this week you will be able to dump SHSH blobs of iOS 6.1.3 for future downgrade).
This is very important thing if you wish new iOS 6.1.3 and than downgrade back to 6.1.2/ 6.0 using created custom firmware in Sn0wbreeze and saved SHSH blobs. Also you can use Sn0wbreeze to jailbreak iOS 6.1.3, the new version. This method is worked for me and I will show you how to do it here.
Yesterday I showed how to downgrade iOS 6.1.3 using redsn0w but I didn’t try it myself. And this method is another way to do it but with Sn0wbreeze.
You can create custom IPSW for iOS 6.1.3 downgrade and enjoy evasi0n untethered jailbreak. The process is buggy sometimes but I tried again and again. I was restarting iTunes several times, I was re-entering DFU several times but finally I proceed with success and went back from iOS 6.1.3 to 6.1.2 thanks to SHSH blobs and created earlier custom firmware.
Now you can downgrade iOS 6.1.3 without problems because it is possible if you have all requirements fulfilled. Here below you will see how to perform downgrading process. Unfortunately SHSH blobs is the thing that is needed. So, before we start let’s take a look at the whole situation is general.
Despite the worldwide popularity of Evasi0n tool allowing to jailbreak iOS 6 and iOS 6.1.2, Apple took a decision to terminate the “season of gifts” for fans of iOS hacking. A day ago, the Cupertino company released iOS 6.1.3 update and you download it now. But if you want to keep jailbreak you need to know that iOS 6.1.3 fixed the vulnerability used by Evasi0n, and thus making the tool useless for the new firmware.
This post is for those who has accidently updated your iOS to latest iOS 5.1 and wanted to downgrade it. Why, first of all because there is no untethered jailbreak for iOS 5.1 (latest news about that read here) and the second can be your own reason to downgrade iOS 5.1 to iOS 5.0.1 and lower.
