Recover without updating
SHSH blobs are in the process of being phased out in favour of the tougher-to-beat APTicket.
Important: For this reason, you shouldn’t upgrade the software on your phone or restoring to stock if you depend on your jailbreak for an unlock.
Many problems with the i Phone can be resolved by restarting it, but some more complex problems require putting the i Phone into recovery mode.
This shouldn't be your first troubleshooting step, but sometimes it's the only one that works.
That’s not to say things don’t go wrong, and it might surprise you to learn there’s actually a “right way” to go about doing this.
Here’s how to remove your jailbreak and restore stock i OS to your i Phone, i Pad or i Pod Touch.
If you haven’t updated your phone, maybe hold off for a little while to make sure things have all shaken out.
You can use that time to back your phone up to i Tunes and / or i Cloud — that’s something you should always do before a software update, anyway.
I use jailbreak on my i Phone to unleash all the awesomeness of my i Phone. Take a full backup of your i Phone using i Tunes and make sure you choose the backup location to your computer and also include apps in the backup.
It’s always great to use tweaks and hacks that make my device stand out from the rest. Every time a new i OS update is released, I have to manually restore my i Phone through i Tunes. I researched a lot and then I came to the conclusion that you have to bend the rules sometimes to get things done. This will make sure you don’t waste bandwidth to restore your i Phone.
Step 3: Now, select the device and the version of i OS you would like to download.
