If you are one of those who cannot wait for autumn to install iOS 6 You still have the possibility to go back to iOS 5.1.1 to re-jailbreak your iPad, but when the final version comes out this will not be possible if you do not have a backup of the SHSH of your iPad.
Although there is a jailbreak for the beta of iOS 6, it is not guaranteed that with the final version it can be applied RedSnow or Absinthe, at least, in the first weeks of its launch. The next iteration of Apple's mobile OS is very interesting, and surely many of you will want to try it since you are not seduced by the idea of installing iOS 6 beta on your terminals (for those who do want to do it we have prepared a tutorial).
However, there is a possibility that at launch you want try iOS 6 and then go back to iOS 5.1.1. to wait for the jailbreak. This is guaranteed by saving the SHSH blobs (Signature HaSH blobs) of a vulnerable iOS version before Apple with the new iteration closes the exploits that the jailbreak uses.
The SHSH blobs are Apple software that makes, explaining it in a very general way, that we cannot download the iOS version when we have updated. In the case of the iPhone, saving the SHSH also serves to update without losing a releasable baseband, or what is the same, use the phone with any SIM thanks to Ultra Snow.
There are several applications that allow us to make a copy of the SHSH before updating the iPad's iOS, but as we have already done in other tutorials from Tabletzona.es, we opted only for one in particular, TinyUmbrella. The reason is that it is a software with a version for both Mac and Windows and much easier to use than the other great option for this matter, iFaith, which only applies to Microsoft's operating system and requires a somewhat more complex method.
Step by step to save SHSH with Tinyumbrella
- Backup all the data on your iPad to iTunes. This is not mandatory, but you will appreciate it when you restore all your information. Simply right click on the name of your device and select the option "Save backup".
- Download TinyUmbrella for your computer (Mac / Windows).
- Open the application and connect the iPad to the computer using the USB cable.
- Click on the "Save SHSH Blobs" button. This will start the process automatically and we will just have to wait. Unlike iFaith, you will not have to put the terminal in DFU mode at any time.
Finally and after a few seconds, we will have a file with the extension “.shsh” saved on our computer, ready to be used at any time to restore the iPhone firmware.
