Ask Tii - Do really need to back up your SHSH blobs

Hi Rob,

I noticed on some jailbreak tutorials there is talk about making sure you back up your SHSH blobs before you re-jailbreak or update software.  This way you can restore back to an older version of iOS.  Is this something your really need to do? Or are you ok to just jailbreak your iOS device and move forward.  

Regards,

Stephen

 

 

Hi Stephen,

Thanks for the question.

I made the decision not to mention SHSH blobs on my tutorials - as that just tends to complicate things and confuse people. 

Reality is you do not need to do it.  It is just an insurance policy where you are hedging against the dev team not being able to jailbreak the next version.  It is just needed if you want to do a jailbreak again in the future after Apple has patched the current exploit and assuming the dev team can not figure out how to re-jailbreak the new version.

So far - the Dev team has been able to jailbreak every version.  I am lazy personally and choose not to do the SHSH backup and instead place my faith in the dev team to figure out future jailbreak exploits.  

If you must must must have the jailbreak - ie if you are using your phone unlocked - then yes SHSH is important - if you are just using it for 5 icon dock and backgrounder and jailbreak is not life or death - then it is not needed to do the SHSH back up.

Hope that answers your question.
