Today I will show you how to use TinyUmbrella 6.01.00 to save iOS 6.0.1 SHSH blobs on iPhone, iPad and iPod Touch, iPad mini and iPad 4 to have the possibility to downgrade future iOS to iOS 6.0.1. If you need to downgrade iOS 6.0.1 to iOS 6 (5.1.1) you can use this link but only if you have needed SHSH blobs for this.
Next, I describe how to create a firmware with stitched iOS 6.0.1 SHSH blobs for any device including iPad Mini and iPad 4. You need this because if your iPhone will be updated to iOS 6.1 or higher you will be able always to downgrade it to iOS 6.0.1.
With every new iOS firmware update Apple tries to make impossible the option to downgrade iPhone to older iOS versions using iTunes (in case you have saved SHSH blobs). There are news that Apple is about to close SHSH blobs and APTicket exploits.
I think that there is no need to tell you that if you want to downgrade iOS 6, iOS 5.x versions you need to have backed up SHSH blobs of the firmware version you try to restore your iPhone’s firmware. There are several methods to save these blobs using such tools as TinyUmbrella, Redsn0w or even Cydia.
A few hours ago I wrote you news that new TinyUmbrella 6.00.00 was launched by Semaphore aka notcom especially for iOS 6 GM including all beta versions and Golden Master. Also, I wrote you that soon I would provide you with a tutorial guide on how to save iOS 6 SHSH blobs using TinyUmbrella 6.00.00. So here I made it for you.
Today was released the new version of TinyUmbrealla 6.00.00 was lunch an hour ago and you can easily to download it here using direct links. You can save iOS 5.1.1 SHSH blobs using previous TinyUmbrella 5.11.00b and restore your device without baseband updating. But this version is for iOS 6.
TinyUmbrella 6.00.00 was lunched for Apple TV 5.0.2 and all iOS 6 beta version including Golden Master. Using this tool you can update your iPhone to any iOS 6 beta preserving your old unlocked baseband, so, this means that you save your unlock and will use iOS 6. However you have to save SHSH blobs first and only then do update or restore. That’s where TinyUmbrella 6.00.00 comes in handy.
If you are iPhone user and like to have order in you stuff I advice you to backup 5.1.1 SHSH blobs. It may be needed for preserving jailbreak and downgrading iOS to lower version.
You may know that SHSH blob is a unique key or, in other words, secure hash which Apple uses to verify legitimacy of your iOS firmware. Apple allows to restore firmware until they sign SHSH blobs. But it lasts a limited time. And after that time Apple stops sign SHSH and doesn’t allow restore to any lower firmware. That’s why it is very important to save SHSH blobs for future if there will be a need to downgrade your iOS or secure future jailbreak.
The new version of TinyUmbrella 5.11.01 for iPhone 4 on iOS 5.1.1 was released today to save SHSH blobs from slightly updated iOS. Apple made a pretty strange move by releasing the 9B208 build prepared especially for GSM iPhone 4. Probably they wanted to make some slight fixes but didn’t dare to call the new build iOS 5.1.2. The only proved fact about this firmware is it doesn’t upgrade the iPhone’s baseband. However, this update wasn’t even documented.
Download TinyUmbrella 5.11.00b is very important step in using iPhone or iPad. You can easily save SHSH blobs of iOS 5.1.1 and use it for future downgrade.
It is not a secret that the main difference between every updated iOS is that there is a lot of information that changes. A lot of files are changed during updates and there arise a need to have files of lower iOS version for downgrade, for example.
As I began talking about iOS downgrade then a topic would be about SHSH blobs and TinyUmbrella 5.11.00b that would be needed to save SHSH blobs. Also you can use this link to backup blobs using iSHSit.
iSHSit is a jailbreaking tool that can save your SHSH blobs without third-party software installed on your PC or Mac (like TinyUmbrella). The app will backup the blobs directly from your iPhone and send them to Saurik’s server. As SHSH stands for Signature hashblobs or Hash signature system they need to be saved in order to perform software downgrade or a jailbreak. Those blobs were Apple’s initiative and were introduced to prevent manual iOS downgrades. But with iSHSHit app from Cydia you will easily back up those blobs within minutes directly from iPhone. Let’s see how to install the tool on your iPhone.
