There are ways to save your SHSH blobs if you have not jailbroken your device, but how do you save your SHSH blobs if you have jailbroken already? You can go to Cydia’s home page to see what SHSH blobs Cydia has saved, but how do you access them? You need only download a jailbreak app known as iSHSHit – which stands for “I SHSH it.”
iSHSHit is a jailbreak app that allows you to save your SHSH blobs in case you’d like to downgrade your device in the future. According to the jailbreak description, iSHSHit lets you backup your SHSH blobs should you choose to downgrade later, and will also allow you to email your SHSH blobs to you so that you can retrieve them quickly at a later time. Emailing your blobs may be a good idea, should you ever choose to restore your device firmware for any reason (and avoid going through the same process in the future). The icon of iSHSHit is an arrow (that stands for download, and the app is the creation of developer Aaron Lindsay. You can download it for free, and it will consume 493kB of memory storage space. Select “install” at the top right of the page once you search for it, and Cydia will install it for you in less than a minute.
Once you download iSHSHit, you can then go into the app and see your saved SHSH blobs on your iPhone, iPad, and iPod Touch. iSHSHit provides your unique chip ID, as well as the model of your device (in my case, “iPod Touch 3G”), your firmware (what iOS update you are on currently), and whether your blobs are saved “via Cydia” or not. You want to check the box that says “via Cydia” in order to ensure that your blobs are saved. Press the blue “save” button at the top right of the screen if you want to backup your SHSH blobs.
If you want to save your blobs and want to save your SHSH blobs for all versions, you can change the firmware to “all versions.” However (and this is important), you may not be able to save all your firmware versions. For example, my firmware versions consist of iOS 4.2b3 and 4.3.5, for example. Unfortunately, I did not buy my iPod Touch 3G until it was updated to iOS 4.3.5 – which means that the 4.2b3 version was not backed up to my device. Next, I did not jailbreak on iOS 4.3.5 because Apple patched up the jailbreak exploits that occurred in 4.3.1, 4.3.2, and 4.3.3 – so I had to upgrade my device to the latest update on the third-generation iPod Touch in order to jailbreak it (iOS 5.1.1). My SHSH blobs, then, are only saved for iOS 5.1.1 (not iOS 5.1), as well as iOS 4.1, iOS 4.3, and 4.3.1. In the screenshot below, iSHSHit would only back up SHSH blobs for the following: iOS 4.3.1, 4.3, 5.1.1, and 4.1.
Keep in mind that, while all former iOS updates may not be saved, it doesn’t matter; the goal is to find an earlier update, should you not like where you are (or don’t like the idea of a tethered jailbreak), to return to so that you can have the jailbreak you want.
If you don’t care to download your SHSH blobs just yet, you can always manage your SHSH blobs in the second section. Just select “manage SHSH” to see what SHSH blobs are saved on your device.
Cydia is the place to go for all of the latest jailbreak tweaks, themes, and apps. Why should it not be the reference go-to source for your SHSH blobs? You may not have saved them earlier, but you can save your SHSH blobs now. Head on over to the Cydia app store and download iSHSHit now. As a small additional piece of advice, jailbreakers who save their SHSH blobs in iSHSHit can access them in iFile.
