How to save .shsh2 blobs for the Apple TV

Given the recent news that a jailbreak for tvOS 10.1.1 may be coming after all, we recently advised all Apple TV 4 owners to downgrade from tvOS 10.2 to tvOS 10.1.1 immediately before signing closes.

Hand in hand with the possibility of a jailbreak comes the necessity of saving blobs for your device, which will allow you to upgrade, downgrade, or restore your device at a later date, without worrying about signing windows. This guide will walk you through how to save blobs for your Apple TV.

Last chance to downgrade from iOS 10.3 betas and save blobs for iOS 10.2.1

The signing window for iOS 10.2.1 could close any moment now, what with the upcoming release of iOS 10.3, so this is your last chance to save your blobs for iOS 10.2.1, or to downgrade to it from the iOS 10.3 betas.

iOS 10.2.1 is not currently jailbroken, so at the moment its blobs are not of use, nor is being on that firmware a guarantee of a jailbreak. However, you never know what’ll happen, so act now! Don’t be left out in the cold when signing ends.

Possible downgrade to iOS 10.2 from iOS 10.2.1 for some users

Are you are stuck on iOS 10.2.1 or higher, having missed the iOS 10.2 signing window and therefore the Yalu jailbreak? If so, you may be in luck today, provided you have the correct setup. Early reports have come in that some devices are creating nonce collisions on iOS 10.3 b1, providing an indirect route back to iOS 10.2 through Prometheus.

For this clever workaround to come off, you must have a device which produces collisions, namely the iPhone 5s or (possibly, though not confirmed on iOS 10.3 b1), an iPad Air. If you do, you may be able to downgrade from iOS 10.2.1 to iOS 10.2 and jailbreak, by first downloading and installing iOS 10.3 beta 1, and then downgrading to iOS 10.2 using futurerestore.

How to verify your .shsh2 blobs with img4tool

We recently reported how some of the .shsh2 blobs saved with previous versions of tihmstar’s TSSChecker were faulty. One problem affected all iPhone 7 and iPhone 7 Plus blobs, rendering them useless. This issue has now been fixed going forward, though past blobs are invalid.

The other problem was more complex and affected only certain models of certain devices. It is also fixed for blobs saved from now on, but given these occurrences, it is important to be able to check whether the blobs you saved in the past are in fact valid and fit for use with Prometheus.

In this article, we’ll go through how to use another tool from tihmstar’s Prometheus suite, img4tool, to verify that your .shsh2 files are good. This method will clarify whether you are affected by the second problem mentioned above, but will also work in general, when checking the validity of your blobs in future.

TSSChecker now correctly supports iPhone 7 and iPhone 7 Plus

It seems tihmstar has been busy putting right the flaws in his suite of tools; just one week after he revealed that a bug in his .shsh2 saving tool TSSChecker had led to all iPhone 7(+) blobs saved with it being invalid, a new update restores the ability to correctly save blobs on Apple’s most recent flagship device.

How to save your .shsh2 blobs automatically online with TSSSaver

A couple of days ago, we covered how to save your .shsh2 blobs manually with tsschecker, and many of you have reported back saying you managed to successfully grab them. However, if you haven’t got them yet and don’t feel tech-savvy enough to mess around with the Terminal commands required, you can try this online tool instead which should save them for you.

How to fix TinyUmbrella v9.3.4 crashing on launch

Many jailbreakers will be familiar with the program TinyUmbrella, which has traditionally been one of the best ways to save SHSH blobs for their iOS devices onto their Macs for safekeeping. What SHSH blobs are, their function, and how to save them is outside the scope of this article, (I will put something together soon on this), but suffice to say that saving these blobs is of some importance to many jailbreakers and that TinyUmbrella has been the go-to application for doing so for a long while.

Whilst the application was updated as recently as August by its creator Semaphore, many Mac users (myself included) have noted that the new version, 9.3.4, gives an error on launch and cannot be used at all. This guide will walk you through the fix to get your umbrella back up again on Mac, so you can carry on wishfully saving those blobs.

3 ways to prepare for iOS 8.4.1

With iOS 8.4.1 currently in beta, chances are it will be released sooner than later, and Apple will follow up that release with a closure of the iOS 8.4 signing window.

Although we’ve seen nothing official regarding the matter—Apple still has yet to post release notes about its 8.4.1 beta—rumors are swirling that this update does indeed fix the exploits used in the TaiG iOS 8.3 and iOS 8.4 jailbreak.

With this in mind, it’s time to begin preparing mentally for what’s to come. In this post, I’ll show you how to be proactive and take the right measures to ensure a long jailbreak tenure on iOS 8.4.
