iOS 10.2 Yalu jailbreak beta build now available

Hot on the heels of the source code being posted to GitHub yesterday, Luca Todesco has posted a very early build of the tool to his website. Work on the GitHub code proceeded quickly after its posting last night, with Todesco and others merging several commits to enable Substrate, add more device support, and streamline the tool.

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.

CoolBooter demo: the dual-boot tool for iOS

Developer Jonathan Seals recently released a new piece of work called CoolBooter, an interesting tool which allows some 32-bit devices to dual-boot different iOS firmwares. With a simple reboot it can allow, for example, switching between iOS 6 and iOS 9. Whilst this functionality is commonplace in the desktop computing world, booting multiple operating systems on iOS devices is much rarer.

Sebastien and I talked briefly about the tool on Let's Talk Jailbreak 157, and in this article I'll give some more info, as well as a video demonstration of it in action.

iOS 10.2 jailbreak could come via YaluX update

The creator of the iOS 10.1.x jailbreak YaluX has announced that he intends to update the tool, currently in beta, to add support for iOS 10.2. Luca Todesco tweeted that his solution for the instability of the early builds of his tool has tangentially allowed for compatibility with the most recent firmware, news which will no doubt delight many in the jailbreak community who are trapped on iOS 10.2, and who have been lamenting the death of the jailbreak on currently signed firmwares.

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.

Yalu + mach_portal now supports TSMC models: still unstable

Luca Todesco's beta jailbreak for iOS 10.1.x, dubbed YaluX or Yalu + mach_portal, slightly broadened its device support list recently by adding the iPhone SE (TSMC chip version) and iPhone 6s(+) (TSMC chip version) to the club. Bear in mind, we do not yet recommend the tool to the average user, and Todesco himself has spoken of the possible difficulties brought about by too many people making use of the tool in its unfinished state.

Prometheus: upcoming tool may allow unsigned iOS upgrades and downgrades

iOS hacker tihmstar has announced the upcoming release of his tool Prometheus. And no, it doesn't steal fire from the gods for you to foster the burgeoning potential of your race. Instead, he claims it will be the first tool capable of upgrading and downgrading 64-bit iOS devices to unsigned firmwares. If successful, this would be welcome news for the jailbreak community, allowing movement between firmwares for which you have saved your blobs, even after Apple's signing windows have closed.

Customizing the toolbar in your Mac Finder window

If you own a Mac, you most likely use the Finder window on a daily basis; probably more than you even realize. But one thing you may not have known throughout the eons of using the Finder interface as Apple has created it to be used, is that you can actually customize the Finder toolbar to your liking.

By doing so, you can supercharge your Finder window's functionality with additional easy-to-reach features, and we'll show you how to customize your Mac Finder toolbar in this simple tutorial.

How to Know if You Can Jailbreak and Unlock Your iPhone

I have an iPhone 4 with iOS 4.0.2 and baseband 01.59.00. Can I jailbreak? Can I unlock? I get asked this question about 20 times a day and to be honest with you, it's kinda getting old.

The good news is there is a tool available that will answer these specific questions. Just enter your device, model, iOS, and baseband version and it will tell you if you can jailbreak and unlock. Additionally, it will give you links to tools you can use to jailbreak and unlock...
