iPhone 3GS untethered bootrom exploit released

Today saw the release of a new bootrom exploit for the iPhone 3GS, an unpatchable vulnerability which gives jailbreakers total control of this device forever.

Although the iPhone 3GS is now very much a legacy device and few users will be actively using them, the rarity of a bootrom exploit makes it worthy of note. There have been no publicly released exploits of this kind since limera1n, which supported only up to the iPhone 4.

iOS 9.x Re-restore bug even more powerful than previously thought

I reported a few weeks back on an interesting new bug for 32-bit devices, which allowed you to restore them to any unsigned iOS 9.x firmware, provided you had blobs for the destination firmware.

At the time, it was thought that the bug would mainly be of use for people downgrading from iOS 9.3.5 to a lower firmware, to jailbreak with Home Depot or Pangu9. However, it turns out the bug is in fact more powerful and wide-ranging than previously thought, and may have much wider utility.

SemiRestore-Lite released with support for iOS 10.2

iOS and jailbreak developer CoolStar announced yesterday a new version of the well-known SemiRestore tool, called SemiRestore-Lite.

Unlike the full version of the tool, SemiRestore-Lite is run directly on your jailbroken iOS device, and does not require a computer.

How to add Continuity features to older Macs

Most of our readers will be familiar by now with Apple’s Continuity suite, a slew of features which were introduced with iOS 8 and OS X Yosemite. These features include Instant Hotspot, a new AirDrop, SMS/Phone calls from Mac, and Handoff. With macOS Sierra and iOS 10, they added Auto Unlock and Universal Clipboard to the group.

The catch is of course that making use of these features requires certain hardware. Therefore, Macs from before about 2010/11 appear not to support some or all of the new functionality. However, it turns out there is a way to enable Continuity on your older hardware. In this guide we’ll go through how to do it.

Saurik updates Cydia Impactor, releases Cydia Extender

Today, Cydia creator Jay Freeman (Saurik) released an update to his tool Cydia Impactor, which allows the signing and installing of .ipa files to iOS devices.

With it comes a new tool called Cydia Extender, which allows installing and re-signing of .ipa files on-device. However, don’t get too excited by this news; it is not the solution to the 7-day signing problem that many have been waiting for.

iOS 9.3.5 downgrade tool for 32-bit devices coming soon

As some of you may have seen from my tweet yesterday, there is some exciting news afoot for owners of 32-bit devices on iOS 9.

A group of developers including alitek12, ee_csw and Trevor Schmitt have stated that they are working on a downgrade solution which will allow users of legacy devices to escape from iOS 9.3.5 and return to a jailbreakable iOS 9 firmware.

How to jailbreak your Apple TV 4 with liberTV

As reported by iDB, a jailbreak for the Apple TV 4 and tvOS 9.1-10.1 was recently released by Jonathan Levin. If you’re interested in the ins and outs of his new tool, check out our article on the subject for more information.

In this guide we will focus instead on how to install the liberTV application to your Apple TV, and how to use it to jailbreak.

LiberTV jailbreak for Apple TV 4 running tvOS 9.1-10.1 released

As you may recall, a couple of days ago we reported on an upcoming jailbreak for the Apple TV 4 and tvOS 10, from macOS and iOS internals researcher Jonathan Levin. At that time the tool was undergoing some final beta testing, but as of today the wait is over, and the jailbreak has been made available to the public.

Apple TV 4 jailbreak for tvOS 10.0-10.1 complete, release imminent

As previously reported here on iDB, rumours of a jailbreak for the oft-neglected Apple TV 4 have been circulating since soon after the disclosure of Ian Beer’s Project Zero exploits, and especially since those exploits were used by Luca Todesco to fashion the Yalu jailbreak for iOS 10.0-10.2.

It was discovered soon after Yalu was released that many of the exploits used were also present on tvOS, and Apple TV developer nitoTV commented that consequently the jailbreak could be ported, with modifications, to that platform.

How to install macOS 10.12 Sierra on unsupported Mac hardware

With macOS Sierra, Apple dropped support for some of its hardware models for the first time in several years. Citing various incompatibilities and hardware deficiencies, they cut out a large swathe of machines from running Sierra. However, many Mac owners have questioned their motives, observing that some machines have made the cut whilst their more powerful contemporaries (such as the MacBook Pro) have mysteriously been left behind.

This led some to conclude that Apple is simply raising the bar to encourage hardware upgrades, and that there is often no incontrovertible hardware reason which dictates the unsupported machines. In many cases this turned out to be true, and with a few tweaks and amendments many of the “unsupported” machines have been brought back into the fold by a tool by dosdude1, called macOS Sierra Patcher. In this guide, we’ll walk you through how to use the tool to install macOS 10.12 Sierra on older Mac hardware, which claims not to support it.
