Checkra1n jailbreak user gets Ubuntu running on an iPhone 7

The checkra1n jailbreak utilizes such a powerful exploit that it offers a whole lot more than just a package manager and instant access to your favorite jailbreak tweaks. In fact, the hardware-based checkm8 bootrom exploit has proven more than capable of enabling a whole host of interesting hacks on compatible devices.

The latest of such hacks comes by way of Twitter user @RowRocka, who on Monday afternoon Tweeted a YouTube video of Ubuntu version 20.04 running on an iPhone 7 that had been pwned with the checkra1n jailbreak tool.

A developer launches Patreon funding seeking to bring native Linux to Apple silicon Macs

The advent of Apple silicon Macs has inconvenienced users who prefer to run other operating systems on their Mac. Several companies are currently working on Windows virtualization solutions, including Parallels, CrossOver and Docker, but what about Linux? Well, a developer has launched a campaign to fund a project to create a Linux port for Apple silicon Macs.

How to run the checkra1n jailbreak on a Windows PC with bootra1n

If you follow the checkra1n team closely on Twitter and you pay attention to the our news pieces as the team releases updates to the tool, then you’d probably come to assume that you can’t run the checkra1n jailbreak unless you have a Mac or a computer running Linux. While the aforementioned state is still technically true, you can use a helpful utility called bootra1n to run the checkra1n jailbreak on your Windows PC.

While it takes a little more finesse than simply running the checkra1n application on a Mac or a Linux box, using bootra1n is a great way to get jailbroken if you don’t have access to either of the above. In this tutorial, we’ll be showing you how to go about it, step by step.

Ra1nbox is a NanoPi Neo2-powered box that can deploy checkra1n without a computer

The checkra1n jailbreak is driven by a powerful bootrom exploit that can’t be patched with a software update from Apple, and with that in mind, it’s easy to see why some people may opt to use checkra1n over some of the other jailbreaks available, such as unc0ver for example.

While it’s a great jailbreak, Windows users have relentlessly expressed dissatisfaction about having to borrow friends’ Macs or run Linux on their machines. With no certain ETA for a Windows-based checkra1n release, third parties are now cooking up interesting solutions. One is Ra1nbox, a small and portable box powered by a NanoPi Neo2 that can be used to deploy the checkra1n jailbreak from anywhere without the need for a computer.

Checkra1n for Linux is purportedly almost complete

The checkra1n jailbreak has earned quite the impressive reputation over the past several months as it became both the first iOS 13-supported jailbreak and the first un-patchable bootrom exploit-based jailbreak to be released since the infamous limera1n days almost one full decade ago. But there’s also a certain stigma surrounding the checkra1n jailbreak as it only runs on macOS at the time of this writing.

Fortunately, that’s set to change sooner rather than later. While a Windows version of the jailbreak tool is still probably rather far off due to the complexities of its development, the good news is that the Linux version of checkra1n is nearing completion and could be released very soon. Checkra1n co-developer Nikias Bassen (@pimskeks) shared the exciting announcement via Twitter this Tuesday afternoon:

Cross-platform SHSH blob-saving tool blobsaver updated to version 2.2 with improvements

Good practice for any jailbreaker is to save your handset’s SHSH blobs regularly. Doing so opens you up to the possibility of firmware downgrades and other fruitful benefits concerning jailbreaking.

A whole host of SHSH blob-saving tools exist today, including blobsaver. The latter is a cross-platform GUI app that promises ease of use across common operating systems like macOS, Windows, and even Linux.

Saurik’s latest Reddit comment details Cydia and Mobile Substrate for iOS 11

Saurik revealed a couple of weeks ago that he was working on iOS 11 support for Cydia and Mobile Substrate, but a new comment posted on Reddit by the father of jailbreaking himself highlights that there’s a lot more going on under the hood than meets the eye.

One of the major highlights of the comment is how Saurik teamed up with a prominent developer from the jailbreak community to make all this possible. That developer wishes to remain anonymous at this point in time, but we’ll all eventually learn of his or her identity when the time is right.
