checkra1n

Stay up-to-date with the latest news and releases of checkra1n, an unpatchable semi-tethered jailbreak based on the checkm8 powerful bootrom exploit supporting A7-A11 devices on iOS and iPadOS 12.0 and higher.

Critical bug fix for Substrate Safe Mode released for checkra1n and unc0ver users

If you’re using a modern jailbreak that uses Cydia Substrate as its primary means of tweak injection, be it checkra1n or unc0ver, then today might be a good time to fire up your preferred package manager and refresh your sources.

Substrate Safe Mode appears to have been updated to version 0.9.6003 with a critical bug fix. The checkra1n team shared the announcement in a Tweet delivered early Friday morning:

Sileo port for checkra1n discontinued, future update could Frankenstein the checkra1n bootstrap

At the end of 2019, the Sileo Team launched a botched tool that could be used to port the Sileo package manager onto the bootrom exploit-based checkra1n jailbreak. The launch wasn’t as seamless as some would have hoped, lacking synergy with the official checkra1n installer app. Moreover, it uninstalled Cydia and checkra1n resources in place of Sileo and its own dependencies with seemingly no obvious way of reverting.

Those who’ve been following the progress of Sileo for checkra1n closely may have noticed a peculiar Tweet by way of the Sileo Team’s official Twitter account early Thursday morning:

Checkra1n team launches PongoKit for checkm8-vulnerable iOS devices

The checkra1n team is best known for their checkm8 bootrom exploit-based checkra1n jailbreak tool, which just yesterday picked up support for Linux after being macOS-only for several months. We’ve known for quite some time that the checkra1n team intended to delve into more than just jailbreaking with the checkm8 bootrom exploit, and the fruits of such research are finally starting to surface.

The checkra1n team took to Twitter early Thursday morning to announce the initial release of PongoKit, a highly experimental and developer-only SDK that should help permit the deployment of other platforms on checkm8 vulnerable iOS devices:

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:

New solder-on cable allegedly permits DFU mode entry on Apple TV 4K

One of the most substantial things to happen in the jailbreak community in the past decade was the release of @axi0mX’s hardware-based checkm8 bootrom exploit. This exploit can’t be patched by Apple in a software update, and it essentially guarantees the jailbreakability of several of Apple’s devices using the A5-A11 SoC for life.

While checkm8 is already being used in the checkra1n jailbreak for handsets ranging from the iPhone 5s to the iPhone X, it’s also true that the same exploit can be used to jailbreak compatible Apple TV units. The newest Apple TV, on the other hand, purportedly sports a hidden Lightning port that would necessitate a special adapter to utilize for such an exploit.

How to get Sileo on the checkra1n jailbreak

In case you haven’t already heard, the Sileo Team’s Sileo package manager is now officially available for iOS 13 for the first time on the bootrom exploit-based checkra1n jailbreak, and it’s the first time Sileo has been made available for a jailbreak not authored by the Electra Team.

If you’re interested in getting Sileo on your checkra1n device immediately, then you’ve come to the right place. This step-by-step tutorial will guide you through the steps to do so.

Sileo is now available for the checkra1n jailbreak

It was only a couple of days ago that the Sileo Team announced the upcoming release of the Sileo package manager for iOS 13 on the new bootrom-based checkra1n jailbreak. Early morning on this Christmas Day, the Sileo Team delivered on that promise.

In an announcement shared just this morning, the Sileo Team said that users could add a custom repository to their Cydia app on the checkra1n jailbreak to find everything they would need to install Sileo on their liberated iOS 13 device:

Sileo is coming to the checkra1n jailbreak, one way or another

Much of the jailbreak community’s attention has shifted toward the new checkra1n jailbreak in recent months given just how powerful of an exploit it takes advantage of. The jailbreak is still in its public beta stages today, and its software loader only installs the Cydia package manager out of the box. But could that soon change?

An announcement shared by the official GetSileo Twitter page Monday afternoon reveals that Sileo for iOS 13 will officially ship two more days from now. What’s more is the release will commemorate the one-year anniversary of the day the first beta of the Sileo package manager project became available for testing:

Checkra1n v0.9.6 now available for public testing with an extensive change log

If you’ve been testing the checkra1n public beta jailbreak on any of your iOS devices since the tool’s availability for public testing made headlines almost three weeks ago, then you’ve unquestionably noticed the sudden stall in frequent tool updates.

As it would seem, the checkra1n team has been hard at work in crunching bugs and improving the jailbreak’s stability, and that brings us to the latest update. Checkra1n team member Luca Todesco took to Twitter Sunday morning to announce the availability of checkra1n v.0.9.6, the latest in a long line of public beta releases for avid jailbreakers who wish to take advantage of the powerful checkm8 bootrom exploit:

Understanding untethered, semi-untethered, semi-tethered, and tethered jailbreaks

If you’ve been poking around in the jailbreak community for as long as I have, then you’ve undoubtedly witnessed a plethora of different jailbreak types. Among the most popular in this community are untethered, semi-untethered, semi-tethered, and tethered, each of which exhibit different attributes that every jailbreaker should be aware of.

We understand that some are new to jailbreaking, but even those who’ve been around as long as I have might have some confusion between the different types. For this reason, we’ve compiled a quick guide to help everyone understand what each of these different jailbreaks are and how they behave.
