The checkra1n team is best known for its checkm8 bootrom exploit-based jailbreak tool for A9-A11 devices.

We’ve witnessed a plethora of teasers from Pwn20wnd and the rest of team unc0ver throughout the past week. That said, it might come off as somewhat of a surprise that the checkra1n team launched an updated public beta version of the checkra1n jailbreak Wednesday afternoon, seemingly out of the blue.

The announcement, shared first by checkra1n team member Luca Todesco, denoted that the latest version of the checkra1n jailbreak tool would be v0.9.8.1 and that it would incorporate substantial changes:

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:

Much of this past week’s news has been all about the newfangled checkra1n jailbreak for certain iOS devices affected by the checkm8 bootrom exploit, but was anyone wondering about the progress on support for Apple TV? If you answered ‘yes’ to that question, then wonder no longer.

It would now seem that an official fork of the checkra1n jailbreak tool dubbed checkra1n tv was soft released as a public beta on the checkra1n team’s official website Wednesday evening. The news was shared first by Apple TV jailbreak mastermind @nitoTV on Twitter:

The checkra1n team officially released the checkm8 bootrom exploit-based checkra1n jailbreak tool this weekend as a public beta to the masses, and while we’d seriously recommend holding off until the tool comes out of beta, we’d totally understand if you’re a bit antsy to go hands-on with things right now.

In this tutorial, we’ll be showing you how to use the checkra1n jailbreak tool to liberate a supported iPhone, iPad, or iPod touch.

Checkra1n v0.9 beta now available for public testing

Following several weeks’ worth of electrifying teasers, hacker Luca Todesco officially unveiled checkra1n, a brand-new jailbreak utility based on @axi0mX’s new checkm8 bootrom exploit for A5-A11 devices. Todesco presented the new jailbreak after taking the stage at POC2019 in Seoul, South Korea on Friday, just as he said he would, but subtle issues delayed the original launch expectation by a few days.

Checkra1n is a precedent-setting jailbreak the likes of which we have not seen since limera1n on the A4-equipped iPhone 4. Checkra1n isn’t untethered like limera1n was, but it utilizes an exploit that can’t be patched by Apple with any traditional software update, which commendably means that impacted handsets can be jailbroken for life regardless of software version.
