The checkra1n team silently updated the public beta of the brand-new checkra1n jailbreak tool to v0.9.2 Monday evening with a short list of improvements.
The latest update incorporates bug fixes and adds official support for 'no substrate mode' for troubleshooting jailbreak extensions in the event of crashes or respring loops. The full change log for checkra1n v0.9.2 is as follows:
Not even 24 hours after the initial public beta release of the checkm8 exploit-based checkra1n jailbreak tool, the checkra1n team has already launched its first bug fix update dubbed v0.9.1.
The newest version of checkra1n was announced only minutes ago via the checkra1n team’s official Twitter account:
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.
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.
Hacker and checkra1n team member Luca Todesco took the stage at POC2019 in Seoul, South Korea early Friday morning to talk about checkra1n, an upcoming checkm8 exploit-based jailbreak tool that would work with A5-A11 devices. But perhaps more intriguingly, sporadic teasers indicated that the tool would be released sometime after his presentation there.
The last official update we have from Todesco himself is that the checkra1n release was delayed longer than expected following the presentation, but it was still supposed to launch sometime today. With the day now over and still no official checkra1n jailbreak launch at the time of this writing, you wouldn’t be alone if you were twiddling your thumbs and wondering what was happening.
If you’ve been following the development of the checkm8-based checkra1n jailbreak all this time, then you’ll be excited to hear that one of the project’s most vocal developers, Luca Todesco, took the stage at POC2019 in Seoul, South Korea to discuss the jailbreak and reveal particularly captivating details about the checkra1n team’s members, long-term plans, and more.
Todesco entitled his Keynote presentation “The One Weird Trick SecureROM Hates,” and from what we can gather, the checkra1n team is comprised of the following members, many of which might be familiar to veteran jailbreakers:
Despite the recent and controversial announcement that Sileo’s development had been ‘suspended until further notice,’ project lead developer CoolStar appears to have since overturned that declaration. Thursday evening, CoolStar announced a second update to the alternative package manager since that announcement, formally bringing it up to version 1.5.2.
Surprisingly, the official @GetSileo Twitter page didn’t make mention of the latest Sileo update, but it’s worth noting that CoolStar posted a memo about it not too long ago in his official Discord channel:
Apple closed the signing window for two different iOS versions for various handsets Wednesday evening, including 13.1.2 and 13.1.3.
It’s regular practice for Apple to stop signing older versions of iOS after a newer release has been available for some time. Doing so both prevents software downgrades by the jailbreak-savvy and encourages software updates for everyone else to ensure users take advantage of the latest features and security patches.
The Electra Team’s Chimera and Electra jailbreak tools have long utilized Substitute for native tweak injection, but it now seems that this could be on the verge of changing.
Electra Team lead developer CoolStar took to his jailbreak-oriented Discord channel on Thursday to share that his team would no longer maintain Substitute due to its incompatibility with certain jailbreak tweaks and hooking limitations:
The upcoming checkm8 exploit-based checkra1n jailbreak has been making rounds in headlines over the last couple of weeks, with some of the most exciting news involving tweak injection on iOS 13. But as you might recall, a recent teaser also showed that the checkra1n jailbreak would support several package managers, including Cydia and Zebra.
People were particularly excited to see support for Zebra in addition to the tried and true Cydia package manager, but it begged the question about compatibility with other popular package managers, including Installer and Sileo, just to name a few.
Things are getting particularly interesting in the world of jailbreaking since the official public release of @axi0mX’s checkm8 bootrom exploit for A5-A11 devices. One of the most intriguing work-in-progresses involving checkm8 has been checkra1n, a jailbreak tool spearheaded by renowned hacker Luca Todesco and others.
While we’ve witnessed quite a few teasers involving the checkra1n jailbreak to date, none have been quite as exciting as one shared just this morning. Jailbreak developer Sam Bingner, well-known for his popular TetherMe jailbreak tweak for enabling native Personal Hotspot on jailbroken handsets with or without carrier consent, teased the tweak functioning on iOS 13 by way of checkra1n:
It was just last week that Sileo Team lead developer CoolStar announced a controversial development hiatus for the Sileo package manager on the Chimera and Electra jailbreaks. But in an unforeseen turn of events, another update was released late last night.
As shared by the official @GetSileo Twitter page, Sileo v1.5.1 is now available for users and brings new bug fixes and improvements to the app’s user experience:
