Pattern_F_ teases “Pre-Jailbreak” for iOS 14.0-14.3 as CoolStar takes interest

Anthony Bouchard ∙ February 19, 2021

Earlier in the month, security researcher @pattern_F_ from the Ant Security Lab Tweeted a demo video of what appeared to be a successful jailbreak attempt on an iPhone 11 running iOS 14.0. It was later revealed that the exploit used would potentially work on iOS & iPadOS firmware versions up to and including 14.3.

While it was unclear whether @pattern_F_ would release the aforementioned work to the general public, the news was quickly drowned out by the subsequent release of the cicuta_virosa kernel exploit for iOS & iPadOS 12.0-14.3 by @ModernPwner.

With the cicuta_verosa exploit now out for iOS 14.3 and lower, what happens next?

Anthony Bouchard ∙ February 12, 2021

Jailbreak loyalists have unquestionably heard about the brand new cicuta_verosa kernel exploit for all devices capable of running iOS & iPadOS 14.3 and below, and for what it’s worth, this is excellent news for the jailbreak community.

Given that most recent jailbreak developments have been either for that of iOS 12 or iOS & iPadOS 13-centric jailbreaks such as Chimera and Odyssey, or for the hardware-limited checkra1n jailbreak that only supports A7-A11 devices up to iOS & iPadOS 14, the announcement of this exploit’s release harbored much-needed positivity in the midst of what could only be described as a lengthy lull for jailbreak hobbyists.

Updates to futurerestore allow unsigned restores to iOS and iPadOS 14 for jailbreakers

Joaquim Barbosa ∙ Updated March 8, 2021

If you've been following our recent jailbreak coverage you'll know that there is now a jailbreak available for iOS and iPadOS 14, released by the unc0ver team. Another tool is also on the horizon, being worked on by CoolStar. However, the exploit which it uses will only work on iOS and iPadOS 14.0-14.3, not the current 14.4, nor Apple's upcoming firmware, 14.5.

The problem for would-be jailbreakers had been that iOS and iPadOS 14.0-14.3 are no longer signed by Apple, which means users could no longer move to those firmwares through traditional methods. It therefore looked like anyone who wasn't already on iOS or iPadOS 14.0-14.3 was going to miss out on the first semi-untethered iOS 14 jailbreak.

Chimera v1.6.2 upgrades userspace reboot & adds miscellaneous improvements

Anthony Bouchard ∙ February 7, 2021

Many had thought that the iOS 12-centric Chimera jailbreak tool would stop receiving updates as development efforts shifted toward newer iOS & iPadOS 13 and 14 jailbreaks, but it seems that isn’t the case.

Chimera received another update this weekend, officially bringing it up to version 1.6.2.

How to install Odysseyra1n on a checkra1n device

Anthony Bouchard ∙ January 31, 2021

By default, the checkra1n jailbreak installs Cydia as the defacto package manager, and Cydia Substrate or Substitute can be used for tweak injection. But if you’re accustomed to the Chimera or Odyssey jailbreaks, then you might prefer to use Sileo for package management and libhooker for tweak injection instead, yet checkra1n’s jailbreak method offers many benefits over relying on certificates or signed apps.

If you’re wondering whether it’s possible to install Sileo and libhooker on your checkra1n device, then the astounding answer would be yes! A script called Odysseyra1n installs the entire bootstrap on your checkra1n device, allowing you to have an Odyssey-like experience on your checkra1n jailbreak.

CoolStar updates libhooker Configurator to v1.1.0 with crash fixes, other improvements

Anthony Bouchard ∙ January 31, 2021

In case you missed it, CoolStar released a brand-new libhooker Configurator app last week so that users of the Odyssey and Odysseyra1n jailbreaks could have more granular control over their libhooker tweak injector.

In addition to letting users toggle libhooker on or off on the fly, libhooker Configurator also permitted individualized tweak toggling, disabling tweak injection for Web Pages, and individually configuring tweak injection for apps, SpringBoard, and even Daemon processes.

New libhooker Configurator app updated to v1.0.1 with bug fixes, goes open source

Anthony Bouchard ∙ January 26, 2021

Hot on the heels of an exciting new libhooker update for the Odyssey jailbreak and the subset of checkra1n devices utilizing Odysseyra1n, lead developer CoolStar is out with yet another important update that users won’t want to miss.

The latest update isn’t for libhooker per se, but rather for the brand new libhooker Configurator companion app, which grants users with powerful granular control over how and when libhooker loads its tweak injection methods on a particular device.

CoolStar updates libhooker to v1.4.0 with new configurator app

Anthony Bouchard ∙ January 26, 2021

Jailbreakers taking advantage of the iOS 13-centric Odyssey tool or the checkra1n-based Odysseyra1n bootstrap on iOS 13 or 14 will almost certainly want to launch Sileo and refresh their sources.

In a message bulletin shared to the official Sileo / Odyssey / Chimera Discord channel early Tuesday morning, CoolStar announced the release of libhooker version 1.4.0 with a host of notable improvements for users using either of the aforementioned jailbreaks.

Chimera jailbreak updated to version 1.6.1 with Userspace reboot improvements

Anthony Bouchard ∙ January 16, 2021

In a somewhat unexpected turn of events, the Chimera Team updated its iOS 12-centric jailbreak tool Saturday evening, officially bringing it up to version 1.6.1.

Chimera Team lead developer CoolStar first unveiled the release of Chimera v1.6.1 via the official Sileo / Odyssey / Chimera Discord channel.

Chimera jailbreak for iOS 12 updated to version 1.6.0 with an extensive change log

The Chimera Team released an unexpected update for its iOS 12-centric Chimera jailbreak tool this Christmas eve, officially bringing it up to version 1.6.0.

Chimera Team lead developer CoolStar announced the latest Chimera update via the official Sileo / Odyssey / Chimera Discord channel late last night, being sure to include an extensive list of changes present in the updated release.

iOS 11-based Electra jailbreak updated to v2.0 with improved bootstrap, tweak injection, & more

Anthony Bouchard ∙ December 15, 2020

Earlier in the month, Chimera Team lead developer CoolStar announced a fresh version of the iOS 12-centric Chimera jailbreak tool with support for the Procursus bootstrap, libhooker tweak injection, and a whole host of back-ported improvements that derived from the newer Odyssey jailbreak. Now, it seems the older iOS 12-based Electra jailbreak tool is receiving a similar treatment.

As shared early this morning in CoolStar’s official Sileo / Odyssey / Chimera Discord server, the Electra jailbreak has been officially updated to version 2.0 with an upgraded Chimera bootstrap with libhooker tweak injection and other miscellaneous improvements:

Chimera jailbreak updated to v1.5.1 with more bug fixes and improvements

Anthony Bouchard ∙ December 2, 2020

If you’ve been paying attention to the Odyssey Team’s Discord channel or Twitter page recently, then you’ve likely witnessed the sudden priority shift to the iOS 12-centric Chimera jailbreak – a notable departure from the team’s typical precedence, the iOS & iPadOS 13-centric Odyssey jailbreak.

The sudden attention to Chimera is no coincidence, as Chimera Team lead developer CoolStar had long envisioned back-porting the Odyssey Team’s successes with the Procursus bootstrap and libhooker tweak injection to Chimera. The team officially made it happen with Chimera v1.5 this week, and they’re out with yet another update this Wednesday evening in the form of Chimera v1.5.1:
