Linus Henze to open-source iOS 14.5.1 untethered jailbreak

German security researcher Linuz Henze is all set to open-source an untethered jailbreak for iOS 14.5.1. Here’s all you need to know about it.        

Linus Henze teases iOS 14.5.1 untethered jailbreak

Eminent security researcher Linus Henze has just announced an untethered jailbreak for iOS 14.5.1. This jailbreak is based on the following vulnerabilities – CVE-2021-30740, CVE-2021-30768, CVE-2021-30769, CVE-2021-30770, and CVE-2021-30773.

The German hacker posted the following tweet on his official Twitter handle.            

The video linked in the tweet shows a jailbroken iPhone 12 Pro Max running the Sileo package manager.  

Henze has yet to disclose more details about his untether.

This is a monumental development for the jailbreak scene, no matter how you look at it. We haven’t had a “proper” untethered jailbreak since the days of iOS 9!

For those who don’t know, the last untethered tool was released for iOS 9.1 by Team Pangu. Untethers stopped being a thing after that.

We did get a few fully untethered jailbreaks for iOS 9.3.4/10.3.4. However, those tools only offered support for legacy 32-bit devices. 

Release Date and Compatibility

Linus Henze intends to release his private untethered jailbreak in the public domain on October 21st. However, the tool, in its current form, might not be unusable for users on older operating systems. 

From what we’ve seen in the past, security researchers drop a “barebones” jailbreak in the wild, which is then developed and refined further by dedicated jailbreak developers.

Such tools also often lack package manager integration and support for all compatible firmware. 

So, if you are on a version older than iOS 14.5.1, you might have to wait a little longer than your iOS 14.5.1 counterparts.       


As far as compatibility goes, the upcoming untethered jailbreak will support iOS 14.0-14.5.1 operating systems on the current lineup of 64-bit devices.                 

Fortunately enough, Apple will keep signing iOS 14 in the future as it’s still receiving critical security updates.   

All in all, if you have an Apple device running iOS 14.5.1 or below firmware, you should be good to go!
