[dropcap]NO![/dropcap] an iOS 13 jailbreak for all devices, including A12 and A13 has yet to be released. For A13, this includes the iPhone 11, 11 Pro, and 11 Pro Max. For A12, this includes the iPhone XS Max, XS, XR and 2018 iPad Pro models. Currently the latest jailbreak is for iOS 12.4 in the form of Unc0ver and Chimera. Although no hacker has confirmed work on an iOS 13 jailbreak utility intended for public release, there are stirrings.
Checkm8: Permanent Bootrom Exploit for A11
Update: In a breaking new development, on September 27 (mere hours before iOS 13.1.1’s release), researcher axi0mx dropped his checkm8 exploit. Checkm8 is a low-level bootrom exploit that will lead to a permanent jailbreak on the iPhone X (A11) and lower. This is literally the biggest thing to happen to jailbreaking in the last decade! For a detailed explanation, we suggest watching the above video in its entirety.
iOS 13.1.1 Released!
Update: On September 27, Apple released iOS 13.1.1 to the public. As the second update to iOS 13 since 13.0 launched just over a week ago, 13.1.1 fixes a major keyboard vulnerability. Additionally the minor update fixes a bug correcting battery life and corrects several other small issues. For a full walkthrough and jailbreak analysis of iOS 13.1.1, we recommend watching the above video. As for iOS 13.1, iOS 13.1.1’s predecessor, for a full list of iOS 13.1 features, changes, and jailbreak information, visit our dedicated article (here). As a prelude to the jailbreak information featured here, iOS 13.1 doesn’t set back jailbreak development. It’s expected that we will get a jailbreak for iOS 13.1+
As always though, it’s recommended that you stay as low as possible if you want to jailbreak iOS 13. We don’t suggest updating to iOS 13.1 right now. More details on that here (click or tap).
iOS 13 Jailbreak Updates for A13 & A12
To determine when we may expect the first iOS 13 jailbreak, we must take a trip down memory lane. We have releases for the first Jailbreak for major firmwares going back 6 years. Starting with the oldest first, the releases are as follows: February, December, October, October again, January, February, and April. All of this to say, don’t expect a jailbreak right away. We will in fact get an iOS 13 jailbreak, but it will take time.
In fact all recent jailbreaks have made use of kernel vulnerabilities that were already patched by they themselves were released. Taking a look at unc0ver for iOS 12.1.2, it made use of an exploit Apple closed in iOS 12.1.3. So by the time unc0ver was released, it was already targeting an outdated firmware. Jailbreakers do this so they can avoid having to spend countless extra hours researching kernel (and other) vulnerabilities. Don’t get us wrong though, developing a jailbreak still takes hundreds of hours; just read one of Pwn’s latest tweets:
People underestimate the amount of work making a jailbreak takes, much less than research effort, majority seems to assume it is as simple as installing Cydia files after running an exploit and don’t realize the amount of work and complicated mechanisms they run on their devices.

A12 and A13 Jailbreak on iOS 13
As for A12 and A13 (the chips in Apple’s latest iDevices), expect a jailbreak even later. Starting with A12, Apple implemented extra security measures making it much harder to jailbreak. And it all boils down to PAC. Pwn has a nice summary for the layperson (i.e. anyone who’s not a hacker):
It is funny to me that A12 would have been significantly faster without PAC – PAC is an overhead for the system and slows down the devices for the sake of extra “security”.

So there you go, Apple has intentionally gimped performance in favor of stability on their newer devices. Of course it’s no secret that Apple is a security-first company, but this just furthers how much more difficult an A12 and A13 jailbreak will be. Good news though is that Pwn’s PAC-less jailbreak technique will still work on iOS 13 – it’s just harder to implement.
FWIW, this is one of the reasons why I never considered brute forcing PAC and went to great lengths to achieve the same thing without it—iOS13’s updated PAC implementation makes my PAC workaround more challenging than before but it absolutely doesn’t “patch it”. https://t.co/ieRFxgcd70

A13 Jailbreak: tfp0 Achieved!
As for A13, it’s expected that while the devices will have extra security mechanisms in place, PAC will still be Apple’s primary shield. Having said that, hacker iBSparkes was able to get tfp0 on A13 the same day the devices were released. A tfp0 patch basically removes a restriction that prevents a user from accessing the kernel task. The patch allows any executable running as root to call the kernel task and then modifies the kernel VM region to both read and write. So what the heck does that mean? For the layperson all you need to know is that this is a crucial step in achieving full root access and, in turn, an A13 jailbreak on iOS 13. Again, this is great news!

Jailbreak iOS 13 Release Date
To provide one final summary, expect a jailbreak after iOS 13.1 is released. iOS 13.0 is very buggy and Apple knows it. They already have iOS 13.1 in beta stages, and they certainly won’t stop there. Not once in the last 6+ years has there been a jailbreak for the first public release of a firmware. Developers like to wait for stability on Apple’s part first. This ensure the jailbreak doesn’t have glaring problems.
Once an iOS 13 jailbreak is release, it will almost certainly only support up to A11 at first. A13 and A12 jailbreak support will come in a subsequent update. Again provided Pwn and other hackers are still interested in jailbreaking the devices.
