iOS 11 Jailbreak Status
We expect Apple to release iOS 11 on September 19, a week after the September 12 iPhone 8 launch event and the release of iOS 11 GM. While iOS 11 includes hundreds of new features and improvements such as the all-new customizable Control Center, unified Lock screen and Notification Center, all-new dock for iPad and lots more, jailbreakers will still want jailbreak iOS 11 when it is released.
So here’s an update on the iOS 11 jailbreak. But before we give you an update on the iOS 11 jailbreak, a quick update on the current situation.
Current iOS 10 Jailbreak Status
The first iOS 10 jailbreak known as Yalu (formerly Yalu + Mach Portal) was released on December 21, 2016, by well-known hacker Luca Todesco, famous by his Twitter handle qwertyoruiop. The Yalu jailbreak made use of Ian Beer’s, of Google Project Zero, mach_portal exploit. It supported select 64-bit devices such as the iPhone 6s, iPhone 6s Plus, iPhone 7 and iPhone 7 Plus.
Todesco then released a more stable version of the Yalu jailbreak tool for iOS 10.2 by using Ian Beer’s, extra_recipe exploit with the help of Marco Grassi on January 26, 2017. It supported all 64-bit devices except for iPhone 7 and iPhone 7 Plus.
You have to use a computer application known as Cydia Impactor to install the Yalu jailbreak. The jailbreak is a semi-untethered jailbreak, which means that when the iOS device boots, it will no longer have a patched kernel. You are required to run the Yalu app again, to re-jailbreak your iOS device. The other limitation of the jailbreak is that the Yalu app certificate expires seven days, so you have to reinstall it again using Cydia Impactor to renew it for another 7 days.
The exploits that were used in Yalu iOS 10.2 jailbreak were patched by Apple in iOS 10.2.1 and iOS 10.3, so it has not been possible to jailbreak iOS 10.2.1 or later.
iOS 11 Jailbreak Status
It has been a while since a jailbreak has been released. The last jailbreak was released in January for iOS 10.2 if we don’t consider the Pheonix jailbreak released for iOS 9.3.5.
The positive news is that a group of security researchers demoed a functional jailbreak for iOS 11 beta 2 firmware and iOS 10.3.2 at this year’s MOSEC (Mobile Security Conference) 2017 in Shanghai, China in June. The iOS 11 jailbreak tool that was demoed at the event seems to have been created by Liang Chen of Tencent Keen Lab.
Since iOS 11 beta has been jailbroken, we are hopeful that a jailbreak for iOS 11 could be released. Apple has released 10 iOS 11 beta versions so far, so it is not clear if they have already patched the exploit that was used to jailbreak iOS 11. It is also possible that the iOS 10.3.2 and iOS 11 jailbreak was only for research purposes. But the fact that it was jailbroken gives us hope that hackers will be able to develop a jailbreak if the exploits haven’t been patched.
It is also possible that the iOS 10.3.2 and iOS 11 jailbreak was only for research purposes, so even though it can be jailbroken, the security researcher or hacker may not release a jailbreak for it to the public. But the fact that it was jailbroken gives us hope that hackers like the Pangu team will also be able to discover the exploits and develop an iOS 11 jailbreak tool if the exploits haven’t been patched. Of course, it is still wishful thinking so I wouldn’t get your hopes too high. But let’s hope that we will finally get a jailbreak. As always, we will keep you posted as soon as there is an update about the iOS 11 jailbreak.
