We’ve been seeing a ton of activity over the last few weeks in the jailbreak community. And it’s coming at a time when we all thought there was no hope for another jailbreak. In fact, we thought that security researcher and hacker, Min Zheng (SparkZheng) had successfully jailbroken iOS 11.3. But then he clarified that it wasn’t a jailbreak because he “didn’t remount the rootfs to R/W and install Cydia”. He also added that it was because “Apple had added a new mitigation on iOS 11.3 in APFS KEXT”, which is what is needed to successfully bypass. But coolstar was quick to jump on the opportunity to hint that he will be releasing an update for the Electra Jailbreak. This would successfully give us a jailbreak for iOS 11.2. – iOS 11.2.6.
If that wasn’t exciting enough, SparkZheng has just revealed that he has successfully jailbroken iOS 11.3.1, the latest iOS version, and published the demo of the jailbreak. A few days back, security researchers at Tencent Keen Security Lab had also revealed that they had successfully jailbroken iOS 11.3.1 on iPhone X. Back in November last year, security researchers at Tencent Keen Security Lab were the first to demo an iPhone X jailbreak. While we doubt the security researcher at Tencent Keen Security Lab will release a jailbreak, we’re hoping that SparkZheng will provide details that will help someone like coolstar to develop the iOS 11.3.1 jailbreak. SparkZheng has also credited Twitter user @bxl1989 for the iOS 11.3.1 jailbreak in the video.
All of that said, iOS 11.4 is set to be released any moment now. And it could be the last update for iOS 11. The prudent thing to do would be to wait for Apple to release iOS 11.4, before releasing the jailbreak so they don’t also patch iOS 11.3.1 vulnerabilities in iOS 11.4. Are you still with me? If that’s the case, then coolstar should release the iOS 11.2 – iOS 11.2.6 jailbreak.
As I mentioned in my previous post, we also expect the iOS 11.2 – iOS 11.2.6 jailbreak or iOS 11.3.1 jailbreak to be a semi-tethered jailbreak like the Electra iOS 11.1.2 Jailbreak. A semi-untethered jailbreak is similar to an untethered jailbreak, it gives the ability to reboot your iOS device on its own. On each boot, the iOS device startup sequence is unmodified and it boots into its original, non-jailbroken state. However, instead of needing to use a tool from a computer to re-jailbreak the iOS device again, like a tethered or semi-tethered cases, the user can re-jailbreak their device with the help of an app running on the iOS device.
While an untethered jailbreak would be ideal, a semi-tethered jailbreak is kind of convenient, and not as bad as a tethered jailbreak. I’d like to say that I have a hard time keeping up with this in terms of the type of jailbreak that is happening, and what version of iOS is getting a jailbreak. Or is it just me? Don’t get me wrong, I am happy to see that there are options, but the anticipation and “reports” are kind of getting out of hand. That said, we will keep you updated as we learn more about these possible jailbreaks.
