In this article, we have a great information to share with who are waiting for iOS 12.1 Jailbreak or iOS 12.0.1 Jailbreak. UMANG actually has achieved this one using his kernel exploit and tweeted a demo of it. If you don’t know let me tell you that UMANG is the part of Electra Dev team.
If you remember back in September he tweeted
Status on my vulnerabilities and a potential iOS 12.x jailbreak:
Bugs are alive and well and I’m able to successfully jailbreak my A11 and A10 devices. Can’t say about the new ones since they aren’t available in India yet.
I’m looking at a release timeline for iOS 12.1 [1/2]

after that back on October 30 tweeted that
iOS 12.1 breaks remounting / (again), and fixing it will take some time. If you want to jailbreak, stay on 12.0.1 or below for now.
My kernel bugs still work, so that’s a nice silver lining.

On November 16 Umang posted a demo on twitter which is actually a full video in which he is able to connect to another device through SSH to his device that ran his exploit. He pretty much created a bare-bone jailbreak for iOS 12.1 only to allow him to connect his device to another just was a proof of concept.
This demo has actually been done to pretty much mitigate a few complaints from other developers. Who called Umang as fake for not giving more information about the exploit or giving too little information about his exploit. The tweet quotes
Perhaps the jankiest ever demo of a jailbreak.
Unfortunately, there is NO ETA on this (or if it’ll even be released). pic.twitter.com/mAe6OANSA4

If you take a look at video his device which is running his tool. Its just a bare-bone of UI with a button but it does appear to be working for a proof of concept. After he presses the jailbreak button he gets a prompt there which tells him that he can connect to the device.
And then he proceeds to connect to the device from a tablet of some sort and he definitely is able to connect because he is able to run commands on that device. He runs that on a tablet which apparently connected to the phone does indeed split off the information for the iOS 12.1 kernel and that is correct.
He also runs the software information and he does get the information for the Apple iOS version and the build number and so on and these do match to the iOS 12.1 However, if you remember he said that remount is actually broken.
More he said that iOS 12.1 breaks remounting the root fall system again. Someone asked him how it is possible that he managed to write something to the root fall system in the video on iOS 12.1 if it is broken.
We are not sure if this was the reason why it worked for him. because when an exploit doesn’t work or a remount doesn’t work, usually installing iOS will not fix it. but he might be right because we do not have access to the code, but he seems to be very protective with his code.
He didn’t post any proof of concept or any information about where the exploit is or which function of the kernel is vulnerable or anything like that. This prompted some developers to call him as FAKE. However, that was before the demo was released and we do not know whether they maintain their skepticism at this point.
As there is not any information now to call it as fake. Umhang posted this, if it’s real and legitimate then it’s definitely a big step towards an iOS 12.1 jailbreak and 12.0.1 jailbreak and even possibly for an iOS 11.4.x. Anyways if you are running Apple iOS 11.4.1 or 11.4. I would definitely not update and stay on that version.
