Don’t get excited about hearing the news of an iOS 12 jailbreak tool being released with Flux since it is fake. Unc0ver developer team took to Twitter to confirm that the iOS 12 jailbreak tool is fake.
Most jailbreaking teams tend to drop a major jailbreak release around Christmas/New Year. Many jailbroken users on iOS 11 were hoping for a possible iOS 12 jailbreak tool to release at the end of this year. It is this expectation that led to the fake tool being released.
There’s a fake jailbreak for iOS 12 floating around. Don’t fall for it and stay away from iOS 12 if you care about jailbreaking.

The said fake tool has already been removed. If you have already updated your jailbroken iOS 11 to iOS 12 in hopes to jailbreak it using the fake jailbreak tool, you are now going to be stuck using a non-jailbroken iPhone. With Apple no longer signing iOS 11.x releases or even iOS 12.0.x releases, there’s no way to downgrade back to iOS 11 from iOS 12. Your only hope now is that a real iOS 12 jailbreak drops soon, though the chances of that do seem very unlikely.
Some say that it was a harmless prank by the Flux developer but it has definitely not gone down too well with folks over at Reddit, with many of them seemingly losing their iOS 11 jailbreak by falling for the trap.
While there are a couple of jailbreaking tools available for iOS 11 – iOS 11.4 beta 3, a jailbreak tool for iOS 12 has not been released yet. There have been a few developments that do raise the hope for a possible iOS 12 jailbreak but even that requires a jailbreaking team to put some real hard work into using one of these exploits to build an iOS 12 jailbreak tool.
