The jailbreak of iOS 11.2 is now available but in beta, it was realized this time by a new hacker Luca Todesco who at the same time warns us not to install it because it can affect health (stability ) of the iOS!
Yalu is the name of the jailbreak for version 11.2, it is compatible with 64-bit devices, iPhone 6s, iPhone SE and iPad pro for the moment, against the iPhone 7 and iPhone 7 plus escape the rule of jailbreak because apple has already corrected the flaw exploited by the hacker on these two iDevice.
How then jailbroken your iPhone 6s, SE or iPad Pro with the jailbreak Yalu Beta?
For this you have to go to the Yalu website to download the IPA file needed for the jailbreak on this link and then the Cydia Impactor software to install the downloaded file on your iPhone.
I note at the end that this is a beta version of the jailbreak and it can crash your device, so it is better to wait for the final version!
