Whilst we recommend using the unc0ver tool for iOS 11.4.x due to its use of the original Cydia Substrate over Substitute and its greater support, we still dived in on a test device to give you a peek at the first past the post. If you really can’t wait a moment longer and have a device sitting on iOS 11.4.x, read on to jailbreak it.
7)Now all you have to do is hitJailbreakto start the process.
Remember, any errors you encounter are yours to deal with, as this is the first version of the tool, and not our site recommendation. Having said that, it worked first time for me, without a single error, on an iPhone 7 on iOS 11.4.1.
8) When the tool has run, installed Cydia, and resprung, you’ll be back at the Home Screen. You should see Cydia. Launch it.
9) Remove the repo666.ultrasnow.com repo, which may give you errors, and install any essential upgrades (whether you install Sileo we leave up to you…).
10) Finally, install a package to ensure everything is working. This will normally install Substitute and other essential packages too, which is desirable.
And there you have it! Below, you can see the Cydia homepage proudly showing my iPhone 7 running iOS 11.4.1 jailbroken, and a selection of core packages installed on the device:
