unc0ver jailbreak updated for iOS 12.0-12.1.2 [DOWNLOAD]

Developer Pwn20wnd has just updated unc0ver jailbreak with support for iOS 12 firmware. Here’s how to jailbreak iOS 12.0-12.1.2 using unc0ver jailbreak.

unc0ver jailbreak with Cydia is now iOS 12-ready

As you might already know, rootlessJB and other similar developer-centric tools lack Cydia support.

But thanks to Pwn20wnd’s relentless efforts, unc0ver is now ready for iOS 12 and that, too, with full Cydia and Substrate support.  

Though Pwn20wnd has tried to incorporate all mainstay jailbreak features, compatibility still seems to be an issue.

Preparing your device for jailbreak 

Before you jailbreak, keep the following things in mind:

  • Cydia and Substrate are fully compatible with all supported iOS 12 devices listed above. You will able to install all iOS 12-compatible Cydia tweaks after jailbreaking.
  • If you are a rootlessJB user, just follow the tutorial given below and it will get automatically uninstalled.
  • Download the IPA file beforehand and place it on your desktop if you wish to go the computer route.
