iOS 12.4 iPhone XS Max, XR Jailbreak Unc0ver 3.5.5 Released With Proper A12 / A12X Support

iOS 12.4 jailbreak for iPhone XS, iPhone XS Max, iPhone XR unc0ver 3.5.4 and subsequent unc0ver 3.5.5 IPA download has been released with proper A12 and A12X support.

After releasing (and then pulling) partial A12/A12X device support a few days ago, the developer behind unc0ver has now pushed a new version which adds full-fledged SSH support with root-shell as well as arbitrary unsigned code execution for latest devices, although full unsigned code execution is still not supported.

So while you can get proper iOS 12.4 jailbreak now complete with root access on latest devices such as iPhone XS, iPhone XS Max, iPhone XR and 2018 iPad Pros, tweaks still cannot be installed as yet because unsigned code execution is still not fully supported by the jailbreak.

Here is official changelog of both 3.5.4 and 3.5.5 versions of unc0ver:

v3.5.4 was released for production with the following changes:

  • Add full-fledged SSH support with root-shell for A12-A12X devices on iOS 12.1.3-12.4
  • Add support for arbitrary unsigned code execution on A12-A12 devices on iOS 12.1.3-12.4 (Note: Object files will have to be signed with a CMS blob using the codesign utility)
  • Add support for running expired or revoked apps on A12-A12X devices on iOS 12.1.3-12.4
  • Fix instant or random reboots after jailbreaking with the SockPuppet3.0 exploit on A7-A12X devices on iOS 11.0-12.4

Note: Code injection is not supported on A12-A12X devices as of yet

v3.5.5 was released for production with the following changes:

  • Fixes issues with the jailbreak introduced with the last update
  • Fixes iOS 11 support

It’s important to note that iOS 12.4 is still the latest signed firmware version of iOS, which means you should upgrade or downgrade (in case of iOS 13 betas) to it while it’s still being signed in order to take advantage of the jailbreak. You can download iOS 12.4 IPSW file for your device from here. You can download Cydia Impactor for sideloading the jailbreak from cydiaimpactor.com while latest unc0ver 3.5.5 IPA can be downloaded from here.
