Unc0ver Jailbreak Update Adds RootFS Remount and Restore Support for iOS 12.4 on iPhone XS, iPhone XR

Unc0ver iOS 12.4 Jailbreak

The @pwn20wnd team is out with a new update to Unc0ver that adds support for remounting and restoring RootFS on A12-A12X devices running iOS 12.1.3 – iOS 12.4.

This does not mean that you can go ahead and successfully jailbreak your iPhone XS or iPhone XR running iOS 12.4 and install tweaks from Cydia on it. But it is a major breakthrough and brings the team behind Unc0ver one step closer to a full-fledged iOS 12.4 jailbreak for iPhone XS/XR devices.

In a series of tweets, the Pwn20wnd team also detailed just how close they are towards a successful iOS 12.4 jailbreak for A12/X Bionic devices without PAC bypass. The entire code injection method without PAC bypass is “amazingly complicated” but the Unc0ver team is getting there.

For now, the Unc0ver team still has the following hurdles before they can get around to releasing a successful iOS 12 – iOS 12.4 jailbreak for A12/X Bionic devices:

Unc0ver already has partial support for A12/X Bionic devices like the iPhone XS and iPhone XR but without code injection and tweaks support, there’s not much value in jailbreaking your device.

As of now, Chimera and Unc0ver both support jailbreaking iOS 12.4 but only for older devices like the iPhone X, iPhone 8, iPhone 7, and older. Due to the lack of PAC bypass, an iOS 12.4 jailbreak for newer A12/X Bionic devices like the iPhone XS, iPhone XR, and the 2018 iPad Pro has not been possible. However, thanks to the hard work of the team behind Unc0ver and the rapid progress they are making, this will probably change soon.
