Pwn20wnd developer updated his unc0ver jailbreak tool to version 3.5.6 with improved device support
Previously, SSH support for the above devices appeared, and now RootFS remounting and recovery on the same devices has been added.
RootFS Recovery on A12 (X) iOS Devices12.1.3-12.4 is especially important, because it allows these devices to safely restore to standard settings without using iTunes and without updating to the latest version of the system.
It will be very important when Apple stopsSign iOS 12.4. While this is not relevant, but Apple may at any time release an iOS 12.4 update to fix the vulnerability used by jailbreak tools.
Hacker Pwn20wnd continues to work onthe ability to install tweaks on devices A12 (X). The Chimera jailbreak tool already supports Substitute on A12 (X) devices, but unc0ver tool still supports Cydia. That is why many people use the latter and do not want to switch to the Sileo tweak manager.
The latest unc0ver jailbreak tool can be downloaded from the official Pwn20wnd repository on GitHub. You can also read the instructions on how to jailbreak iOS 12.4.
