I have another issue. My iPhone XS Max will not jailbreak with 4.3.1. It will only jailbreak with 4.2.1. When I try to jailbreak with 4.3.1, it always goes to the Apple logo and it will stay there until I force reset it.

Why is that? Pwn20wnd announced the latest update in a Tweet shared this afternoon, adding that it would introduce more than 30 bug fixes and stability improvements for jailbreak.

Cydia Impactor will now begin side-loading the unc0ver jailbreak app on your device:

Download whatever the latest version of Cydia Impactor is for Mac OS XWindowsLinux (32-bit), or Linux (64-bit). (These URLs will always redirect to the most recent versions, so feel free to directly link to the packages from howto guides.)

Uncover 4.3.1 jailbreak Guide

Edit: to all the folks asking about 13.3.1 support, no. Unc0ver does not support anything above 13.3.

It is based off the Time_Waste exploit which only supports iOS 13.0-13.3.0. If you wanna jailbreak a device that’s on a higher firmware. Have a Mac/Linux based PC, and have a device that uses the A11 chipset or lower, consider Checkra1n.
