Apple just released the iOS 13.5.1 update today, which according to the announcement, is an 'important and recommended security update for all users'.
Although not described in detail about the new changes in this update, the Apple Software Updates Twitter account revealed that the iOS 13.5.1 update patched the security hole used by the Unc0ver jailbreak tool to jailbreak iOS 13.5.
Apple's support site also says that the iOS 13.5.1 update is designed to prevent applications from executing custom code with the kernel. In other words, iOS 13.5.1 is designed to disable today's jailbreak tools.
Unc0ver's jailbreal iOS 13.5 tool uses a zero-day security flaw, allowing system modification on any Apple device. However, after patching this security hole in iOS 13.5.1, this means the tool will no longer work.
Therefore, if you still want to jailbreak your iPhone, do not update to the latest version of iOS 13.5.1. Or if you've missed the update, then Apple still allows users to downgrade to iOS 13.5, and with this version, you can still jailbreak normally using the tool of Unc0ver.
Jailbreak is still a big draw for iOS users, because it allows installing applications that are not available on the App Store or paid applications. However, jailbreaking means that serious security holes exist.
