Apple released iOS 13.3.1 back January, and as is traditional, Apple has now stopped signing iOS 13.3, making downgrading to that version of iOS no longer possible.
Apple is known to stop signing older versions of operating systems after it releases a public update, as part of an effort to encourage users to keep their devices’ operating systems up to date.
The #unc0ver jailbreak for A12-A13 will be released in the next 24 hours if no new major bugs are found.
