If you were having issuesjailbreakingiOS 13.0-13.2.3 with unc0ver initially, then this update should, in theory, rectify it.

It’s worth noting, however, that unc0ver v4.0.2 still only supports iOS 13.0-13.3 devices if they’re of the A12(X)-A13 variety. Those using A11 or older devices would need to usecheckra1nto jailbreak iOS 13 instead.

As always, the latest version of unc0ver can and should be downloaded only from theunc0ver.devwebsite.
