On March 20, Apple stopped signing iOS 14.4, while iOS 14.4.1 had already been available on the market for a few weeks. On March 26, it released iOS 14.4.2, an update that fixes a major security exploit So it was a matter of time before the previous version was no longer available.
And it has been so since iOS 14.4.1 is no longer available so that Apple’s servers can proceed to its signature, that is, a device with this version of iOS can no longer be activated through Apple’s servers, so the only solution is to install iOS 14.4.2.
iOS 14.4.2 is a minor operating system update that does not include any functionality because, as I mentioned above, it is a fix for a security vulnerability that would have allowed third parties to perform script attacks on websites with deceptive content. As stated by Apple, this fault had been exploited
Although this is a minor update, from Actualidad iPhone we still recommend install each update
The next version of iOS that Apple plans to release is iOS 14.5, an update that includes the long-awaited app tracking feature, the ability to unlock iPhone with FaceID via Apple Watch… This update, which is currently in beta 6, so its release shouldn’t take long.
