On March 20, Apple stopped signing iOS 14.4, when iOS 14.4.1 was already available on the market for a couple of weeks. On March 26, he released iOS 14.4.2, an update that fixed a major security exploit so it was a matter of time before the previous version was no longer available.
And so it has been, since iOS 14.4.1 is no longer available so that Apple's servers can proceed to sign it, 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 update to the operating system that does not include any functionality, since, as I mentioned above, it is a patch to a security flaw that would have allowed outsiders to perform scripting attacks on through websites with misleading content. As stated by Apple, that failure had been exploited in the past, so he decided to close the door for good.
Always update
Although it is a minor update, since Actualidad iPhone we always recommend you install each and every update that from Cupertino they launch for compatible devices, since otherwise, our device may be affected by some type of software or malicious actions, although that does not mean that it is invulnerable.
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 the sixth beta, so its launch should not take long in time.
