Downgrade iOS 8.4.1 and iOS 9 it can no longer be done since last night, the Apple company blocking the signing of the two versions of the operating system for installation in our iPhones, iPads and iPod Touches.
Given that iOS 9.0.2 has been released last night by the Apple company and he blocks an important vulnerability, it seems that the decision was made to additionally strengthen the security of the operating system by blocking the possibility of installing these versions of iOS.
iOS 8.4.1 was launched a few months ago, while iOS 9 it was released only 2 weeks ago, but it matters less when these versions of iOS were made available to us because the importance for Apple seems to be the impossibility of installing them.
Considering that last week there was a rumor suggesting that a 8.4.1 iOS jailbreak is ready for installation, the Apple company hastened to block the option to return to this version of the operating system, so at the moment there is no method by which you can install it on your terminals.
Downgrade from iOS 9.0.2 to iOS 9.0.1 it is still possible and probably will remain possible for the next two weeks, so you can go back to this version of the operating system if it seems to you that it offers better performance for your terminals.
