It has been just over a month since the release of the final version of iOS 11.2.5, and Apple has already blocked the possibility of returning to this version of iOS.
By now, certainly everyone knows it. If anyone of you decides and will want to go back with iOS 11.2.6 or iOS 11.3 beta to iOS 11.2.5 because it has problems with the latest system, unfortunately the installation process will not be carried out correctly, and more accurately iThe device will not activate.
At the moment, it is possible to install only iOS 11.2.6 and iOS 11.3 beta. Of course, on iOS compatible devices.
