iOS downgrading

Postby Razdial » 22 Oct 2018 23:15

Hi,
I am trying to use the tool to downgrade some iPads to 11.4.1. This version is only 2 versions back, but I can't seem to get it to downgrade.
I have downloaded the right version and was building all my iPads using this .ipsw, however once Apple released 12.0 and then 12.0.1, I can't go back.
I have been through the tool and tried it different ways, so any advice would be great.
Thanks

Sorry to tell you that iOS 11.4.1 and iOS 12.0 are not signed by Apple any more. You can only restore to iOS 12.0.1 or iOS 12.1 beta version.
