Hello,
I just purchased today an iPhone X and sold my 7plus which was running the 11.2 beta.
I updated through iTunes the iPhone X to 11.1. However now when i try to restore it iTunes displays this message "Itunes could not restore the iPhone "iPhone" because the backup was corrupt or not compatible with the iPhone that is being restored".
How can I manage to restore it as my iPhone backup contains important things?
Thanks a lot !
