Frage: restore backup 11.2.5 on iPhone with 11.1
today I got a replacement for my damaged iPhone 7Plus.
Before that I made a Backup of my iPhone 7Plus (Firmware 11.2.5).
The new iPhone has the firmware 11.1
When I try to initiate the new iPhone with the Backup iTunes says to update first.
But when I would update, then it would be 11.2.6 (because Apple stopped signing 11.2.5)
Then I would not be able to restore my Backup (11.2.5), or?
Please help me.
iOS 11.1, -
