Hi Everyone,
I want to transfer my iPhone data from iOS 26 to iOS 18 version and I'm unable to do it. Can you help me to do it so I can keep my data. Is there any possibility to do this or any kind of trick?
Thank You!
Data Transfer from Older iOS version to Latest Version
You can't downgrade from a later version of iOS to an earlier version.
Think about it. Let's say there's a file that some process uses, and in iOS 18 it had three bits of data in it: A,B,C. iOS 26 added a fourth bit of data: D, so now that file has: A,B,C,D.
If you were able to take your iOS 26 data and feed it back into iOS 18, iOS 18 would need to know exactly what iOS 26 did to the data in order for it to remove "D".
iOS 18 doesn't know about iOS 26, but iOS 26 knows about iOS 18 because it knew that in that particular file it needed to add "D" in order for that file to continue working on that app in iOS 26. iOS 18 cannot use data files from iOS 26.
The only way to do what you want is to install iOS 18 and restore from an iOS 18 backup that you took from before you upgraded to iOS 26. However, that backup clearly won't have anything you've done on the phone since you upgraded to iOS 26.
However, I'm not even sure Apple are signing older versions of iOS now that iOS 26 is out, meaning you may not even be able to install iOS 18 anymore.
