iTunes backup does not restore — iPhone stays empty
Hello,
I really need help with an important issue. I have an iPhone 14 (256GB). Recently, the phone started shutting down and restarting on its own. I updated iOS, but after the update, the phone lost network signal. A technician reinstalled the firmware, and now the iPhone works, but all my data is gone.
Before the repair, I created a full iTunes backup on my computer (about 256GB). When I try to restore it, there is no error message: iTunes shows that the backup is loading, but after the process finishes, the iPhone remains completely empty with no data at all.
I also tried restoring on another computer — the result is the same. The backup should contain very important data (photos, videos, contacts, notes, messages).
Has anyone experienced a similar issue? Is there a way to make iTunes restore the data, or at least extract it from this backup?
Thank you very much for any advice.
iPhone 14, iOS 18
