My friend gave me her old iPhone 5 (iOS 10.3.2) which she can't remember the passcode to and I need to factory reset it from iTunes. I have tried doing this by putting the phone into recovery mode and trying to restore it but iTunes wants to update the phone to iOS 10.3.3. Because I have a poor internet each time I try to restore and update, downloading iOS 10.3.3 fails.
Is there a way to restore it without using my internet?
Cheers,
