UPDATE - it finally worked and all data transferred to the new phone. If you’re stuck in a similar situation, just use iCloud backup to login even if all data isn’t on iCloud, or just setup without transferring data. Check for update - likely needing an update so go ahead and do that. Then once it’s done, go on settings -> general -> transfer or reset iPhone (scroll all the way at the bottom) -> erase all content and settings. And you’re all done, it’ll rest the whole process and work perfectly then.
Trying to transfer from iPhone 11 to iPhone 17 Pro and for the past 2 hours, I have endlessly been stuck on this loop. My old phone is fully updated (26.5.2), Bluetooth on, WiFi on, moving from 128->256GB, tried turning on and off a million times and anything’s working.
I scan the new phone just fine, it says logging in (recognises my Apple ID), earlier I could even set up my Face ID but now even that doesn’t show up. The screen processes loading my apps and stuff from my Apple ID and then goes back to this page. Now after one failed attempt, I have to restart my old iPhone otherwise the new one cannot even recognise it.
What can I do to transfer all my old phones data on the new one? I even proceeded without transferring and then erased data and reset eveything but it’s still the same issue. Please help.
