If the update doesn't complete

If you're installing the update, the progress bar might appear to move slowly. The time an update takes depends on the size of the update and the number of files on your device.

When you're updating over the air, keep your device connected to a power source. If your device runs out of power, connect it to a power source and turn on the device to let the update or restore complete.

If the update never completes and the progress bar hasn't moved for an extended time, try restarting your device. Learn what to do if your device appears frozen or won't start.

Thanks for reaching out to Apple Support Communities.

Cheers.
