After I downloaded the update of iOS 8.1.3,I was unable to install it and I see "an error occurred installing iOS 8.1.3"what can I do?
Hi Josephineapo,
If you are trying to update your iPhone over-the-air rather than through iTunes, and you are having issues with installing it, then I'd like you to please follow the steps outlined below.
If you get a message that "an error occurred downloading iOS," try again later. If the issue persists, try updating your device in another network or use iTunes to update your device. Learn more about iOS updates.
Update does not complete
If you're installing the update and the progress bar appears to move slowly, be patient. The time an update takes depends on the size of the update and the number of files on the device.
When you're updating over the air, keep your device connected to a power source so that it doesn't run out of power. If your device does run 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. If you still see the issue after you restart, see what to do if your device appears frozen or won't start.
