"The update cannot be installed. An error occurred while installing iOS."
After you download the update and want to start the installation process, you might see the following error:
"The update cannot be installed. An error occurred while installing iOS."
This is of course very uncomfortable and therefore we would like to give you a few tips to help you solve the problem.
Tip 1: restart your iPhone
This is often the easiest way to fix a bug. So, restart your iPhone once and then try to install iOS.
Tip 2: Delete the update and download it again.
To do this, please open the settings of your iPhone and then "General". Go to "Storage". You will now find an entry with "iOS Software Update". Select the entry and confirm with "Delete update". Download the iOS update to your iPhone again.
Tip 3: do a factory reset on iPhone
If that doesn't help, the iPhone should be factory reset. Please remember to backup your data first!
We hope that one of these tips will update your iPhone to the new iOS.
