I have iphone 6s but am unable to install the latest ios update 15.7.3. It says ‘An error occurred while installing update’
Did someone face similar issues while installing the latest update? And how was it fixed?
Earlier iPhone models
If you are trying to update via Wi-Fi, did you try to use a PC or Mac instead?
Update your device using a Mac with macOS Catalina or later
Update your device using a Mac with macOS Mojave or earlier, or a Windows PC
If the error comes up during the install process, this might be hardware related.
Do you have enough free space on your device?
