It’s exciting to install a new firmware on your i OS device but you may sometimes come across a problem that will leave you disappointed.An example is the “Software Update Failed: An error occurred downloading i OS 10.3.3” error that might pop up when installing i OS 10 over-the-air (OTA).Once the process has been completed, you can restore from your backup to get back all your data and files.These are some of the solutions to fix the “Software Updated Failed” error on your device and download and install i OS 10.3.3 successfully.All you have to do is to plug in your device to your computer, launch i Tunes and then click on the update button from the Summary tab.As a last resort, you can manually download the i OS 10 IPSW file and use it to update your device.
But the upgrade is also available for existing Apple devices. Apple’s i OS 8, the latest version of the operating system for i Phone, i Pad, and i Pod, is now available.
The update will not happen if you have less than that.
On an i Pad mini with Retina Display, one warning said 6.9 GB.
This usually fixes the issue as you no longer depend on Apple’s servers to download the firmware file.
This method is recommended for advanced users as it requires you to update to i OS 10 manually.
