Updating software on iphone 3
It has just too many issues on it, and when I decided to take it to Apple store, the person said it could be a weird software glitch that I should restore as new.
If your excitement of installing the i OS 12 update which was just released was cut short by “Software Update Failed: An error occurred downloading i OS 12” error then I can understand the frustration.
Step 5: Browse and select the i OS 12.4 IPSW file downloaded earlier.
i Tunes will now begin to install i OS 12.4 on your device.
When the error popup appears, you will be prompted with two options namely “Close” and “Settings”.
Press the close button to exit the error message, wait for a couple of minutes and then proceed with installing i OS 12 again from Settings Software Update.
