Updating ipod firmware manually
After you have activated your i Pod nano, i Tunes will periodically check for software updates (or firmware updates, as they are called).
Since i Tunes performs this on a set schedule, you also have the ability to manually check for updates.
Previously, i Pod Touch users had to physically connect their device to a computer and use i Tunes to download and install an i OS update; now you can simply update your device over a standard Wi-Fi connection.
Select "General" and tap "Software update." Your i Pod Touch will now check whether an i OS update is available for download or not.
Nonetheless, it’s not terribly complicated and just about anyone can perform the procedure should they need to, if they follow instructions properly.
It’s important to point out that most users should just update to i OS 11 using the usual Software Update approach detailed here.
This walkthrough demonstrates using IPSW firmware files for updating an i Phone or i Pad to i OS 11 that is operating as usual.
Apple doesn't release updates to the operating system that powers the i Pod as often as it does for the i Phone.
That makes sense; fewer i Pods are sold these days and new models come out less frequently, so there are fewer changes to make.
And in case you need to use such file again, you can re-download it just like you did it for the first time.
i OS update files can be found at ~/Library/i Tunes, where "~" is your Home folder.
