To do this, you will need to download the i OS firmware files directly from Apple.Here are firmware links for i Pad, i Pod touch, i Phone if needed, once you have the file you place them into the folder where IPSW files are stored locally.
To be clear, the i OS devices must be of the same type and model, meaning three different i Phone 4s can use the same firmware, but an i Phone 4 can’t use the same update file as an i Pad 2 would, and an i Pod touch can’t use an i Phone 4S update file, and so on.
Same models use the same IPSW, different models need different IPSW.
When you install i Tunes, you install Quick Time, whether you want to or not.
Here’s how to get your Windows 10 PC i Tuned: In the past, Apple has used the update “permission” to bother i Tunes users into installing Safari and putting ten new icons on the desktop.
Once there, can you double click the file and does the program install..
