is this a phone you have had from 6.1.3? ie is the ios/ firmware on your mac or win10 machine? instead of downloading (which is a jb using 3utools) you may be able to access the old firmware on your pc.

If this phone came with iOS 7 from the factory, I don't believe it is possible to downgrade the OS. Even though it's the same phone, I believe Apple did something with the firmware or something that prevents OSes older than the one it shipped with to work. There is a similar issue with the iPad 2.

You cant downgrade iphones to older versions if the phone has been updated.

With iPhone 4 and 4s it is doable but only if you have saved the SHSH blobs which are basically authorization keys that allow you to restore a certain iOS version that you either have or had previously.

I don’t agree with the first answer.

Apple reopened iOS 6.1.3 for iPhone 4s, you can downgrade to iOS 6.1.3. But if your iPhone 4s is 8GB 2015, you can not restore to iOS 6.1.3, cause the default factory iOS version of this iPhone 4s is iOS 7.1.2.
