How to fix some mysterious problems.

My friend has a 4S and wants to have 8.4.1 back. Whatever he does (tried multiple websites to download Ipsw from) it says incompatible firmware. Is it because iTunes is too new? If so, can someone link me a version that allows downgrade?

What is the full filename of the .ipsw he is using and its exact size in bytes?

No idea, it's from ipsw.me and there's only one 4S file

Is your friend sure he has a 4S? Have him check the size of the ipsw in bytes and verify that it's 1,560,654,758 bytes. If not, it's a corrupt download. There's no need to try multiple sites, they all link to Apple.

So it's him that's doing it wrong. iTunes can not be a problem at this point?
