How to do a factory reset on my iPhone without having to update iOS?

I own a 4S with iOS 7.1.2 on it and IIm about to restore it but I wouldn t like to move on to iOS 9.2 or whatever that s the latest one. I've heard some ways around it that you can like create a backup, restore and then use that backup to get the OS back, however IIm kind of sceptic about that method.

New iPhone 5s, lost game data?

I broke my old phone and I can't touch the screen. I dropped my phone and it had this pressure crack. It won't let me touch the right side of it and only the left side worked. Anyway, so due to the pressure on the screen of my old phone, it pressed random numbers as my passcode and locked me out. It's disabled and said connect to iTunes, which is stupid considering I can't connect to iTunes without unlocking my phone.

So, yeah.

On my new phone I restored a back up from December 19, 2015, but all my game data is gone! How do I retrieve it?

Step by step, please.
