How do I restore my iPhone 4S to iOS 6 (instead of 6.1.2)?
My phone has had serious issues with dropping calls since I upgraded to iOS 6.1, and then 6.1.2. I frequently get the "calls failed" message. I think the iOS is the problem, so I want to roll back from 6.1.2. I made a backup through iTunes, although I later read that you can only use a backup with the same iOS. Alright, I guess I'm just going to have to restore the phone anyway. The "Restoring iOS Software" page states that it will "restore all settings to their factory condition." I assumed that would bring the phone back to iOS 5.0, which is how I received the phone. Instead, iTunes reset the phone, then loaded 6.1.2. I DON'T WANT THAT IOS. So my question is, how can I get my phone to an earlier iOS? I don't care if it's 5 or 6, I just don't want anything 6.1.0, 6.1.1, or 6.1.2. Thanks in advance for your help.
iPhone 4S, iOS 6.1.2
