Added (1). Did this link work for you

I did this with my iPhone, took me a while to figure which way to do it, but it's very complicated.
since you can't do it in iTunes. I used redsn0w. But you need ssh blobs of the iOS 5 version of your iPhone that you would of had to of save when you where on that version.

basically, if you didn't jailbreak, or download a program to your pc called tiny umbrella which saves your ssh blobs automatically, while you were on iOS 5, then there's no way to do it.sorry.

if you did how ever, download and open tiny umbrella, get it from Internet.click on save ssh when it opens, you will see a list of all the iOS versions you have got saved, if there's no iOS 5 In there, then no can do.
if you have, just follow this video to Downgrade with ssh blobs and redsn0w.

  • Is there anyway you can download iOS 5 on an iPhone 3g? Never had an iphone but when I broke my Samsung, and didn't have any upgrades available, I decided to buy a phone off amazon. I ended up buying an iphone 3g not knowing anything about iphones. Now that my update doesn't go any higher than iOS 4.2.1 I have absolutely no apps. So did I just screw myself over? Aren't there "ways" to get iOS 5 even though my phone isn't compatible? Tried emailing iTunes already and didn't really help
  • Is there anyway you can downgrade an iPhone 5 on iOS 6.1.4 to 6.1.2? I didn't upgrade my iPhone to iOS 6.1.4, when I bought my new iPhone it was already on the firmware 6.1.3. I would like to downgrade to iOS 6.1.2 or 6.1.3 if it can be jailbroken with that firmware. I want to downgrade so I can jailbreak it. Please give HELPFUL information. Please and thank you
