I have a family member with a 3rd Gen iPad (a1416) currently running iOS 6. They need to install an app that requires iOS 7. When looking at the system upgrade page in settings, it shows iOS 9 which I believe isn't compatible and also would probably run pretty slow anyway.
Is it possible to upgrade this 3rd Gen iPad to iOS 7? How can we do that? Thanks!
PS: I've already looked at Upgrade iPad to newer (but not latest) iOS but the site mentioned in the answer there doesn't offer a signed iOS 7 image.
