Chosen Solution
I would like to know if is possible to install older iOS on iPhone 4S. This thing is important because I’ve got an iPhone 4S with 9.3.5 iOS and I noticed that this iOS is really slow, so I would like to downgrade to iOS 7.0 but I noticed that this is not possible because Apple didn’t sign iOS 7.0 or 7.0.x. So, what is the solution? If Apple didn’t sign an iOS, but if I’ve the file of iOS 7.0.x is possible with another software downgrade actual iOS to iOS 7.0.x? Thank you in advance for reply.
If Apple isn’t signing the OS it’s impossible to downgrade to a non signed iOS. There isn’t a good way around this, either. Update (11/26/2018) So that’s what this is all about?
