Hello folks. I have an older iPhone with an even older IOS. I have a iPhone 5s, on IOS 7. It was a previous phone of mine and I had gotten a replacement. The replacement iPhone is also a iPhone 5s. I do not like the ones that are larger. Anyway, I had jailbroken it and now wish to reset it, but it will not fully reset. It gets ½ way across with the progress bar and then reboots. The unit is then not reset. I do NOT want to upgrade to the latest IOS. I have ISPW files from previous phones and efforts for IOS 7 and IOS 8. Can I use shift-restore and use my IOS 7 or IOS 8 ISPW file and restore this iPhone to IOS 7 or 8 respectively? I wanted to check before I screwed it up. I have certain jailbreak apps I want to keep is why I am staying with older IOS. Thanks in advance. Oh, I searched, but mostly came up with iPhone 7 and how to reset with current IOS. I could not find my situation. Thanks again.
