I have an iPhone 6S Plus, ios 12.3.1 jailbroken with unc0ver. Everything works fine except I want to go to iOS 13 as some games no longer work on iOS 12.
I downloaded iPhone_5.5_13.4_17E255_Restore.ipsw and tried to install it with reiboot and dr.phone. (Windows 10 machine) Both give errors and unable to update. I also tried to restore my filesystem before jailbreak with unc0ver and then tried the update again, but both always fail. I’ve spent countless days on this trying to get it to work. I’m pretty desperate lol … Is there ANYONE who can help me with a working tutorial / guide ??
