I'm wanting to restore both my iPhone and iPad. I have a MacBook Pro here in front of me and i've connected each device and tried to restore but to no avail. When I try, I get an error saying my iPhone or iPad isn't the correct build and there was an error. I've then tried to "erase all content and settings" and my device goes to a black screen with that spinning loading icon in the middle. However this black screen with spinning circle in the middle remains. At first I thought it was just the iOS device doing it's thing but i've left it for more than 24 hours in this state, got frustrated, turn off and on the device and it turns back on to normal as if nothing at all happen. Nothing has been deleted from my devices at this point. And here I am now. I'm guessing this issue has to be cause my iOS devices are jailbroken, but that's all thats going on. I'm super confused. Any help is appreciated. To summarize: 1. Both iOS devices tried to restore in iTunes on MBP. But am given an error message saying, "The device isn't eligible for the requested build." 2. I tried "erase all content and settings" but the device stays stuck on the spinning/loading black screen, with no end in sight as long as 24hours so far.. 3. I have to assume it's cause my devices are jailbroken, but I can't imagine how? Perhaps a source?
