A long while back I broke my old iPhone 5S, and I just got around to fixing it about a week ago. It went well, but now I'm stuck on another problem, one I haven't found a fix for yet. The phone was about to be upgraded to the newest iOS version before it got broken, and I don't remember the passcode, which I need in order to continue with the upgrade. Whenever I plug it into my computer, it isn't recognized by it. The data on the phone is what matters to me, so I can't just wipe it and start over. Any and all help would be incredibly appreciated.
