Just plugged my Samsung Galaxy S2 into my PC for the first time in a few weeks and ran Kies. It told me there was a firmware upgrade which I assumed was taking me from Ice-Cream Sandwich to Jelly Bean. I did the "upgrade" and when the phone rebooted I saw that I'm running Gingerbread which is the OS that the phone shipped with. I've since rebooted the phone and PC and run Kies again hoping that it would see Gingerbread and at least put ICS back on but that didn't work. Anyone got any suggestions that might help me with this?
