[HELP] Galaxy S Advanced isn't recognize on computers
I have BIG problem. I've just bought the Galaxy S Advance and when i'm trying to connect it to computer, nothing happens. Of course phone starts charging, but nothing else. In device menager there isn't any new position. Phone works in Android 2.3.6 XXKL2 and i really want to upgrade to Jelly Bean, but I can't. I tried to reinstall many version of Kies and USB drivers, I tried connect phone to other operating system eg. Windows 7, 8.1, XP, Ubuntu 13:10 on a different computers. I tried turn on debugging mode, turn on the phone in Download mode, and I changed USB cable to another. Nothing works. Any ideas?
