http://androidforums.com – I have a GT 19300 v4.1.2 and all was well until a week or so ago. W7 64-bit Now when I connect the phone to my PC (W7) the system sees it and tries to install drivers but then gives a message saying the it failed to install them. Device manager now shows my phone as an unknown device and it didn't before. I don't think this is a cable or a Kies problem, because I've installed and uninstalled Kies and tried a new cable. I haven't done a reset because many other people tried it and all it did was waste their time :-( I have the Samsung GS3 Int ToolKit and it installed the lates (General)
