I can not get windows to recognize my stock s3 since the JB update. I have tired 3 or 4 different usb cables all of which came with my phones.Phone is running 4.1.2. I even tired older versions of the Samsung drivers. Phones charge, but do not show up on my computer. I have tired windows 7 and 8 on two different computers. What can I do? Also tried latest version of kies. No luck.
