I rooted my phone about a year and a half ago, since then I haven't been able to get its USB drivers to work so I can't do anything with it on my computer and I'm stuck with 2.3.6 touchwiz.
I have tried everything, including different computers/usb cords/usb ports. I got the usb port replaced, have tried installing the drivers on my computer using kies and directly.
I've tried uninstalling/reinstalling the drivers several times. Each time it tells me the driver install failed, but when I try again it recognizes that the drivers are installed. When I try installing drivers manually windows doesn't find them in the installation folder. I'm using windows 7 64bit.
