I have windows and the GS3 phone. My carrier is AT&T and I'm trying to upgrade my firmware on my phone. ATT only allows you to do so by connecting the phone to the computer and using Kies.
When I connect my device and begin upgrading, it prepares to download the upgrade and then, due to settings, my computer asks for permission to actually begin downloading. I say yes, Kies turns grey (like when there is a pop up that you have to close) and nothing happens.
I've talked to samsung live chat, and called them. they couldn't resolve the issue. I'm pretty much left with having to take the phone to ATT and having them do it, which would wipe everything on my phone.
