Running the latest version of Kies on Windows 8 64x, and Keis wont seem to let me update. It says a "firmware update" is available so I click install. It pops up the windows showing steps you need to take, etc. I accept and proceed with the update. It starts downloading firmware update components, but once it reaches 100%, it freezes for 20 seconds, then the update window disappears, and kies is stuck frozen with "Please connect a device" at the top left corner. I tried what others suggested and disconnected my phone during the download process, or turning it off, but it has no effect. The OTA update servers have also been down for 2 days now so I cant do it OTA. Very disappointed that after waiting so long for jelly bean, and it finally ariving, I still cannot update due to Samsung's incompetence.
