I am trying to upgrade from Android 2.1 to Froyo. When I connect, KIES alerts me the newest firmware upgrade and I click upgrade. A window opens showing KIES preparing firmware upgrade components. Problem is (I think its a problem) KIES loses connection to the phone, the window becomes non-responsive, Cancel button is not active, nor is the X button to close the window. KIES then re-establishes the connection, but the Cancel button remains non-active. Meanwhile the progress bar is going back and forth as if it doing something but it obviously not. The only way to close the windows is using control+alt+delete. Has anyone had any similar problem doing a firmware upgrade on a galaxy s? Open to suggestions!
