It didn't show a progress on the computer. there was a brief 1 sec faint window of cmd when I hit enter for 1 sec then it's gone. I use the US version flash. Is there a difference? All i'm seeing when I press the "u" key was a faint nokia (not totally lit up like the above pic) I'm charging the battery right now. Does it usually vibrates and status light stay on for couple of seconds and the usb icon then disappear. I just did again same thing happen when I enter the file and prompt me to allow. I clicked allow and just saw a flash of cmd window for like 1 sec and disappear. No status of flashing.
