Hi, I'm new here. I have a Samsung Galaxy 5 and I up until a day ago, when I used to connect the USB cable, it gave me the option of Kies mode or Mass Storage mode. Which was fine, but now after attempting to install the Kies software on my PC (which failed btw) I can't get the option of going back to using Mass Storage mode. I can't seem to find it in the "Settings" menu, even under "About Phone". Help? UPDATE:Solved. I figured that ticking the USB Debugging checkbox under Settings > Applications > Development might change sth and presto! the USB Mode select menu popped up.
