Make sure to look at my installation video:
http://www.samsung-behold.com/index.php?topic=620.0did you correctly install all the drivers?
did you restart your computer?
update sps3?
if you are using vista, did you set it to compatibility mode?
try switching usb ports.
Make sure sps3 is closed.
Make sure your phone is set to sps mode.
If you get a communication error, restart your phone. Never drag and drop more than 1 item at a time, and never drop in a folder.
If you are seeing a P without a plus sign next to it in TK, or getting no connection to TK, follow these steps:
Plug in the phone in sps mode, open TK, open the settings window and drop down the port and see if it shows you a com(#) click that and then connect.
If anyone else has anymore, please PM me.
