Attempting to install the official Samsung DJO7 flash for the M900. Got as far as where it tells you to connect the phone to the PC and then the PC cannot see the phone. Everything stops there. Tried manually connecting to all the com ports on the com port selector, but it said it could not connect to any of the ports. I tried it first on a Win 7 computer, then on a Vista computer. Both computers failed to connect. Does anyone have a solution?
