I'm trying to use CDMA Workshop to flash my Samsung u340 to Cricket. I'm failing because the device refuses to go into DM mode.

I have no idea what I could possibly be missing; it successfully connects to the COM port and the CDMA driver is installed, but I can't seem to get the phone to respond at all - it doesn't respond to "read all", and it doesn't respond to mode switching.

I'm sorry if this is the wrong section, I searched, but I can't tell if it's the right platform.
