    Hi All:
    I need some help on how to activate the "Qualcomm USB mode" on this phone?

    I've tried some codes that work with other Samsung phones, with no luck so far.

    Tried the *#197328640# code, but cannot find any USB option in there.

    Another solution may be how to get the Diagnostic Port enabled in Samsung normal mode. This is an extra COM port that gets installed when connecting i637 to a PC as "Modem" (you get Samsung Modem on some COM port, and also this COM port for diagnostics)
