I've seen other topics about this for other phones, but only one for the HTC Hero. In that, two people suggested entering a certain command from the ADB shell. enable: echo 1 > /sys/devices/virtual/usb_composite/diag/enable disable: echo 0 > /sys/devices/virtual/usb_composite/diag/enable another alternative was specifying "/dev/qct_diag_enable" instead. I tried both commands running on CM 7.2, but it ddn't work. Is there some other method that can put the Hero in diagnostic mode, so that QPST can be used?
