I am having a very similar issue. I am in possesion of a HTC Touch Pro, Sprint current carrier. Have downgraded rom, updated to very nice functioning 6.5+ rom, device working great. Trying to get over to Cricket network. Have prl settings, and have obtained SPC, MSL, etc. Device is not getting assigned to a port so is not being recognized my workshop 3.4, have tried to force assign the usb to a port, not having any luck. Any ideas??
