Windows Phone 7 Tethering on the Dell Venue Pro
Begin my making sure that you have your Dell Venue Pro Windows Phone 7 device charged up, and the USB cable to hand. Also check that your carrier offers you a generous amount of data, or else this might end up as a very expensive project.
Next, download the HTC USB Modem drivers. Unzip the contents of this to a folder on your PC, and then in a raw text editor such as Windows Notepad or Notepad++, edit the HtcUsbMdmV64.inf and HtcVComV64.inf files as follows:
In HtcUsbMdmV64.inf edit:
Meanwhile in HtcVComV64.inf edit
Finish by saving your changes and then close the files. Note that you will need these on any device that you plan to use the Dell Venue Pro with.
You will then be ready to access the secret engineer screen on your Dell Venue Pro, by dialling ##634# and select Composite Mode from the Service Center. Enter *#301# as the password, and the device will restart with tethering enabled. If not, reboot the phone manually.
