Tethering can now be enabled on all Windows Phone 7 devices! Following today’s post on how to enable tethering on HTC’s WP7 handsets a friendly fellow managed to figure out a way to get it to work on the Dell Venue Pro (and tipped Pocketnow about it after they linked back to my story). There’s no need to unlock the devices here all you got to do is edit the .inf file of the HTC USB driver provided here and follow this:
The trick is to modify the driver INF files – I edited both HtcUsbMdmV64.inf and HtcVComV64.inf. Replace the HTC device IDs with VID_05c6&PID_3199. Leave the &MI_00.
To get into tethering mode for the DVP, open up EM (##634#), and go to Service Center. Switch to composite mode – password is *#301#. After rebooting the phone, unzip the driver package on your PC, open device manager, select the first unknown device (USB\VID_05C6&PID_3199&REV_0000&MI_00). Select update driver and point to the root of the two folders (it looks like it’s using HtcUsbMdmV64).
You’ll then just have to follow the rest of the instruction here (starting at 10).
