I’ve been flashing my Tilt2 for a while now, and every time, I finish flashing, WMDC fails to see my phone. Usually a reboot fixes this, but with some group policy issues, and being remote, reboots take upwards of 10 minutes. This evening I dug into it a little more, and I stumbled across a solution right from the WMDC troubleshooting guide. Pop open the device manager, expand the “Mobile Devices”, and tell it to “Uninstall” the USB sync option, unplug the phone, plug it back in. It’ll see it as a new device, reinstall the drives, and WMDC will pick up again.
