I rooted my D3, then installed the Wifi tether (wifi_tether_v3_1-beta6.apk - android-wifi-tether - WiFi Tether for Root Users 3.1-beta6 *** BETA *** - Wireless Tether for Root Users - Google Project Hosting). while installing this i was met with " This will install over another something.". stupid me, i hit OK. and now when ever i plug the phone into my laptop the USB mode options no longer pop up on the phone. Also, the Wifi tether nor the Wired tether work. Anyone have any ideas. I went searching for the USB mode menu in the settings, but never found them.
