need to override default sprint modem connection, please help

[buttplumber]

Hello guys,
I have the Sprint touch pro 2 which I have flashed myself and I am currently using on Metro PCS. Tonight I decided to install the new 6.5 windows update. It looks nice but when I was setting up my connection settings to use Metro PCS settings, the system always blanks out the proxy settings within a few seconds after exiting the connections tab. I installed a cab called sprint_tp2_tweaks_1, which overrides the OEM sprint settings and allows me to change to Metro PCS, but unfortunately does not allow me to go into the settings or anything. I uninstalled the tweaks cab and now I am without internet.
I need to know how to override the security which sprint has placed into this system using a reg edit tool. Thanks in advance
