From your explanation, it sounds like you've downloaded an app or program that has a driver conflict with the phone's operating system. You may need to flash your phone's ROM (operating system) with a new updated version to get it to work properly again. Since you didn't include who your cellular carrier is, I'm going to assume that it is AT&T. If the phone is not an AT&T Branded phone, disregard these instructions.
This phone is also called the HTC Tilt 2 (AT&T) and there is a new ROM download for the phone which should solve your problem. You'll need to follow the directions EXACTLY to flash your phone's ROM - and I do mean exactly!
This software update is intended for the HTC Tilt 2 for AT&T only
and users should not load or attempt to load this version on any other
device as it may cause serious issues/damage.
note that during the update process, the device will be Hard Reset and
anything that is NOT part of the Operating System (contacts, calendar,
music, etc) will be permanently deleted; always make a point of backing up your device's data on a regular basis!
Before you proceed, please confirm that this software upgrade is a newer
version than what is currently loaded on your device. If it is the same
version and your device is operating normally, there is no need to
reload the software.

"dies" during the upgrade process, there is a chance that the device
